The second is a web accessible directory defined in apache to reach the created maps. sample: 11111111.png = map created. location: D:/webdevdata/ms_tmp/11111111.png you can access it with your browser at: http://localhost/ms_tmp/11111111.png Got it? But you have to define the directory /ms_tmp/ first in appache: see your httpd.conf files and add something like this: Alias /ms_tmp/ "D:/webdevdata/ms_tmp/" AllowOverride None Options Indexes FollowSymLinks Multiviews Order allow,deny Allow from all that's it. This said, don't loose your time to configure paths and other things. Download the latest version of ms4w at www.maptools.org : apache, php, php-applications are configured. Try www.cartoweb.org. That's very enhanced too! Hope this helps.

In particular I was thinking of using the WCS to serve netCDF data, filtering on temporal dimensions, and dataset parameters (not doing any geographic subset as yet). My questions are; 1) GDAL seems to have problems with netCDF, would I be better to translate to geotiff where each band represents a dataset parameter? 2) Has anyone done something similar? Quoting from the WCS howto Only spatial, simple temporal and radiometric band subsetting is possible with the current implementation Does that mean I would have to convert to geotiff to support querying by dataset parameter, since each band could represent a different parameter? Any help on the time dimensions would be appreciated. Are there any examples (however small) I could look at.

Norman, Translating to GeoTIFF would likely give you a more stable situation to work from. However, I am planning to improve netCDF support in the coming month or two. > 2) Has anyone done something similar? You might want to look at the GALEON interopability experiment which aims to serve similar data by WCS from netCDF files. Aspects of it are already working - but they aren't using MapServer as a backend for the WCS. http://my.unidata.ucar.edu/content/projects/THREDDS/GALEON/GALEON-Activity-Plan.htm > Quoting from the WCS howto > Only spatial, simple temporal and radiometric band subsetting is possible > with the current implementation > > > Does that mean I would have to convert to geotiff to support querying by > dataset parameter, since each band could represent a different > parameter? Any GDAL dataset that supports arbitrary bands could be used. There isn't anything special with GeoTIFF. But you may have to do some substantial work to build tile indexes which allow subsetting on a variety of conditions. Hmm, I think this is one of the reasons Steve did the tileindex layer type, so that you could install a filter condition on a tile index. I think I had better shut up and let Steve speak.

Message-ID: Like so many others, I've used the circle symbol with various sizes to draw my lines for the past few years. The results have been pretty good, but the aliasing on the roads has always bothered me, especially when the true-type labels are beautfully anti-aliased right beside them. I recently read in the archives that the relatively new cartoline symbol supports anti-aliasing. However, when I use the cartoline symbol and turn antialiasing on, the lines drawn are still aliased. I'm using Mapserver 4.5 on Windows XP with the latest GD library. Is there something in my setup that is preventing the cartoline from being anti-aliased? Does someone have an online example that shows the cartoline symbol being anti-aliased? The pertinent sections in my symbols file are: SYMBOL NAME 'road' TYPE CARTOLINE ANTIALIAS TRUE END SYMBOL NAME 'roadov' TYPE CARTOLINE ANTIALIAS TRUE END And in my mapfile: CLASS STYLE SYMBOL 'road' SIZE 5 COLOR 255 0 0 ANTIALIAS TRUE END STYLE SYMBOL 'roadov' SIZE 3 COLOR 255 255 255 ANTIALIAS TRUE END ....

Message-ID: I'm having difficulties using pixmap symbol from mapscript (current CVS version), I wonder if someone had experience with a similar problem ? I wanted to have rotated pixmap (bitmap) symbols on my map, however AFAIK mapserver does not support rotated symbols. I thought I could make prerotated bitmaps which I would put in symbolset and use classes to show the proper symbol. However, this needed the increase of the MS_MAXSYMBOLS define (I tried with 1000) after which mapserver would hang indefinitely if the symbolset itself contained somewhere over 300 symbols (I also tried playing with MS_MAXSTYLES and MS_MAXCLASSES in map.h to no avail). Alternatively I wanted to generate the symbols dynamically from mapscript, however looking at the docs I see no reference to the possibility of creating bitmap symbols (even though the MS_SYMBOL_PIXMAP constant does exist). As a last resort I tried to generate a temporary symbolset file which contained only the needed symbols for a certain map extent and load it with $map->setsymbolset(), but regardless of the number of symbols it contained, it hang, but ONLY if the symbols defined inside were of PIXMAP type. I did not managed to dig up anything relevant in the list archives. Any ideas ?

In-Reply-To: Message-ID: Hi James, The documentation states that 'antialias true' within the symbol definition is just for truetype fonts, 'antialias true' in the style affects both truetype fonts and cartolines. Try your map with no antialias statement in the symbol or in the style, then compare the results with 'antialias true' just within the style. I just started using the cartoline symbol for roads myself, and I can see a good difference ... still a little jaggy, but a good difference. Perhaps the 72dpi resolution of the output image is keeping the jaggies visible.

In-Reply-To: Message-ID: I've been using cartolines for a while. I think you need to specify antialias in the STYLE for a class, not the symbol. The antialias in the SYMBOL definition (as Ken Lord said) is for truetype fonts. Oh, not paying attention to your example, I see you do say antialias in the style. Hmm, foggy... memory... try specifying the linecap, linejoin and linejoinmaxsize in your symbol, I think I may have had problems when I didn't (all mine do now), even if you specify same as the defaults. It's been a while since I used the antialias for cartolines, tho - I think it's a bit slow, or the quality wasn't all that great (I believe it's done by GD?). And if you still use normal lines also in a map, there will be a mix of aliasing and antialiasing. I switched to a different method that gives accross-the-board antialiasing - design and draw the map at 2x or 4x size with no antialiasing anywhere, then use PHP's image functions to resample the image with antialiasing. I find that the antialiasing produced this way looks much better, closer to what I expect from using graphics programs, even for font rendering. Requires PHP-MapScript of course, and a bit of programming, but it works fine. Unless you have a fast processor, the 4x will be pretty slow, but it looks better. I even use this method for generating high quality PDF output, instead of using mapserver's builtin PDF output.

Message-ID: Thanks for the suggestions, I really appreciate them. So far, no worky. I removed the 'antialias true' from the symbol file, no change. I removed the 'antialias true' from the style area, no change. I re-added the 'anti-alias true' to the style area, and set the linejoin type in the symbol file to round, the linecap type to round, and linejoinmaxsize to 3... and the edges of my lines and corners got rounder, but no change in the aliasing. I then removed all layers except for the layer in question, removed the background color set for the whole map, removed the projection settings, removed all the labels, so that I was down to a simple single layer and there still is no change in the aliasing. I even tried to get antialiased single-pixel width lines to work by not using any symbol reference or size parameter: MAP ... LAYER TYPE LINE DATA "myshapefile.dbf" NAME "roads" COLOR 0 0 0 STYLE ANTIALIAS TRUE END END ... END Even this did not work-- my single pixel line was still very much aliased! In the archives, I noticed at least one other fellow could not get the single-pixel line anti-aliasing to work, and wonder if this issue is related to the cartoline symbols not being anti-aliased. Any other ideas out there? Could this possibly be some sort of bug?

This works great as long as the map contains at least 1 feature from the layer. It seems that if the map is zoomed out too far (LabelMaxScale or MaxScale in effect) or the area of interest does not overlap any features from that layer I get this fatal error: Fatal error: Failed writing image to stdout in /usr/local/www/data/myscript.phtml on line 875 Attempt to suppress the error by preceding the function call with an ampersand: [@$img->saveImage("", $mapImg)] still allows the script to end prematurely How can I solve this problem? Testing the scale before calling saveImage could be a partial solution. Perhaps there is a layer or map property that I can check before calling saveImage()?

Only layers from one of the services are displayed. If I choose to draw just layers from either service, there is no problem. The same mapfile running on same version of Mapserver on my windows machine works fine. So I suspect a config/library problem with Mapserver. It's affecting all versions of mapserver I have which is why I suspect it's a required library. This is a Linux machine. A different Linux machine we have is working normally. I don't even know where to look for the problem. Can someone please tell me what component we can try re-compiling/configuring to fix the problem?

My experience: I built an AMD64 box as a GIS workstation, mostly running PostGIS/GEOS/GDAL/ QGIS/GMT. Shuttle system with socket 939 3500+CPU, 1Gb memory & 2x 80GB SATA drives with software RAID. (I needed something luggable to take to sea regularly) My major problem was hardware support, with Mandrake, SuSE & Fedora all having problems with SATA controller/drives. Ubuntu installed & ran faultlessly, however, and the QGIS development team have some Ubuntu fans who have put together some instructions for Ubuntu QGIS users, which includes GDAL. Also, Lingis (which includes GDAL) is currently being updated, & will be released for AMD64 (& SuSE 9.1/9.2/9.3) in a month or two. I decided to install from tarballs & compile from scratch to avoid dependency issues, and have no problems so far with Postgres/PostGIS/GDAL/GEOS/shapelib/ QGIS/GMT/ImageMagick all compiled from source on a 64bit system. About 4 weeks of perfectly stable running so far Prior to running Ubuntu I had good success with SuSE 9.1/9.2 and Lingis, all 32 bit. Totally stable & (IMHO as a GIS technophile :-) very fast. All the major distros (& even M$) are improving AMD64 versions, packages are becoming readily available and the platform is very fast. Strongly recommended, even if used as just 32bit.

I believe I read about someone on the user group doing this. Ross, The above is possible, but would require alot of additional programming. I suspect Tom was looking for a solution that didn't require him to do too much programming. To the best of my knowledge the only "live access" mechanism would be the one via FMEObjects that Bart mentioned. But I would strongly encourage Tom to just pre-convert his files to shapefiles using something like FME.

Don, The most common problem with tileindexes is related to how MapServer internally builds the path to the file from the path to the map, the "SHAPEPATH", the path to the tileindex shapefile and the path within. I don't actually know for sure how it is supposed to work, but I would suggest you just use absolute paths inside your tileindex. This can be accomplished by using absolute paths when you invoke gdaltindex. Of course, this might not be the problem. You may also find it helpful to follow normal debugging mechanisms, turning on debug, using shp2img, etc. Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, warmerdam at pobox.com light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent From lucamarle at GMAIL.COM Fri Apr 1 14:23:57 2005 From: lucamarle at GMAIL.COM (luca marletta) Date: Sat, 2 Apr 2005 00:23:57 +0200 Subject: jBox image problem In-Reply-To: <8b502010504011423a5589b2@mail.gmail.com> Message-ID: Welcome into the club Lluis.

Message-ID: All, Is there a way to have the zoom value max out at some value, where the map can't be zoomed out any further, or even in the reverse, where the user couldn't zoom in past a certain point. Not just not display (as with the MIN/MAXSCALE values in the MAP file, but not to even have the scale of the map go beyond an upper or lower threshold. What I would like to do when these upper and lower thresholds are reach is to simply pan and recenter the view from the picked area. Basically not zoom out any further than the reference image for example. I'm using the CGI version of MapServer. Maybe someone has a trick up their sleeve for this. bobb From dbkeon.ml at GMAIL.COM Fri Apr 1 22:24:20 2005 From: dbkeon.ml at GMAIL.COM (Dylan Keon) Date: Fri, 1 Apr 2005 22:24:20 -0800 Subject: Limiting a zoom.

Thus $rs has to be populated in $polygons # something like foreach ($polygons => $poly) { # Draw the $poly onto the image } In essense, how do I get the shape information of polygons from the database using mapscript. Thanks in advance,.

I am running Apache 2.0.53. I have run the demos successfully. This is my first attempt with my own dataset.

This is a very simple example using only one data layer, a vector file. You can download the datafile yourself from the USGS National Atlas. The URL for this layer, the US States Boundaries in Shapefile format, is http://edcftp.cr.usgs.gov/pub/data/nationalatlas/statesp020.tar.gz.

This example also draws some unprojected, static text. You can use this technique to label your maps: apply titles, timestamps, or copyright information.

Seems to me that 250MB is about all you can expect for $20 a month. Did you see python-hosting.com? They don't mention PostGIS, but might be persuaded to install it. They also claim to have Zope (shared or dedicated), Plone (shared or dedicated), Webware, Twisted, CherryPy, SkunkWeb, Quixote, Spyce, Cheetah, mod_python I don't know anything about their services other than what I read from their site. cheers, Sean -- Sean Gillies sgillies at frii dot com http://users.frii.com/sgillies From wouter.schaubroeck at GMAIL.COM Sun Apr 3 13:45:27 2005 From: wouter.schaubroeck at GMAIL.COM (Wouter Schaubroeck) Date: Sun, 3 Apr 2005 22:45:27 +0200 Subject: WMS GetCapabilities problem Message-ID: Hi all, I'm using the ms4w application you all know.

I never did figure out the PHP part of that installation - it got too cryptic and I couldn't follow Now, I see that there is a new set of files that I *may* be able to install (i.e. post by William K) - if the instructions include any human readable english (sorry, I'm really not up on all of the Terminal language, but I'm trying) Any words of wisdom? Is there any set of how-to's that are in basic english out there? I would like to take advantage of having apache installed, and maybe do a tutorial or try out some GIS locally on this machine.

I get the following exception after 3 or 4 calls to the private member function drawMapImage(): System.NullReferenceException: Object reference not set to an instance of an object. at mapscriptPINVOKE.mapObj_draw(IntPtr jarg1) at mapObj.draw() at SimpleMap.Form1.drawMapImage() My drawMapImage() member looks like this: private void drawMapImage() { try { m_img = m_map.draw(); m_img.save(@"E:\Web\Data\console.png", m_map); Console.WriteLine("Image saved!"); } catch (Exception e) { Console.WriteLine("Exception:\n" + e); } } The contstructor for this form contains the two following lines: m_map = new mapObj(@"E:\Web\Data\road.map"); m_img = m_map.draw(); I've got no idea of where to go from here. I've tried local definitions of the m_map and m_img objects and explicitly disposing them. I've even forced the System.GC.Collect() method in an attempt to clean any unused objects up.

The problem i have is i want to create some classes in a layer like : LAYER ... DATA geom from
CALSSITEM "gps_date" TEMPLATE "dummy" ... CLASS EXPRESSION "/2005-04-04.*/" END ... END I thought that this expression give all points of a day but it seems that some other points are returns too. I saw it because when i do a queryByPoint i see that gps date is older than my expression date..... Does this layer def seems good ? Another question : When i do a queryByPoint, i can query some point that are not shown on the map. I don't know how it's possible but maybe i have to add a template on each classes but not in the layer ? Will try ( i just think of it) Thanks From stephane.riff at CERENE.FR Mon Apr 4 01:26:02 2005 From: stephane.riff at CERENE.FR (=?ISO-8859-1?Q?St=E9phane_RIFF?=) Date: Mon, 4 Apr 2005 10:26:02 +0200 Subject: class expression on date field In-Reply-To: <4250EFD3.8090104@cerene.fr> Message-ID: I solve the problem :) In fact if you make some classes in a layer with a template when you query this layer the expression filter doesn't apply to the query. You must add template to each classes and remove it from your layer.

I would have assumed that you would want to provide a visual view into the data with mapserver rather than providing direct access to the underlying data via WFS. WFS clients are rare, and it would likely take a sophisticated user to make much use of a WFS feed. I may be misconstruing your intentions, but I would suggest you focus on building a mapserver application using either MapServer in CGI mode, or perhaps as a mapscript application, based off your shapefiles. If you have alot of data it might make sense to load it into PostGIS. One nice thing about putting it in PostGIS is that you can efficiently do queries based on time or other parameters whereas if you do this from a shapefile all features are read each time (though non-applicable features can be easily discarded). Are you wanting folks to have an easy way of entering new information and to correct existing information? This will add some complication to your work, but I would still suggest addressing this as a mapscript operation. It is more important though in this situation that you load your data into PostGIS as updating a shapefile in-place is pretty difficult.

Let me explain what I'm trying to do I guess, and what I hope this function can accomplish... I have a bunch of addresses complete with latitudes and longitudes in a database (it's just a postgres table, I'm not using PostGIS). I read the locations from this table and I plot points on the map at those locations, colorcoding them by various criteria. I then want to be able to click on those points and bring up another web page specific to those sites. When I first started this project, I looked at queryByPoint but couldn't figure out how to use it so I used another method... I turned the map into a client side image map, converting the projected lat/long values into pixel values and making those points clickable. However, this method breaks down when you zoom in on the map too far. It works for a while, but at when zoomed in past a certain point it no longer works and makes the entire map link to one point. I'm not sure why this happens, but it's very repeatable and I can't see anything in my code that would cause this effect. So, i'm back to looking at how queryByPoint works. My points are drawn in a layer created in mapscript, it doesn't initially exist in my mapfile. There is no shapefile associated with the points and thus there is no dbf file associated with them. The only thing I have is the postgresql table from which I'm reading the locations. I'm not sure if this is something queryByPoint can access. from the documentation: The query is performed on all the shapes that are part of a CLASS that contains a TEMPLATE value or that match any class in a layer that contains a LAYER TEMPLATE value. I'm not sure what this means... what should the template value be, and what exactly is the query? Is it just an SQL query? Do I need to be using postGIS or another spatially enabled database to do this? Mode is MS_SINGLE or MS_MULTIPLE depending on number of results you want. Passing buffer <=0 defaults to tolerances set in the map file (in pixels) but you can use a constant buffer (specified in ground units) instead. Where do these results go? The function only returns an integer that tells me whether it had success or failure, so how do I access the query results? I guess that's enough questions for now... thanks in advance for any pointers. -Jeff -------------- next part -------------- An HTML attachment was scrubbed...

Ideally, one would like to think of a tileindex as representing a tree of data that is modular. Like an object that can be instantiated into multiple maps. Or moved around within a data directory tree without have to rebuild the tileindexes with every move. So also requires clear rules about how the DATAPATH, DATA, TILEINDEX, and the path in the tileindex interact with one another when they are either absolute or relative paths. If this is not clear please write a bug against documentation on the mapfile reference to make this clear. Here is what I think the rules SHOULD be: 1) if DATA or TILEINDEX path is abosulte then look for the DATA or TILEINDEX at that location 2) if DATA or TILEINDEX path is relative then absolute it to the DATAPATH and look for the DATA or TILEINDEX at that location 3) if the contents of the TILEINDEX are absolute, then use that path 4) if the contents of the TILEINDEX are relative, then append it to the location of the TILEINDEX file 5) if a relative DATA path item also exists in a LAYER with a TILEINDEX, then append it also the the contents of the TILEINDEX 6) if it is absolute DATA path item also exists in a LAYER ignore it as this has not logical connotation or raise an error. Note: 5) is important if you have a TILEINDEX that represents an area like a county, and you want to use the DATA to select the layer data from a county, so I might have TILEINDEX "tiger/counties" DATA "street" that generates paths like: tiger/counties/01/001/street and TILEINDEX "tiger/counties" DATA "landmarks" that generates paths like: tiger/counties/01/001/landmarks I opened this bug on this in sept 2002 http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=204 -Steve W.

There's a fix in the CVS version of the code, but for now just search the listserv archives for the terms 'queryByPoint' and 'index' to find some other threads regarding that bug. As for queryByPoint, here's a function I wrote for getting the closest points from a layer. It may be overkill for your situation, but at least it should demonstrate how queryByPoint works. It will return multiple results in an array sorted by distance from the queried point. It also reprojects the points to a projection that uses meters as units so that I can calculate a distance of miles instead of DD or whatever. Before you can query the layer, you'll need to set a template value for your layer. This doesn't need to be a real template, just something to keep mapserver from complaining. Just do something like $layer->set("template", "dummy"). function get_closest($layer, $longitude, $latitude, $min_number_results) { global $map, $meter_to_mile; // create a new point object to test against $point = ms_newPointObj(); $point->setXY($longitude, $latitude); $layer = $map->getLayerByName($layer); // toleranceunits do not need to be in the same units as the projections $layer->set("toleranceunits", MS_MILES); // loop through, increasing our search radius by 1 mile each time until we find some matches $tolerance = 1; $max_tolerance = 30; // won't search for points further than 30 miles away $found_flag = false; while (!$found_flag AND ($tolerance < $max_tolerance)) { $layer->set("tolerance", $tolerance); $layer->queryByPoint($point, MS_MULTIPLE, -1); $num_results = $layer->getNumResults(); if ($num_results >= $min_number_results) { $found_flag = true; } else { $tolerance++; } } // if no results, return -1 to signify an error if ($num_results == 0) { return -1; } else { // clone the point $temp_point = ms_newPointObj(); $temp_point->setXY($point->x, $point->y); // project cloned point to NAD83 / Illinois East so that our calculated distance are in meters, not dd $temp_point->project(ms_newprojectionobj("init=epsg:4326"), ms_newprojectionobj("init=epsg:26971")); // loop through our results and add them to our return array $layer->open(); for ($i=0; $i < $num_results; $i++) { $result = $layer->getResult($i); $shape = $layer->getShape($result->tileindex, $result->shapeindex); // reproject our shape to the same projection as our cloned point $shape->project(ms_newprojectionobj("init=epsg:4326"), ms_newprojectionobj("init=epsg:26971")); $distance = $temp_point->distanceToShape($shape); $distance = round($distance * $meter_to_mile, 2); // add the data to our array $return[$i]['distance'] = $distance; $return[$i]['shape'] = $shape; } $layer->close(); // sort our multidimensional array on 'distance' foreach ($return as $val) { $sortarray[] = $val['distance']; } array_multisort($sortarray, $return); return $return; } } From mikesaunt at GMAIL.COM Mon Apr 4 08:13:30 2005 From: mikesaunt at GMAIL.COM (Mike Saunt) Date: Mon, 4 Apr 2005 16:13:30 +0100 Subject: Zooming to a coordinate position Message-ID: Hi All I'm a MapServer / MapScript newbie and also am implementing through the c# interface.

The essence of zooming is setting the map extent. Look in mapscript/swiginc/mapzoom.i for the C code of the zoom* methods.

The issue is with mapserver not having access to set the 'index' value for the shapes you're adding in. With no index values, queryByPoint won't work at all. See the bug report on it at http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=806 It's been fixed in the CVS version apparently, but for now, try grabbing the modified version of the php_mapscript.c file linked on the bug report and use it to recompile mapscript (v 4.4.1). You should then be able to do $shape->set("index", $index). Just FYI, the indexes you set can not be arbitrarily assigned. They must be set in the same order that they are added to a layer, starting with 0 and incrementing by 1. Otherwise, queryByPoint() won't work. Hence, I would start with an empty layer, so that you know to start your indexing at 0.

I'm having a strange issue. I wanted to experiment with creating a large mapserver image and then use the php image functions to resize and antialias it as I'd seen mentioned last week in a thread. However, after recompiling php and adding the following options (--with-gd --with-png-dir=/lib --with-jpeg-dir=/lib --with-zlib-dir=/lib) my mapscript is broken. PHP gives an error of "Call to a member function saveWebImage() on a non-object". What's strange is that if I leave all of my layers with a status of off, everything works peachy. As soon as I turn on any of my layers, though, things break. If I recompile PHP without the gd stuff, things run smoothly again. Mapserver isn't logging a thing, and the mapscript ms_GetErrorObj isn't giving me any clues, either. gd, libjpeg, libpng, and zlib (along with devel packages) were all installed from rpm. I'm running on Suse 9.1 with Mapserver v 4.4.1. If anyone has any clues on what might be happening, I'm all ears.

This was just an itch I was scratching, but I'd be happy to feed it back into the code. My main question here is how do I do that: is there a CVS repository? Do I mail in patches? To whom? Regarding the gradient coloring, it works like this: you choose a numeric field in your data (I've tested with PostGIS, but anything you can use for classitem or labelitem should work), and create a style like this: STYLE COLOR 60 60 60 MINCOLOR 0 0 0 MAXCOLOR 255 255 0 MINVALUE 0.0 MAXVALUE 300000.0 GRADIENTITEM "sale_price" END That takes the sale_price field from the shapes values, maps its value to a percentage between MINVALUE and MAXVALUE and then picks the color that's appropriate from the color range. For a quick snapshot of how this looks, I've mapped relative size of parcels (as a percentage) to these colors: MINCOLOR 127 29 200 #Purple MAXCOLOR 255 255 0 #Yellow You can see the results here: http://www.binko.net/gradient.png As I said, this is still in the proof of concept stage, and I haven't tested against any rendering except GD (although in theory it should work). Any help on future direction and how to contribute back would be appreciated.

In-Reply-To: <16264e07050404150252e55088@mail.gmail.com> Message-ID: Well, I don't use the PHP-included GD with PHP. of course, I don't use imageantialias. let's see, here's an outline: 1. mapfile is set up 2x size, say. Use the usual map->draw and mapimage->savewebimage to get your temp image and a URL for that. 2. transform the image URL to a file path and load the image with imagecreatefrompng(), or whatever format you used 3. create an empty image with the target image size (imagecreatetruecolor()) 4. scale the loaded image into the empty image - imagecopyresampled 5. save the resampled image over the Mapserver-generated temp file A few notes: Since there is not control over scalebar line weights, I draw a scalebar manually and merge that with the resampled image before saving it. The same goes for legends (I use an html legend). And maybe for other embedded image items. You need to scale image coordinates received from user clicks back to the 2x size before sending them to MS zoom functions. Set everything in the map file to draw without antialiasing, including type and symbols from fonts, or they will come out a bit thin. Of course, you need to create symbols and patterns based on images at the larger size. The larger the initial image, the longer it takes MS to draw it (scaling and loading aren't affected as much). I find that 2x size gives a good speed vs. image quality balance, but 4x gives a better image if you have the CPU power.

Since this is also mapserver oriented and the questions are general in nature, I'm hoping I might get some suggestions here. First, I have to say getting PostGIS up and running on freeBSD was very easy so Kudos to the port maintainer and freeBSD. Also get data loaded and get mapserver running with PostGIS was not nearly as hard as I had thought it might be and I'm really liking what I see, even if I'm not sure what to do with it all yet. Also getting mapserver running was just as easy. What I have done (and I will try to get you a link soon to see it) is load up the Census zipcode polygons and some of the Census summary File 1 and 3 data and I can generate some thematic maps. Questions: 1) What are your thoughts on loading all Tiger into PostGIS versus keeping most of it in shapefiles and only using some of the data out of PostGIS? Performance? Are there other benefits to put it all in PostGIS? If I had it all in PostGIS, are there other cool features that I could have that I don't now with shapefiles? 2) What is the best way to scale or other map an attribute column into a known range for use with mapserver CLASS EXPRESSIONS. The Census data has literally thousands of columns any of which you might want to select as the basis for a thematic map, or even some expression of multiple columns. Conversely, a mapfile would have some fixed number of classes that would say render you polygons as say shades of color based on the attributes. Has anyone done this? anyone have any ideas or suggestions on how to do this? I realize that 2) is slightly off topic, but any help would be appreciated.

All the hits, and demographic information is coming out of postgres and the zipcode polygons are in postGIS, and placenames basemap layers are coming out of shapefiles. http://swoodbridge.com/test/postgis-maps.php This is an attempt at displaying hits by zipcode and comparing that against income or population by zipcode. The income and population values are scaled into 8 percentiles ranges and used to color the zipcode polygons. The hits are scaled into 8 ranges and used to display the circles or asterisks and sizes from small to large. In the first row of maps, I only display the top ranked hits. On rows 6+ the size of the font displaying the zipcode indicates the range of the hits. This still needs more work to figure out how to best display all this information at the various scales. And for that matter what is useful from an analysis point of view. I have hundreds of tables of demographic information, I would like to know how to correlate the hits against the various tables to find out if any of them a particularly significant or not. Open to any ideas suggestions or pointers.

Flavio, Well this depends on the need for performance, and the organization of the data. Even spatial unindexed datasets can be quite performant if split into tiles and tileindexed for instance. And of course, many interesting datasets are small enough that reading the whole thing isn't too bad.

General procedure would be opening up a bugzilla entry and add the patch as an attachment, and then send out a short e-mail to the mapserver-dev list with a link to the bug report. The bugzilla entry can then also be used to discuss the final implementation. There is a Mapserver CVS, although only the (core) developers have CVS write access. So probably one of the developers with CVS write access should apply your patch/feature (after they agree with the implementation ofcourse).

This was just an itch I was scratching, but I'd be happy to feed it back into the code. My main question here is how do I do that: is there a CVS repository? Do I mail in patches? To whom? Regarding the gradient coloring, it works like this: you choose a numeric field in your data (I've tested with PostGIS, but anything you can use for classitem or labelitem should work), and create a style like this: STYLE COLOR 60 60 60 MINCOLOR 0 0 0 MAXCOLOR 255 255 0 MINVALUE 0.0 MAXVALUE 300000.0 GRADIENTITEM "sale_price" END That takes the sale_price field from the shapes values, maps its value to a percentage between MINVALUE and MAXVALUE and then picks the color that's appropriate from the color range. For a quick snapshot of how this looks, I've mapped relative size of parcels (as a percentage) to these colors: MINCOLOR 127 29 200 #Purple MAXCOLOR 255 255 0 #Yellow You can see the results here: http://www.binko.net/gradient.png As I said, this is still in the proof of concept stage, and I haven't tested against any rendering except GD (although in theory it should work).

I've decided that, for my page, I'm simply making a decision on what the users can get at. HOWEVER, I believe a php-based page could render a new mapfile on the fly while allowing column selections, and you could then work it by calling that new mapfile. I've not tried that.

H?vard, While the idea of generalizing this to generating a set of classes has merit, I don't think it is suitable when you use Bill's method of putting the controls in a STYLE. In fact, Bill's approach is to say that there would only be one class for gradient fill (what I would call color ramped) and that it is implemented as a specialized rendering style but STYLES are nested inside a single class. So we can't very well have a class with a style that generates a set of classes. At the very least it would be very confusing. Of course we could just call these "subclasses" breaks, but then you still end up duplicating alot of the descrete class mechanism. Better to just manually or though mapscript create a set of descrete classes if that is what you want. I certainly do like Bill's original approach for continuous gradient fill. In addition to using it for the rendering, I would also like legends to know how to show a gradient fill styled class as a color ramp with min, max and perhaps some intermediate values. Of course we will also need some control over how these legend entries are generated. PS. I would be interested in implementing the same STYLE mechanism for rasters if you changes make it into CVS. But we would still need someone to tackle the legend support.

There are a variety of possible situations, but if I had large DWG files, I would likely still want to translate them even if I could use them directly for the very reasons you mention. Also, depending on the nature of the DWG files, it might be very advantagous to setup a customized FME processing pipeline to translate the files into a format more suitable for direct mapping use. Spliting out just the data needed, and organizing it into sensible layers. I'm not really very familiar with DWG, but in DGN files (another CAD format) I have often found files to be organized in a way somewhat foreign to my GIS background. A translation operation can be helpful to regroup things, and through away extraneous stuff. Also, FME no doubt offers more sophisticated DWG support and transformation options than any general purpose OGR driver ever would. But I can still imagine a case where an organization might have thousands of DWG drawings in a database, and want to be able to pull any one out based on some criteria, and display it as a map. In that case, on the fly rendering might be better than trying to keep them all up to date. In any event, since we don't currently have DWG support, translation is pretty much the only option - or the FMEObjects link though that certains adds additional complications and performance overhead.

One of the features I've considered (but haven't implemented yet) is an "INCREMENT" command. That would allow you to provide a fixed numbers of colors and would be a simple modification. I really like the continuous colors though, so I think the default for that would be "0". :) Regarding how to break it up, I think a first pass would just let you do something like this: STYLE MINCOLOR 0 0 0 MAXCOLOR 255 255 0 GRADIENTITEM "foo" MINVALUE 0.0 MAXVALUE 100.0 INCREMENT 20.0 END That would give you 5 steps from black to yellow. Another thing you should be aware of is that I'm using PostGIS layers as the data sources for these. That lets me do 'real' manipulation of the data realtime before it gets mapped. So I can do a complicated select that maps values to things like log scaling etc. and I don't have to add support into mapserver for it. I just thought I'd mention it as there are some that might like a more flexible (and complicated) solution here. > I certainly do like Bill's original approach for continuous gradient > fill.

The mapserver style could become an unwieldy object, and user data could become littered with *ITEM fields. I assert that there is nothing demonstrated here by Bill Binko that can't be accomplished by N classes and simple legend filtering. These N classes and filtered legends wouldn't have to be edited by hand, they could be generated using any flavor of mapscript. Don't take this the wrong way, Bill, I'm not dissing your creativity and hard work. I'm not actively opposed, just wanting to make sure that unintended consequences are considered. Additionally, "gradient fill" is not the right term to use for this new concept. A gradient fill is generally understood to be the painting of a single polygon or region with a smoothly varying color. I know you understand, Frank, I am just pointing out that it would be best to head off possible confusion.

Please remember, this is not gospel and may be dropped/rewritten -- I've gotten no feedback from Stephen Lime or others yet. If you want to try this out and your using linux/unix/bsd/etc., go to the bug at: http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1305 Download the patch (gradient.patch.gz) and save it in your (virgin) mapserver-4.4.1 source directory. run: $ zcat gradient.patch.gz | patch $ make clean all install as you normally do (in my case, I just copy the mapserv to my cgi-bin directory). Then you can add several new elements to your mapfiles: STYLE GRADIENTITEM "fieldName" #Must be numeric (float/int) MINVALUE 0.0 #The low end of the data values MAXVALUE 100.0 #The hight end of the data values MINCOLOR 255 0 0 #A color to match low values MAXCOLOR 0 255 0 #A color to match high values COLOR 0 0 0 #A dummy color - some parts of the #code won't draw without this # - I'll fix it later :-) END If your value is lower than MINVALUE, it will get the MINCOLOR (likewise for MAX). Values between MIN and MAX will get mapped (linearly) between the MINCOLOR and MAXCOLOR. I find that using the Gimp to make some simple linear gradients helps me pick good colors. I'll add INCREMENT in the not too distant future and update the patch.

This has been a frustration of mine also. We can get text angles from attributes but not set colors from attributes (without defining lots of classes). Granted a "color" is actually three values for RGB and not a single value. I had thought about another way of doing something similar that could be used with attributes easily. That would be to define a named color table using your ideas for ramps, or discrete color entries. The to reference the named table and an attribute column. COLORTABLE "foo" MINCOLOR 255 0 0 MAXCOLOR 0 0 255 STEPS 10 END COLORTABLE "bar" COLOR 255 0 0 # 0 COLOR 238 0 0 # 1 COLOR 221 0 0 # 2 ... COLOR 0 0 0 # n OFFRANGE 0 255 0 # color to display if the index is out of range END Then in a layer be able to reference it along with an column COLORTABLEITEM "bar" "attribute" Or something along these lines. I am glad that you actually implemented a prototype and it is generating a lot of discussion. I think it shows the need for this kind of feature. > I'm sure there are currently solutions to this: I just think this works, > and makes life much simpler. To claim that this will make mapfiles > unwieldy seems a bit backward: doing this now is clumsy. If our mapfiles are getting unwieldy, then maybe it is time to rethink them in general. I know this is heresy, because so much of mapserver code it tied to the structure of the mapfiles. But they have experienced a lot of growth over the last few years and if we want to experience continued growth as our community grows and the needs grow we need to be able to add features like this. Some of our most experienced users are working about the limitations and restriction in mapfiles today by using the C preprocessor and other tools for automatic generation of mapfiles, based on their needs. Anyway, something for our developer to think about. -Steve > That said, I'm open to suggestions on better ways to structure the file > elements!

There are cartographical rules to support such an approach. Mapserver currently provides built-in mechanisms that are conveniently used for rendering layers based on nominal / qualitative (discrete) attributes. LABELSIZEITEM can also be used to control size in a rendering based on a quantitative attribute (STYLEITEM?) It is not very complicated to do customized rendering using the basic mechanisms and Mapscript, but since quantitative attributes are so common, it would be nice to have built in support for rendering maps based on them. Mapscript is for power users. It would also be nice to have built-in support for legends for renderings based on quantitative attributes. For layer rendering based on quantitative attributes, what we need to define is a CLASSITEM (which is already there). In addition we need to specify the method for classifying and rendering based on this item/attribute. The CLASS object is currently a very central component of the LAYER object. Classifying and "rendering" could be done by using a "dummy" CLASS object with a STYLE object that specifies the rendering (as proposed in this thread). This is, as Frank points out, confusing, since classification is performed in the STYLE object of a CLASS object. Another approach is use some (new?) kind of style object (perhaps a new name is needed?) that is a direct member of the LAYER object. Since new elements of the STYLE object now have been suggested that do not have a use for non-quantitative attributes, it could perhaps be just as well to introduce a new concept at the LAYER level instead? Classes could then be defined using the current (discrete) CLASS approach or the "new" approach, depending on the level of measurment of the attributes that are used for the LAYER rendering. This is probably not a trivial enhancement, and something for the wish-list. What I am worried about is that such a future development could be blocked by the introduction of the "light-weight" gradient colouring support. Just some thoughts/ideas...

Shapefiles are very fast if they are set up correctly and indexed. You would be wise to understand and resolve the performance issues before moving the data to mysql as it is not likely to be faster. For example do all you shapefiles have *.qix file? How is your mapfile structured? Are you trying to draw too much detail at larger zoom values? When is it slow? Zoomed in or zoomed out or both. If we had some more information we might be able to help you resolve the performance issues.

Have you searched the archives for tiling & indexing shapefiles yet?

This does not make sense in the MapServer context. GDAL client support for JPIP was incorporated some time ago but I could never get it to work very well. I have no immediately plans to pursue that further. > 3) Finally if anyone knows how to implement the temporal dimension in the WCS I would > be grateful!! Steve Lime has examples of this up somewhere. Hopefully he'll follow up on this. But you might find info in the WCS topic in the wiki. > OpenGIS announced an initiative to put GML coverages inside Jpeg2000 which is interesting, but > I just want to serve the data at the moment, and use the XML inside the Jpeg2000 to hold a scaling value > since Jp2k can't hold floating points. Getting the scaling value into the JP2K file will require some custom work for you both on the server and the client. I am interested in carrying scale and offset values in GML coverages in J2K files but haven't started to explore that. I only just recently added support in GDAL for reading and writing them in GeoTIFF (in a custom tag). Even with that done, it still doesn't kick in with MapServer since MapServer doesn't try to copy that sort of metadata into the generated map. Perhaps we will eventually need OutputFormat options to attach extra metadata to output files.

I am sorry to say that I didn't know there was a ".qix" file. With my database background, I assumed that an indexed database field would be faster than a flat file. Of course, that is correct if the flat file is not index. I searched through the archives and found out what a .qix file was all about. I created one for each of my shapes and sped up download time by 50%.

It uses the method of drawing the map at a larger size, then uses php mapscript to sample the image back down. It scales all of the symbols, etc up and down as necessary. It also renders any annotation layers and the scalebar seperately and then combines that over the antialiased map so the text isn't blurred. Therefore, you won't have to go through and manually scale all of your .map entries or worry about scaling your click points or anything. It's pretty self contained. The .map file needs to output the image as png initially, so that the background is transparent. PHP needs to be compiled --with-gd. It's called like this: $image_url = antialias(2); where the two denotes to draw the original map at twice the size, then scale it down. The scale can be increased for higher image quality, but it will of course take longer. -Camden /////////////////////////////////////////////////////////////// // // function antialias() // // draws our map at a larger size, then samples it back down to provide // antialiasing. annotation layers and the scalebar are drawn seperately // and combined over the resulting image, so that they are not distroted. // // using this function, all labels must be drawn as seperate annotation layers. // // the .map file should be configured to output as png for transparency. // /////////////////////////////////////////////////////////////// function antialias($scale) { global $map, $root_directory; // get the dimensions of the image $image_width = $map->width; $image_height = $map->height; // scale the map up $map->set("width", $image_width * $scale); $map->set("height", $image_height * $scale); // turn off the scalebar if there is one $scalebar_present = false; $scalebar = $map->scalebar; if ($scalebar->status == MS_ON) { $scalebar->set("status", MS_OFF); $scalebar_present = true; } // loop through our layers, and if it's status is on, loop through the classes scaling the sizes for ($i=0; $i < $map->numlayers; $i++) { $layer = $map->getLayer($i); if ($layer->status == MS_ON) { for ($j=0; $j < $layer->numclasses; $j++) { $class = $layer->getClass($j); for ($k=0; $k < $class->numstyles; $k++) { $style = $class->getStyle($k); // scale the size and offsets $style->set("size", $style->size * $scale); $style->set("offsetx", $style->offsetx * $scale); $style->set("offsety", $style->offsety * $scale); // for symbols with styles and points in them, we need to scale those as well $symbol_id = $style->symbol; $symbol = $map->getsymbolobjectbyid($symbol_id); // symbol style $points = $scaled_points = $symbol->getstylearray; for ($l=0; $lsetstyle($scaled_points); // symbol points $points = $scaled_points = $symbol->getpointsarray; for ($l=0; $lsetpoints($scaled_points); } } } } // loop through and turn off our annotation layers for now, keeping track of them $labels = array(); for ($i=0; $i < $map->numlayers; $i++) { $layer = $map->getLayer($i); if ($layer->type == MS_LAYER_ANNOTATION AND $layer->status == MS_ON) { array_push($labels, $layer); $layer->set("status", MS_OFF); } } // draw our image $image = $map->draw(); $image_url = $image->saveWebImage('MS_PNG', 1, 1, 0); // create our image objects $old = imagecreatefrompng($root_directory . $image_url); $new = imagecreatetruecolor($image_width, $image_height); // the background color gets dropped from our transparent pngs, so start by filling our new image with it $back_color = $map->imagecolor; $back_color = imagecolorallocate($new, $back_color->red, $back_color->green, $back_color->blue); imagefill($new, 0, 0, $back_color); // resample the image back down to the original size (antialiasing it) imagecopyresampled($new, $old, 0, 0, 0, 0, $image_width, $image_height, $image_width * $scale, $image_height * $scale); // scale the map down $map->set("width", $image_width); $map->set("height", $image_height); // flip off all layers on the map for ($i=0; $i < $map->numlayers; $i++) { $layer = $map->getLayer($i); $layer->set("status", MS_OFF); } // flip on those annotation layers we turned off earlier for ($i=0; $i < count($labels); $i++) { $labels[$i]->set("status", MS_ON); } // turn the scalebar back on if ($scalebar_present) { $scalebar->set("status", MS_EMBED); } // draw our image again, this time with just the annotations $label_image = $map->draw(); $label_url = $label_image->saveWebImage('MS_PNG', 1, 1, 0); // merge the text from our new image over the old one $old = imagecreatefrompng($root_directory . $label_url); imagecopyresampled($new, $old, 0, 0, 0, 0, $image_width, $image_height, $image_width, $image_height); // change our filename extention from .png to .jpg $image_url = substr($image_url, 0, -3) .

One other issue that I forgot about is that for labels outlines are fixed at 1 pixel. When that gets scaled back down, it mostly disappears. This looks like a good way to deal with that. And let the builtin text-drawing functions handle text antialiasing. Yet, I found that the scaled antialiasing method looked better even for text. I guess I'm used to high-end graphics antialiasing like is done in Illustrator and Photoshop. Freetype falls a little short of that, but is still pretty good. As for scaling a normal-size mapfile up, when I first started working on this method, that's what I started with (manually, not programmatically), but after fine-tuning a scaled mapfile, found that odd number in many cases gave better resampled output (ie a 1-pixel line might look better, in some cases, as 3-pixels scaled up at 2x instead of 2-pixels). Also, it doesn't look like it deals with scaling pattern fills or point symbols based on images. Or it may (just a quick skim of the code), but scale an image up, then back down antialiased and it'll look odd. But I'm sure this will work well for many. And you don't have to worry about scaling incoming image coordinates to the scaled mapfile. Or a manual scalebar overlay. With a little tuning, this function could be really nice. Eventually, with tuning my mapscript code as I have time, I'll probably have something similar (I don't know if I'll have a chance to test your function).

MapServer Tutorial:
Example 1.9

The map above was created in "map" mode. It is a static map.

This dynamic map is being generated in "browse" mode. Click on any point in the map and see what happens.

Both of these maps use the same mapfile definitions. The difference is that the second map (the dynamically created one) relies on HTML form for interactivity. If you look at how this page is linked from the previous page, you'll see that it isn't the same as the previous examples. This page is what's called, in MapServer terms, an HTML template. You will learn more about HTML templates in section 2.

have a look at the "form" block within this page (right click on your browser and select "view source" or something similar):

  <!-- START OF MAPSERVER FORM -->
  <form name="mapserv" method="GET" action="/cgi-
bin/mapserv40">
     <!-- HIDDEN MAPSERVER CGI VARIABLES -->
     <input type="hidden" name="map"
value="[map]">
     <input type="hidden" name="imgext"
value="[mapext]">
     <input type="hidden" name="imgxy" value="199.5
149.5">
     <input type="hidden" name="zoom"
value="1">
     <input type="hidden" name="mode"
value="browse">

     <div align="center">
          <table border="1" cellpadding="0"
cellspacing="0">
             <tr><td>
           <!-- THE INTERACTIVE, DYNAMICALLY CREATED MAP --
           <input type="image" name="img"
src="[ img ]" width="400"
height="300">
        </td></tr>
     </table>
     </div>
  </form>

This block executes the MapServer CGI program ("/cgi- bin/mapserv40") each time a user clicks on the map. The map is actually another form "input", represented here by the line: 

<input type="image" name="img"
src="[img]" width="400"
height="300">
The items in square brackets ([map], [mapext], and [img]) are what's known as MapServer tags--these are MapServer CGI variables and they get replaced by the MapServer CGI program when it reloads. The tag [map] is a placeholder for the mapfile path so it's replaced with "[map]" when MapServer runs. The tag [mapext] is replaced with the current map extent, "[mapext]", and the [img] tag is replaced with the path to the image the MapServer CGI program creates, "[img]".

The hidden variable "mode" with the value "browse" tells the CGI program that it needs to create and dump an image in the "tmp" directory. This image is then referenced as [img] and this is what you see on your browser.

Now, have a look at the mapfile:

There's really only one thing that's been added to the mapfile:

TEMPLATE 'example1-9.html'
This tells MapServer to use the page "example1-9.html" as a template file. MapServer will process this file and replace the tags it encounters before sending it to the web browser. This is how the next two sections in this tutorial works.

This marks the end of Section 1. I hope you leave this section with enough knowledge on how things are set in a MapServer MapFile. I can't stress enough the importance of keeping the MapServer MapFile Reference open as you create your own mapfile and application. Without it, I wouldn't have gone very far with this tutorial.. For a hierarchical view of the mapfile objects and keywords, please have a look at the reference page from Earth Data Analysis Center (EDAC) at the University of New Mexico.

Anyway, now I really appreciate efforts made for a preconfigured product with all needed components working inside... As already said, I use MS4W for Windows, version 1.0.3, and it works with no problems if one doesn't need a too much custom tool; problems start when you decide to make this product a little more sharpen. For example, a) I need to work with a custom legend different from which generated by traditional behaviour. For every map layer, or only for specific ones, I need to use "static" small gif images rather than ones automatically generated by MapServer so to produce a final Map page with a specific graphic layers legend rather than one based on "generic" Esri/ArcView symbols set. Furthermore I need to show or to hide different layers by group with a legend that gives me capacity to select or deselect both entire group or, inside it, every single layer. In "MapServer HTML Legend HOWTO" document I was not able to find a valid help: this document describes many things but it doesn't pratically say which files to modify but assumes only a certain ability to set MapServer templates. This opens next question, that is b) how does really templates work? Problem is every time I try to modify layout of final map including custom components (like buttons, links), or to change manually original layout or to translate contents in another languate than english, GMapFactory restores original template. Searching in published documentation I have found exhaustive references on how to set a template mapfile (.map), but not where MapLab stores GMapFactory settings; I think this is a crucial question because from GMapFactory depends layout definition of final map application and it makes possible to specify which mapping interface components to include or exclude... Certainly a great work has been done both in terms of programming both in making of detailed documentation but what I think is still weak is absence of a comprehensive description of entire working process of Mapserver and relative MapLab applications.

The above needs more explanation. To turn off labelling, set both the labelmin/max scale values to zero. In php/mapscript, I use code like this: $layerObj->set("labelminscale", 0); $layerObj->set("labelmaxscale", 0); . By not specifying LABELMIN/MAXSCALE in your map file, you will get labels. But to turn on labeling from php, I think (never had to turn them back on) you can set the labelmin/max scale values to bracket the $mapObj->scale. So if your map scale ($mapObj->scale) is 20000, then do something like this: $layerObj->set("labelminscale", 0); $layerObj->set("labelmaxscale", 100000000); This is the only way I know. If there's another way, please let me know.

Don't forget to include the trailing slashes. You'll notice that the IMAGEPATH points to your local directory while the IMAGEPATH points to the Apache Alias directory (or virtual directory in IIS parlance). MapServer dumps the output map to the IMAGEPATH and uses IMAGEURL to reference it for HTML template output. If you ran example 1.9 correctly, you will noticec that the "[img]" tag in the HTML template has been replaced with "/ms_tmp/". Lastly, note that you no longer call example 1.9 as http://localhost/tutorial/example1-9.html (this is probably what you did). Instead you pass example1-9.html to the MapServer CGI program by calling http://localhost/cgi-bin/mapserv50?map=/ms4w/apps/tutorial/example1-9.map. Example1-9.html is no longer a plain web page but a MapServer HTML template.

I am no PostGIS expert, but I had a similar problem recently. It seems that Postgresql uses different query optimization routines for the two types of queries. I solved my problem (with help from a stray comment on postGIS's site) by changing this parameter in postgresql.conf: random_page_cost = 2 (It was 4). This made it use the GIST index, where it was doing a full table scan. You can tell which one it's using by running your two queries with EXPLAIN ANALYZE before them. I would bet that one uses the index and the other doesn't.

Nuno, I believe there is a utility for splitting big files into tiles using GDAL floating around somewhere, but I didn't write it and don't really know much about it. However, it isn't too hard to write a script to call gdalwarp or gdal_translate to split a big file into tiles, while potentially resampling and/or reprojecting. http://www.gdal.org/ Check the gdalwarp and gdal_translate utliity pages.

I don`t know if is your case but I believe that this hints can help you. Here the client defined this data query: "the_geom from (SELECT regiao.the_geom AS the_geom, fundo.no_programa AS no_programa, fundo.nu_ano AS ano, fundo.vl_pago AS vl_pago FROM regiao inner join fundo on regiao.co_ibge = fundo.co_ibge and no_programa = 'PAB FIXO' and fundo.nu_ano = 2004 and regiao.co_ibge <= 150000 and regiao.co_ibge >= 140000) as pab_fixo using unique regiao.oid using srid=4291" But this query needed 55s to finish, and when I used the psql to run the asbinary query the results appear in 3s. The problem was with the UNIQUE parameter. The right data definition was: the_geom from (SELECT regiao.the_geom AS the_geom, regiao.oid as oid, fundo.no_programa AS no_programa, fundo.nu_ano AS ano, fundo.vl_pago AS vl_pago FROM regiao inner join fundo on regiao.co_ibge = fundo.co_ibge and no_programa = 'PAB FIXO' and fundo.nu_ano = 2004 and regiao.co_ibge <= 150000 and regiao.co_ibge >=140000) as pab_fixo using unique oid using srid=4291.

I expect things to get better when both Mapserver and ArcGIS will implement GML 3 level 0 profile, and the WMS spec will adopt that as the "standard" for GetFeatureInfo (or at least most WMS services will support this).

Let's back up a bit. Make the simplest possible mapscript application, and then run the web app under your debugger to find out what the problem actually is. If you can't debug your website, perhaps try with some sort of lightweight multithreading HTTP server. The .NET platform must have something like this. That said, now I am going to take a wild swing :) Any chance that you've overlooked building in the win32 thread support from mapthread.c? It's off by default in MapServer's windows makefile and never really mentioned in any of the win32 installation docs.

We went the other way, from a pre-tiled proprietary map image server to using pretty plain vanilla MapServer maps. It all depends on the application. What I'll call "TerraServer-style" tiled images (since they're the first implementation I know of, in 1998) are fast, and they provide good incremental drawing feedback - you know something's happening because you see the image appear in pieces. To get that, you give up arbitrary zoom scales (they're all precomputed) and you give up the ability to center the map on any point. DHTML has fixed the latter problem at the cost of some wasted bandwidth, since you're downloading images you don't display and may never display. The precomputed tiles also create a data management problem, since you need to reprocess the imagery when you get updates, and that can be just a bit tricky. Depending on your update frequency and size, this may not be an issue. Google's approach also wastes a lot of bandwidth downloading data that's never used. I do not know if that is related to the fact that I've been getting lots of broken-link images from Google's "satellite" imagery. You also don't see any UI on Google to turn those various data layers on and off, right? Sure, that could be done the same way, but you need to balance the precomputing overhead with the degree of user control over the map rendering. If you're going to give the user many options for controlling the map display, and do that with a large geographic area, it might not be worth it. As in most things in life, there are tradeoffs.

I jumped right in when the config option was made official/working (instead of being disabled forever). And on OS X, it's a plus, since the Apple-supplied PHP is an Apache module. Tho, I go and make my own PHP anyways to add other features... So far I haven't had any troubles with PHP-MapScript for PHP as an Apache module. Now that I have this distribution, and when I get enough feedback on how it's working, I _may_ make another for PHP as CGI, tho that would mean making an extra PHP installer also. ----- William Kyngesburye Mapping Specialists Don't Panic -------------- next part -------------- A non-text attachment was scrubbed...

This is because PHP MapScript objects are just PHP wrappers on top of the MapServer C structures, and when you set the variables explicitly using $point->x=1; then the value in the PHP wrapper is set, but the value is not propagated to the lower-level object inside MapServer because there was no way in PHP 4 to trap a change to an object member variable. In PHP5 this has been fixed, it will be possible to have callbacks (internally) to catch the change to the member variables and we'll be able to get rid of the set() methods... but this has not been implemented yet for PHP MapScript.

GRASS (with some notable help from GDAL) also provides great tools for tiling and resampling in a graphic (visual) environment, and also supports scripting.

So far it's been tested on a few clean Mac OS X systems (10.3.8). A few things I can think of- - when you installed my mapserver package, you also installed my PHP, gislibs, graphicslibs and postgres? My PHP probably isn't required - mapserver doesn't link directly to PHP - but if you use an alternate PHP, it should be installed in the same default location as in the PHP source: /usr/local/php. I think entropy's PHP does, but I haven't verified that yet. And the PHP extension folder should be 'extensions/no-debug-non-zts-20020429' in there. Even if you don't use postgres, both my PHP and MapServer are linked to it, as well as GDAL. You don't need to run postgres, just install it. - check the phpinfo() listing to make sure that php and mapscript are loading. I have an example in the PHP and MapServer readmes, but here's a recap - make a file testphp.php in your home/Sites folder with: Point Safari at localhost/~[your_user_name]/phptest.php and you should see all the gorey details of PHP's configuration, and in there should be a MapScript section. - Apple's httpd.conf is set up to use .php as the file extension for PHP files, not phtml. Try changing the example files to .php.

It is certainly true that something different is happening when using a cursor. Using pgAdmin, explain is reporting identical plans both with and without the cursor even though executions times are radically different. I managed to get response times reasonable by experimenting with several table index designs so this was certainly caused by a table scan. The unique oid clause had no measurable effect on the query time, but it's possible that the table scan time was so much larger that its effect was relatively small.

Inherent conservatism? Avoiding the extra thread locking overhead in cases where it isn't needed (it really serves no purpose in MapServer CGI). Johannes says: > Just another wild swing :-).

But you are right that all sorts of problems will occur if you don't do something like this. I would add that in a multithreaded windows situation it is also presumably important to use a multithreaded runtime library. I think this is accomplished by using /MT instead of /MD but I am not so familiar with this and whether it might interfere with the use of MSVCRT.DLL. Ideally we either need a savvy developer on windows who really cares about this multithreaded stuff and is willing to spend time to work out issues, and get them folded back into CVS. Or we need a client who cares enough to finanicially motivate a savvy developer to do all these things. MapServer works well on windows due to the efforts of Assefa and others, but the "dark corners" that don't affect Assefa or I can easily be poorly addressed. This certainly includes multi-threading and of course SWIG bindings like the C# ones.

James, I just took a quick look at this and it seems the SVG driver isn't yet built in by default. You need to manually add -DUSE_SVG in your FLAGS macro in the Makefile. I have also committed a change in maperror.c so that OUTPUT=SVG will be reported if SVG support is configured in. Assefa ... is there a reason SVG support isn't enabled by default?

That is, is the output image a rectangular piece of the original input image at the same size, or is it "zoomed in" or "zoomed out"? Unfortunately, scale ratios are meaningless for digital images without also specifying the output resolution in pixels per physical unit (inch, cm, etc.). It is very likely that the scale ratios of your source images refer to a different resolution than the default 72 pixels per inch that MapServer uses. Can you find out what the intended output resolution of your rasters is? For example, if I tell you that a raster is at 1/50000 scale, I am saying that one cm on the image equals 5 km on the ground. But that obviously depends on the physical resolution at which the image is viewed - if I am viewing it at 50 pixels per cm, then 50 pixels in the image equals 5 km on the gorund. But if I'm viewing it at 100 pixels per cm, then 100 pixels in the image equals 5 km on the ground. You need to know the intended viewing resolution in order to answer this question. If the rasters are scanned images of printed maps, this value would normally be the scan resolution. - Ed P.S.

The click-and-drag interface is so much nicer than having to wait for reloads. For all of our applications, losing arbitary zoom levels wouldn't be all that bad. In many ways, it would simplify things, as you'd only have to adjust your layers and displays for a preset number of zoom levels, without having to worry about how the maps look as they approach your various min/maxscales. For turning different map layers on and off, couldn't one just generate a different set of tiles for each layer, and create them with transparent backgrounds? I can't see why javascript couldn't overlay the different layers of tiles for a final image. That seems to be how Google is drawing their icons over the maps. Doing it that way would also allow for the toggling of layers without the need for a reload. Of course, the major hassle, as with all javascript applications, is supporting the wide variety of browsers out there. Last I checked Google maps only supported IE and Mozilla (not even Opera or Safari), though that may have changed by now. -Camden From assefa at DMSOLUTIONS.CA Thu Apr 7 10:39:39 2005 From: assefa at DMSOLUTIONS.CA (Yewondwossen Assefa) Date: Thu, 7 Apr 2005 13:39:39 -0400 Subject: Mapserver SVG output In-Reply-To: <931f8ea905040706575aecb71b@mail.gmail.com> Message-ID: The USE_SVG has been removed in the latest CVS.

We use shp2img to make the tiles and a DHTML front end pieces them together on the client side. Using 'PARTIALS FALSE' for all the labels, this generally works quite well. However, I have noticed two small problems that cause issues at the tile edges. First, 'FORCE TRUE' overrides 'PARTIALS FALSE', a fact we had to make a small patch to overcome. And second, when lines are drawn with a large symbol, the line stops drawing once the symbol center runs off the map, instead of once the symbol boundary completely leaves the map area. Oh and also there are sometimes strange vertical lines of various colors left at the tile edge. These small problems aside, kudos to the mapserver developers as we have been very happy with the results of using mapserver in this kind of environment! We now have three maps online: New York City, Washington DC and King County, WA. Here they are: http://www.propertyshark.com/maps/ http://www.propertyshark.com/maps/?map=dc http://www.propertyshark.com/maps/?map=kc Using a tiled approach certainly does limit your ability to let the user customize a map with selectable layers. But by superimposing layers of transparent image tiles, we are hoping to recreate some of this functionality. The primary difficulty will be in avoiding label collisions.

All you would have to do is write a script that has a double nested for loop to iterate over all your spatial data and define the bounding boxes for each tile, then ask mapserver to generate the tile and save it into your tree structure. Then do it again for each zoom scale you want. You can probably take the google javascript and then modify it to request tiles from your directory tree. You might want to write a very thin php script that converts tile requests in file requests, but maybe not. I would be interested in such a script if you want to develop it, in fact I might have a little time to collaborate on it. I don't thing the actual script is that hard, I'm not sure about what projection (lat-long? or otherwise) you would want/need to use so the tiles fit seamlessly together. It would also be interesting to know how much space and the number of files needed for each zoom level. -Steve W.

Thank you, although the javascript is the work of a collegue of mine. I do the mapfiles! Yes, we simply spawn shp2img on the same mapfile (with different EXTENT) for each 300x300 tile. Generating the whole map at once would surely not be feasible--I'm currently working on a map that is, at the highest zoom level, about one quarter of a terrapixel! However, we have considered making the tiles in larger pieces and then cutting them up. Still, this doesn't eliminate the problem but does reduces it. I've also noticed mapserver segfaults when you try to go above a certain image size--it would be nice if the memory structures were dynamically allocated. But perhaps that's a topic for the dev list.

However, we have So it sounds like you are generating all of the tiles statically and then just serving those up via javascript? Has anyone tried using mapserver to tile on the fly, i.e. use mapserver to generate image tiles at certain zoom levels based on feedback of the user searches. Then store tiles in a server cache. When users request a map, have the server check the server tile cache, before kicking off mapserver to create new tiles. While we are on the topic of mapserver, has anyone ever done work to write something like mod_mapserver for apache? It seems like the startup costs for a cgi based server are going to eat into speed over the long run. Remember, I'm still a newbie, so I could be completely off base here. Thanks!

With Google Maps using the Ajax concept (some info here - http://digitalsqueeze.com/drupal/node/3053) - has anyone tried/contemplated/dabbled at this approach using mapserver? Creating a map with mapserver can be fairly quick, reloading the page can take time, depending on your interface implementation - but if you only had to pass the map image back, that would be a huge step forward for the user experience.

When users request a map, have the >server check the server tile cache, before kicking off mapserver to >create new tiles. That's an interesting idea. It would get around the issue of updating tiles (which, for me, is the main disadvantage of a tiled system) if you incorporate some kind of verification of mapfile updates before grabbing a cached tile. On another note, a lot of the perceived extra speed of Google's maps comes from the client side caching of tiles outside the viewable map area. If you really pan quickly, this advantage goes away, but I suspect that most users don't pan much faster then the server can refresh. With MapServer, a similar solution might be to initially load a map some size larger than the viewable area, then have your javascript only request maps for the blank spaces as the user pans around. For any given pan you'll only need, at most, two dynamically sized tiles. Since these tiles will always be equal to or smaller than the viewable area, you aren't asking any more of mapserver than you normally would be, in terms of area anyway. You would be asking for two small maps instead of one bigger one, which might actually be slower. Even if it is though, the perception by the user will be increased speed as they pan around an area, because their client will likely be using cached tiles as they pan back over areas they've already seen. The hard part of such a system would be keeping track of these dynamically sized tiles cached on the client, and getting your labels right, but it doesn't seem impossible. The label issue might be solved by pulling a seperate "normal" labels-only mapserver layer after the base map loads. That way each pan reveals more map, and the user only has to wait for mapserver to create new labels.

We would like to give ArcGIS users access to the layers but it will not talk to the WMS service. I can get Jump to talk and of course MapServer/Chameleon also talks with the service and no problems. Is there a specific way in which you have to set up the map file? According to my research ArcGIS will not connect up to WMS servers that use any other projection except a Lat/Lon one. I re-projected some of our data using EPSG:4326 and setup a map file with only this projection and ArcGIS will still not talk. It reads the capabilities just fine, but after that it will not contact the server again. I have watched the Apache logs and I can see the capabilities request come through and then nothing. I have also tried other services like the DM Solutions demo here: http://www2.dmsolutions.ca/cgi-bin/mswms_gmap And it works fine with ArcGIS. Maybe one of the DM Solutions guys could point me in the right direction. :) Any help would be most appretiated and if there is a way of having the WMS also work with meter based projections (like Albers) at the same time would be great too.

The main thing that I utilize is never refreshing the whole page. I parse as much as possible using (extents, which layers are visible, etc) with Javascript and then change my map image using mapserver in cgi mode by constructing the url for the image with js. I also enable XMLHTTP requests to various other utilities such as a php geocoder that then returns information to the client that can be used to request a new image as well as display information about the found address on the client. In addition, I use PHP and Postgis with XMLHTTP requests to run my queries without the need to refresh the image. The approach that I have been using is to load all my layers as individual maps with transparent backgrounds. This is very handy since some of my layers (larger, complicated, Postgis layers) take much longer to load than other simple layers. Regardless of what layers the user has chosen to display, I preload all the maps to the client and then only display what the user has selected for display. This does two things for me. First, it gives near instantaneous interaction as the very simple layers come up right away with very little delay. Second, once all the layers have loaded, as long as you don't zoom or pan you can get instant results by turning layers on and off on the client.

Believe you me, I'd love to do this. But what prevents me from doing this and w/o the help of 10,000 CPUs to burn like google maps, is the fact that my underlying data changes constantly. I'm in the near real time ocean observation business, and I try to cache as much as I can. Considering that I go out around the clock fetching and aggregating ocean observations, an image that a user requests could be saved, yes, for caching purposes, but once the underlying data changes, that cached image is SOL. The caching that I do is hourly to keep the initial maps and the common extents performing somewhat snappily. But these hourly caches have to be refreshed whenever any new data comes in. While the google maps stuff is sexy, what would really blow me away would be a site that is that fast AND is also based on constantly changing underlying data.

The WMS, which is hosted locally, is a layer generated using OGR from a SQL-Server database. If I access the WMS layer using mapserver directly, the symbols are returned properly. I'm using an ESRI TT font to supply the symbol, with a definition in the fonts.txt file and the symbols.sym file. The problem is when I load the layer through my chameleon application. The SLD filters the points properly, and the symbol color is correct, but the symbol itself defaults to a filled square. Any ideas?

The problem is that I can't seem to find any way to query on different attributes while using a regular expression as follows. $qitem='att1' $qstring=('[att1]' = '/^[Tt].*/' or '[att2]'='test2') I have not been able to make the above work by using any of the following and many other combinations. $qstring=('[att1]' = /^[Tt].*/ or '[att2]'='test2') with error msDBFGetItemIndex(): Item 'Tt' not found. $qstring=('[att1]' = '/^[Tt].*/' or '[att2]'='test2') with error msDBFGetItemIndex(): Item 'Tt' not found. $qstring=('[att1]' = '/^[Tt].*/') with error msDBFGetItemIndex(): Item 'Tt' not found. $qstring=('[name]' = /^T.*/) with error msEvalExpression: Failed to parse expression msyyparse(): syntax error. The last one seems like the expression is trying to be parsed. This wouldn't be necessary if there was a way to intersect querys or to do a sub query on results from a prior query.

Related to the zooming in STEPS vs completely dynamically, you could have two modes of operation, one "SPEED" mode that would use the STEPped zooming, and a second "ACCURACY" mode for getting exactly what you want. The server could still use the same tiling system on the server, but handle the between step interpolation of the data dynamically from the tiles or even from the Data sources themselves in a typical Mapserver install. If you add in an additional step of tiling a larger image generation into smaller tiles, you would get around the label problem, this would all be serverside trickery, but it would help out with tile writing and keeping track of which tiles are how old and whether they might have label artifacts along the edges or not (the server would generate new edge tiles if the edge were crossed in subsequent requests for example). bobb > >Jeremy > > > From superbla3000 at GMX.NET Thu Apr 7 13:18:58 2005 From: superbla3000 at GMX.NET (joerg pfeiffer) Date: Thu, 7 Apr 2005 22:18:58 +0200 Subject: gazetter files Message-ID: hello, I would like to use a gazetter file of the format Zwolfling P PPL 48.6166 13.5833 ....

Don, Looking at the pattern of seeks and reads, it would seem that stuff is getting read in 8K chunks which I would presume is being done by the C stdio library in response to lots of little reads in mapserver. Similarly it would seem that the low level seeks are being generated by the stdio library. In other words, I don't think this is under the control of MapServer. I'm not sure why things are so much slower on your Solaris box. As SteveW mentions, you didn't have the qix before but you say it didn't help. The qix should ensure that only (roughly) the right data is getting read. Are you essentially rendering everything? Have you verified that it is really the IO that is slowing you down?

I'm not sure what your file structure is, but you might want to run something like: find /path/to/data -name "*.shp" -exec shptree {} \; just to make sure you have them all in place, They should not slow anything down. Also I did not catch that these are calls to open/read/lseek which are the low level system IO calls and not fopen/fread/fseek which are the calls the shapelib uses, so I would concur that this is the underlying Solaris IO system you are tracing which is outside the control of mapsever. This is not to say that this might not also be your problem, but I would investigate other mapserver config issues first. Do you have this "same" setup still on linux, can you compare the directory trees, the mapfile, are you really comparing apples to apples. Also, how large are the shapefile files that you are reading? How many entities? Are really rendering all entities in them? -Steve W.

Haven't really tested php extensively, but some simple tests work ok. I have configured Mapserver with the following command. ./configure --with-proj --with-ogr --with-gdal --with-jpeg --with-png --with-tiff --with-postgis --with-wfs --with-wcs --with-wms --with-wfsclient --with-wmsclient --with-php=/usr/src/php-4.3.10/ then ran make and copied the 'mapserv' executable into the cgi-bin directory. When attempting to access a mapfile using the cgi-script directly http://domainname.com/cgi-bin/mapserv?map=/home/www/map1.map&mode=map I am returned '500 Internal Server error'. The logfile contains 'Premature end of script headers: /usr/local/apache/cgi-bin/mapserv' If I re-run configure and remove the --with-php=/usr/src/php-4.3.10/ directive and recompile, the map displays fine. I had originally compiled PHP as a DSO, but couldnt get mapserver to work this way either, so reverted to compiling php into apache directly. Any ideas?

Here is how I did it for using 4.0.1 # required by gd-2 sudo apt-get install libpng3 libpng3-dev sudo apt-get install libjpeg62 libjpeg62-dev # required by php4 sudo apt-get install libmysqlclient10-dev # required by owt sudo apt-get install libttf-dev libttf2 # For curl-7.11.0.tar.gz ( cd curl-7.11.0 echo '--------------------- curl-7.11.0 ------------------------' ./configure --prefix=/opt/mapserver/ make sudo make install ) sleep 5 # For freetype-2.1.5.tar.gz ( cd freetype-2.1.5 echo '-------------------- freetype-2.1.5 ----------------------' ./configure --prefix=/opt/mapserver/ make sudo make install ) sleep 5 # For gd-2.0.21.tar.gz ( cd gd-2.0.21 echo '---------------------- gd-2.0.21 --------------------------' ./configure --prefix=/opt/mapserver/ --with-freetype=/opt/mapserver/ make sudo make install ) sleep 5 # For gdal-1.1.9.tar.gz ( cd gdal-1.1.9 echo '--------------------- gdal-1.1.9 --------------------------' ./configure --prefix=/opt/mapserver/ --with-ogr --without-gif make sudo make install ) sleep 5 # For proj-4.4.7.tar.gz ( cd proj-4.4.7 echo '--------------------- proj-4.4.7 --------------------------' ./configure --prefix=/opt/mapserver/ make sudo make install ) sleep 5 # For expat-1.95.7.tar.gz ( cd expat-1.95.7 echo '-------------------- expat-1.95.7 -------------------------' ./configure --prefix=/opt/mapserver/ make sudo make install ) sleep 5 # For php-4.3.4.tar.gz ( cd mapserver-4.0.1 ./configure \ --with-httpd=/usr/sbin/apache \ --with-proj=/opt/mapserver \ --with-wmsclient \ --with-gd=/opt/mapserver \ --with-freetype=/opt/mapserver \ --with-gdal \ --with-ogr=/opt/mapserver/bin/gdal-config \ --with-php=../php-4.3.4 \ --without-tiff \ --enable-runpath \ --without-xpm \ --with-curl-config=/opt/mapserver/bin/curl-config make sudo mkdir /opt/mapserver/cgi-bin sudo cp mapserv scalebar legend /opt/mapserver/cgi-bin/ sudo cp mapscript/php3/php_mapscript.so /opt/mapserver/php4/extensions/ ) After this you need config apache with a block that uses the /opt/mapserver/cgi-bin/php version you built above for any php scripts and then keep all you php/mapscript scripts in this directory tree. Any php scripts out side the directory tree will use system version of php whatever that is. Hope this helps, -Steve W.

For example, if I tell you that a raster is at 1/50000 scale, I am saying that one cm on the image equals 5 km on the ground. But that obviously depends on the physical resolution at which the image is viewed - if I am viewing it at 50 pixels per cm, then 50 pixels in the image equals 5 km on the gorund. But if I'm viewing it at 100 pixels per cm, then 100 pixels in the image equals 5 km on the ground. You need to know the intended viewing resolution in order to answer this question. > > If the rasters are scanned images of printed maps, this value would normally be the scan resolution. > > - Ed Great, I received the information about the "intented viewing resolution". It was 32 points per cm, giving 81.28 dpi ! I've set the RESOLUTION parameter to 81.28 and it renders perfectly when using scale near the raster scale !

WE are not as fast because WE do not have 10,000 CPUs and level 1 fibreoptix internet nodes - thats all. Warning: PointOfView! If you think this is too off topic just tell me i'll quit it. Maybe we should also discuss this topic the other way round. Why not tell Google to rather stick to standards and let them 10,000 CPUs burn MapServer images? :-) Just because Google is a bigshot in the web does not *have to* mean that they are stupid - ahhm - wont listen to you experts. I bet that Google could operate a bunch of MapServers just as fast as those cached and tiled googlemaps we see now. And they would not be restricted to scale levels. I also repeat myself when i say that google maps only *seem* to be faster psychologically - they definitely are not faster *physically*. Performance at this stage is eaten up by opening and closing requests in the browser. Believe me, we have this problem every day when we try to loose weight with our client interfaces. The WMS images are definitely *not* the bottleneck. Googlemaps is a nice experiment but we KNOW that it is no good in the long run. Have a look at the scales and resolution satellite image they offer, this is a minuscule fraction of all satellite and ortho images available world wide - as WMS. And googlemaps will never ever be able to be integrated with any of those datasets. What a waste of energy. Hey - we are falling back into medieval raster tile viewers - i thought that we had overcome those times long ago. Somebody should really point this out to Google, else they might make a big mess of the standardized infrastructures that are slowly emerging all over the place. We should not let this happen. We have MapServer installations running with TBs of aerial photography data which never take longer than a few millisec to answer. You simply cannot make this any faster (i know, i know Frank and Steve and Daniel and Yasseffa and all you other cracks *do* get it faster every now and then...).

We have conducted on and off analysis of user interactions on heavily frequented map interfaces. Most people never pan a map anywhere when they are initially navigated to the correct section of the map they want to see. So what i think is lot more important ragarding googlemaps is the way they geocode and reverse geolocate. Imagine Google implementing a standardized WFS / gazetteer. That would be really great indeed, interoperable and everything. Google databases already contains loads of geographically relevant data and information - it has simply not been tapped yet. > For all of our applications, losing arbitary zoom levels wouldn't be > all that bad.

That might be true for data that does not change often. It might also be true for data that you want to see in one coordinate system only. And for data that you do not want to overlay intersect and visualize with data from another source. Think interoperable and what googlemaps has shown us up to now is not worth a penny. > For turning different map layers on and off, couldn't one just > generate a different set of tiles for each layer, and create them with > transparent backgrounds?

For example, if I tell you that a raster is at 1/50000 scale, I am saying that one cm on the image equals 5 km on the ground. But that obviously depends on the physical resolution at which the image is viewed - if I am viewing it at 50 pixels per cm, then 50 pixels in the image equals 5 km on the gorund.

It's worse than that. Solaris, by default, uses an 8k-inode. Linux used to use 1k or 2k inodes in e2fs, but I think they went to 32k inodes as of late (been a long, long time). This would easily account for the increased read-time under Linux. trussing (and subsequently dtracing) mapserver on my own Solaris box shows the exact same behavior, which is something I'd been meaning to track down for awhile now, but just hadn't had the impoetus to do until now. :) The read/seek limit is going to be a factor of the disk block size in this case, so the solution here is to crank up your inode size. The downside to using a larger inode size is that smaller files may end up taking up MORE disk space, but not necessarily (this really becomes a discussion of Unix file storage techniques, which is beyond the scope of me, or this list, I'm afraid :) Cheers! -Matt. -- _ Matthew Holger (mholger at optera.net) || ASCII ribbon campaign ( ) Unix Systems Administrator || against HTML Email X http://www.Optera.NET/ :: m:651.271.3248 || http://arc.pasp.de/ / \ From pscott at UWC.AC.ZA Fri Apr 8 07:49:56 2005 From: pscott at UWC.AC.ZA (Paul Scott) Date: Fri, 8 Apr 2005 15:49:56 +0100 Subject: make error Message-ID: Hey list, I am trying to compile Mapserver-4.4.1 on RH9 with configure options of: /configure --without-tiff --without-eppl --with-threads --with-geos --with-proj --with-gdal=/usr/local/bin/gdal-config --with-ogr --with-php=/home/paul/mapserver/php-4.3.11 --with-gd=/usr/local --with-freetype=/usr/bin --without-pdf --with-ming --with-wmsclient --with-wfs --with-wfsclient --with-postgis=/usr/local/pgsql/bin/pg_config but it fails with: gcc -c -O2 -fPIC -Wall -DIGNORE_MISSING_DATA -DNEED_STRLCAT -DUSE_PROJ -DUSE_PROJ_API_H -DUSE_WMS_SVR -DUSE_WMS_LYR -DUSE_WFS_SVR -DUSE_WFS_LYR -DUSE_MING_FLASH -DUSE_GD_GIF -DUSE_GD_PNG -DUSE_GD_WBMP -DUSE_GD_FT -DGD_HAS_GDIMAGEGIFPTR -DGD_HAS_GETBITMAPFONTS -DUSE_OGR -DUSE_GDAL -DUSE_GEOS -DUSE_ICONV -DUSE_POSTGIS -DUSE_THREAD -I/usr/local/include -I/usr/local/include -I/usr/local/pgsql/include -I/usr/local/include -I maptemplate.c -o maptemplate.o gcc: no input files make: *** [maptemplate.o] Error 1 I have tried running ldconfig (in case it was missing a lib), but nothing seems to help.

I upgraded to version 4.4 and replaced all wms_ and wfs_ parameters with ows_. Now I have some trouble with the layer groups and group titles and most of my layers are assigned to a group (such as 'reference layer' or 'satellite imagery'). Apparently, wfs doesn't read group titles, and simply ignores these parameters, so no problem here. To the contrary, wms did search for group titles before and still does, but something must have changed. According to the HOW TO document, you can now specifiy wms_group_title and wms_group_abstract (in the web object?) and wms_layer_group in the layer object - all is optional. It also says that all group names should be preceded by a forward slash, and the group name should not be used at the same time. Actually, I would like to preserve the group parameter, since I am grouping the layers according to this name...

This will provide a 1 level deep layer nesting, e.g.: mygroup title of mygroup mylayer title of mylayer These groups can also be requested, ie they have a name. 2) if you need deeper nesting (more than 1 level deep), you can use wms_layer_group instead of GROUP "wms_layer_group" "/Hydrography of the Netherlands/Rivers" This will create: Hydrography of the Netherlands Rivers mylayer title of mylayer These groups cannot be requested, ie they only have a title and are merely intended for applying a nesting/structure to your data, eg when a WMS service is added in a treeview.

I upgraded to version 4.4 and replaced all wms_ and wfs_ parameters with ows_. Now I have some trouble with the layer groups and group titles and most of my layers are assigned to a group (such as 'reference layer' or 'satellite imagery'). Apparently, wfs doesn't read group titles, and simply ignores these parameters, so no problem here. To the contrary, wms did search for group titles before and still does, but something must have changed. According to the HOW TO document, you can now specifiy wms_group_title and wms_group_abstract (in the web object?) and wms_layer_group in the layer object - all is optional. It also says that all group names should be preceded by a forward slash, and the group name should not be used at the same time. Actually, I would like to preserve the group parameter, since I am grouping the layers according to this name... Whatever I do, the wms GetCapability request always returns layer name and group name of the same layer as if they were two different layer objects!

I am all for interoperability and all, but I argue that the vast majority of GIS types looking to implement a Mapserver/IMS site are not interested in mapping the world or integrating a bunch of disparate data sources. They are GIS managers and technicians at the Municipal and Territorial (State, Province, whatever) level interested in providing their constituents access to public information. Providing these potential customers/developers with the ability to automatically generate tiled maps that can be served quickly is definitely a worthwhile effort. Getting someone hooked on Mapserver and Open Source solutions by giving them what they want/need is a good thing. Once people see the great things possible with standards like WFS and the creative juices start flowing, maybe a few of them will make the leap to a more dynamic mapserver interface... But you've got to get them in the door first.

My company is working on a mapserver based application to display data from agents in the field(GPS located) on a map, this works fine with mapserver. Management wants street level maps displayed for all locations where we could possibly have agents. Right now our testing is in the US, so I just grabbed the Tiger data for a quick overview. Our initial pilot will include Western Europe(UK and France mainly) as well as the US. So I'm trying to find a good source of data for these regions that interoperates well with mapserver(shapefiles) or allows us to query them using WMS. Management likes Mapquest, however all of their stuff appears to be oriented towards proprietary APIs which would require significant time to implement. I know that this type of data will not be inexpensive but Navteq was a bit over what we wanted to pay.

These work just the way that I expected and wanted. So when I was asked to add a layer that shows routes based upon the name of sales people I thought no problem. I have the the name in a MySQL table and the routes as points in another table so I thought all I would have to do would be to add a little PHP code. Make a list box that is populated from the table in the database. Well it works when I display just the template, however when I try to to display a map the list box is not populated from the database. In fact it does not even seem like the PHP code is connecting to the database at all. After about a week of trouble shooting I eliminated all parts of the template as being the culprit. The only thing left that I can think of is that somehow that by calling the mapserver cgi it is causing the PHP code not to connect to the database and populate the list box. I know the jbox template works with a map and the list box works in the template but when I try to get all 3 to work together the list box fails. Has anyone come across anything like this before or have any suggestions? Oh yes, I'm not using any php/mapscript just straight php.

I The mapserver CGI can not call or run PHP on that page. When you make a request to a web server it passes a request for dynamic content on to the appropriate application, mapserver CGI OR PHP (or ASP, or Python, or whatever). That application does its thing and passes a page back to the web server, which in turn passes the page back to you. But mapserver can not call the PHP process, or any other process on the server. Point is, only one server side process can be called per page. (jBox is a client side process). If you can convert your MySQL data into a shape file that would probably be easiset. Mapserver has some support for connecting to MySQL, but I have not experience with it (search the list archives). Or you could convert your app to Mapscript.

Since the rest of the application is already using PHP, it seems like the way to go for your application. I have used the Zend IDE for PHP, but end up usually working in a text editor. I can recommend the PHP Cookbook by O'Reilly. I had not seen that Mapserver book yet, it is to be published in June 2005 I see. There is also gonna be an O'Reilly book on Mapserver and Open Source GIS in general, written by Tyler Mitchell, which will include Mapscript examples in Python, Perl, PHP and Java. An excellent resource for PHP/Mapscript will be downloading Chameleon from DM Solutions, you can download that from maptools.org. Will provide you with lots and lots of PHP/Mapscript examples in their code. WMS performs okay, especially if most of your data is coming from the same service. If you are gonna combine several services, except a noticeable drop in performance, but it is still doable for sure. Hope this helps.

The editor in MX 2004 is much improved over previous versions. If you're comfortable and more productive with a programmer's editor (I'm on Mac OS X and code in BBEdit), then you can split the drag-and-drop editing and the text editing between Dreamweaver and your preferred editor. Setting your external editor is a Preference in Dreamweaver. Documentation: The online help docs at http://www.php.net is excellent, and http://pear.php.net/manual/ is good too. ----- James Cradock, jcradock at me3.com From bill at BINKO.NET Sun Apr 10 10:44:54 2005 From: bill at BINKO.NET (Bill Binko) Date: Sun, 10 Apr 2005 13:44:54 -0400 Subject: =?utf-8?b?W1VNTl9NQVBTRVJWRVItVVNFUlNd?= mapserver, jbox and php (but not mapscript) In-Reply-To: Message-ID: On Sat, 9 Apr 2005, Richard Greenwood wrote: > kallwn ICIRCUS.NET> writes: > > > The only thing left that I can think > > of is that somehow that by calling the mapserver cgi it is causing the > > PHP code not to connect to the database and populate the list box.

Another easy solution is to simply "double-pump" the request. That is, your template file does nothing but set some variables and do a refresh to your PHP page. I have used that well. Lets say you need to send an ID (parcel ID n my case) to a dynamic PHP script. You setup something like 'parcel_id' to be the variable you want and just write a template that does the refresh:

If you are not automatically redirected, you can access Your Information by clicking on this link.

That way, you can do all your logic in PHP (in the myPhpScript.php page). Of course, if you're sending lots of information, that URL= parameter can get pretty ugly. You also want to make sure you have the "0; " before the url since that the silly format. The 0 says how long to wait. I also always include the link in the BODY section so that people who diable meta-refreshes have a way to get at your information. Hope this helps.

I do not see this a FC3 specific problem, I think it happens whenever PHP is compiled with the bundled GD library. The php_ prefix to GD function names was introduced to the bundled GD package in PHP last summer in order to prevent name space conflicts with other apache modules that use GD, such as perl. Now if PHP uses the bundled GD, mapserver 4.4.1 will still compile if I point to external GD libs, but compilation of PHP_mapscript will fail. On the other hand, if I try to trick mapscript to compile against PHP's bundled GD then I get segfault at mapscript dl-time. Could something similar to --with-php-regex-dir in mapserver configure scripts solve this? Of course recompiling PHP with external GD is an option, but then I am out out sync with FC3 update packages, which means increased maintenance burden. > On Apr 9, 2005 9:21 PM, Morten Hulden wrote: > >>Giridhar Manepalli wrote: >> >>>Currently, I am trying to install on Fedora Core 3, with php-4.3.11. > I built it as a DSO similar to the working model. >> >>If you get mapscript 4.4.1 to work on plain Fedora Core 3 I am >>interested to know how you get around the fact that FC3 comes with a PHP >>that has a bundled GD version where function names have a php_ prefix >>that mapscript will not recognize. >> >>Even if compile succeeds after some tricks, dl() segfaults because of >>undefined symbols. >> >>Recompiling PHP to use external GD seemed to be the only option last I >>tried, but that was a while ago... >> >>rgds >> From woodbri at SWOODBRIDGE.COM Sun Apr 10 19:20:38 2005 From: woodbri at SWOODBRIDGE.COM (Stephen Woodbridge) Date: Sun, 10 Apr 2005 22:20:38 -0400 Subject: zooooooom In-Reply-To: <42599E53.90406@maxnet.co.nz> Message-ID: Matthew, This might be your problem http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=306 Read the bug, it gives work a rounds. -Steve W.

My project has large shp files (2 are greater than 1 gig). My obvious solution to the speed problem was to tile the shp files. After (finally) getting shp2tile compiled, I tried several different option combinations and got what were to me unexpected results. What I expected was some kind of world file for each tile and then use shptree to index the files. What I got of course was a series of shp files. My questions are as follows: 1. How do I figure out how many rows and colums to use in the shp2tile program? The shp file contains approx 54000 shapes. 2. If i use the quadtree option, how do I know what value to use? 3. Is there a way to create an index on the shp files that are produced with the shp2tile program, so that I do not have to create a layer for each shp file? 4. What else am I missing?

Joao, As the configure message suggests, I believe you need to download a recent version of gd, build and install it, and the configure with something like "--with-gd=/usr/local".

I felt like having to blurt out my ideas because of two issues: 1. we (that is the several hundred people on this and many more lists) are experts for geodata software, both implementing and using it. We are not any less serious thinkers and the summed budget of the Open Source community should also not be underestimated. Its all bits and pieces but its lots of bits an pieces. Find out how many developers are behind google maps? That would really be interesting, i bet its less peopel than those furthering MapServer, GeoServer, PROJ4, GDAL, OGR, deegree, GEOS and all those other goodies we use every day without much thinking. So my message should have been: We do not have to hide ourselves behind "...well funded companies employing serious brain power." Maybe i should just stop preaching and thats it. :-) 2. We had a hard time trying to get people to stick to standards and i'd hate to see a reverssl of that process - although i strongly believe that this will not happen any more. Both points stated i fully agree that: We should definitely not ignore significant developments by large, well funded companies employing serious brain power. :-) Serving several million maps a day will be faster using predefined tiles. Conceded. Those maps have to be put together with some piece of software all the same. Why not get the Google map developers to join Open Source GIS dev instead of having them reinvent the wheel in a way we cant use. Google already has opened itself a little to the OS community (maybe because they are not that large at all). If those maps are created without following any open standards but some Google standards and become an integral part of our geo websphere then we will not get rid of them any more.

We are getting there!! But still, maps.google.com is all the rage. Since it's release, I would estimate 5 emails a week related to maps.google.com. It's easy. People can use it (for the most part). The point (to steal a quote from JF) is that we have done a fantastic job at pulling things apart; now if we can just do just as good a job at pulling things together.

The shp file contains approx 54000 shapes. There is no magic number. If you data is spread evenly over the area then you can expect row*col tile or about 54000/(row*col) in each tile.

I see your layer STATUS is set to ON. This really just means "potentially available", and it has to be turned on by an appropriate (hidden) form variable in the mapserv.exe context I believe. Try setting the STATUS to DEFAULT. If that works, then you need to read up on how layers are enabled and disabled in mapserver. If that doesn't help then the issue is something else...

Only solution sofar is to recompile PHP from sources and have it use an external GD library.

If you are most showing all your parcels most of the time then there is not value in having it tiled. One of the MOST important performance issues is to make sure all your *.shp files have a *.qix file. Try a different set of tiling parameters and test it again. Did you have *.qix on you original shapefile? If not go back to that and add one (shptree file.shp) and see how it performs untiled. -Steve Don Deskins wrote: > Bart and Steve, > > My shapefiles are showing up now... thanks! > > Now I have a time problem...

If you leave out all PROJECTION blocks, then all entities are presumed to have the same projection. If you only specify a PROJECTION for the output map, then all layers are presumed to use that same projection. If you specify two layers with different projections, then you also need to specify the PROJECTION you want for the output map image.

Is it the black edging that you want to get rid of? Or is the problem that the image area is saturated to white? Your MODIS image data is 16 bit. By default MapServer just reads the data into an 8bit buffer, converting all values over 255 to 255, and all values below 0 to 0. I imagine you will want to scale the values. If you read the RASTER HOWTO I think you will find that scaling is covered there. The quick approach is to add the following to your raster layer.

Jim, When accessing ODBC tables through VRT there is no attempt made to do spatial queries in a smart way. What happens is that all records in the ODBC tables are read, converted into features via the VRT file, and then those outside the spatial rectangle are discarded before returning the remaining features to MapServer. This is suitable for modest numbers of features, but does not scale to large number of features as you may be noteing. In particular it is not at all equivelent to using a spatial indexed RDBMS such as PostGIS or Oracle (with a spatial table). In theory I could modify the VRT driver in OGR to use a query restricting the X and Y columns based on the spatial query in a case like this, but these dual-constraint ranged based queries are often not all that efficiently handled by RDBMSes even with the columns indexed. However, if squeezing additional performance out of your current configuration is quite important to you we could talk about me adding such a features on contract. I would be willing to add such an optimization for $800 USD.

Hang on. The second is wrong. The two others seems to do the same thing.

This can result in quite large divergence in the case of long line segments. If you are using reprojection to turn straight lines into great circle arcs, you will need to subdivide the original lines in advance. There is no specific support for plotting great circles in mapserver.

It is version 1.141.2.1 of mapserv.c (calls msResetErrorList() after completing - or failing - an OWS request). > This build has worked > fine before on Win2000.

I will say that the build process is complex including the need to past the fastcgi client library (as noted in the wiki) and care must be taken to build with MSVCRT.DLL. I haven't tried with VC7, but I think that would be imprudent. I think the precompiled binaries for GD are fine as long as you build with VC6 and /MD.

I'm assuming you are using MapServer 4.4. First, of all, you should generally compare integer results from mapscript to mapscript.MS_SUCCESS (0) and mapscript.MS_FAILURE (1). Second, I think you really should be doing something like this: layerObj layer = mp.getLayerByName("layer"); ... layer.queryByAttributes(...); resultCacheObj results = layer.getResults(); if (results) { resultCacheMemberObj result = results.getResult(0); } Keep in mind that the extents of your 'mp' map are used to filter results. If you query by attributes for a feature outside the map extents, it will not be found. cheers, Sean -- Sean Gillies sgillies at frii dot com http://users.frii.com/sgillies From pauljame at GMAIL.COM Tue Apr 12 11:07:26 2005 From: pauljame at GMAIL.COM (Paul james) Date: Tue, 12 Apr 2005 15:07:26 -0300 Subject: queryByAttributes...

I found documentation in the wiki and in the source code in a file named mapimagemap.c. My php script used 2 map files. One map file was for rendering the image, which I copied and added outputformat statements for generating the imagemap: IMAGETYPE imagemap OUTPUTFORMAT NAME imagemap DRIVER imagemap FORMATOPTION "POLYHREF=#" FORMATOPTION "SYMBOLHREF=#" FORMATOPTION "SUPPRESS=YES" FORMATOPTION "MAPNAME=tulsamap" FORMATOPTION "POLYMOUSEOUT=return nd();" FORMATOPTION "POLYMOUSEOVER=return overlib('%s');" MIMETYPE "text/html" END Not sure if you can do this without scripting. My php script disabled unwanted layers and dumped the coordinates into the html stream: $imgM = $mapImg->draw(); echo "saveImage("", $mapImg); echo "\n"; This actually worked quite well. I had one problem, though. If the map was empty (no features within the map extents) the php session would crash with no error messages. See note submitted to list on April 1.

I compiled mapserver with fastcgi support, and the mapserv.fcgi process is started at Apache startup. However, there is no performance increase, even in PostGIS-heavy maps. Strangely, if I set Apache's LogLevel to info or debug, I get no diagnostic messages from the new mapserver. I was of the impression that fcgi would display debugging info, yes? (I used a test program from fastcgi.com, and it too displayed no debugging info even with LogLevel set to debug) Equally strangely, if I do lsof and grep for the mapserv's pid, I do see that the mapserver.fcgi is holding the socket file, and that the webserver is holding the socket file. But I see no indication that the mapserver.fcgi is doing anything else persistent, e.g. database connections. Should I see a few TCP connections attached to the server process? Should I see more than one mapserv.fcgi process spawned? Does the following httpd.conf paragraph look right, or am I missing something? (yes, there's a directory named fcgi where the sockets are stored) LoadModule fastcgi_module libexec/mod_fastcgi.so AddHandler fastcgi-script .fcgi FastCgiIpcDir fcgi FastCgiServer cgi-bin/mapserv.fcgi -flush -socket mapserver-fcgi.socket Any ideas as to where I should look to see a performance increase?

Gregor, MapServer normally has quite low "start up" costs, and for that reason it does not normally benefit much from FastCGI. Exceptions are the database connections with high overhead, such as Oracle, and SDE. It was specifically for these two datasources that FastCGI support was implemented. I would add that to convince MapServer to "hold open" a database connection you need to tell it to do so. This is accomplished by adding the following on layers for which you would like to preserve the database connection: PROCESSING "CLOSE_CONNECTION=DEFER" This works for SDE, Oracle and PostGIS, though it gives relatively little benefit for PostGIS since PostGIS has such a low connection overhead already. Actually, the CLOSE_CONNECTION=DEFER thing also works for OGR datasources, though how much benefit it gives for them varies greatly depending on how the format driver is implemented. In recent tests mapping directly from S-57 format (via OGR) FastCGI gave a substantial speed up, mainly because the S-57 data was all being parsed and held in OGRFeature format in RAM due to the deferred connection closing. This doesn't necessarily scale up to large amounts of data well. Eventually, I would like to also take advantage of deferred closing in FastCGI mode for GDAL rasters, but I haven't yet pursued that option.

Bummer. I think that the "new" location of the constants is awkward and that we should consider some changes to map.h that will return them to a better location.

When I remove the --with-php=/usr/include/php --with-php-regex-dir=/usr/src/php/php-5.0.4/regex parameters, I compile a mapserv executable capable of rendering PNG using shp2img. As mentioned above, when I include the mapscript build, the executable segfaults. I have been pulling my hair out for a couple days on this one (using 4.4.1). Any thoughts? I know the mapfile and perms, etc are correct as I can render images without the inclusion of mapscript. I read some threads with regard to GDAL and JPG/TIFF issues (I did try using the internal GDAL libs), but I don't think that is the issue...especially since if I pull the php, things compile.

Having said that, I now allow myself to include my .html file and .map file (both clipped to save some bandwidth). Note that I ended up using full paths, since nothing made this thing work. I use Windows. All my static maps work fine and it's just a path problem that I can't seem to figure out.

That did the trick. Thank you, Frank. For most of the map, the speedup is modest but measurable. For one particular view, though, it reduces the generation time from 15 seconds to <5 seconds. Mileage varies. What is the algorithm for keeping those DB connections persistent? Do they get closed automatically after a set period or number of connections? Do I need to worry about maxing out my DB's allowed connections? Say, the documentation on the PROCESSING keyword is rather sparse. What exactly does the CLOSE_CONNECTION=DEFER flag do in a non-fcgi environment? Does the data source stay open until the end of the mapserv.cgi execution, and save the overhead of opening/closing a data source that would be used in multiple layers? __________________________________ Do you Yahoo!?

Actually, you should use something like --with-gd=/usr when compiling PHP. Otherwise PHP gets compiled with it's bundled version of GD, and php_mapscript.so gets compiled with whatever version of GD is found at build time. If these versions don't match exactly, nasty things can happen. Substitute the real path where GD is installed instead of /usr, of course. To be really sure, use the same path when compiling Mapserver. If you have only one version of GD installed on your system, it shouldn't matter, but better safe than sorry. > I read some threads with regard to GDAL and JPG/TIFF issues (I did > try using the internal GDAL libs), but I don't think that is the > issue... especially since if I pull the php, things compile. This seems a likely indication of conflicting GD versions between PHP and Mapserver. -- Toomas From gerard_b_18 at HOTMAIL.COM Wed Apr 13 12:15:50 2005 From: gerard_b_18 at HOTMAIL.COM (gerard barrington) Date: Wed, 13 Apr 2005 16:45:50 -0230 Subject: shapefile polygon opens in arcgis but not mapserver In-Reply-To: Message-ID: An HTML attachment was scrubbed...

First, I have to make many assumptions as I don't know if you change any of the directory structure of the tutorial. I'm assuming you didn't and that you unzipped it under "/ms4w/apps". This would give you a directory "/ms4w/apps/tutorial" and everything will be set there save the Apache configuration. My second assumption is that you have created an "httpd_tutorial.conf" Apache config file in "/ms4w/httpd.d" and that this file contains something like: Alias /tutorial "/ms4w/apps/tutorial" AllowOverride None Options Indexes MultiViews Order allow,deny Allow from all If you haven't read the README_HTTPD.txt under /ms4w/httpd.d, you should do so. The last assumption I'll make is that you didn't change the MS4W temp directory so that it's still under /ms4w/tmp/ms_tmp. OK then, have a look at your IMAGEPATH and IMAGEURL parameters... Your IMAGEPATH should point to "/ms4w/tmp/ms_tmp/"--that's your local path. Your IMAGEURL then should point to "/ms_tmp/"--that's how it's referenced in an HTTP url (the Alias in Apache). These paths should be explained in MS4W README somewhere in your installation. It's also explained in the WMS example (example 1.6?). Finally, you have your SHAPEPATH pointing to "/ms4w/httpd.d/tutorial/data". Did you install the tutorial in the httpd.d directory? If so, you might want to move the whole tutorial to "/ms4w/apps"--that's where your MapServer applications are supposed to be. You can then edit your httpd_tutorial.conf to have the lines I have above. This is just something to follow to keep your MS4W installation clean. I hope this helps. Good luck!

In-Reply-To: <20050413135530.34352.qmail@web32015.mail.mud.yahoo.com> Message-ID: Hi, I just replied to Lawal's post and that reply should answer your issues as well. In your case, it looks like you installed the tutorial directly under "/ms4w/Apache/htdocs"--that's fine but you're missing an opportunity to learn more about Apache. ;) Anyway, I see that you created a temp directory under tutorial but you're pointing your IMAGEURL to "/tmp/"... It should point to "/tutorial/tmp/". This is really a web server issue--MapServer, when processing your mapfile, uses local paths (that's why you have SHAPEPATH, IMAGEPATH, and all other PATHs pointing to your local directories). However, after MapServer finishes processing the mapfile, the output images need to be referenced in web server terms--the resulting HTML file that the browser reads has to reference the location of your images in web server terms, not as local paths. You need to understand what your web root directory is and what an alias (or virtual directory) is as they become important for referencing MapServer generated images. So, IMAGEURL is really the web server alias for your IMAGEPATH and relative to your web root directory (which is "/ms4w/Apache/htdocs"), it is under "/tutorial/tmp/". This isn't an issue when using "mode=map" and when you're not using WMS or WFS layers. When you set "mode=map" you're telling MapServer to stream the image directly to the browser and forego writing images to a tmp directory. This is also why you didn't have an issue with the images until now (when you use "mode=browse"). I hope that clarify things up a little...

Date: Thu, 14 Apr 2005 06:09:38 -0700 Subject: shapefile polygon opens in arcgis but n ot mapserver Message-ID: Hi, I've had to deal with a similar issue connected with shapes with M values (I can't recall if they also had Z). When I had the entire polygon within the view it was visible but if any portion of that file extended outside of the viewer the rest of the features for that shapefile would disappear. I was able to get around this by removing the z and m values and exporting a plain 2D shapefile. After that everything worked. The issue appears to be the way mapserver opens or handles M and possibly Z shapes. The shapes were created with arcgis 9.0 which may be part of the problem as ArcGIS products tend to handle and create shapefiles a little differently than arcview 3.x.

Do I need to > worry about maxing out my DB's allowed connections? The DB connections are never closed till fastcgi shutdown. There are things you can configure in the apache .conf file to control how many fastcgi processes may be started, and how long they are kept alive. You may want to tune these to try and cleanup fastcgi processes after a set period of inactivity. Generally speaking, yes, you do need to be wary about database connection consumption in environments where the number of connections is limited due to licensing or resource restrictions. > Say, the documentation on the PROCESSING keyword is > rather sparse.

In a non-FastCGI situation the closes are deferred till the cgi process is ready to terminate. This effectly allows for "connection sharing" between layers but does not help the next cgi request that starts up. So for a map with multiple layers drawing from a single database the deferred closing can still provide a significant speedup over opening a connection for each layer rendered. The PROCESSING keyword is a bit of a hack to make it easy to add new features. If we now consider the pooling mechanism sufficiently mainline perhaps we should be making CLOSE_CONNECTION a proper keyword in mapfiles, instead of going through the PROCESSING directive.

In mapdraw.c, the function "msDrawShape" : There a switch on layer type in case MS_LAYER_POINT there is a loop on "shape->line[j].numpoints" but if it's a point layer i think there is only one point so shape->line[0].point[0] is the point we want to draw. If we agree that the shape can only have one point we can pass a shape object to "msDrawMarkerSymbol" instead of a point object and in mapimagemap.c in the function "msDrawMarkerSymbolIM" we can get the point x,y with shape->line[0].point[0] and the shape index with shape->index so we can get the point index in datasource like polygons So my question is why point layer are process like a polygon layer by msDrawShape ?

Within the mapfile documentation, the Legend object is described here: http://mapserver.gis.umn.edu/doc44/mapfile-reference.html#legend I use CGI mapserver, with HTML templates, using the [legend] tag, with no need to set any 'mode=legend' value anywhere. The legend object of the mapfile tells mapserver to process it when the map / scalebar / reference image are generated.

There is a little trick that you should not run ogrtindex from the directory which contains the data (otherwise it does not create an absolute path to the data in the LOCATION item). So run it from the directory where you installed FWTools eg: for %i in (d:\data\*.shp) do d:\programs\fwtools\bin\ogrtindex mytileindex.shp %i About the performance, have you created shapefile qix indexes (using shptree?). Also, it depends on the GDAL/OGR version whether or not the qix files are actually used (that's a relatively new feature). If I recall correctly that was added in GDAL/OGR 1.2.6, but Frank knows for sure. I think Mapserver normally scales well with a lot of LAYERs, it may have to do with your data structures and not the amount of LAYERs.

The problem now is with the overviews... Each original Landsat file is about 300 Mb, so when MapServer is requesting each tile it is asking for a 300 x 3 Mb file (RGB bands). I created overviews with "gdaladdo -r average cover.vrt 5 10 50 100" but when trying to access all of them (100 landsat images) in the webclient it takes a lot of time. If I first zoom in (lets say the UK) and then request the layer (Europe Landsat 5) the performance is ok. You can take a look at http://iceds.ge.ucl.ac.uk:8080/viewer/iceds/index.html Could this have to do with the overviews? Perhaps not enough levels? Can it be also the number of tiles MapServer is requesting at the same time (100 tiles)? Should I aggregate them first?

Nuno, The traditional approach to this is to prepare composite "overviews" that would apply at large scales. So you would set a MAXSCALE on the tile indexed layer at some reasonable level (perhaps a scale were the user is likely to be seeing more than 9 images or so. And then create a new layer - the overview version - with it's MINSCALE set to the same thing. This layer can be just a single file at a very much reduced resolution - matching the scale at which it kicks in. I would suggest actually using MapServer to generate it from the other layer -- perhaps using shp2img or just doing it on the web. Now, I am fluffing over lots of details of how to compute the scales, and build the alternative overview but then I get confused about those details. :-) They are solvable but a bit messy.

For example: just pulling the points from (in my case: a MySQL db) a database and displaying them without a shape file? And is it possible to do queries on that layer, or displaying the attribute data? I assume not, because there's no associated dbf file.

I am using PHP. I got the source code from http://mapserver.gis.umn.edu/win32binaries.html (ms441oci.zip) It is compiled with GDAL, but GDAL that it's compiled with doesn't support MrSID. I got LizardTech DSDK and compiled my own GDAL 1.2.5 It compiled fine, I'm able to view MrSID images with the mrsidviewer. gdalinfo works fine on my mrsid image, see output below. I want to use MrSID since my MrSIDs are only 60-70 Mb, and when I convert them to TIF - they grow to 1.7 Gb each. The question is: how do I make my Mapserver 4.4.1 from http://mapserver.gis.umn.edu/win32binaries.html work with my GDAL 1.2.5 ??? Of course, I could compile my own Mapserver - but that's a very error-prone process on a Windows machine. Does anyone know of an option to reconfigure Mapserver 4.4.1 installation without having to rebuild it? Do I simply need to point it to use frmts\mrsid drivers? Is there any way to achieve this? I will be glad to share my GDAL 1.2.5 with MrSID support. Here is how I defined my MrSID layer: LAYER NAME "14_1_1.sid" data mrsid type raster status default END Here is gdalinfo output for my mrsid image: C:\ITS\GDAL\125\bin>gdalinfo C:\ITS\Apache2 \htdocs\statewide\shape_files\mrsid\1 4_1_1.sid Driver: MrSID/Multi-resolution Seamless Image Database (MrSID) Size is 24066, 25370 Coordinate System is: PROJCS["unnamed", GEOGCS["NAD83", DATUM["North_American_Datum_1983", SPHEROID["GRS 1980",6378137,298.2572221010002, AUTHORITY["EPSG","7019"]], AUTHORITY["EPSG","6269"]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433], AUTHORITY["EPSG","4269"]], PROJECTION["Transverse_Mercator"], PARAMETER["latitude_of_origin",0], PARAMETER["central_meridian",-99], PARAMETER["scale_factor",0.9996], PARAMETER["false_easting",500000], PARAMETER["false_northing",0], UNIT["metre",1, AUTHORITY["EPSG","9001"]], AUTHORITY["EPSG","26914"]] Origin = (653334.000000,3916062.000000) Pixel Size = (0.30000000,-0.30000000) Metadata: GEOTIFF_CHAR__GTModelTypeGeoKey=ModelTypeProjected GEOTIFF_CHAR__GTRasterTypeGeoKey=RasterPixelIsArea GEOTIFF_CHAR__ProjectedCSTypeGeoKey=PCS_NAD83_UTM_zone_14N GEOTIFF_CHAR__ProjLinearUnitsGeoKey=Linear_Meter GEOTIFF_NUM__1024__GTModelTypeGeoKey=1 GEOTIFF_NUM__1025__GTRasterTypeGeoKey=1 GEOTIFF_NUM__1026__GTCitationGeoKey=IMAGINE GeoTIFF Support Copyright 1991 - 2001 by ERDAS, Inc.

The answer was actually a combination of issues: 1) I compiled the base MapServer (and dependent libraries) on a VC.NET installation - not VC6. That was mistake #1. I have now recompiled on a VC6 installation. 2) I compiled all dependent modules with the /MT flag not /MD as is the default with the win32 makefiles. 3) I made sure to include the -DUSE_THREADS option as part OPTFLAGS when compiling MapServer.

The reason that the points are being retrieved and used is that these points trace the outline of the point object. However the work that was done on the code did not provide the ID of the point objects to the mapimagemap.c module for inclusion in the image map code to the web page. So I proceeded to modify some modules to pass the IDs down to this code and actually output them to the image maps. These changes were only implemented for VECTOR type symbols. Now I am getting image maps outlining the point symbols with the point IDs included in the event calls. My changes required making changes to the mapdraw.c module which is at a high level in the code and also I only modified the PHP version of MapScript. To this date I haven't submitted my changes to the system since I don't know how to go about doing this. Currently I am having trouble with my build on my Windows system but I don't think it is caused by my changes since I have seen other people reporting these problems on the list. I will try submitting my changes to the list soon though. I would be happy to provide you with my code changes if you want to try building this on your Redhat system. Just let me know if you want me to send this to you.

From what I read in the archives etc, the index needs to be set to use queryByPoint() on the dynamic layer and the released code (4.4.2 - I just compiled it to confirm and it is broken, index is readonly) of mapscript. Index gets set as -1 for all shapeObj's added to the layer and queryByPoint doesn't work. I'd be interested to know how are querying the dynamic layer so that you can determine which point was clicked on and therefore, which row of data to extract from a database.

I remember one of my old posts in which I had similar problems, might be informative (or confusing :) ): http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0407/msg00673.html Secondly, the OGR issue, see the 1.2.6 release notes: http://www.intevation.de/pipermail/freegis-list/2005-March/002209.html Shapefile Driver: - Added support for MapServer style spatial index (.qix). So that's fairly new. Does your gdal12.dll have version info? You can check with your right mouse button and then the version tab.

I should create a .qix file for each shapefile using shptree. Then once they all have a .qix, then I should create the tiledindexes using ogrtindex? Will the tileindexes take the .qix into consideration? Second, I'm not sure what you mean by the following: "Also, it depends on the GDAL/OGR version whether or not the qix files are actually used (that's a relatively new feature). If I recall correctly that was added in GDAL/OGR 1.2.6, but Frank knows for sure. " Thanks for all your help....

My table has the longitudes and latitudes of the points. I read in the coordinates from the postgres table, project the point into the map projection and plot them. I cannot do map queries as you said, but I work around that by making the map image a client side image map and make the points clickable. This makes navigating the map trickier... I can't use the same interface that most of the mapserver apps i've looked at use... but it is working ok. I'm almost done with the application now on a funcitionality level and then I'll be working on the interface because right now it is actually pretty slow to use. -Jeff ----- Original Message ----- From: "Gavin Simpson" To: Sent: Friday, April 15, 2005 7:06 AM Subject: Re: [UMN_MAPSERVER-USERS] dynamic point generation with php-mapscript > Wouter Schaubroeck wrote: >> Hi, >> >> I was wondering if anyone would know some good examples of generating >> dynamic points with php mapscript?

It creates a dynamic layer. You do not need to pre-define the layer in the .map file.

Your layers and output are using one projection with one type of unit (feet? meters?), but then you are trying to place a point on the map using decimal degrees units. To check this, try placing a point with an x value between -994934.821920 and 322333.423383 and a y value between 5173124.716504 and 6431993.097353. I'd image it would show up just fine. What you'll need to do is define a projection block in your layer definitions. Mapserver has no trouble mixing different layers of different projections, but it can be difficult at first to figure out what projections are and how you need to set them up. I would suggest doing some looking through mapserver examples and listserv archives regarding projections and then asking specific questions you may have to the group. -Camden Daily On 4/15/05, sc wrote: > Hi Camden > > I have altered my code to use your function but I still cannot see my > 'point', I have also switched > off all other layers and it is still not visible.

Your layers and output are using one projection with one type of unit (feet? meters?), but then you are trying to place a point on the map using decimal degrees units. To check this, try placing a point with an x value between -994934.821920 and 322333.423383 and a y value between 5173124.716504 and 6431993.097353. I'd image it would show up just fine. What you'll need to do is define a projection block in your layer definitions. Mapserver has no trouble mixing different layers of different projections, but it can be difficult at first to figure out what projections are and how you need to set them up. I would suggest doing some looking through mapserver examples and listserv archives regarding projections and then asking specific questions you may have to the group. -Camden Daily On 4/15/05, sc wrote: > Hi Camden > > I have altered my code to use your function but I still cannot see my > 'point', I have also switched > off all other layers and it is still not visible.

Those are automatically used by GDAL. The objective of using a separate layer in MapServer is so that you can have an overview that is "all-in-one" file. What is killing you with showing overviews of 300 files worth of data is all the per-file overhead. This is modest for 1 or 5 files, but open 300 GeoTIFF files, and parsing all the headers ends up being quite a bit of work. So, the overview layer should refer to a single big overview at a much reduced resolution from the original files. The tricky part is building this overview, as I mentioned before. There are a variety of approaches, but for my money the easiest is to use Mapserver itself. Do you need details on this process? I have never *actually* done it myself.

At one time, you had to pay $500 to purchase the decompression SDK (which could be used with GDAL), but this restriction was lifted last fall (a quick google will find a screed by yours truly railing against this). The situation is *much* better now that the decompression SDK is freely available for personal use. The problem right now, in my opinion, is that neither ECW nor MrSID decompression support are really redistributable because of the effort required to enforce their licensing restrictions. For a distribution builder, this presents a problem. At one time, in my "Kitchen sink" binaries, I had ECW and MrSID support, but now that I know more about the licensing stuff, I am refraining from doing that anymore. It isn't worth the hot water I could potentially get in. It's unfortunate, because building up a MapServer+GDAL+xyz libraries on windows is a pretty formidable challenge for most users, especially those who just want to be able to use publicly available data like the NAIP imagery (which only comes in MrSID form). Another thing to note is that the consensus is that the current ECW license pretty much prevents its use with MapServer. The next revision of the license is supposed to allow its use with MapServer and others. Even so, it is probably unlikely that you'll see a MapServer binary distribution that you can download and use with support for ECW (or MrSID) without compiling everything yourself.

Message-ID: Dear list, I'm finally admitting defeat one this one and am asking for some help or a pointer or two. I compiled mapscript 4.4.2 on my Fedora Core 3 box, but replaced php_mapscript.c with the one Camden Daily submitted to bugzilla to fix the bug that won't allow you to set the index of a shapeObj. Note that I have also compiled the latest nightly and I get the same behaviour as I describe below but reverted to 4.4.2 because the nightly was doing some strange things when drawing polygons. I am adding points to a layer dynamically from a MySQL database and the lat/lon stored therein. As well, I am adding point features (lines with one point) to the same layer and am setting the index for the point so I can query this layer later. This works fine and I have a zoomable, map of Europe with the points of my lakes displayed. When I come to query the layer using queryByPoint(), no matter what I do, I always end up with the last shape point I added to the layer I'm trying to query. So I always get 1 back from getNumResults() no matter where I click on the map - over a point or not, and the returned shape from getShape() is always the last shape I added. I can't see how to make this work properly - what am I doing wrong? If you want to see what I mean, go to http://ecrc3.geog.ucl.ac.uk/maps/test/europe.phpms select the query radio button and click on a point - or anything. The debug code will be displayed next to the map illustrating the problem nicely.

You create a point, create a line, and then add the point to the line. Then you create a shape and add it to the layer, but it does not appear that you ever add the line to the shape. Try adding this code after you create your shape and line: $shape->add($line); If things still don't work, you might try testing out queryByPoint() against a point layer defined in a shapefile.

Does the multi-threading capability affect the server specs? This is a very difficult question to answer. Please describe the tasks you will be using Mapserver for. Where will the data layers for Mapserver reside? - External WMS ? - PostGIS ? - Shapefiles ? - Raster ? What is your budget? In general, spend your money on fast RAID disk solutions. IO is almost always the bottleneck. Get a SCSI 15K U320 RAID solution and you should be very happy. But even with such a hardware solution, there are software tuning tasks to do with Mapserver data sources / layers / etc... (This could be a very long email.) Please try to be a bit more specific and I am sure folks will chime in on the list with what works for them.

For example, parcel attributes (like sale_price) are naturally associated directly with a parcel shape column: however, you often want to aggregate them (average over an area or the like). So I created a PL/PGSQL function that took a table, column, number of rows and number of columns and generated a new table with just a grid of box shapes that cover the same area. I call it makeBlocks(): # select makeBlocks('parcels', 'parcel_shape', 'parcel_boxes', 'parcel_box', 10, 10 ); Then, I added columns for attributes I wanted to aggregate: # alter table parcel_boxes add column avg_sale_price double precision; And ran a NASTY SLOW query like this: # update parcel_boxes set avg_sale_price = (select avg(sale_price) from handyViewWithSalePrice where parcel_shape && parcel_box); (Obviously, handyView is nastier and better named :) It takes FOREVER, but when it's done, it works! It took about 5 minutes for that 10x10 grid, and I'm about to start a 100x100 that might take all day :) I just thought I'd share the idea (and the PL/PGSQL) with the group. Please forgive the code: it's my first forray into PL/PGSQL. If anyone has any ideas on ways to make it faster (or better) please let me know.

You could look at that for an example. Beginning with version 4.6 we have a standard imageObj.getBytes method that is shared by all mapscripts (except PHP). However, it requires a small bit of extra code that is language specific and converts getByte's output structure into a string or array type for the target language. So far we only have these typemaps for Java and Python. The C# module is in need of someone(s) who will study the details of SWIG/C# and implement the proper typemap. Not being a C# user myself, I can not justify spending my personal resources on this, but I can provide some general assistance and coaching on how to write SWIG typemaps. cheers, Sean -- Sean Gillies sgillies at frii dot com http://users.frii.com/sgillies From ortelius at GMAIL.COM Sun Apr 17 06:36:09 2005 From: ortelius at GMAIL.COM (Jeffrey Johnson) Date: Sun, 17 Apr 2005 06:36:09 -0700 Subject: Search returned no results Message-ID: I'm having trouble getting query mode to work in my first mapserver application.

Message-ID: BC, I'm pretty new to MapServer myself, but since your not having any luck I thought I'd share my limited experiences. Basically I can't get MapServer with mapscript to work when I compile and link Mapserver against GDAL 1.2.6, but if I do the same against GDAL 1.2.5 everything works as it should. Since nobody else has mentioned this I'd just assumed it was something I was doing wrong. But perhaps it is worth a try?

Thanks Toomas, I tried what you suggested: PHP and Mapserver are explicitly using --with-gd=/usr/local but I still segfault. I even tried compiling PHP with no GD support, but no luck (segfault). FYI, I did have 2 versions of GD installed, but I uninstalled one and am left with gd-2.0.33. Still segfaulting BTW, here is my GDAL config (just in case there are other blatent conflicting libraries I am overlooking): ./configure --enable-shared --with-png=/usr/lib --with-jpeg=/usr/lib --with-pg=/var/lib/pgsql/bin/pg_config --with-geos=yes --with-libtiff=/usr/local/lib --with-geotiff=yes --with-ecw=yes (ecw did not work) Any other thoughts?

Thanks bobb From fabrice.thevenon at CG64.FR Thu Apr 14 00:50:34 2005 From: fabrice.thevenon at CG64.FR (Thevenon Fabrice) Date: Thu, 14 Apr 2005 09:50:34 +0200 Subject: Installation - phpmapscript and postgis Message-ID: Hi all, We are preparing a migration from phpmapscript 3.6 to phpmapscript 4.4. I also would like to use PostGis soon (I am waiting for PostGis 1.0). I work under WinXP and use the binaries from maptools.org and don't know very much about compiling source code. My question is : I download the phpmapscript_44.dll from maptools this morning (mapserver-4.4.2-win32-php4.3.11.zip). In a near future, the PostGis 1.0 version will be released (today, it is 1.0 RC6). Will the phpmapscript_44.dll still work with postgis 1.0 or will I need to download a new version of phpmapscript_44.dll, compiled with postgis 1.0? Thanks !

When MapServer processes your mapfile, it works locally--your SHAPEPATH, IMAGEPATH, etc., all point to local paths within your OS. However, when MapServer finishes processing the mapfile, the rest of the work is handled by the HTTP protocol. So everything has to be referenced via HTTP URLs--that's where the IMAGEURL comes in. Let's say you have MapServer output images in e:\var\www\html\tmp\ (both Unix and DOS slashes are valid in MapServer except those pointing to URL's). Also, you have your web server (Apache or IIS) point to this directory as "/tmp/". "/tmp/" is called an Alias by Apache or a virtual directory by IIS and is referenced relative to the web root URL (say, http://localhost/"). So, in this case "/tmp/" is really pointing to "http://localhost/tmp/". In MapServer, the parameter IMAGEURL references the IMAGEPATH directory but in HTTP URL terms. In this case you'll define the paths: IMAGEPATH "e:/var/www/html/tmp/" IMAGEURL "/tmp/" I hope that clear things up. -Perry PS: Not to confuse you or anything but you can probably define non-HTTP urls (as in you original mapfile) but you have to append "file://" instead of "http://" when referencing the imageurl. ) Things that make you go, hmm...

I am trying to get a layer named "test/test1" - yes, with the forward slash included. Mapserver translates the forward slash and the cascaded server cannot find the requested layer. Is there a way (perhaps with a script) to edit on-the-fly all the requests MapServer sends to the server being cascaded? In this way I would try to unencode the forward slash before sending the request.

Now, if I click on any part of the region inside a city on the main shapefile, how can I load the shapefile corresponding to the city on which I clicked. Is there any standard way to achieve this? Did anyone have an idea which they think is the standard way? I appreciate any help in this regard. Thanks and Regards, Giridhar p.s Currenly I am using ESRI shapefiles.

Message-ID: Sean, Umberto, thank you for your prompt replies and help. For the past couple of days I've been testing using synchronized blocks and methods: mapObj mapobj = null; synchronized(mapobj) { mapobj = new mapObj(path); } ...... synchronized(map) { mapURL = mapbean.renderImage(map.draw(), "_mainmap"); } ...... public synchronized String renderImage(imageObj img, String suffix) { long rnd = Math.abs(new java.util.Random().nextLong()); String imgfile = rnd + suffix + '.' + img.getFormat().getExtension(); img.save(img.getImagepath() + imgfile, map); return img.getImageurl() + imgfile; } Using synchronized has certainly improved stability. However I haven't yet compiled Java Mascript using the latest CVS because I am developing on Windows XP and and there exists no java mapscript make file for Win32. Once we put the first version of my project up for public testing it will be on a Linux machine, I will then be able to test the latest CVS. Until then I will hope that a pre-compiled Java mapscript will be uploaded to http://hobu.stat.iastate.edu/mapserver/build_output; Thanks, Daniel On Mon, 11 Apr 2005 10:01:38 -0600, Sean Gillies wrote: >On Apr 11, 2005, at 3:49 AM, Umberto Nicoletti wrote: > >> On Mon, 2005-04-11 at 03:33 -0500, Daniel Caldeweyher wrote: >>> Hi everyone, >>> >>> first of all I would like to thank all the developers for this great >>> piece >>> of software. >>> >>> I am working on a GIS project for my University using JavaMascript on >>> Tomcat 5.5.7.

The TIGER/line source data has to be processed to identify these polygons. I don't believe any software that does this is freely available (anyone know otherwise?). However, the data available on ESRI's site appears to be distributed under the same terms as the TIGER/line files.

Nuno, The Arc/Info binary grid form is internally tiled in 256x4 bricks, so access from MapServer (via GDAL) to binary grids will generally not have to read much extra data. This does not apply to ascii grids which are of course dead slow to use at any reasonable size.

I have experimented with different numbers and after reading a bit more, I have discovered that it make no difference (in my case) how I divide it up. As a matter of fact, my application performs SLOWER the more files that I have. What I am trying to do is to display an area with parcels of land. I have two identical layers... one to display all of the parcels and the other to only display the selected parcel. It is extremely slow when querying for by parcel id. Because of this, I need to put the second layer (at least) in a database so that the parcelid field can be indexed.

I have an area that I would like to display parcels of land and search for a parcel by parcelid. I use two layers for the parcels: one layer to display all of the parcels at a certain level and the second to highlight the selected parcel. I have gotten my application to work using shp/dbf/shx/qix files, but it is extremely slow when searching for a parcelid (e.g., 25 seconds). The major time delay is searching for a particular parcel id. Using shp2mysql.pl, we have gotten the data into the mysql db. I indexed on the parcel id. I am having trouble now filtering for the parcelid. After getting several errors, I decided to see if I could display the first layer using the db. It showed up nicely, but I am still getting errors on my queried layer. Here is what I have in the mapfile: #layer to display all of the parcels LAYER NAME "Parcels" STATUS ON TYPE POLYGON CONNECTIONTYPE mygis CONNECTION "host:dbname:user:pass:bin:" DATA "geo from Parcels feature, Parcels_bin geometry" CLASS OUTLINECOLOR 0 255 0 TEMPLATE "template.html" END MAXSCALE 40000 TOLERANCE 0 TOLERANCEUNITS PIXELS END # layer to display selected parcel LAYER NAME "Parcels2" STATUS OFF TYPE POLYGON CONNECTIONTYPE mygis CONNECTION "host:dbname:user:pass:bin::" DATA "geo,PARCELID from Parcels2 feature, Parcels2_bin geometry" FILTER "feature.PARCELID='C0244R F00005'" CLASS Name "MAP" OUTLINECOLOR 0 255 0 TEMPLATE "template.html" END MAXSCALE 40000 TOLERANCE 0 TOLERANCEUNITS PIXELS END Here is the code that I use to query for the parcel id: getLayerByName("Parcels2"); if($my_layer->queryByAttributes('PARCELID', $_REQUEST['parcelid'], MS_SINGLE)==MS_SUCCESS) { $my_layer->open(); $my_layer->set("status",MS_ON); for($k=0; $k < $my_layer->getNumResults(); $k++) { $my_resultcache=$my_layer->getResult($k); $my_shape=$my_layer->getShape($my_resultcache->tileindex, $my_resultcache->shapeindex); $my_array=$my_shape->values; $map->setextent($my_shape->bounds->minx-100, $my_shape->bounds->miny-100, $my_shape->bounds->maxx+100, $my_shape->bounds->maxy+100); //print_r($my_array); } $my_layer->close(); } } else { print "Parcel ID " . $_REQUEST['parcelid'] .

It is not currently possible to get a random looking fill, but you might try something like creating two symbols the are rather large like: +-----------+ + * + + *** + crude tree randomly positioned in the symbol + # + + + + + +-----------+ And another, but don't make it with the same height and width and make it with different tree shape in different random position. Make the background of symbols transparent. Then fill your polygon area with both symbols. The pattern will be regular but the different sizes with cause an interference pattern so it will be harder to detect that it is regular. Play with the symbol sizes until you get a result you like. You will even get the two images overlapping in some cases. I haven't tried this, but it seems like it might work and I think it would look pretty good. I would be very interested to see the results. -Steve W. Dan Taylor wrote: > Hi, > > I want to show an area of woodland on my map.

You have three options: 1) Generate a large raster image with randomly placed trees, and use this as your symbol. This is what MSN Maps use, and it's rather easy to implement in MapServer. Here's a sample using MapServer: http://img95.echo.cx/img95/4484/a14mm.gif 2) Use MapScript to randomly select a bunch of points. Then, check each point to see if it is withing a woodlands shape. If so, use MapScript to draw your tree symbol there. 3) Similar to the solution above, but doesn't need MapScript. Choose a bunch of random points , and draw your tree symbols there using a new layer. These points can even be the same from map to map, so you can hardcode these values into a new shapefile or right into your map file. Finally, overlay this with a layer that only fills in color where your woodlands AREN'T-- in other words, you'll need a shapefile that can identify areas that are not woodlands.

I say it's very beta since it doesn't do any sort of collision detection, and in some cases can produce upside down or backwards labels. I am working on those issues, as well as adding auto line-wrapping and auto- placement features sometime in the future. Still, if anyone is interesting in playing with the present version, I can share the function and/or the madness behind it.

Message-ID: Following up from another thread, I'm currently attempting to show woodland as a polygon filled with tree images. It has been suggested to me that I use two or more transparent images to fill the polygon and get the effect I want. However, I have hit another problem. I get the warning: "Warning: [MapServer Error]: loadSymbol(): Unable to load GIF symbol" when I try to load a gif image using the following in my map file: SYMBOL NAME 'tree3' TYPE pixmap TRANSPARENT 127 IMAGE 'symbols/trees.gif' END If I try to use a PNG image it won't go transparent. Using Paint Shop pro I have examined the palette to find the index of the colour I want to be transparent (white), so as far as I know it's correct. The image ends up looking wrong. See mapfile snippet and link for example. SYMBOL NAME 'tree4' TYPE pixmap TRANSPARENT 0 IMAGE 'symbols/trees2.png' END http://logicalgenetics.com/assorted/upload/output_not_working.jpg So I have two questions... 1) Can transparent PNG images be used and if so, how? 2) Why can my version of mapserver not load GIF images?

In-Reply-To: <830dd37405041902505aed039e@mail.gmail.com> Message-ID: Dan, With my very limited experience working with images and photoshop you need to make sure that you save set the image as having a transparent background and select the index before you file it. Then you need to tell mapserver in the symbol definition what index is also transparent. I don't think it will work it create a normal (non transparent) image and then tell mapserver to treat some index value is transparent. I have attached a transparent png image where I use "transparent 1" in my symbol def. try replacing your tree with it and see if that works. -Steve Dan Taylor wrote: > Following up from another thread, I'm currently attempting to show > woodland as a polygon filled with tree images.

Message-ID: I've sometimes had problems getting PNGs do display transparency using the "Transparent" keyword with an index-- even when I specify the proper index, the specified color doesn't become transparent. The best solution I've found is to ensure the PNG was saved natively with transparency. I'm not sure how it would be done in Paint Shop Pro, but in Photoshop you can save the PNG as a transparent PNG file and can even specify the transparency color. I can use this PNG in Mapserver fine-- the key is then to not use the "Transparent" keyword at all. If you want, you can post a link to your PNG file and I'd be happy to see if I can get it go transparent. As far as GIF files goes, it might be that your version of mapserver wasn't compiled with GIF support. You can type "mapserv -v" at the command line (on Windows), or "./mapserv -v" at a shell prompt to find out.

If you know which polygons you want to color ahead of time, you could set up a CLASS with an EXPRESSION that only fits that polygon and set a style to symbolize that poly.

Ryan, I would suggest the issue is extents related. Likely all your vectors are getting drawn in one pixel. I would suggest you use some utility to get the extents of your dataset in their intrinsic coordinate system which would be lat/long if they are tiger/line data (that hasn't been reprojected). For shapefiles and a few other formats, you could use ogrinfo. eg. ogrinfo -ro -so -al abc.shp > Here is the web address i access: > http://localhost/cgi-bin/mapserv?map=/usr/bin/apache/htdocs/mapserver/simple.map&mode=map&layer=Freeways&mapext=1.00%201.00%2050000.00%2050000.00&imgsize=300%20300 > > And my map file is here: > > #-------start of map file---------------# > NAME sampleMapServer > # the below extents and size are provided in the URL and so must be removed > #EXTENT 482925.85 3625874.39 497393.16 3617143.43 Note, just because you are listing the extents in the url doesn't mean you have to remove them from the map. The info passed in the url just overrides the info in the map file. I generally try to fill out reasonable information in the mapfile so I can use utilities like shp2img for debugging purposes. PS. there are lots of possible reasons your map could be failing to draw besides the extents issue, but it is pretty hard for us to remotely debug without all supporting files, and a clear understanding of what version of mapserver you are running. Generally "mapserv -v" output is more useful than your configure line.

Message-ID: Hello All, PROBLEM: Upgraded PerlMapscript does not work with web app written using older PerlMapscript BACKGROUND: New to the list, and relatively new to Mapserver and Perl MapScript. We recently upgraded our mapserver installation from some older version (perhaps 3.x) to 4.4.1. We have a web app that uses Perl MapScript to navigate/explore some maps and such - pretty standard. As part of the MapServer upgrade, I upgraded PerlMapscript because I was told that the previous Mapserver installation we had (which I did not build or install) did not have TIFF raster support built in, and we needed it for the next version of our little PerlMapscript web app. Our new mapserver executable reports that it supports as many raster formats as we're going to be able to use (png, bmp, gif, tiff, gd, pdf, ming, etc..). I'm fairly sure I've built it right because it works for some other purposes. So, after building the newest mapserver and then installing the perl mapscript which came with it, the web app does not work. I saved the old PerlMapscript libs and put them back in place, and stuff works again. Good... CURRENT STATUS: We either need to know that the old version of Perlmapscript did have support for TIFF rasters, or figure out how to make the new version of mapscript and our webapp work together. I am a sysadmin who does not know anything about Mapserver beyond what it takes to build it. I am a Perl programmer (no Guru, but still). I do not know enough about GIS to write a Mapfile from scratch. Currently, the web app gets to the following line: v---snip--- #Create map object that refers to full extent map my $mapObjFull = new mapscript::mapObj("../mapserver/malibu.map") or die("$mapscript::ms_error->{message}"); warn "Got Here 2.5"; ^---snip--- And never prints "Got Here 2.5" or continues or does anything. There are, of course, various "Got Here 2.x" items before this point, and it prints all of them (no I don't use debuggers, I use 'warn' statements). I tried using the $ENV{MS_ERRFILE} or whatever it is to setup a debug log - it never seems to work, no matter where I put the file or what permissions I give it. So that hasn't helped. As I said, this is a web app, so my "Got Here" statements print into the Apache error_log file. I decided to try a command line version to see if I missed anything... But I didn't. v---snip--- #!/usr/bin/perl -w use mapscript; use XBase; my $mapObjFull = new mapscript::mapObj("../mapserver/.map") or die ("$mapscript::ms_error->{message}"); warn "Got Here 2.5"; ^---snip--- I run it and I get errors about only using the $mapscript::ms_error variable once. So I commented it out: v---snip--- #!/usr/bin/perl -w use mapscript; use XBase; my $mapObjFull = new mapscript::mapObj("../mapserver/.map"); # or die ("$mapscript::ms_error->{message}"); warn "Got Here 2.5"; ^---snip--- And now when I run the thing I just get: "Segmentation fault" If I run the same script with the old mapscript, I get: "Got Here 2.5" Which is what I want, at least at this point. I tried re-swigging the perl mapscript and it did change the output a bit. Before re-swigging the output of my script was: "Killed" And now I get the segfault thing. My perl version is 5.8.1 My Linux is Mandrake 9.2. Mapserver is 4.4.1 and PerlMapscript is whatever version comes with MS 4.4.1 At this point, I just went through major headaches building MS 4.4.1, so I would prefer not to upgrade to 4.4.2, and I cannot upgrade Mandrake 9.2, although I can rip out software and recompile pieces by hand - ie I don't have the install media for a newer version of Mandrake, though I doubt that is the problem. Apache is 2.0.47, though I doubt that matters since I get errors at the command line. The machine has 1gb of RAM and a P4 cpu. I can't think of any other details, but I would be very grateful to anyone who even hazards a guess here - I have no idea what to do. I did see various posts on the Wiki about Perl 5.8 and Mapscript, but I never had any trouble building mapscript - ie. No errors during the mapscript build. Is the mapscript wrapper something that works completely independantly of the Mapserver that is installed?

You can Query multiple layers so if yo query the state layer then you will know about which state was clicked on and if you query the city layer you will know what city was clicked on or if NO city was clicked on. You can then get the extents of the city shape that was returned in the query and use that information to zoom the map to that city. 1) setup your mapfile to support queries 2) get the click coordinates 3) query the layer(s) 4) get the extents of the city 5) set the extents of the map to the city extents 6) redraw your map -Steve W. http://imaptools.com Giridhar Manepalli wrote: > Hello, > Anyone there to answer my question? :-( > > I am currently trying few options with php/mapscript to embed in my > application later on. > > Say that I have a shapefile for a state with the geometry being > polygon.

Luca, What do you mean by a "plan picture"? Generally speaking it should be easy to create a layer from a set of orthophotos in MapServer by creating a tileindex for them (with gdaltindex) and using that tileindex for a layer. For performance purposes it may be necessary to create overviews for the orthophotos, and to manage a seperate "overview" layer for large scales.

Luca, I'm afraid I am still confused about what you want. Are the inputs actually ortho-photos or raw airphotos? If they are orthophotos then I don't see what you mean about not being able to overlap them due to distortion.

But I didn't. Nicholas, A LOT has changed (for the better) between 3.x & 4.4 so alterrations to the code AND the 'knowngood' mapfile need to be expected. However, there is a direct relationship between the mapserv executable and mapscript. If you can locate the mapserv executable from your previous install and run it from the command line with the -v option, as you expect, it will list whether tiff support is available. Otherwise you can always do the guess & check method of adding a raster tiff layer to the mapfile used in the app and then drawing it (try this with a 256 color, 8-bit, no compression, tiff with an associated .wld file). Either way you will want to upgrade at some point but this may save you some immediate trouble.

You still need inner and exterior orientation parameters of the images, camera parameters and lens distortion measurements. Furthermore you need a digital elevation model to do a proper orthorectification. If the images have been used for photogrammetric mapping, the orientation parameters probably exist already, but then you still need a DEM. Just be aware that if the images have been oriented using single model setups instead of using bundle adjustments / aerotriangulation, you will probably get a poor result. Bottom line is that this is no easy task unless you already have a full blown orthophoto production setup (which I assume you don't have).

Don, I'm confused, from your previous posts I can't determine if you imported your data into mysql using the shp2mysql.pl routine. If not, that is most likely the problem. The third error line above seems to indicate that the geometry fields expected by the mygis reader do not exist. If you do a 'select * from \g' at the mysql prompt does the data appear to be there?

Cave, My theory on this one is that the setProjection may work correctly but there are other parameters which need to follow for the map to render correctly. The mapserv cgi handles all of those settings automatically as opposed to mapscript where you need to set them manually. Until I can look at the source I don't know what else is missing.

LAYER NAME "qru_fnl1" CONNECTIONTYPE postgis CONNECTION "user=root password=c3n5u5 dbname=census host=localhost" DATA "the_geom from qry1 using srid=-1" ... I assume that qry1 is a view, but you're mixing the two formats for PostGIS's DATA line. You can either do: DATA "the_geom from table" (and it must really be a table) or DATA "the_geom from (select uniqueId, the_geom from qry1) as subQ using unique uniqueId using srid=-1" The reason's simple, but not really well documented. Mapserver needs the following to draw: 1) the shape's column 2) the srid 3) a unique ID for the shape If you use the simple table format, it can use the oid of the table as the unique id, and lookup the srid from the OGC standard geometry_columns metadata table. If you use a view, you need to specify the uniqueID and the srid, because the view doesn't have an oid (unless you pull it from another table) and isn't listed in the geometry_columns table.

I have been struggling with projection, extents, and size for a couple of days now. When I zoom in to a map, the four corner points of my rubber-band box are the new corners for the data displayed in my 400x200 browser space. So, if I define an area that is 2:1 in x size to y size, I zoom in as expected. But when defining space that is not this 2:1 rectangular ratio, the data gets stretched/contracted/distorted to fit that space, because the corners of my new definition become the drawn corners, instead of extra data in either the x or y direction being used to fill the the remaining area. Previously, interfacing to mapserver 4.0.2 on a Windows platform worked just fine. Currently, interfacing to mapserver 4.4.1 on a Red Hat Enterprise server shows these symptoms. I changed NONE of the html, js, or java, except all I did was point to a new url with the linux mapserv, and the corresponding new location for the .map file. Is there a platform-dependency I am not worrying about correctly? Is there a version-dependency I am not worrying about correctly? Perhaps the answer is to point me at the correct discussion thread dealing with these issues? I couldn't find anything useful after a few searches, so thought I would send out a post while I'm still looking. Thanks!

As he mentioned, I use the C preprocessor to manage the generation of .map files. The use of #define and #include directives is especially helpful when you have a large number of attributes you want to keep consistent across layers. For example, I might have a "street map" that's made up of several different LAYERs (interstate highways, state highways, local roads, etc., etc.). Each of them might have labels using fonts of a particular style and size. If I use a statement like: #define STREETFACE "Arial" #define STREETSIZE 10 Then it's easy for me to change the typeface or size of all those layers at once, keeping them consistent. - Ed Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 Phone: +1 (978) 251-4242 Fax: +1 (978) 251-1396 ed at topozone.com -----Original Message----- From: UMN MapServer Users List [mailto:MAPSERVER-USERS at LISTS.UMN.EDU] On Behalf Of Stephen Woodbridge Sent: Wednesday, April 20, 2005 5:39 PM To: MAPSERVER-USERS at LISTS.UMN.EDU Subject: Re: [UMN_MAPSERVER-USERS] consolidation of .map file contents Dylan Beaudette wrote: > Steve, > > Thanks for the input.

You can simply copy the ones from your c:\windows\fonts directory, or go to any of the font websites out there. (You may want to check the copyrights. Most of Windows' fonts are copyrighted, and I don't know the legality of using them on a server.) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Nacionales) Date: Thu, 21 Apr 2005 00:33:18 -0500 Subject: UNIX Fonts? In-Reply-To: Message-ID: Bob, If you are using the core Microsoft fonts (arial, times new roman, courier new, verdana, etc.) then you can copy those fonts to your Unix machine. You might want to have a look at Microsoft's license on the use of their fonts. I don't know about the licenses of any other Windows truetype fonts so you also might want to go back and read them before you make copies. In general, many of these licenses only prevent you from modifying the fonts and/or selling them--no problem since you're only using it to display labels. There are some free (I'm using the word loosely) fonts that you can use on Unix/Linux--Bitstream has the Vera fonts which is used by Gnome (http://www.gnome.org/fonts/), SIL International has Gentium (http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&item_id=Gentium_download), Bigelow and Holmes has the Luxi fonts, and there are others. The use of truetype fonts in MapServer is the same for Windows as for Unix/Linux and Mac. You don't need to install them on a system directory (e.g. /usr/share/fonts c:\windows\fonts) but you can put them in some other directory along with your MapServer font list (see http://mapserver.gis.umn.edu/fontset.html).

Kind Regards Gail Hi Gail, I tried the following request on your server http://camber.mc.man.ac.uk/cgi-bin/mapserv.exe?map=c:\Inetpub\wwwroot\MIMAS\wcs_mimas_mosaic.map&SERVICE=WCS&REQUEST=GetCoverage&Coverage=Landsat7Mosaic15m&FORMAT=ECW&BBOX=-8,50,-6,52&CRS=EPSG:4326&WIDTH=2000&HEIGHT=2000 and I got an ECW image back which I checked with gdalinfo and it look ok, but looking with openev the image was blank!! With your request I get the same error as you. I guess it is an error with your setting up of the bounding box in the map request. There is an open bug against the WCS (correct me if I am wrong) that when you do a reprojection of an image causes the image to be black (quite amusing when translating DEMS!!). If you can sort out the following in the describeCoverage (created from the map file) 0 0 700005 1.05e+006 I think you will be fine. Interesting that you are doing a Landsat WCS here in the UK (there are a couple now), any chance you can drop me a line telling me about it? thanks, Norman Barker From bobbyfung at HOTMAIL.COM Thu Apr 21 05:43:36 2005 From: bobbyfung at HOTMAIL.COM (Libo Feng) Date: Thu, 21 Apr 2005 07:43:36 -0500 Subject: Create a shapefile using Java Mapscript Message-ID: I am a newbie to Java mapscript and in my project, I need to dynamically create a shape file that contains a point.

Message-ID: I originally posted this under a reply to a problem with distorted maps. This is the same text, under a new subject with version and platform dependency type words: I have been struggling with projection, extents, and size for a couple of days now. When I zoom in to a map, the four corner points of my rubber-band box are the new corners for the data displayed in my 400x200 browser space. So, if I define an area that is 2:1 in x size to y size, I zoom in as expected. But when defining space that is not this 2:1 rectangular ratio, the data gets stretched/contracted/distorted to fit that space, because the corners of my new definition become the drawn corners, instead of extra data in either the x or y direction being used to fill the the remaining area. Previously, interfacing to mapserver 4.0.2 on a Windows platform worked just fine. Currently, interfacing to mapserver 4.4.1 on a Red Hat Enterprise server shows these symptoms. I changed NONE of the html, js, or java, except all I did was point to a new url with the linux mapserv, and the corresponding new location for the .map file. Is there a platform-dependency I am not worrying about correctly? Is there a version-dependency I am not worrying about correctly? Perhaps the answer is to point me at the correct discussion thread dealing with these issues? I couldn't find anything useful after a few searches, so thought I would send out a post while I'm still looking. Thanks!

Brian, As I understand it, the problem you are seeing is that MapServer used to expand the region you requested as needed in order to ensure square pixels, and now does not resulting in distorted results, is that right? Indeed, for MapServer 4.4 there was "nonsquare" support added to MapServer. In WMS mode this is on by default, in order to comply with the specification. In non-WMS mode it is supposed to be off by default (giving you the traditional aspect preserving behavior) unless you add the following line to your .map file: CONFIG MS_NONSQUARE YES Is your client requesting data via WMS? If so, then you will pretty much have to pre-adjust your bounding box to match the aspect ratio of the image size. If you are getting this behavior in traditional MapServer cgi mode and haven't defined MS_NONSQUARE then we should look into what is going on.

Since MapServer does not know the pixel resolution of your screen, it cannot know how many pixels are used to create "one centimeter on screen". That's what the RESOLUTION statement in the map file does; the default value is 72 for 72 pixels per inch (the units are always pixels per inch). Since you cannot know the user's screen resolution either, you can either work with this estimate or choose another guess of your own. Most users are running monitors more in the 100 pixels per inch range these days. - Ed Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 ed at topozone.com (978) 251-4242 -----Original Message----- From: UMN MapServer Users List [mailto:MAPSERVER-USERS at LISTS.UMN.EDU] On Behalf Of Trond Michelsen Sent: Thursday, April 21, 2005 10:39 AM To: MAPSERVER-USERS at LISTS.UMN.EDU Subject: Re: [UMN_MAPSERVER-USERS] wms capabilities and mapfile scale correspondence On Thu, Apr 21, 2005 at 10:32:56AM -0400, Daniel Morissette wrote: >> The problem is that they display different values... :s In the map >> file I have >> MINSCALE 45000001 >> MAXSCALE 999999999999 >> and in the capabilities file this same layer has >> Any idea why? >> Maybe a unit related issue?

The best way of doing this is through Javascript. I've thrown a small sample of this in action at http://www.houseclick.com/map.htm It uses a small piece of JavaScript which keepts track of the map URL, as well as the current map size, current extent, and even can toggle a map layer on and off. All options are stored in JavaScript variables, and wheenever an option is changed, the new URL is reconstructed using the variables and the image is updated. The map URL is actually just the path to the MapServer CGI, plus with some MapServer options passed using CGI variables. The key CGI variable to use here is the "mode" variable-- set it to "map" to have the MapServer CGI spit out just a map image. For instance, the URL http://www.houseclick.com/cgi-bin/mapserv?mode=map&mapext=- 9561082+4629954+- 8761082+5429954&map=/var/www/map/map.map&mapsize=400+400&layer=roadtrl020&l ayer=states spits out just a map image : with an extent of -9561082,4629954 to -8761082, 5429954 using the map file located at /var/www/map/map.map with a size of 400 width by 400 height with layers "roadtrl020" and "states" turned on . It's really quite simple.

Message-ID: Frank, Thanks for your reply. Yes, you understood my problem correctly. Now, I am trying to understand your response ..... I AM making wms requests, and if I understand your comments correctly, I have to "pre-adjust my bounding box to match the aspect ratio of the image size" .... not sure what this means ...... To avoid this, do I add an entry to my map file like: CONFIG MS_NONSQUARE NO or CONFIG MS_NONSQUARE FALSE ? Or, do I really have to resize the browser display area each time I select a new area of new x/y shape? The original image dimensions, on which I am zooming on, are 10020 x 5010. In my map file, I have an entry for SIZE 500 250 and corresponding width and height specifications in my url call to mapserv. I added the CONFIG MS_NONSQUARE NO entry to the map file, with no effect. I usually assume it is always my fault, so I am not ready to blame mapserver yet. Any hints you can provide would be greatly appreciated. Maybe I can tar up my entire web site, send it to you, go on vacation, have you fix everything while I'm gone, then take credit for it when I get back?????!!!!!! :) Brian.

Brian, You cannot override MS_NONSQUARE in WMS mode. The GetMap request forces it on for WMS protocol compliance. Basically what I am suggesting is that you either need to adjust your BBOX to have the same aspect ratio as your WIDTH/HEIGHT or you need to adjust the WIDTH/HEIGHT of your request. To get the old behavior, you would need to expand the BBOX extent in one dimension or the other till you get the same aspect ratio as the image being requested. The following C code from MapServer essentially does this calculation. You may want to adapt this approach.

Nuno, I don't have any particular idea what is going wrong. From the debug messages it is getting reasonably far. Under normal conditions I think that would be the last debug messages though, so it is hard to judge how much further it got. In particular, there is no "exiting" message despite what might be implied by the word entering message. I would suggest trying to replicate the request at the command line and see how that goes. ie. ./mapserv QUERY_STRING='map=wcs.map&SERVICE=WCS&REQUEST=GetCoverage&COVERAGE=landsat_europe&CRS=EPSG:4326&BBOX=-6,40,-5.5,40.5&RESX=0.00027778&RESY=0.00027778&FORMAT=geotiff' If the problem persists try to boil down the problem and submit a bug report via bugzilla (or debug it yourself).

I'd like to display images on my maps next to the features they go with. Basically, I have a set of points in a postgis database with an attribute which is a URL to a JPG (I can convert them to PNG or anything else). They are mostly about 337x394 pixels. Some are up to double that - I can resize them to match if needed. I have the images on another machine accessible via http, and I'd like to leave them there since they update via a separate process. (I have a caching script setup w/Apache so only the first fetch will go over the network.) So, I considered using GDAL's Virtual support, but I don't know if it needs local images, and I think it needs GeoTIFFs or the like: these are just plain images. I also considered updating the mapserver code to use a different image for each shape. However, those filenames are local as well, so I'd have to add code for fetching them image via libcurl. Generally, I don't see a simple solution. Perhaps I could write a GDAL Dataset that will fetch images from a URL on demand? Any thoughts would be appreciated, Bill From fwarmerdam at GMAIL.COM Thu Apr 21 12:09:54 2005 From: fwarmerdam at GMAIL.COM (Frank Warmerdam) Date: Thu, 21 Apr 2005 15:09:54 -0400 Subject: Mapserver for Windows 2003 + FCGI + SDE In-Reply-To: <4267F596.7020500@refractions.net> Message-ID: On 4/21/05, Mark Leslie wrote: > I'm making WMS requests.

Mark, I'm sorry, I can't see why the error messages would still pile up in this situations. You might want to add some printfs() to verify things are happening as expected. The key in mapserv.c is this bit: #if defined(USE_WMS_SVR) || defined(USE_WFS_SVR) || defined(USE_WCS_SVR) if ((status = msOWSDispatch(msObj->Map, msObj->request)) != MS_DONE ) { /* This was a WMS/WFS request... cleanup and exit * At this point any error has already been handled * as an XML exception by the OGC service. */ msFreeMapServObj(msObj); #ifdef USE_FASTCGI /* FCGI_ --- return to top of loop */ msResetErrorList(); continue; #else /* normal case, processing is complete */ msCleanup(); exit( 0 ); #endif } #endif /* have an OWS service request */ Basically, msOWSDispatch() will return something other than MS_DONE if it finds it has received a WMS, WFS or WCS request. Then the code should call msFreeMapServObj(), msResetErrorList() and then continue back to the main dispatch loop. msResetErrorList() should wipe the current error stack. Either in a debugger, or with lots of printfs(), verify that all these stages are working as expected.

In response to your questions: 1. No JS errors 2. Was using Konqueror on Linux (KDE 3.3) 3. I can view the legend on the UMN site... but only with Firefox ... so my first problem, was that Konqueror was not rendering anything. Switching to Firefox allowed me to see the legend on the UMN site. However, on my test site, the legend appears to be a binary dump of a png image... you can see this first hand here: http://169.237.35.250/~dylan/mapserver/dhtml/landview_dhtml_x.html thanks, -- Dylan Beaudette Soils and Biogeochemistry Graduate Group University of California at Davis 530.754.7341 > Dylan, > > I haven't used the legend so far myself, but I know it uses the XMLHttp > technique.

The Sol Katz Award for Geospatial Free and Open Source Software (GFOSS) will be given to individuals who have demonstrated leadership in the GFOSS community. Recipients of the award will have contributed significantly through their activities to advance open source ideals in the geospatial realm. Sol Katz was an early pioneer of GFOSS and left behind a large body of work in the form of applications, format specifications, and utilities while at the U.S. Bureau of Land Management. This early GFOSS archive provided both source code and applications freely available to the community. Sol was also a frequent contributor to many geospatial list servers, providing much guidance to the geospatial community at large. Sol unfortunately passed away in 1999 from Non-Hodgkin's Lymphoma, but his legacy lives on in the open source world. Those interested in making a donation to the American Cancer Society, as per Sol's family's request, can do so at https://www.cancer.org/asp/donate/don_multi_donate.asp?navToScreen=don_1. Nominations for the Sol Katz Award should be sent to sol.katz.award at gmail.com with a brief description of the reasons for this nomination. Please place "Sol Katz Award" in the subject of the email. Nominations will be accepted until Saturday April 30th @ midnight. A recipient will be decided from the nomination list by a selection committee. The winner of the Sol Katz Award for Geospatial Free and Open Source Software will be announced at the Open Source Geospatial conference in June. The hope is that the award will both acknowledge the work of community members, and pay tribute to one of its founders, for years to come. -- Organizing Committee Open Source Geospatial '05 http://mapserver.gis.umn.edu/mum/mtg2005.html From dylan at IICI.NO-IP.ORG Thu Apr 21 14:48:44 2005 From: dylan at IICI.NO-IP.ORG (Dylan Beaudette) Date: Thu, 21 Apr 2005 14:48:44 -0700 Subject: changing DATA parameter in mapfile via URL Message-ID: Is is possible to change the 'DATA' parameter via a URL-style variable such as: ...&map_layername_data="xxx.shp" i am able to change every other property of this layer, but not its data source. if this is not possible, does anyone know of some kind of work-around? i am trying to use a single map file for numerous different shape files... thanks in advance! -- Dylan Beaudette Soils and Biogeochemistry Graduate Group University of California at Davis 530.754.7341 From steve.lime at DNR.STATE.MN.US Thu Apr 21 14:56:35 2005 From: steve.lime at DNR.STATE.MN.US (Steve Lime) Date: Thu, 21 Apr 2005 16:56:35 -0500 Subject: changing DATA parameter in mapfile via URL Message-ID: For security reasons we don't allow that by default. You have to set the DATAPATTERN parameter in the mapfile first. The pattern is nothing more than a regular expression that will limit the values that DATA can take. For example: DATAPATTERN "xxx|yyy|zzz" will allow ...&map_layername_data=xxx.shp but not ...&map_layername_data=sss.shp. Another option is using runtime substitutions. In your layer definition you'd have something like: LAYER DATA %thefile% .... END and then you'd set a CGI variable called 'thefile' to hold the name of a shapefile. If you do the whole filename as just a single variable you have the hole that DATAPATTERN was put in place to plug. You'd probably want to use the %thefile% as part of a longer file name instead which would be moderately safe.

For example a layer set to show all X's within 100m of Y could be reset by the user to find all X's within some other distance of Y, or another function could be used, such as all X's contained by Y where attribute Z=foo. ... or whatever type of spatial / attribute query you need so long as it doesnt bog your server down in processing. Using javascript or an ASP redirect (or whatever your choice of method) to parse the appropriate string into your "&thefile=xxxxx" variable in the URL. or the form submission. It adds some real GIS abilities to mapserver without very much effort. Cheers, Ken Lord Vancouver BC On 4/21/05, Steve Lime wrote: > For security reasons we don't allow that by default.

The BUFFER value tells how many pixels you want to be between two symbols, and the MINDISTANCE value tells how many pixels you want between instances of the same symbol. So if you set: BUFFER 5 MINDISTANCE 300 You will see at least 5 pixels separating two symbols in that layer, and you will see at least 300 pixels between instances of the same symbol... by instances of the same symbol I mean for example if you are labeling streets, you won't see a particular street name twice right next too each other, there will be at least 300 pixels between the two istances of that street name.

Chris, The GDAL source distribution includes a tigerpoly.py script that will form polygons from tiger data. Basically the issue with TIGER data via OGR is that OGR gives a very literal view of the tiger data and you need to form the polygons yourself. http://www.gdal.org/srctree/pymod/samples/tigerpoly.py I understand Schyuler (author of Mapping Hacks: http://mappinghacks.com) has also written a similar script that loads the data into PostGIS and does some additinoal transformations on it.

You've got multipolygon states and their order in the shapefile is influencing which part gets labeled. If this is the case you have a couple of options: 1) Turn the multiple polygons into one multipart polygon for each state (except for perhaps Michigan). That way you can only get one label/state. Doing so will require a desktop tool (like arcview) but could also be done using MapScript. 2) use sortshp to sort your shapefile based on area (hopefully you have an area or some size related attribute) in ascending order. This will cause labels for the larger polygons to get priority when labeling (last on the map is labeled first). When combined with MINDISTANCE only the largest part should get labeled. Steve >>> Mark Dieterich 4/22/2005 11:16:53 AM >>> Hi everyone, I'm trying to use the generalized national atlas data at high zoom levels for my maps. It's working out pretty well, until I get to a zoom level where all I want to display is state names. Two problems: 1) I only want each state name to display once. I can put a really big MINDISTANCE in my mapfile to handle this, but it introduces the next problem. 2) Where mapserver chooses to put the label appears to be random. I'm sure it's not, but it certainly isn't the center of the state. Any idea how I can work around these two issues?

Since the streets data is huge, it is failing to load hence i need to filter the streets data. So i was looking for a solution to fetch and display only street data relevant for the visible region of the map. Can you pls. let me know how to achieve this? Also, i have a dropdown of city with the FIP as the value and i want the map to move to the city location based on user choice. How do i achieve this? Do i use filter or expression, as i'm already using an expression as '[TYPE]' eq 'city' but when i change it to say '[PL_FIP]' eq '00884' nothing comes up, why is it so? Just wanted to let you know that i'm generating the map by querying a dynamic layer with some location content. Any direction would be very helpful, as there are no advanced php mapscript example.

Have you actually processed the vectors into an orthographic projection? If not, you should set the layer projections to (I assume, after looking at your map image) a latlong projection. After doing that, let's see if the starburst problem remains. It may ... see the image at the bottom of http://zcologia.com/news/16 for an example of failure to properly deal with a graticule for an orthographic projection. cheers, Sean -- Sean Gillies sgillies at frii dot com http://users.frii.com/sgillies From covariance at SHAW.CA Fri Apr 22 18:24:16 2005 From: covariance at SHAW.CA (Bob Bruce) Date: Fri, 22 Apr 2005 20:24:16 -0500 Subject: UNIX Fonts? Message-ID: I got this explanation from my hosting provider today about how he fixed the font problem on his system: "Hey Bob. Well really, the final solution it isn't that complicated, it was getting to that point that took a lot of messing around. Basically, if you want true type support in PHP/Mapscript you have to have freetype support compiled into PHP. And the only way to get freetype support in PHP is to compile freetype into GD and then compile GD into PHP. Normally you add GD support to PHP with a simple option (--with-gd) and PHP compiles in GD which is included with the PHP distribution. Thats easy except the version of GD which comes with PHP doesn't include freetype. So you have to download and compile GD separately which really shouldn't be that big of a deal except if you want GD to have freetype you have to download and install that first as well! And it also requires a number of other libraries to be installed first (libjpg, libpng, libXpm etc.) The big problem there as that Xpm is old and it won't compile with out a very special compiler (which I don't have). So, in this case I would normally rely on a binary package that comes with the OS (Slackware 9.1 in this case). But, Xpm is only available by installing the entire XWindows system (XFree86). My server doesn't have any need for Xwindows and since its such a large package I didn't really want to install that but I did it anyhow. Unfortunately there was something wrong with the Xpm libraries. Perhaps they might have been the wrong version. I'm not sure. Ultimately I found a binary distribution of just Xpm. I think that allowed Xpm to compile into GD but then when I tried to start PHP it would throw an error complaining about Xpm and die. Finally I gave up on Xpm support and managed to compile GD without it. Then, PHP wouldn't compile anymore but it turned out I had to remove the "--with-xpm" option from PHP's configure and do a "make clean". Finally PHP compiled and I was able to get it installed and Apache started without it complaining. I think there were several other false paths I went down as well but I've forgotten them." this gave me a greater appreciation for the work involved in setting up UNIX servers and I'm glad that someone else is looking after that for me right now. Anyway I copied the basic TTF files from my Windows system, including one that I made up of the Trans-Canada highway symbol, and they are drawing quite nicely now.

The "starburst" effect is quite odd. It looks like some vertices are "at" 0,0 for some reason. I would suggest: o trying using an OGR connection type in you mapfile, to see if there is some quirk reading your shapefiles with the builtin mapserver code. o If that produces the same results, inspect your dataset with ogrinfo and see if there is anything odd about the vertices. Ideally reviewing a polygon you know is causing problems like Maine. Other points: o As Sean notes, it is hard to believe your data is really in an orthographic projection. If your shapefile is really in geographic latlong then you should declare it appropriately in your mapfile (+proj=latlong +datum=NAD83). o You declare your state and country layer projections without any lat_0, or lon_0 values. This is dangerous because internal defaults will be used and these can be hard to predict. I imagine MapServer is trying to reproject the vectors between two ortho projections but I doubt that is what you really want to happen. > Our current approach is to generate the lines with MMS, and then use a > separate step to merge the data (satellite image) with the outlines image, > and produce the composite image seen in the above URL.

I cannot get the image to center when I click on the image and with some zooming factor. I am using image coordinates (not geographical coordinates) for zooming. 1.)Can anyone think of possible reasons? I can provide with any necessary information. 2.) Also, how do I center the image based on my click without zooming? 3.) Finally, does the extent of the map automatically changed by mapscript, when I zoom? I hope, i can get this resolved!

The question has changed. NOW, I need to know this: Why, when I try to instantiate a map object with any map file other than "" do I get a segfault? v---snip--- #!/usr/bin/perl -w use mapscript; use XBase; my $mapObjFull = new mapscript::mapObj("itasca.map"); warn "Got Here 2.5"; ^---snip--- This gives me a segfault. The itasca.map file is the one found in the mapserver demo "workshop." If I call new mapscript::mapObj with no map, it works fine: v---snip--- #!/usr/bin/perl -w use mapscript; use XBase; my $mapObjFull = new mapscript::mapObj(); warn "Got Here 2.5"; ^---snip--- Will produce the message "Got Here 2.5 at line 6" or something like that. It works fine. Just to rule out the idea that itasca.map had a layer or something that it couldn't access (though it works fine in the workshop demo), I made a copy of it and commented out ALL layers. It still segfaults. In desperation I used the helloworld map from the tutorials thinking I could avoid any issues with non-existent data layers etc. It still segfaults. Someone mentioned looking for libmap.a and see if it is an old version. I don't have libmap.a in any library path. Yet, the old files for perl mapscript work perfectly. It's the new ones that don't. What am I missing here? It isn't the map files. It's something about the perl mapscript build. I am trying to do all of this with Mapserver 4.4.1 or 4.4.2.

I *think* I resolved it by doing a clean build (or by manually removing all newly created .obj and .lib files). I was using the MS SDK's to compile. If that doesn't solve it, I guess try checking if the path where mapserver_i.lib is created, exists in your LIB path (check your LIB path settings in the batchfile, if using one. I have had to modify it). Also, be careful with using backslashes in paths. In some rare situations, they are treated as special 'escape' characters. I tend to change them to forward slashes (which the VC compiler seems to handle just fine) and I try to make sure there are no spaces in my paths. regards, Jacob -----Original Message----- From: UMN MapServer Users List To: MAPSERVER-USERS at LISTS.UMN.EDU Sent: 4/23/2005 4:57 AM Subject: [UMN_MAPSERVER-USERS] Trouble with compiling 4.4.2 under MSVC++ I am trying to compile MS 4.4.2 under MSVC++ and I get the following output from nmake /f makefile.vc C:\mapserver_build\mapserver-4.4.2>nmake /f makefile.vc Microsoft (R) Program Maintenance Utility Version 6.00.8168.0 Copyright (C) Microsoft Corp 1988-1998.

I have had to modify it). Jacob / Donnie, The Makefile.vc for MapServer on win32 didn't properly express the dependencies of the exes on the DLL properly so if something went wrong linking the DLL you had to manually delete mapserver.lib to force the right things to get rebuilt. I have corrected this in 4.5 CVS. In the meantime, those using 4.4 may have to delete mapserver.lib to force things to rebuild properly, or do a "nmake /f makefile.vc clean".

Maybe somebody can confirm or disagree my conclusions and answer some questions? * I have to specify the coordinate system for every data source? - At least for shapefiles and postgis layers the coordinate system should be "embedded"?

But the reference system is getting important if i want to calculate the absolute position of a point in 3d space because the associated height value is based on the surface of the reference ellipsoid? * There are data sources available which does not have a reference system at all and consists of "pure" lat/long data? - If i specify a reference system in the mapfile for such data anyway, the positions of this data source are asumed to be flat on the surface of the specified reference ellipsoid? * To do a projection (like lcc) it is absolutely necessary to have a reference system, because it's necessary to know the 3d positions of all data to perform the projection? - Does mapserver consider the height of any point over the surface of the reference ellipsoid for projection? Probably this is done by proj4 lib anyway. Does it? Is it necessary? * If i specify a latlong output projection and the source data is also in latlong althought there is a reference system specified like NAD83, there is no reprojection done? - Is this faster than output to lcc for example? - Isn't it totally regardless of which reference systems are specified in this case? * The map EXTENTS specified in the mapfile are always related to the result of the output projection? - For lcc they are in meter, for latlong they are in decimal degrees? - In the lcc projection it is quite easy to set the origin of the map by lat_0 lon_0 parameter if i want to zoom to a specific lat/lon position having always the same extents. + Is this the usual way? With lat/long output, the only way to change the origing is changing the EXTENT? - If i set k != 1 for lcc, the scale calculation goes wrong? So zooming should always be done be modifing the map extents? Is the k parameter useful in mapserver anyway? * The SIZE and RESOLUTION paramter in mapfile are used to calculate the real size of the displayed image. The specified map EXTENT is fitted into this "window". Mapserver does not really know about the units of the output projection. Therefore i have to specify the UNITS in the mapfile. With a projection output in meter, the scale can be calculated now. Based on the scale and the resolution, the scalebar is generated. - The documentation says, the scale is "Set most often by the application." Is this really true? I don't know how to set it and i thought it should be calculated by the mapserver itself? - How is it possible for mapserver to calculate a scalbar for lat/long output? I thought it should be even for projections difficult to calculate a scalebar. Isn't it only correct for parts of the map because of distortions? I thought this problem would be even more difficult for unprojected maps? Is this only a rough estimation? * What happens if there is projected INPUT data with units in meters for example? I think it should work too if i specify the correct projection. But is it internally "inverse" projected to latlong coordinates to merge it with other data sources which are maybe naturally in latlong coordinates and then reprojected to the output projection?

For those logical expression it currently states: Logical expressions allow you to build fairly complex tests based on one or more attributes and therefore are only available with shapefiles. Logical expressions are delimited by parentheses "(expression)". Attribute names are delimited by square brackets "[ATTRIBUTE]". These names are case sensitive and must match the items in the shapefile. For example: EXPRESSION ([POPULATION] > 50000 AND '[LANGUAGE]' eq 'FRENCH') ... The following logical operators are supported : =,>,<,<=,>=,=,or,and,lt,gt,ge,le,eq,ne. As you might expect this level of complexity is slower to process. Here one should add "=~" to the supported operators. Stefan. > -----Urspr?ngliche Nachricht----- > Von: Armin Burger [mailto:armin.burger at gmx.net] > Gesendet: Sonntag, 24.

My extents were wrong as IMGEXT do not match the gdalinfo info fo upper-left, lower-right style when applied to Australia. Seems I have to switch the latitude. Ok, so just to finish up this thread, found a solution by taking a point using Mapxy and then applying a scale or buffer. The rasters I am using have a pixel size of (1.26956817,-1.26956817) and a unit of 0.0174532925199433. By matching the scale as returned in the template/html file, as close as possible to this pixel size shown by gdalinfo, the maps start looking pretty good as they have little or no scaling. First question: With a given pixel size and unit (metres) above, what is the formula to work out the scale to input? In the example above, I found a value of .31267 would give me a matching output scale to pixel size to 4 decimal places. Second question: Loading the TIF file up in Apple Preview, it looks jagged for a moment, until it anti-aliases the file. Once anti-aliased, the legibility improves noticeably. I take it mapserver cannot perform any anti-aliasing when scaling rasters. I suspect even nearest neighbour would be a great improvement. Any plans for this?

The MINSCALE and MAXSCALE values are the denominators of scale ratios, like 1:10,000 scale. MINSCALE 10000 means "a minimum scale of 1:10,000", where one meter on the map equals 10,000 meters on the ground. The problem becomes, "what's one meter on the map"? The RESOLUTION statement answers that question. The default value is 72, meaning that 72 pixels in a MapServer output image are presumed to occupy one inch on the screen. This is actually unlikely to be an accurate value unless you're running a 20-year-old Macintosh, but it often doesn't matter - it's mostly used for internal calculations. So, if 72 pixels are presumed to cover one inch on the screen, and your image has a source resolution of 1.26956817 meters per pixel, then one inch on the screen will show 72 * 1.26956817 meters or 91.40890824 meters of image. Since 91.40890824 meters equals 3598.7687 inches, this means one inch on the screen shows 3598.7687 inches on the ground - a scale ratio of 1:3598.7687 If you displayed that image at the "scale" of 3598.7687 you should get a pixel-for-pixel replica of your source image. If you use a different RESOLUTION statement, you need to adjust accordingly. For calculating the IMGEXT values, you simply need to make the X extent and Y extent equal the number of (X or Y) pixels in the image times 1.26956817. Yes, there are better-quality ways of resampling images, but - as you saw in Preview - they're slow. MapServer doesn't use them, but you can use various tools (including gdalwarp, from the GDAL distribution) to resample images offline and create "pyramids" of varying resolutions. This will improve the display quality of your images while keeping the performance fast - at the expense of extra disk space and preprocessing work. - Ed Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 Phone: +1 (978) 251-4242 Fax: +1 (978) 251-1396 ed at topozone.com ________________________________ From: UMN MapServer Users List [mailto:MAPSERVER-USERS at LISTS.UMN.EDU] On Behalf Of Nick Dabner Sent: Sunday, April 24, 2005 7:17 PM To: MAPSERVER-USERS at LISTS.UMN.EDU Subject: Re: [UMN_MAPSERVER-USERS] Zooming to match a raster scale Got it. - Thanks Bart.

I'm not going to try to give you a complete GIS tutorial, but you should try to get one. Try to learn about datums, projections, etc. OUTSIDE of MapServer, then learn how to use those concepts INSIDE MapServer. That way you're not trying to do two things at once, and you might be able to ask questions in the most appropriate places. For example, there is a separate mailing list for PROJ and that's the best place to ask questions about it. If all the input and output data in a MapServer map use the same coordinate system, then you do not have to specify any coordinate system at all. If that is not the case, you should really specify ALL input AND output coordinate systems. Coordinate systems are not "embedded" as often as you seem to think - you need to specify them. WGS84 and NAD83 can be treated as identical - for the portion of the globe where NAD83 is defined. Do not try to use coordinates in Mozambique and call them "NAD83". Yes, the "geographic" coordinate system refers to longitude/latitude coordinates. Longitude and latitude are NOT "always the same" and must be expressed relative to a datum; 30 degrees North, 90 degrees West is NOT the same location in the NAD27 datum as it is in NAD83. WGS83 and NAD83 are datums - they are not coordinate systems. Cartographic coordinate systems are based on datums. If you have "pure" (most people would say "unprojected") longitude/latitude data you still need to know what datum is used. You're worrying too much about height/altitude - ignore it. The ellipsoid/datum parameters for your projections know how big the Earth is (or at least, how big it is defined to be for that ellipsoid). If the output and input projections are identical there is no reprojection done. Yes, this is faster, but vector reprojection is VERY fast and not worth worrying about (at least, not now). The map EXTENTS are expressed in the units of the output projection being used by MapServer (as defined in your MAP file). You will have MUCH better luck getting answers if you limit your postings to one or a few related questions. Long laundry lists of questions tend to make readers (a) feel they don't have time to answer all those questions and/or (b) don't know how to answer ALL of them, so they might as well not answer ANY of them.

My problem is that they use a datum that I haven't seen before "HPGN". Here is the projection info from their metadata: MAP PROJECTION PARAMETERS: Projection ALBERS Units METERS Datum HPGN Spheroid GRS1980 1st standard parallel 24 0 0.000 2nd standard parallel 31 30 0.000 Central meridian -84 0 0.000 Latitude of projection's origin 24 0 0.000 False easting (meters) 400000.00000 False northing (meters) 0.00000 After some looking around, and some advice from the board a few weeks ago, I used these projection instructions in Mapserver (CVS Head): PROJECTION "+proj=aea" "+lat_1=24" "+lat_2=31.5" "+lat_0=24" "+lon_0=-84" "+x_0=400000" "+y_0=0" "+ellps=GRS80" "+datum=NAD83" "+units=m" "+no_defs" END It seemed the "NAD83" was close enough to the "HPGN" datam. Now I'm seeing small problem when combining any of the data from this source with others that are in the Florida West projection (espg:26759), and I'm suspecting that the bad datum is the problem. Actually, I'm hoping that's it because if it is, I'm confident someone here can help me get it right: if not, it means the data's bad :-( An example of the "wrongness" can be seen at: http://www.binko.net/badProj.png The roads should line up within the parcels.

Mikkelsen) Date: Sun, 24 Apr 2005 21:56:42 -0700 Subject: HPGN Datum? In-Reply-To: Message-ID: Hi Bill, Here is some information for you about HPGN and HARN. HPGN and HARN HPGN (High Precision Geodetic Network) and HARN (High Accuracy Reference Network) are synonymous. They are both names for the same project that is focused on readjusting the NAD83 datum to a higher level of accuracy state by state. HARN/HPGN is more accurate form of the North American Datum. What you are experiencing in Florida is that network of points that defines the HPGN/HARN is based on NAD83, but that local states often try to make denser grids and hence come up with better transformation parameters. The EPSG data model does incorporate the HARN information for Florida - based also on the SPCS zones. Looking at the files found in the PROJ.4 library, it appears as though the code you are using epsg:26759 is based on NAD27. This is where I would say the problem is occurring. If you use epsg:26959 this should solve the problem and will match with the HARN/HPGN. Cheers, Dean Dean C. Mikkelsen,B.Sc.,P.Eng.

Hi everyone, I found an excellent site for Florida map data: http://www.fgdl.org/ Some of their data is a bit out of date, but there is a nice selection, and it's all in the same projection, even from a wide variety of sources. My problem is that they use a datum that I haven't seen before "HPGN". Here is the projection info from their metadata: MAP PROJECTION PARAMETERS: Projection ALBERS Units METERS Datum HPGN Spheroid GRS1980 1st standard parallel 24 0 0.000 2nd standard parallel 31 30 0.000 Central meridian -84 0 0.000 Latitude of projection's origin 24 0 0.000 False easting (meters) 400000.00000 False northing (meters) 0.00000 After some looking around, and some advice from the board a few weeks ago, I used these projection instructions in Mapserver (CVS Head): PROJECTION "+proj=aea" "+lat_1=24" "+lat_2=31.5" "+lat_0=24" "+lon_0=-84" "+x_0=400000" "+y_0=0" "+ellps=GRS80" "+datum=NAD83" "+units=m" "+no_defs" END It seemed the "NAD83" was close enough to the "HPGN" datam. Now I'm seeing small problem when combining any of the data from this source with others that are in the Florida West projection (espg:26759), and I'm suspecting that the bad datum is the problem. Actually, I'm hoping that's it because if it is, I'm confident someone here can help me get it right: if not, it means the data's bad :-( An example of the "wrongness" can be seen at: http://www.binko.net/badProj.png The roads should line up within the parcels. The roads are in HPGN, and the parcels are in espg:26759 Any help would as always be appreciated.

Bob, Could you be a bit more specific about what version of mapserver you are building? You are sure you don't have the implementation of msForceTmpFileBase() in maputil.c? It seems to be in CVS currently. Any chance you tried to use a mapserver 4.5 mapserv.c with 4.4 libraries?

Followed your workings and got what is a near perfect match for another scale. In doing so, I can see how is resolution is used, which was some explanation I hadn't found detailed elsewhere. Kept it at 72 dpi. Yes, preview is slow, but the results are nice. Gdalwarp changes projections if I am not mistaken. Do you mean gdal_translate to create the raster pyramids? Will have to give this a try later today as my rasters do vary, especially with inner-city areas. It loooks like I would supply the output size in pixels (x,y) to get the the desired scale. Definately info like this is helpful for us non-geo-versed. Need this kind of info in the --verbose docs!

Followed your workings and got what is a near perfect match for another scale. In doing so, I can see how is resolution is used, which was some explanation I hadn't found detailed elsewhere. Kept it at 72 dpi. Yes, preview is slow, but the results are nice. Gdalwarp changes projections if I am not mistaken. Do you mean gdal_translate to create the raster pyramids? Will have to give this a try later today as my rasters do vary, especially with inner-city areas. It loooks like I would supply the output size in pixels (x,y) to get the the desired scale. Definately info like this is helpful for us non-geo-versed. Need this kind of info in the --verbose docs!

The MINSCALE and MAXSCALE values are the denominators of scale ratios, like 1:10,000 scale. MINSCALE 10000 means "a minimum scale of 1:10,000", where one meter on the map equals 10,000 meters on the ground. The problem becomes, "what's one meter on the map"? The RESOLUTION statement answers that question. The default value is 72, meaning that 72 pixels in a MapServer output image are presumed to occupy one inch on the screen. This is actually unlikely to be an accurate value unless you're running a 20-year-old Macintosh, but it often doesn't matter - it's mostly used for internal calculations. So, if 72 pixels are presumed to cover one inch on the screen, and your image has a source resolution of 1.26956817 meters per pixel, then one inch on the screen will show 72 * 1.26956817 meters or 91.40890824 meters of image. Since 91.40890824 meters equals 3598.7687 inches, this means one inch on the screen shows 3598.7687 inches on the ground - a scale ratio of 1:3598.7687 If you displayed that image at the "scale" of 3598.7687 you should get a pixel-for-pixel replica of your source image. If you use a different RESOLUTION statement, you need to adjust accordingly. For calculating the IMGEXT values, you simply need to make the X extent and Y extent equal the number of (X or Y) pixels in the image times 1.26956817. Yes, there are better-quality ways of resampling images, but - as you saw in Preview - they're slow. MapServer doesn't use them, but you can use various tools (including gdalwarp, from the GDAL distribution) to resample images offline and create "pyramids" of varying resolutions. This will improve the display quality of your images while keeping the performance fast - at the expense of extra disk space and preprocessing work. - Ed Ed McNierney -------------- next part -------------- An HTML attachment was scrubbed...

Or anyone else that can say - developers that have advance copies of Tiger are probably under NDAs on how things work (tho developers can probably update their software to work on Tiger, they just can't say how). I'll probably be waiting a couple weeks to get and install Tiger, just to see where everyone else has problems. Also depends on when I have time next month - kinda busy. But I'll try to get a binary package as soon as I can. Of course, if the current one works on Tiger, that's less pressure, and good to know. GCC 3.3 vs 4.0 shouldn't be too hard - even now Apple has a way to switch versions, so if there are major problems with 4.0 and MapServer, one can just switch to 3.3 which works. If you have Tiger now, as a non-dev, you're lucky. I heard there was a screwup at some online retailers and they shipped some early. I guess those people that got it early wouldn't have an NDA problem. On Apr 25, 2005, at 1:03 AM, Nick Dabner wrote: > Hi List, > > Wondering if anyone has attempted using mapserver on Mac OS Tiger?

From jms4 at PO.CWRU.EDU Mon Apr 25 08:50:38 2005 From: jms4 at PO.CWRU.EDU (James Sohr) Date: Mon, 25 Apr 2005 10:50:38 -0500 Subject: Path-following labels function (MapScript) Message-ID: As part of a larger project to help implement a high-quality labeling system for MapServer, I've written an alpha-level Mapscript function, label_layer_wpft(), which will draw path-following text labels, returning it as a GD true color image which you can then overlay onto your map image. Here are some sample images of it in action: The good: http://img171.echo.cx/img171/7012/good13fx.gif http://img191.echo.cx/img191/8636/good21nf.gif The bad: http://img152.echo.cx/img152/4066/bad0yq.gif And the ugly: http://img152.echo.cx/img152/2049/ugly3uq.gif To use the function, include it in your main mapscript routine. The format for it's use is as follows: $mylabelimage = label_layer_wpft( MAP, LAYER_NAME, LABEL_FORMAT); where MAP is a map object, LAYER_NAME is a string containing the name of the layer you wish to label, and LABEL_FORMAT is a string containing the format of the label (similiar to the TEXTITEM field in a map file). For instance, to create a label image for a layer called "anno_roads", with labels comprised of the street name (STNAME) and street type (STTYPE) fields, use: $road_labels = label_layer_wpft($map, "anno_roads", "[STNAME] [STTYPE]"); You can then overlay this image onto your map image using the appropriate GD functions. It creates labels for a single layer by performing a query for the current map extent against that layer, and then comparing each result to each class within the layer. It then uses each class's label attributes (such as font, font size, and color) to draw the path-following label. To optimize labeling, the function will automatically combine features with common endpoints and common labels into a single feature. Currently, there are quite a few limiations with this function: First of all, it only recongizes classes within a layer using the CLASSITEM feature only (i.e. each expression must be a regular epxression which is compared to the CLASSITEM). It only uses the class label's font, font size, and font color attributes -- it ignores all of the other label attributes (such as position, background color, border color, antialias, buffer, etc.) The function only does a rudimentary check to see if the label will fit on the feature. Currently, the label is automatically centered along the feature's length, and no collision detection is done with other labels. The font name used in the labeling does not use the map's font file-- hence the font name used for each class must be the actual true-type font filename (without the .ttf). For instance, to label with the font arial bold, use "FONT arialbd" in your map file. Like I said, the function is pretty basic so far... but I plan to make a lot of improvements as time allows. If you make any improvements you'd like to share, or have any questions about the function or how to use it, feel free to let me know.

Hi Morten: I am trying to build PHP MapScript and am getting the same errors. Have you managed to solve this problem?

Message-ID: Hi Remy. Thanks for the help about de print option. Your code looks very well but i have some problems to make it work. I added a print button in my application that opens the printmap.php file, and the code in the other file was added in my gmap.inc.php file. But nothing happend when i click the 'Imprimer' button in the new window. What is supposed to happend? I installed pdflib and a pdf table appears when i execute phpinfo(). I supposed that it means that pdflib is working fine. Probably i need a little explanation of how the code works. What happend when i click the print button in my application and what happend when i click the Imprimer button in the new window. I edited some lines in the checkprint() function but i need to know if i have to edit something else. Thanks again for your help, and i'll be waiting your response. _______________________________________ Yo me registr? en www.costarricense.cr From Ken.Tanaka at NOAA.GOV Mon Apr 25 11:11:07 2005 From: Ken.Tanaka at NOAA.GOV (Ken Tanaka) Date: Mon, 25 Apr 2005 12:11:07 -0600 Subject: global mapping issues with orthographic projection In-Reply-To: <931f8ea9050423075479c4795c@mail.gmail.com> Message-ID: Frank and Sean, Thanks for the prompt replies. I'll let you know how things go in trying other projections and parameters. I'm actually one step removed from the problem--I am assisting someone else on our development team. The projection is a little off, when we set the lat_0 and the lon_0 to 0 and -75 respectively (as that is basically GOES EAST's subsatellite point and i think this is where the orthographic projection for that satellite should be generated from) we get no map at all or any errors.

You should have those anyway and it shouldn't be necessary to convert them to Lat/Long. I get $mapscale using the statement: $mapscale = isset($_POST['mapscale']) ? floatval($_POST['mapscale']) : $maxscale; and I set the post value of mapscale using the following statements: // now set up some web page display values $currentscale = round($map->scale); $char_scale = number_format($currentscale); and this is my code to re-center the draw: } elseif($_POST['mode'] == "recenter" ) { $new_point = ms_newPointObj(); $new_point->setXY(floatval($_POST['mapimage_x']),floatval($_POST['mapimage_y'])); $map->zoomscale($mapscale, $new_point, $map->width, $map->width, $mapRect, $maxmapRect); (notice that I don't change the scale in this call) and this is the code to set the last two values of the above call: if(isset($_POST['mapextent'])) { $extents = explode("+",$_POST['mapextent']); $mapRect = ms_newRectObj(); $mapRect->setextent(floatval($extents[0]),floatval($extents[1]),floatval($extents[2]),floatval($extents[3])); $maxmapextent = $_POST['maxmapextent']; // save this for the hidden form variable } else { // set this for the hidden form variable using the values from the map file $maxmapextent = $map->extent->minx . "+" . $map->extent->miny . "+" . $map->extent->maxx . "+" . $map->extent->maxy; } if(isset($_POST['maxmapextent'])) { $maxextents = explode("+",$_POST['maxmapextent']); $maxmapRect = ms_newRectObj(); $maxmapRect->setextent(floatval($maxextents[0]),floatval($maxextents[1]),floatval($maxextents[2]),floatval($maxextents[3])); } hopefully there is enough here to get you going.

Bill, I believe that PROJ.4 +x_0 and +y_0 values are always in meters, while the WKT (.prj) file has the false easting and northing in the units of the projected coordinate systems .. feet in this case. In any event, if you error is on the order of 100m then the problem is likely not the false northing being off by 350000 (meters or feet). That level of error is mostly likely related to the datum shifting not being applied or possibly a mixup between different kinds of feet. I am doubtful it is related to HPGN since my understanding is that the difference between NAD83 and HPGN is small (less than 5 meters say), though I am not too sure about that part.

Followed your workings and got what is a near perfect match for another scale. In doing so, I can see how is resolution is used, which was some explanation I hadn't found detailed elsewhere. Kept it at 72 dpi. Yes, preview is slow, but the results are nice. Gdalwarp changes projections if I am not mistaken. Do you mean gdal_translate to create the raster pyramids? Will have to give this a try later today as my rasters do vary, especially with inner-city areas. It loooks like I would supply the output size in pixels (x,y) to get the the desired scale. Definately info like this is helpful for us non-geo-versed. Need this kind of info in the --verbose docs!

The MINSCALE and MAXSCALE values are the denominators of scale ratios, like 1:10,000 scale. MINSCALE 10000 means "a minimum scale of 1:10,000", where one meter on the map equals 10,000 meters on the ground. The problem becomes, "what's one meter on the map"? The RESOLUTION statement answers that question. The default value is 72, meaning that 72 pixels in a MapServer output image are presumed to occupy one inch on the screen. This is actually unlikely to be an accurate value unless you're running a 20-year-old Macintosh, but it often doesn't matter - it's mostly used for internal calculations. So, if 72 pixels are presumed to cover one inch on the screen, and your image has a source resolution of 1.26956817 meters per pixel, then one inch on the screen will show 72 * 1.26956817 meters or 91.40890824 meters of image. Since 91.40890824 meters equals 3598.7687 inches, this means one inch on the screen shows 3598.7687 inches on the ground - a scale ratio of 1:3598.7687 If you displayed that image at the "scale" of 3598.7687 you should get a pixel-for-pixel replica of your source image. If you use a different RESOLUTION statement, you need to adjust accordingly. For calculating the IMGEXT values, you simply need to make the X extent and Y extent equal the number of (X or Y) pixels in the image times 1.26956817. Yes, there are better-quality ways of resampling images, but - as you saw in Preview - they're slow. MapServer doesn't use them, but you can use various tools (including gdalwarp, from the GDAL distribution) to resample images offline and create "pyramids" of varying resolutions. This will improve the display quality of your images while keeping the performance fast - at the expense of extra disk space and preprocessing work. - Ed Ed McNierney -------------- next part -------------- An HTML attachment was scrubbed...

Ok, well, I'm putting a stripped down version of my mapfile below. It has only two layers: one in each of the two projections. I tried replacing the "init=espg:27659" with the actual contents of my /usr/share/proj/espg in both the MAP level and the LAYER level, but it came back very messed up! So I thought that perhaps I'm going at this wrong: I created these mapfiles before I had any clue and haven't come back to them in a while. Would you guys mind checking my setup on these? I'd send the data, but it's 49MB, and I'm not sure how to extract a subset without messing it up and/or removing the problem. I'd appreciate it.

Bill, Your declarations look fine from what I know of your problem (I hadn't been following the discussion closely). But my guess is that the Roads layer is just not being converted back to NAD27 properly. Do you have the file /usr/local/share/proj/conus on your system? One way of testing would be to change the roads declaration to be NAD27 and see if that makes any difference.

Bill, Your declarations look fine from what I know of your problem (I hadn't been following the discussion closely). But my guess is that the Roads layer is just not being converted back to NAD27 properly. Do you have the file /usr/local/share/proj/conus on your system? One way of testing would be to change the roads declaration to be NAD27 and see if that makes any difference. If there is no noticable effect, then it likely means that the datum shift file is not being found and applied. PROJECTION "+proj=aea" "+lat_1=24" "+lat_2=31.5" "+lat_0=24" "+lon_0=-84" "+x_0=400000" "+y_0=0" "+datum=NAD27" "+units=m" "+no_defs" END > I'd send the data, but it's 49MB, and I'm not sure how to extract a subset > without messing it up and/or removing the problem. If you still can't get things working, bundle stuff up and let me know where to grab it and I'll take a crack at the problem.

I found in doing it that way, though, that the text would get a little blurred out. So I then decided to render my labels as a seperate image and just superimpose them over my antialiased map. The results have been quite good. First off, for image handling in php, you'll need to configure php --with-gd=/path/to/gd. It's important to make sure that the version of gd you configure it with is the same version as the one you compiled mapserver with. Also, just specifying --with-gd, and not including the path, will make php revert to using it's own bundled gd (probably not what you want). If you have problems with this step, search the archvies; there's been plenty of discussions about it. I wrote a function to call at the end of my mapscript like this: $image_url = antialias(2); where 2 is the scale factor. Increasing the scale makes the image look better, but also slows it down a bit. Here's the function. It should be relatively self-explanatory. I posted an older version of this function maybe a month back, but it's had some bug fixes since then. /////////////////////////////////////////////////////////////// // // function antialias() // // draws our map at a larger size, then samples it back down to provide // antialiasing. annotation layers and the scalebar are drawn seperately // and combined over the resulting image, so that they are not distroted. // // using this function, all labels must be drawn as seperate annotation layers. // // the .map file should be configured to output as png for transparency. // /////////////////////////////////////////////////////////////// function antialias($scale) { global $map, $root_directory; // get the dimensions of the image $image_width = $map->width; $image_height = $map->height; // scale the map up $map->set("width", $image_width * $scale); $map->set("height", $image_height * $scale); // turn off the scalebar if there is one $scalebar_present = false; $scalebar = $map->scalebar; if ($scalebar->status == MS_EMBED) { $scalebar->set("status", MS_OFF); $scalebar_present = true; } // loop through our layers, and if it's status is on, loop through the classes scaling the sizes $scaled_symbols = array(); for ($i=0; $i < $map->numlayers; $i++) { $layer = $map->getLayer($i); if ($layer->status == MS_ON AND $layer->type != MS_LAYER_ANNOTATION) { for ($j=0; $j < $layer->numclasses; $j++) { $class = $layer->getClass($j); for ($k=0; $k < $class->numstyles; $k++) { $style = $class->getStyle($k); // scale the size and offsets $style->set("size", $style->size * $scale); $style->set("offsetx", $style->offsetx * $scale); $style->set("offsety", $style->offsety * $scale); // for symbols with styles them, we need to scale those as well $symbol_id = $style->symbol; $symbol = $map->getsymbolobjectbyid($symbol_id); $already_scaled = false; reset($scaled_symbols); foreach ($scaled_symbols as $scaled) { if ($scaled == $symbol->name) { $already_scaled = true; } } if (!$already_scaled) { array_push($scaled_symbols, $symbol->name); $points = $scaled_points = $symbol->getstylearray(); if (count($points) > 1) { for ($l=0; $l < count($points); $l++) { $scaled_points[$l] = $points[$l] * $scale; } $symbol->setstyle($scaled_points); } } } } } } // loop through and turn off our annotation layers for now, keeping track of them $labels = array(); for ($i=0; $i < $map->numlayers; $i++) { $layer = $map->getLayer($i); if ($layer->type == MS_LAYER_ANNOTATION AND $layer->status == MS_ON) { array_push($labels, $layer); $layer->set("status", MS_OFF); } } // draw our image $image = $map->draw(); $image_url = $image->saveWebImage('MS_PNG', 1, 1, 0); // create our image objects $old = imagecreatefrompng($root_directory . $image_url); $new = imagecreatetruecolor($image_width, $image_height); // the background color gets dropped from our transparent pngs, so start by filling our new image with it $back_color = $map->imagecolor; $back_color = imagecolorallocate($new, $back_color->red, $back_color->green, $back_color->blue); imagefill($new, 0, 0, $back_color); // resample the image back down to the original size (antialiasing it) imagecopyresampled($new, $old, 0, 0, 0, 0, $image_width, $image_height, $image_width * $scale, $image_height * $scale); // scale the map down $map->set("width", $image_width); $map->set("height", $image_height); // flip off all layers on the map for ($i=0; $i < $map->numlayers; $i++) { $layer = $map->getLayer($i); $layer->set("status", MS_OFF); } // flip on those annotation layers we turned off earlier for ($i=0; $i < count($labels); $i++) { $labels[$i]->set("status", MS_ON); } // turn the scalebar back on if ($scalebar_present) { $scalebar->set("status", MS_EMBED); } // draw our image again, this time with just the annotations $label_image = $map->draw(); $label_url = $label_image->saveWebImage('MS_PNG', 1, 1, 0); // merge the text from our new image over the old one $old = imagecreatefrompng($root_directory . $label_url); imagecopyresampled($new, $old, 0, 0, 0, 0, $image_width, $image_height, $image_width, $image_height); // change our filename extention from .png to .jpg $image_url = substr($image_url, 0, -3) .

If I set the projection in a cgi-script, everything is displayed correctly. To draw the same map with the Perl API, I use this function: $map->setProjection("proj=eqc,lat_ts=63.495,lon_0=46.165"); Then I calculate extent with the command "proj": proj +proj=eqc +lat_ts=63.495 +lon_0=46.165 < 40.5 60.41 > 51.83 66.58 And get: -281432.71 6724810.44 281432.71 7411651.70 Set extent in my program: $map->setExtent('-281432.71','6724810.44','281432.71','7411651.70'); In the result, I get the map shifted exactly to the north, with the extent of latitude about from 60,6 to 66,8 instead of 60,41 and 66,58. The extent of longitude is correct. What is the cause of this error? Can I set the projection in Perl, without setting the extent? Hope for Your help.

BUT I have tried and tried, and have never been able to print any ArcGIS map containing a WMS layer successfully. All non-WMS layers will print fine, but the WMS layers are missing, as if when the map regenerates for printing, no time is given to allow the WMS source to re-send it's part of the map. Also, any type of exporting the map ... to JPG, to PDF etc. will have the same problem. So unless someone knows what I'm doing wrong, ArcGIS will display WMS, but not print or export WMS, making it fairly useless.

The 2 parts I can see that might be trouble are Postgres and PHP. Postgres adds a postgres user to the NetInfo database (if needed), and adds a line to /etc/hostconfig (if needed). PHP modifies /etc/httpd/httpd.conf - once with the apxs tool to enable PHP the standard way, then again to get it to use PHP in the custom location. Doesn't look like there should be install problems. I can't find any info on which version of Apache is default/included in Tiger. If it's 2, MapServer probably won't work. At least PHP-MapScript won't, CGI mapserv may work. But the PHP install may have issues.

In fact, I am displaying one of two different GRASS rasters, both possessing null(no data) areas over oceans. One of the rasters works just fine, allowing one to view the bathymetry through the transparent areas, while the other is quite opaque. As far as I can tell, both rasters have data ranges of 0-255, and have null(nodata) values over ocean areas when I use d.what.rast. You can view the effect at http://falstaff.unm.edu/cgi-bin/reason/raster_processing_client.py Under the Background Raster Layers dropdown, select the shaded relief to compare to the default background when the page opens. Any ideas on why one works and the other doesn't would be greatly appreciated. Bill. From dcmikkelsen at SHAW.CA Tue Apr 26 10:58:34 2005 From: dcmikkelsen at SHAW.CA (Dean C.

Message-ID: Dear MapServer users community, I have a problem with the getShape function in php/MapScript when using a PostGIS database. One of my table contains a column/field of a special type which can't be converted to text. Unfortunately, the getShape function wants to convert all the fields to text and gives an error status. Did someone fixed this problem already in a custom way? Perry Casson had the same problem one year ago with a field of type "bit" (see the attached mails). I do not want to change my data type, as suggested by David. Is there a way to force getShape to select only a subset of the PostGIS fields for example? Or simply to ignore fields which are not castable to text? This would be a simple solution. In the long run, as PostGIS becomes more and more popular, is it planned to add some PostGIS-specific functions to the php/mapscript API? And is it already possible to use msPOSTGISLayerGetShape() directly instead of getShape(), for example? Thank you for your support, and thanks to the refractions.net team for their great work on php/mapscript!

If you pasted your MapServer configuration command, the mapscriptvars file, and the output from the mapserver make and Python build, I will be glad to review them and see if anything is obviously wrong. cheers, Sean -- Sean Gillies sgillies at frii dot com http://users.frii.com/sgillies From schuyler at NOCAT.NET Tue Apr 26 13:38:19 2005 From: schuyler at NOCAT.NET (Schuyler Erle) Date: Tue, 26 Apr 2005 13:38:19 -0700 Subject: tiling shape files, or shptree In-Reply-To: <200504261324.31111.dylan@iici.no-ip.org> Message-ID: * On 26-Apr-2005 at 1:24PM PDT, Dylan Beaudette said: > > for example: i have a statewide local roads shapefile (TIGER 2000). this > layer is not enabled until the user is zoomed in quite a bit. will i get > faster map rendering times if i : > > 1. tile the statewide coverage into small rectangles > > 2. use shptree to create a spatial index > > 3. do both You want Steve Woodbridge's shp2tile.

When i use ogrinfo, to determine the Extent of a shapefile(in this case the zipcode boundries for the state of Missouri), how do I know what units the values are in? Is the minx value below -95.774704 meters, feet, or something else? Or maybe the minx value is expressed in degrees, minutes, seconds. How can I tell? Below is what output from ogrinfo on the aforementioned shapefile.

In-Reply-To: Message-ID: Thanks a lot Abe, Adding postgres views in the map file seems to be the best way, since the php/mapscript functions are quite generic. I'll work on it. Besides, I'll also try my own Poatgres queries with DB.php using the oid retrieved by MapServer's querybypoint(). Could you please comment on the C vs. php performances for MapServer? At which number of layers/entries do I have to say goodbye to the php/mapscripts? At the moment, I can generate a map within 1,5 sec with 2000 polygons in one table and <100 points/polygons in 6 other tables. Strangely, if I add the labels of the large table, my performances are ridiculous, e.g. up to 3 sec for a map. Is the label positioning known to be slow?

Is there a significant performance difference between using shptree/tileindex and shp2tile/tile2index? Since shptree already uses quadtrees, I imagine the main performance difference is to minimize seeks on the data?

Here is an example URL: http://devgeo.cciw.ca/cgi-bin/mapserv/mapserv?map=/usr/local/wwwsites/ap ache/devgeo.cciw.ca/apps/mapserv/apps/basicviewer/config.map&context=htt p://devgeo.cciw.ca/ms_tmp/wqm_loc.cml 1./ If you check out the WMC doc (http://devgeo.cciw.ca/) you'll see that all layers have a Layer/@hidden value of 0, which means they should be visible. However it appears that one must explicitly call these layers via LAYERS in the CGI URL, i.e.: http://devgeo.cciw.ca/cgi-bin/mapserv/mapserv?map=/usr/local/wwwsites/ap ache/devgeo.cciw.ca/apps/mapserv/apps/basicviewer/config.map&context=htt p://devgeo.cciw.ca/ms_tmp/wqm_loc.cml&layers=wa_7.5m& I can see why this is the case, however I would imagine it would be more intuitive if, when no LAYERS parameters are set, to return the WMC as it was intended to be viewed? 2./ How does the WMC get marshalled in CGI mode? i.e. I'm trying to use the HTML legend approach to build a legend. I'd like to pick up the LegendURL, MetadataURL and Title from the Layer element to populate the legend. At any rate, kudos to the developers for adding this functionality, which allows for a *very* light standards-based client.

I don't know if you are using mapscript or mapserver, but I know another way you could do it would be to use mapscript to read the values from the columns you need for your label and create a new variable that formats the data how you want it to appear, and then set the label to use that variable for its text. This is clipped out of an email where Steve Woodbridge answered a similar question of mine: set the CLASS -> TEXT -> value to the string you want output. so something like: $oClass->set("text", $mytext); should do it.

It does not combine shapefiles into one shapefile. Each input shapefile has its bounding box retrieved, and a rectangular polygon is created in the new tile index shapefile. If you started with N shapefiles you now have N+1 shapefiles - all the originals and the index file. Let's say each original shapefile contained data for a particular country. If you wanted to create a map showing every country, you would have to create a few hundred separate layers then group them together. By creating a tile index layer, you can take a large number (or small number) of separate shapefiles and treat them AS IF they were one single large shapefile - but they're not. This is the primary benefit of a tile index. IF your data in the separate files are relatively constrained to rectangular regions, then the tile index also will offer you a performance improvement. It's like a new top-level index for your data. If you're looking at a large-scale map of Europe, the tile index file will immediately discard any of those input country files whose rectangular bounding boxes do not overlap the output map area. Most of the input country files will never be opened - only the few files that might possibly contribute to the output map are opened and read. For large data sets this improves performance. Steve's shp2tile utility helps to create such an appropriate set of input files, by taking a single large input shapefile and chopping it up into rectangular pieces. shptree creates a spatial quadtree index for a shapefile that makes it quicker to locate objects inside that file. This is virtually always a good idea, and easy to do. You may have to tune your data set sizes to get the right balance. The goal is to use the tile index file to quickly discard data that cannot possibly be needed for an output map request. If you end up rendering all the data, or opening all the files, it will do you no good at all. - Ed Ed McNierney TopoZone.com ________________________________ From: UMN MapServer Users List [mailto:MAPSERVER-USERS at LISTS.UMN.EDU] On Behalf Of Jeff Portwine Sent: Wednesday, April 27, 2005 8:30 AM To: MAPSERVER-USERS at LISTS.UMN.EDU Subject: [UMN_MAPSERVER-USERS] different tiling methods Hi Everybody, I have a general question for my own education, it doesn't directly pertain to anything I'm working on right now.

My guess is that if you are already using shptree and tileindex, shp2tile will give you some performance advantage but not significantly so. The main thing that shp2tile does is to balance out your data so you take advantage of the underlying cluster effect. shp2tile WOULD have a huge performance advantage if you are not using shptree on the underlying shapefiles though. I could be wrong but that appears to me the difference.

We use geographic projections for all of our layers, and things work just fine. While I can see that the geographic projection can be slightly confusing in that the points are not always equidistant, they still work fine for most applications (especially when you're only dealing with limited coverage areas).

So far, I have not run into performance problems with shptree alone but I might try shp2tile and see if there's a noticeable difference. My guess would be similar to the difference between a pure b-tree and a balanced b-tree or even a b+-tree. Shp2tile keeps geographically related items together so you take advantage of the cluster effect and minimize the average seek times. A balanced tree will give you much more deterministic response where an unbalanced tree could potentially have very bad performance in degenerate cases.

I agree. Time to find my Snyder book again. As I said we're overlaying some unprojected data ontop of MapServer (unfortunately I can't do it from within MapServer) so we'd have to project in two separate applications. This still doesn't answer my question on exactly what is the correspondence between Unit dd and Scale Units, as far as Mapserver is concerned, but I guess I can Use The Source on this one. A quick check with Mapquest shows that at least in parts of New Jersey, the distance on the scalebar is roughly correct.

Tim / Schuyler, Yes, I've thought about that sometimes too. It might be helpful to have a tool that would would copy a shapefile in .qix traversal order. That is to reorder the features by locality as determined by the quadtree index. That might given the convenient managability of one big shapefile with the locality benefits of tiling.

These are distributed in gdal/data (in source dists.) and you can point to them with the GDAL_DATA environment variable. > It works. Fortunately, for this application, I don't need to project the > data. Right. Also, in a mapserver context the OGR coordinate system is ignored, and you need to specify things in the .map file in a projection block. So OGR's concept of the coordinate system is normally only important if you are using external ogr utilities or other OGR applications.

When I use php mapscript querybypoint to get the elevation at the point, it takes a long time (8 seconds). ->getResult(0) returns a tileindex and shpindex of the result. That leads me to believe that the querybypoint queries all tiles and not just the ones in the current extent. I am also lead to believe that querybypoint searches all tiles since there is no improvement of search speeds when I am zoomed in. I would think the farther I am zoomed in, the number of tiles used should be smaller, therefore the amount of time required for a search should be less if querybypoint only seached the tiles related to the current extent. When the map draws, it may draw using only 4 tiles at a "zoomed in" extent. I was hoping that querybypoint would only query those same 4 tiles for the result. Could someone tell me if querybypoint searches in the tiles associated with the current extent or does it look at all tiles listed in the tile index? If querybypoint searches all tiles, is there anyway to query a small extent of a map, thereby reducing query times. If it only searches the tiles associated with the current extent, then I have tiling problems.

This is the usual "latest from CVS" release. Noteworthy changes include: On Windows: o Use of the ECW 3.1 SDK, with the name of the DLLs renamed to include _fw so they don't interfere with any older versions already installed in windows\system32 on windows as had been reported by several people. o Included all the GTK related include files and stub libraries. In theory this should make it fairly easy to use FWTools to build the OpenEV core against instead of folks having to build all the dependencies themselves. On Linux: o I was having problems with a message about libgcc_s.so not being properly installed and this interfering with pthread_cancel in the ECW library. I think I have worked around this by moving the libgcc_s.so into $FWTOOLS_HOME/lib/fallback and putting it after /lib in the LD_LIBRARY_PATH. Apparently it is important to use the installed libgcc_s.so if it is available.

That should help clustering the blocks together. I am not very familiar with the .qix format but I don't think it actually tries to balance the quadtree at all right now. A mostly balanced algorithm with a re-sorted shapefile might be a good approach. Also, I wonder what would happen if you run a big shapefile through shp2tile, merge the shape files back sequentially into a big file, then run shapetree on it. Seems like you'd get most of the effects of above. http://www.cs.umd.edu/~brabec/quadtree/ has lots of spatial index algorithms. One of these days I'll read through all of them.

Avoids the need for unnecessary cleans on win32. Also fixed the rule for MS_VERSION for mapscriptvars. - Bug 1262 : the SERVICE parameter is now required for wms and wfs GetCapbilities request. It is not required for other WMS requests. It is required for all WFS requests. - Bug 1302 : the wfs/ows_service parameter is not used any more. The service is always set to WFS for WFS layers. - Bug 791: initialize some fields in msDBFCreate() - avoids crashes in some circumstances. - Bug 1329 : Apply sld named layer on all layers of the same group - Bug 1328 : support style's width parameter for line and polygon layers. - Bug 1244: Replacing --enable-shape-z-m by --enable-point-z-m and replacing USE_SHAPE_Z_M by USE_POINT_Z_M. The new name makes more sense. - Bug 564: Fixed old problem with labels occasionally drawn upside down - Bug 1325: php mapscript function $class->settext needs only 1 argument. - Bug 1319: Fixed mutex creation (was creator-owned) in mapthread.c. win32 issue only. - Bug 1103: Set the default tolerance value based on the layer type. The default is now 3 for point and line layers and 0 for all the others. - Bug 1244: Removing Z and M parameter from pointObj by default. A new compilation option is available to active those option --enable-point-z-m. This gives an overall performance gain around 7 to 10%. - Bug 1225: MapServer now requires GD 2.0.16 or more recent - MapScript: shapeObj allocates memory for 4 value strings, shapeObj.setValue() lets users set values of a shapeObj. - MapScript: imageObj.getBytes() replaces imageObj.write() (bugs 1176, 1064). - Bug 1308: Correction of SQL expression generated on wfs filters for postgis/oracle layers. - Bug 1304: Avoid extra white space in gml:coordinates for gml:Box. - mapogr.c: Insure that tile index reading is restarted in msOGRLayerInitItemInfo() or else fastcgi repeat requests for a layer may fail on subsequent renders. - mapogr.c: Set a real OGRPolygon spatial filter, not just an OGRLinearRing. Otherwise GEOS enabled OGR builds will do expensive, and incorrect Intersects() tests. - mapogr.cpp / mapprimitive.c: Optimize msAddLine() and add msAddLineDirectly() - mapprimitive.c: Optimizations in msTransformShapeToPixel() (avoid division) - map.h: Made MS_NINT inline assembly for win32, linux/i86. - mapprimitive.c: optimized msClipPolygonRect and msClipPolylineRect for case where the shape is completely inside the clip rect. - Add support for SVG output. See Bug 1281 for details. - Bug 1231: use mimetype "image/png; mode=24bits" for 24bit png format. This makes it seperately selectable by WMS. - Bug 1206: Applied locking patch for expression parser for rasters. - Bug 1273: Fixed case in msProjectPoint() were in or out are NULL and a failure occurs to return NULL. Fixed problem of WMS capabilities with 'inf' in it. - SLD generation bug 1150 : replacing tag to - Fixed bug 1118 in msOWSGetLayerExtent() (mapows.c). - Fixed ogcfilter bug #1252 - Turned all C++ (//) comments into C comments (bug 1238) - mapproject.h/configure.in: Don't check for USE_PROJ_API_H anymore. Assume we have a modern PROJ.4. - Bug 839: Fix memory leak of font name in label cache (in mapfile.c). - Added msForceTmpFileBase() and mapserv -tmpbase switch to allow overriding temporary file naming conventions. Mainly intended to make writing testscripts using mapserv easier. FrankW. - maporaclespatil.c: Bug fix for: #1109, #1110, #1111, #1112, #1136, #1210, #1211, #1212, #1213. Support for compound polygons, fixed internal sql to stay more accurate for geodetic data, added the support for getextent function. Added VERSION token for layer data string. - mapimagemap.c: Preliminary implementation of support for emitting MS_SYMBOL_VECTOR symbols in msDrawMarkerSymbolIM(). - Bug 1204: Added multi-threading support in mapthread.c. List of connections is managed within a mutex lock, and connections are only allowed to be used by one thread at a time. - Bug 1185 : php/mapscript : add constant MS_GD_ALPHA - Bug 1173: In HTML legend, added opt_flag support for layer groups. - Bug 1179: added --with-warnings configure switch, overhauled warning logic. - Bug 1168: Improve autoscaling through classification rounding issues. - Fixed bug writing RGB/RGBA images via GDAL output on bigendian systems. - Bug 1152 : Fix WMS style capabilities output for FastCGI enabled builds. - Bug 1135 : Added support for rotating labels with the map if they were rendered with some particular angle already. - Bug 1143 : Missing call to msInitShape. - Fixed PHP5 support for windows : Bug 1100. - Correct bug 1151 : generates twice a tag when generating an SLD. This was happening the style did not have a size set. - Oracle Spatial. Fixed problem with LayerClose function. Added token NONE for DATA statement. Thanks Valik with the hints about the LayerClose problem and Francois with the hints about NONE token. - numpoints and stylelength memebers of the symbol object needs to be in sync with the low level values after calles to setpoints ans setstyle (Bug 1137). - Use doubles instead of integers in function php3_ms_symbol_setPoints (Bug 1137). - Change the output of the expression when using a wild card for PropertyIsLike (Bug 1107). - Delete temporary sld file created on disk (Bug 1123) - Fixed msFreeFileCtx() to call free() instead of gdFree() as per bug 1125.

Bas, I am guessing that one of the 4 gdal12.dll's is in windows\system32, right? This location takes precidence over the PATH, but even higher precidence is the directory the program is running in.

I have used a spatial database (MySQL spatial) to store an image extents and metadata and retrieve this through a WFS before, but that was of little use (in terms of performance) and the data was still external to the database. Is there a way to store image chips (preferably in PostGIS or MySQL Spatial), and utilites this through MapServer WMS/WFS/WCS? Or any way of storing rasters in a database? This thought was triggered by the idea that if I have an archive of data which is several terrabytes in size it is going to need a database to index and manage it. Any thoughts by anyone who has done this kind of thing would be appreciated.

Luca, I believe this is mostly a defect of OpenEV's raster handling strategy and the way that GDAL represents ECW files to it. In particular, OpenEV creates a texture for each 256x256 chunk of the full res file. In overview on very large files this means that virtually every pixel on screen is a separate texture, and results in a seperate io request to the file - a most pathological case. I would add this isn't a problem for MapServer. In the raster code we take care to only make one request to the file per band, so at worst there are 3 reads from the ECW file for any given render, and they are done in such a way that full advantage is taken of the ECW overview capability.

Bas, I am guessing that one of the 4 gdal12.dll's is in windows\system32, right? This location takes precidence over the PATH, but even higher precidence is the directory the program is running in. I would suggest you move or rename the version in windows\system32.

As you can see on my website, there are *four* Python MapScript builds. At one time, you must have chosen either the "SDE" or "Full" build, which both have the SDE dependency. Use the "Normal" release at all times unless you have a need (and the dlls) for either SDE or Oracle. Regarding the extra gdal12.dll's in C:\python23\ and C:\python23\dlls... The Python uninstaller doesn't deal with dlls in the main sys.prefix directory very well on Windows (especially in an uninstall-reinstall cycle). I've had to manually delete these after an uninstall of Python MapScript (using the control panel). Python 2.4 (which I don't provide builds for) does better at this, and will uninstall dlls in the DLLs directory. Uninstall all of the mapscripts that you have using the control panel and then go into the python23 directory and delete the dlls by hand. This will clean up your Python directory. If you have other gdal12.dlls, you'll either have to move the PATH, clean them up, or do something with them as you see fit. Regarding the issue of not seeing which dll python can't find... run the python script using a command window (dos prompt), rather than IDLE or Activestate. The IDEs swallow the dialog for some reason. FWTools is more cleanly packaged than my mapscript binaries . It comes with its own Python and everything else you might need. I suggest you try it if you continue to have trouble with my binaries. Howard At 10:32 AM 4/28/2005, Bas Vanmeulebrouk wrote: >Frank, > >Thank you very much for your reaction.

Mapserver is compiled with wfs and wms client support and the wms client works fine. Ok, here is the layer definition in my map file. LAYER NAME countries TYPE POLYGON STATUS ON CONNECTIONTYPE WFS CONNECTION "http://webservices.ionicsoft.com/unData/wfs/UN?"

There are no errors returned with this layer is activated, but the output in the IMAGEPATH dir looks like this, and nothing is drawn. inapplicable I assume that this means Mapserver made a request to the wfs server, but no results were returned. First of all, how do I find out the exact URL request made to the WFS server? I suppose that I may be able to debug it this way. I can construct a url myself and the server returns GML correctly.

The GetCapabilities responds with (with respect to SLD): and the 'request=getStyles' request reports back fine as well (indicating the styles I set in the CLASS block). Using the CLASS block without the SLD works as expected, too. (BTW, under normal circumstances will the SLD override the CLASS specified in the map file?) The '&style=' parameter makes no difference whether it is present or not. Does Mapserver have a debug mode where I could trace what is going on internally?

A few questions: -is your WMS GetCapabilities working? -does the LAYER work without an SLD, ie when you specify a CLASS? -does it work if you leave out the style parameter in the request? -your WMS request is not a full WMS request, it should contain a BBOX, WIDTH, HEIGHT and SRS (among others).

My mapping application allows users to dynamically add layers using a wizard (similar to MS-ACCESS Report Wizard, where the user can select fields from different tables). The application generates SQL from this selection, more precise, the truncated SQL part which forms the DATA element of a layer. To be on the safe side with table and column names (I use PostGIS) I put all names in quotes. However when I then dynamically save the mapobj to a mapfile, mapscript places quotes around the DATA statement, which when trying to load that file again, will cause problems as the parse thinks the the first quote is the end of the DATA element, which it obviously isn't. I noticed that with EXPRESSION's when putting the expression inside parantheses () it will not enclose the expression with quotes, however trying to do so with DATA doesn't work. Since I keep the meta-information of my layer wizard, I can just simply set DATA to an empty string before saving the map, and use that meta-information (stored in the file as METADATA) I can re-generate my DATA string when loading the file. However I don't like this solution and was wondering if there is a better solution for cases when the DATA string itself contains quotes (as well as single quotes).

I asked on the list about such a spatial sorting program in a post entitled "Query: sortshp, spatially clustering shapefiles on disk" on or about 23rd July 2004. I discussed a couple of references in that message which deal with this idea well. I didn't get a positive response, so I did it myself. My program's based on programs in the mapserver distribution (particularly, maptree.c which is Frank's). If my memory serves me correctly, it's pretty basic - reads and writes each shape one at a time, then reads and writes the DBF file records one at a time. Nevertheless, on our Sun system (a 480R with 16 GB), it sorted the entire cadastre for my state (1.3 GB, 4 million polygons) in about 8 minutes. I've marginally altered Frank's spatial indexing so that it visits nodes following a Hilbert-Peano scan, so that sequential nodes are spatially adjacent. I shall re-visit my code and polish it up. It would fit in with "shptree" and "maptree" from which it's derived. What's the best way of contributing this to the codebase? Sorry about the delayed reply, but I only read the digest.

That should help clustering the blocks together. I am not very familiar with the .qix format but I don't think it actually tries to balance the quadtree at all right now. A mostly balanced algorithm with a re-sorted shapefile might be a good approach. Also, I wonder what would happen if you run a big shapefile through shp2tile, merge the shape files back sequentially into a big file, then run shapetree on it. Seems like you'd get most of the effects of above. http://www.cs.umd.edu/~brabec/quadtree/ has lots of spatial index algorithms. One of these days I'll read through all of them.

I just read your July 2004 post and it seems to me if you've modified the program to be one pass, there's no reason why it couldn't replace the existing sortshp or maptree (perhaps with a added flag for compatibility reasons). Have you done any performance measurements of your new code? Thanks for the interesting spatial indexing paper references too. I'll let Frank or others answer your question regarding contributing the code. You can probably post it to the developer's list and let somebody take it from there.

When you submit the code, please be fairly specific about this "Hilbert-Peano Scan" as I would potentially like to apply it in the seperate version of the spatial index code in in shapelib and OGR. > I shall re-visit my code and polish it up.

I thought I had downloaded the Python Mapscript build without SDE and Oracle support, but of course I may be mistaken. I have solved the gdal12.dll problem. And when I run a Python script in which I use "import mapscript", everything runs fine. I can create a new mapObj and save it to an image. However, if I call this script via the Apache webserver, I get the internal server error. I have downloaded the FWTools package and I will try it next week. Kind regards, Bas. -----Original Message----- From: Howard Butler [mailto:hobu at iastate.edu] Sent: Thursday, April 28, 2005 6:16 PM To: Bas Vanmeulebrouk; MAPSERVER-USERS at LISTS.UMN.EDU Subject: Re: Installing Python Mapscript on Windows XP Bas, Regarding the SDE depencency in my MapScript builds.... you need to be very careful to get the exact Python MapScript you need. As you can see on my website, there are *four* Python MapScript builds. At one time, you must have chosen either the "SDE" or "Full" build, which both have the SDE dependency. Use the "Normal" release at all times unless you have a need (and the dlls) for either SDE or Oracle. Regarding the extra gdal12.dll's in C:\python23\ and C:\python23\dlls... The Python uninstaller doesn't deal with dlls in the main sys.prefix directory very well on Windows (especially in an uninstall-reinstall cycle). I've had to manually delete these after an uninstall of Python MapScript (using the control panel). Python 2.4 (which I don't provide builds for) does better at this, and will uninstall dlls in the DLLs directory. Uninstall all of the mapscripts that you have using the control panel and then go into the python23 directory and delete the dlls by hand. This will clean up your Python directory. If you have other gdal12.dlls, you'll either have to move the PATH, clean them up, or do something with them as you see fit. Regarding the issue of not seeing which dll python can't find... run the python script using a command window (dos prompt), rather than IDLE or Activestate. The IDEs swallow the dialog for some reason. FWTools is more cleanly packaged than my mapscript binaries . It comes with its own Python and everything else you might need. I suggest you try it if you continue to have trouble with my binaries. Howard At 10:32 AM 4/28/2005, Bas Vanmeulebrouk wrote: >Frank, > >Thank you very much for your reaction.

Daniel, I believe if you submit a bug report on this topic we could try and alter the map writer to use single quotes if the DATA string has double quotes, but no single quotes. I'm not sure if there is a more general escaping mechanism for the case where string constants need both single and double quotes but if there is then the map saving logic should use it.

Although I have not benchmarked it carefully, I believe that the reason many users see a benefit from a TILEINDEXed set of smaller shapefiles when compared to a single large shapefile is the physical grouping of geographically nearby features on disk. A sorting scheme like yours might both eliminate the need to chop up larger shapefiles (if that's not otherwise desirable to the user) and/or improve smaller shapefile performance where the data are not geographically sorted to begin with.

Solaris 9 (dunno about 10) is a hybrid of Sun's proprietary linker and libraries with GNU's compiler and utilities, and the combination makes software builds a bit iffy sometimes. With Solaris I've often had problems with compiling programs that expect to be in the "100% GNU environment" of Linux. So, if it does work for you, I recommend saving a text file of your build procedure, because you'll probably end up using special config flags and environment variables, and having them in hand for next time saves a lot of time. (Our server is FreeBSD, and we had similar issues. The software does port easily *once* you know the ins and outs for your OS.) __________________________________________________ Do You Yahoo!?
