You're providing an excellent resource for users that wish to get into web mapping and don't have the budgets to go out and buy MapXtreme or ArcIMS. Through Directions Magazine I've had the opportunity to use many of the commercial solutions available and some of the demos built with Mapserver are far more impressive. I have also built several map server systems on the Windows platform using various GIS objects and if I can get Mapserver to do what I want it to, I may abandon my own favorite server. Now for my problems.... I am running FreeBSD 4.2-RELEASE. I can reliably compile and use Mapserver 3.3 and 3.4 or the nightly build as a CGI binary with no problems but I have had no luck building any version with PHP 4.0.5 or 4.0.6 as a dynamic module. Configuration goes fine using: ./configure --with-gd=/usr/local --with-jpeg=/usr/local --without-ttf --with-php=../php-4.0.6 --with-apxs=/usr/local/www/bin/apxs --enable-runpath >From what I've read, configuration on FreeBSD is a bit goofy... I end up with the following in my mapscript/php3/Makefile: CC = cc undef -I. -I.. -DPIC -fpic LD = cc -Wl -Wl CFLAGS = -O2 -Wall -DCOMPILE_DL=1 -DPHP4 RUNPATHS= -R/usr/local/lib -R/usr/local/src/mapserver >From here I remove undef from CC options and try for a build. It attempts to link with: cc -Wl -Wl -o php_mapscript.so php_mapscript_util.o php_mapscript.o mapscript_i.o -R/usr/local/lib -R/usr/local/src/mapserver -L/usr/local/src/mapserver -lmap -L/usr/local/lib -ljpeg -L/usr/local/lib -lgd -lpng -lz -lm And I end up with a bunch of undefined references in php_mapscript_util.o (zend_error, zend_list_find and so on and so on). The last line is: /usr/local/src/mapserver/libmap.a(maplabel.o)(.text+0x1096): more undefined references to `imageStringTTF' follow *** Error code 1 And I get no farther. Does anyone have Mapscript/PHP running under FreeBSD 4.0 or higher with a recent release of PHP 4? Any suggestions to push me in the right direction? Thanks in advance.

This still won't work unless you also switch the slashes on the GDAL_DIR somewhere else on that Makefile. The problem with this is that the DOS (or Windows) copy command uses the backslash (\) in paths. Nmake itself don't have that problem but system commands do. For uniformity's sake, you might want to switch all the path slashes to backslash. Example Makefile.vc: ...(stuff omitted) GDAL_DIR= ..\..\gdal OGR=-DUSE_OGR OGR_LIB = $(GDAL_DIR)/ogr/ogrsf_frmts/ogrsf_frmts.lib $(GDAL_DIR)/ogr/ogrsf_frmts/ogrsf_frmts_sup.lib $(GDAL_DIR)/ogr/ogr.lib $(GDAL_DIR)/ogr/../port/cpl.lib OGR_INC = -I$(GDAL_DIR)/ogr/ogrsf_frmts -I$(GDAL_DIR)/ogr -I$(GDAL_DIR)/port ...(more stuff omitted) $(MS_LIB): $(MS_OBJS) copy $(GDAL_DIR)\gdal.pdb . lib /out:$(MS_LIB) $(MS_OBJS) ...(the rest of the stuff omitted) Good luck! -Perry On Mon, 2 Jul 2001, David Armstrong wrote: > i am getting the following error when running the makefile.vc under windows > 2k with visual studio nmake command > > copy ./gdal-1.1.4/gdal.pdb . > The syntax of the command is incorrect. > > > the following is the offending lines in the makefile can anyone put some > light on this > > $(MS_LIB): $(MS_OBJS) > > copy $(GDAL_DIR)/gdal.pdb . > > lib /out:$(MS_LIB) $(MS_OBJS) > > > i can overcome this manually by copying the file across and commenting out > the copy command , but i would like to correct this > > Regards to All > Dave > From morissette at dmsolutions.ca Mon Jul 2 12:53:25 2001 From: morissette at dmsolutions.ca (Daniel Morissette) Date: Mon, 02 Jul 2001 15:53:25 -0400 Subject: [mapserver-users] Need TAB files for testing References: <3B3A0B7C.DC688E8C@dmsolutions.ca> <3B3CFEF8.76E45A49@dmsolutions.ca> <00ab01c101be$a718d100$0a729acb@tei.or.th> Message-ID: <3B40D135.9CDCFDD3@dmsolutions.ca> Paul Hastings wrote: > > > The Newfoundland demo is at: > > http://www2.dmsolutions.ca:8099/nfld_demo/demo_init.html > > all i see is a black box with "Powered by MapServer", a scalebar, > & a legend (besides the normal text). no map is displayed though > it seems that the map image is there but maybe the scalebar > image overlaps it???. below is the html source from my end: > Ooopps... there was a problem with the WIDTH and HEIGHT parameters of the IMG tag in the HTML template.

The alternative is a cumbersome number of checkboxes and associated titles on the map. The usual practice is to build a number of discrete .map files which call their respective template files, which in turn provide the options. These map and template files usually sit on the mapserver server, not accessible to most users. Is it possible to do this from a remote URL? It certainly is easy enough to initially configure the mapserver - zoom into the area of interest and turn some applicable layers on, then shift control to the mapserver proper. But when the user goes back to the external URL any changes are undone. The proper way is to implement a proper open GIS, but I presume that's not yet an easy task. Any clues on options would be appreciated and, in the meantime, I'll continue experimenting.

It provides functionality very similar to what the MapServer Tcl Workbench allows you to do, except that it's a Java Servlet that runs on the MapServer server, and you access it via a web browser... so you can use it to administer remote servers just like if you were sitting besides them.

Then the tile index shapefile is referred to as the TILEINDEX parameter in your mapserver layer defn. When Mapserver draws that layer, it scans the tileindex file, and displays all the counties whose extents fall in the current map extents. I think an example would help... is there any demo using TILEINDEX anywhere Steve? Another option could be to use a MapInfo "Seamless TAB dataset"... it's supported directly by OGR and does a job equivalent to what MapServer's tiled shapefiles do. Also, about SDE being the only DB format available, I think that's not true any more... I think Frank Warmerdam added support for the new PostGIS (http://postgis.refractions.net/) database in OGR... so you could use the OGR2OGR tool to load your layers in a PostGIS database, and then use MapServer + OGR to serve maps from that database. I'm not sure what the status of all those components is though... perhaps Frank can comment on this. -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

Haven't tried a draw though. MapServer gets extents for layers by actually accessing the layers. For non-tiled data that involves opening the file and reading header info. For tiled data it's a bit smarter. It used the layer tileindex to determine which tiles to process and then proceeds through them. Sounds to me that's what you're refering to in the last couple of sentences. Users have used county-based GDT and Tiger for the whole country using MapServer. Of course you wouldn't want to display city streets for the whole country at once so tying layers to appropriate scales is important... BTW I will be adding a LAYER EXTENT property to that you can bypass the file header check.

I think Frank Warmerdam added support for the new PostGIS (http://postgis.refractions.net/) database in OGR... so you could use the OGR2OGR tool to load your layers in a PostGIS database, and then use MapServer + OGR to serve maps from that database.

Folks, It should now be possible to use PostGIS as a spatial database for MapServer pre3.5 via the OGR linkage, as long as you build and install OGR from the current CVS source. I tried setting up a mapserver demonstration using OGR and PostGIS, but got bogged down in some sort of database permissions problem when running as nobody and never got back to fix it. Note that this OGR support for PostGIS and PostGIS itself are quite new, so this approach is really only suitable for someone willing to risk some pain getting things going. However, the PostGIS spatial quieries can be rocket fast, and I think this is a promising approach for MapServer users wanting to use a DBMS but without SDE. I should warn though that any queries that actually pull alot of data out of PostGIS are going to be kind of slow due to the inefficiencies of all the data handling within PostGIS, and in OGR. Converting the internal representation of stuff to text (OGC WKT), pulling it back one record at a time into OGR. Converting to OGRFeatures. Converting those to shapes structures within MapServer. If performance becomes an overriding concern we might eventually want to build a direct MapServer to PostGIS linkage, as well as look at optimized approaches to getting the data out.

It seems to me that it has no idea where the extents are unless it does in fact load each layer so I'd like to load layers dynamically based on the requested extent of the view.

When using the new gdImageCreateTrueColor function, the pixels array becomes invalid and you must use the tpixels array. Instead of gdImageColorAllocate, you can use either gdImageTrueColor or gdImageColorResolve, the latter of which is compatible with both palette and true color images. Another thing to note is that gdImageColorAllocate doesn't set the background color for a true color image the first time it's called. My workaround was to call gdImageFilledRectangle and fill the background with white manually in msLoadPalette(). My results so far have been discouraging. Mapserver creates all the images, but black seems to be the only color that works. The legend text prints out, and the scalebar works as well. Note that they both use only the color black. If anyone wants a diff so they can work on it, I'll whip one up. I'm going to continue fiddling with it. ;) BTW: If anyone has trouble linking GD 2.0.1 into mapserver on freebsd, email me for a fix.

With versions of GD that support multiple file formats there is a map level parameter IMAGETYPE that allows you to choose. 3.5 supports GD 1.3 to 1.8 including patched versions so with a fully decked out version you can output GIF/PNG/JPEG/WBMP. MapServer will support GD 2.x once it has stabilized a bit and 3.5 has been released. GD 1.2 is only used in the compile process as a last resort. There is a --with-gd configure option to change what version you're using.

Native PostGIS support in mapserver is in the testing phase. We have been testing it on (1) solaris PostGIS server with an i386 linux mapserver client and (2) PostGIS and mapserver on the same i386 server. The PostGIS performance has been about 1/2 to 1/3 the speed as using shapefiles on a RAID device. Our test machine is a fast athlon running linux with a RAID filesystem. Our test dataset is about 200,000 roads. Both mapserver and PostGIS/postgres are running on the same machine. To make a map of a very small area (about 25 roads), it takes about 0.25 seconds using PostGIS and about 0.1 seconds using shapefiles. To make a map of all the 200,000 roads, its takes about 4.5 seconds using PostGIS and about 1.3 seconds using shapefiles. The process works as: -> -> -> There should be lots of places to do some optimizations. I just came back from a holiday, and paul is still away on holiday, so it'll be a while before I can get it all wrapped up nicely, tested, and get a proper configure script. Once thats done, we'll make a release. If anyone out there can help with the "./configure" script, we'd really appreciate it. If you want to see the current version, I'd be happy to tar it up and send it out to you. dave ps. thanks to Daniel Morissette and the other authors (Frank Warmerdam???) of mapogr.cpp for writing easy-to-understand code.

This is only true however if the SDE and Oracle instances are tuned AND your requests is limited in extent (i.e., don't try to draw all the contours for the state of Virginia when zoomed all the way out). If your view window is of reasonable size SDE will smoke -- assuming things are tuned correctly. It makes sense if you think about the process. If you ask a database for the ALL the records you need to go through the DB, SDE blah blah and it would probably be easier to get a single file. However, if you only want a few records (i.e., spatial features) a DB can consult an index, search it very fast and return your request. I think the same idea can be used for small data sets. Do I really need to go through the DB/SDE etc. for the county boundaries? Probably not.... I'm curious how you have SDE on a Linux Box? Did you get a pre-release or something? The tuning comes in many levels. These range from hardware (e.g., RAID configurations, network hardware) to Oracle (about a million setting here) and SDE (i.e., grid tiling mostly). Each SDE layer needs to be tuned separately. It's a bit of a pain but it needs to be done. Don't use the GUI Arc Loaders---use the command line SDE tools. On ESRI's website you can get the SDELoader/SDEMonitor utils to help with tuning a bit. As for the error I haven't seen that one. I'm still having a few issues with queries against SDE from ms but....none exactly like that. -----Original Message----- From: Andrea Goethals [mailto:andreag at geoplan.ufl.edu] Sent: Tuesday, July 10, 2001 1:23 PM To: mapserver-users at lists.gis.umn.edu Subject: [mapserver-users] SDE performance and error I thought the posting the other day about the performance of PostGIS vs shapefiles was interesting. >>The PostGIS performance has been about 1/2 to 1/3 the speed as using >>shapefiles on a RAID device.

Message-ID: Ed; If I'm understanding your intent properly, what you'd like to do is composite the hillshade into a second image to give the second image the relief effect shown in the hillshade. I'm not sure about using the OFFSITE parameter or using an alpha channel. The way I've done this before is to get a brightness factor (greyscale value / 256) to get a floating point value between 0-1.0. Then multiply each color channel of a 24 bit image by the brightness factor to get an integer between 0-255, and combine the new R,G, & B channels into a 24 bit image. Then you'd have to drop the 24 bit image to 8 bit paletted for use in MapServer. This was done in a GIS using grid datasets; I don't know if there's any C code out there to do the same thing.

Do the WIDTH and HEIGHT properties of your IMG tag (for displaying the map) match the SIZE parameter in your MAP file? For example, your template file might have: and your MAP file include the line SIZE 600 600 This will cause MapServer to generate a 600x600 pixel image that the client's browser will squeeze into a 400x400 pixel display. Depending on the values involved, the result can look rather "normal" and you wouldn't see a problem. But the scale will be wrong because the browser is resizing the image without MapServer's knowledge. - Ed Ed McNierney Chief Mapmaker TopoZone.com (978) 251-4242 -----Original Message----- From: Claude Philipona [mailto:claude.philipona at skirando.ch] Sent: Wednesday, July 11, 2001 4:52 AM To: mapserver-users at lists.gis.umn.edu Subject: [mapserver-users] Scale calculation I don't quite understand how scale are calculated.

I don't know if the slowdown is the communication between SDE and Oracle, the extra hop to the Oracle machine, or just SDE itself. Beyond the speed issue, every once in a while I would get an error trying to access SDE layers, but only when trying to access the larger layers (in filesize): msSDELayerNextShape(): SDE error.

This seems to occur for the larger datasets (ex: a shapefile of size: 12.6 MB .shp, 4.5 MB .dbf took on average 10.5 seconds to access for an SDE layer; 2.6 seconds for a shapefile) For the smaller datasets and especially at smaller scales, the difference between them is less. (ex: a shapefile of size: 294 KB .shp, 419 KB .dbf took an average of 1.7 seconds for the SDE layer, and 1.3 seconds for the shapefile.) I don't know if the slowdown is the communication between SDE and Oracle, the extra hop to the Oracle machine, or just SDE itself.

I finally isolated the problem: embedded scalebars. For exemple, given the following mapfile: # Map file NAME "NEF" STATUS ON SIZE 540 360 SYMBOLSET"C:\web\htdocs\dev\geodata\symbols\marker.sym" FONTSET "C:\web\htdocs\dev\geodata\symbols\fontset.sym" EXTENT 278263 5031185 290820 5041061 UNITS METERS SHAPEPATH "../../../mapdata" IMAGECOLOR 220 220 175 # Web definition WEB IMAGEPATH "c:\web\htdocs\tmp\" IMAGEURL "/tmp/" LOG "demo.log" END # Scalebar SCALEBAR IMAGECOLOR 0 0 0 STYLE 0 COLOR 0 0 0 BACKGROUNDCOLOR 255 255 255 OUTLINECOLOR 0 0 0 LABEL TYPE BITMAP SIZE SMALL END UNITS KILOMETERS INTERVALS 3 TRANSPARENT TRUE STATUS EMBED POSITION LC END # Layer definitions LAYER NAME "nef1995" TYPE POLYGON STATUS ON DATA c1995 CLASSITEM "valeurnef" CLASS EXPRESSION /./ OUTLINECOLOR 255 255 255 COLOR 255 255 255 END END END # of mapfile ...I get the following error: Fatal error: MapServer Error in msGetBitmapFont(): Invalid bitmap font.

Strangely, the mapfile was OK with version 3.4. Any solution? Also, the 3.5 mapfile specs says the you need to define a markerset in order to embed a scalebar. But embedded scalebars were working fine in 3.4 even if there was no markerset defined anywhere. Could somebody give more informations about all this?

This is only true however if the SDE and Oracle instances are tuned AND your requests is limited in extent (i.e., don't try to draw all the contours for the state of Virginia when zoomed all the way out). If your view window is of reasonable size SDE will smoke -- assuming things are tuned correctly. It makes sense if you think about the process. If you ask a database for the ALL the records you need to go through the DB, SDE blah blah and it would probably be easier to get a single file. However, if you only want a few records (i.e., spatial features) a DB can consult an index, search it very fast and return your request. I think the same idea can be used for small data sets. Do I really need to go through the DB/SDE etc. for the county boundaries? Probably not.... I'm curious how you have SDE on a Linux Box? Did you get a pre-release or something? The tuning comes in many levels. These range from hardware (e.g., RAID configurations, network hardware) to Oracle (about a million setting here) and SDE (i.e., grid tiling mostly). Each SDE layer needs to be tuned separately. It's a bit of a pain but it needs to be done. Don't use the GUI Arc Loaders---use the command line SDE tools. On ESRI's website you can get the SDELoader/SDEMonitor utils to help with tuning a bit. As for the error I haven't seen that one. I'm still having a few issues with queries against SDE from ms but....none exactly like that. -----Original Message----- From: Andrea Goethals [mailto:andreag at geoplan.ufl.edu] Sent: Tuesday, July 10, 2001 1:23 PM To: mapserver-users at lists.gis.umn.edu Subject: [mapserver-users] SDE performance and error I thought the posting the other day about the performance of PostGIS vs shapefiles was interesting. >>The PostGIS performance has been about 1/2 to 1/3 the speed as using >>shapefiles on a RAID device.

The server will propose a large set of raster map from 1:25'000 to 1:1'000'000. The client web-sites will be able to use the central mapserver to interactivly geocode any kind of information (points, lines, surfaces) using an applet and to visualize and to navigate thru the obtained geocoded objects. Each site using Mapserver is totally independent should be able to integrate the map directly (no frames).In this configuration we don't have a web borwser making direct request to MapServer, but rather the web server machines would have to make the cartogrphic request to the mapserver machine. This is a kind of wms. My question: What is the best solution to implement this kind of architecture? Has anybody already done such thing? My ideas were to use WDDX (Web Distributed Data Exchange, http://www.openwddx.org/faq/) to exchange the required parameters between the mapserver box (coordinates of the click, shapes ON,...) and the webserver boxes (url of the map image,...). So the Webserver (php enabled) would post a wddx file (containing the serailzed parameter) to the MapServerPHP-MapScript. After deserialization PHP/Mapscript will process the map request and return wddx file (containing the url of the images and other important parameter). Is it the way to go to get good performance? Is there a better way to do it? Other question: I was palnning to start this development using directly Mapserver 3.5, providing that the system will not enter in production before november. Is 3.5 stable enough? Any timesacle for the official release?

I had explicitly told PHP to compile with GD 1.2 but noticed that the configure stated that it did not have GIF support. This was because I had originally compiled PHP with GD 1.8 and did not remove the config.cache file. Once I deleted the config.cache and reran configure and compiled and installed PHP and apache everything is now working. Now its time to learn how to use mapserver and PHP/mapscript to create a layer and draw symbols that can be queried at locations from a postgresql database. Any examples would be a great time saver Again thanks for the help.

Is this working with the current CVS source for MapServer or older packaged source? The older configure logic was somewhat flackey, but I thought it was currently pretty bulletproof. I also tried with gdal 1.1.4 and the current CVS source. Both seemed to configure alright, though I see that MapServer CVS requires GDAL CVS, since the GDAL 1.1.4 OGR support lacks a feature now required by MapServer. I will prepare a GDAL/OGR 1.1.5 release soon to coincide with MapServer 3.5. If you can provide more details on your configure problem perhaps there is still something that needs to be fixed.

Nacionales) Date: Fri, 13 Jul 2001 18:02:05 +0100 Subject: [mapserver-users] New User - Projection Question In-Reply-To: Message-ID: Hi there. I don't use Proj.4 myself so I can't help you directly. However, I can give you a little advice. First you need to know what projection these datasets are in. If they have different projections then you might want to standardize. For the Continental US, the common projection systems are Lambert Azimuthal Equal-Area, and Albers. From what you're saying, it sounds like your datasets are unprojected--in geographic coordinates. You can certainly use PROJ.4 and reproject on-the-fly in MapServer. However, I'd recommend you reproject your datasets to one of the projections mentioned above. In either case, here's the standard Continental US parameters for Lambert Azimuthal Equal-Area projection: Ellipsoid (Spheriod): Clarke 1866 Central Meridian: -100 (100 degrees West) Reference Latitude: 45 Units: Meters And here's the parameters for Albers Equal-Area Conic: Ellipsoid/Spheroid: Clarke 1866 Central Meridian: -96 Ref Latitude: 37.5 Standard Parallel 1: 29.5 Standard Parallel 2: 45.5 False Easting: 0 False Northing: 0 If you want to use PROJ.4, look at the PROJ.4 documentation for proper syntax use. Also, look at the MapServer docs at http://mapserver.gis.umn.edu/coordinates.html.

I want to use SDL's mapplet the way it is used in Landview. Click or click and drag, release the mouse button, and boom... get a fresh map. I simply can't fathom how to accomplish this. I can click or click and drag to get the red box, but then I have to press the submit button to submit the form actually. How do I activate the boolean 'redraw'? 2. How do I enable the swap method? that is, refresh only the image not the page? 3. How do I enable the pan buttons (and any other buttons, for that matter). Do I form.submit() onClick? 4. How do I have the results of a query (or nquery) be displayed in a specific frame? For example, if I want to create a frames application so the results are displayed in the bottom frame. I have studied the landview source, but that code is so complicated for me, a Javascript newbie, that my eyes are swimming. If I can accomplish the above, I would be happy to put together a doc or even templates that allow others to accomplish the same easily. Another question -- Landview performance is really, really nice. What's the trick? I am using a PIII / 800+ MHz with 256 Mb RAM on a Win2k box with Apache 1.3.20; not great, but not too shabby. But the performance sucks (a few hundred MBs of shapefiles). Is that not good enough? Is the mapserver more responsive on a *nix box? What are the specs of the box running landview?

The shapefiles that you see in the Species application are all in the Lambert Conforml Conic (LCC) projection. From your description of your data I would guess that your data is in generic lat/longs (a 'Geographic' projection). A solution to your problem could be to specify LCC as your default projection in your mapfile, through a PROJECTION object, and then declare 'Geographic' as the layer(s) projection: eg. # Main map and default projection definition # PROJECTION "proj=lcc" "ellps=GRS80" "lat_0=49" "lon_0=-95" "lat_1=49" "lat_2=77" END ... LAYER NAME States DESCRIPTION "States_poly" TYPE POLYGON STATUS ON DATA bounds # Specify the data's projection PROJECTION geographic END ... CLASS ... END END # Layer Declaring 'PROJECTION geographic END' in each layer will re-project your data to the default projection that you specify in the PROJECTION object. I hope this helps you, good luck.

Hopefully, lots of people will get annoyed with the errors in this e-mail that I am proposing and they will correct me for your benefit. I for one am very interested in the outcomes of your project as I will have to look into something similar soon. The Open GIS came up with a standard for accessing data across the web. (I think that the OpenIGS is called something different now but I'm not sure.) One of the commands is something like getimage(). I believe that mapserver version 3.5 has the ability to handle Open GIS capabilities. I seem to remember earlier versions having the getimage() command but I'm not sure about that either. You could use the getimage() command to each of your mapservers and they should return an image. You could then build these images on top of each other, if they are transparent, to make a final map. GD can do this if mapserver doesn't already have a command to do it. You may have to make more that one call to each map server as the order of the layers may be important to your final map. I think that there is a similar OpenGIS command to get information about a layer from a remote map server. It may be something like getinfo(). This is probably a more simpler command as it may only need information from one mapserver. I would *strongly* recommend that you use the OpenGIS standard as a lot of work has gone into this standard and you will greatly benefit from their detailed efforts. I worked on a system of connecting to many map producing servers a long time ago and it was full of problems therefore, we stopped doing it. Since then, the OpenGIS has addressed those problems in their work. Good luck and please keep this list aware of what you are doing. I want to build on your work if you don't mind me "borrowing" your intellectual property and code. ;--) John > -----Original Message----- > From: Claude Philipona [SMTP:claude.philipona at camptocamp.com] > Sent: Friday, July 13, 2001 8:38 PM > To: mapserver-users at lists.gis.umn.edu > Subject: [mapserver-users] mapserver architecture for multi-websites > on several machines > > We are starting a project using Mapserver (PHP/MapScript) for building a > cartographic server which could be used by different client web-sites on > different machines.

(QUERY):(149) Benoit, You are likely getting this because you're using MapServer 3.5 with the demo for version 3.4. The QUERY identifier (in the .map file) is gone in version 3.5 You can either install and use MapServer version 3.4, or use the 3.5 demo that was posted by Steve Lime on the list a few days ago: http://maps.dnr.state.mn.us/mapserver_demos/itasca.tar.gz -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

So you'll have to find out the extents of your DGN files and set the mapfile extents. About tiles, the OGR link will not currently support tiles the way we are used to see them with MapServer. This could be added (after 3.5) if there is enough demand for it, but at the moment the only type of tiled data that the OGR link supports is MapInfo "Seamless layers". -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

As John wrote, the WMS spec includes 3 types of request: - getCapabilities returns an XML document with list of layers and features supported by the server. - getMap returns an image of the map with specified layers and BBOX - getFeatureInfo is used for querying the map obtained from a previous getMap request. One more thing you'll need is a server application that can integrate layers from several remote servers and return a single map image to the client browser... this is referred to by the OGC WMT (Web Mapping Testbed) group as a "cascading server" (well, technically a cascading WMS serves maps to other WMS servers and not directly to browsers... so maybe we should just say WMS client and not cascading server). Anyway, this is not available in MapServer yet but we will be adding this to Mapserver in the next few months. Note that some people have implemented JavaScript WMS clients that combine the WMS maps directly in the web browser, and that might do the trick for you... perhaps those who have developed this kind of WMS clients can comment more.

Like John, I would strongly recommend the use of WMS for this type of project as it fits precicely the scenario that you have outlined below. Just for clarity, WMS specifications outline three functions for standard communications among servers: Get Capabilities Get Map Get Feature Info If I'm not mistaken, I believe these are all requested through http requests. Get Capabilities allows a server to ask a WMS MapServer information such as version compliance, layers availability, etc... This is used to make further requests for the map and attribute information. Get Map returns a map based on information passed as parameters. This includes projection info, extents, selected layers, etc... At this time symbology is not included so this has to be prepared beforehand. Get Feature Info returns attribute information for a selected point and selected layer(s) in XML format. Currently in MapServer 3.5, WMS compliance has been completed so that MapServer is capabable of responding to WMS requests. Documentation for use of WMS should be published shortly. Under development is the ability for MapServer to "Cascade". This is the ability to call multiple servers through WMS and overlay resulting maps to return a single image to the end-client. Images are overlayed by setting all pixels in each image where no data is found to transparent so that layers beneath can be seen. This will be completed through the end of this summer. I hope that helps clear up what to expect somewhat. If I'm mistaken in some of the technical details, please someone correct me. Look for a lot more information to be available concerning WMS in the coming weeks.

What you see below is all there is at the moment. First of all there is virtually no difference in performance no matter what format you choose. The N option writes indexes as I originally wrote the code, this produced machine dependent files. The L and M options write an index that is portable and you should choose the byte ordering that matches your environment best. The last couple of options tag a bit more information into the index including a magic number so that apps could test for this type of file. The hard part is setting depth (i.e. the amount of detail in the quadtree). If depth is set to 0 then a depth is automatically calculated to try and store 8 features per node. I've not run across any rules for what a good value is. I generally just experiment with a few values between 4 and 10 and see how things run.

As MapServer does not (yet) support WMS connections, one may use MapServer along with the mapplet developed by Steve to display maps using a WMS provider. At a high level: - add another parameter to the mapplet's interface which has a WMS GetMap request, i.e.; - create a wrapper CGI script to ingest the WMS request output and display it through the mapplet (Java does not allow for connections to remote servers); - add modifications to Java code to handle additional image objects (i.e. getImage and drawImage); You can then use JavaScript to manipulate the layer information (on/off, etc.), and updating the WMS request as needed, adding your own MapServer CGI variables. More info is available at: http://www.kralidis.ca/gis/mapserv/mapplet/howto.htm I'd be interested to hear other approaches...

This is because shapefiles can contain only one geometry type at a time, and ogr2ogr defaults to use the geometry type of the first shape it encounters. I'm really not an expert with OGR2OGR, but I think what you need to do is force the type of the output file, and use the -skipfailures option to prevent the execution from aborting when incompatible geometries are encountered: ./ogr2ogr -skipfailures -f "ESRI Shapefile" output_point 782221.dgn \ -lco SHPT=POINT ./ogr2ogr -skipfailures -f "ESRI Shapefile" output_line 782221.dgn \ -lco SHPT=ARC ./ogr2ogr -skipfailures -f "ESRI Shapefile" output_poly 782221.dgn \ -lco SHPT=POLYGON The -lco switch is to pass layer creation options which are format-specific... in the case of shapefiles, the SHPT layer creation option specifies the type of shapefile to create.

This happens on both Windows and Unix. We are going to look into this, but in the meantime, you should avoid using the PHP/MapScript module with PHP 4.0.6 ... you can use PHP 4.0.4pl1 or 4.0.5 which were both working fine. Note that backtracking to older versions of MapServers such as 3.4 or 3.3.011 with PHP 4.0.6 is not likely to resolve the problem. -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

The shapefiles that you see in the Species application are all in the Lambert Conforml Conic (LCC) projection. From your description of your data I would guess that your data is in generic lat/longs (a 'Geographic' projection). A solution to your problem could be to specify LCC as your default projection in your mapfile, through a PROJECTION object, and then declare 'Geographic' as the layer(s) projection: eg. # Main map and default projection definition # PROJECTION "proj=lcc" "ellps=GRS80" "lat_0=49" "lon_0=-95" "lat_1=49" "lat_2=77" END ... LAYER NAME States DESCRIPTION "States_poly" TYPE POLYGON STATUS ON DATA bounds # Specify the data's projection PROJECTION geographic END ... CLASS ... END END # Layer Declaring 'PROJECTION geographic END' in each layer will re-project your data to the default projection that you specify in the PROJECTION object. I hope this helps you, good luck.

A few more questions: > > - is OGC WMS also supported in PHP/Mapscript (source comming from the nightly > build) or only in the cgi version? The 'mapserv' CGI executable will automagically detect if it is receiving a WMS request based on the URL parameters and will behave as a WMS server if it receives a WMS request. There is nothing in MapScript related to WMS... WMS is just a standardized set of CGI parameters (and related behaviors) to use in communicating with a map server and MapServer knows how to respond to these CGI parameters. > - if yes, where how can we use the different getCapabilities, getMap, > getFeature wiht PHP/Mapscript. MapServer cannot yet act as a WMS client (but this is coming as I wrote earlier), so at the moment you would have to build WMS URLs yourself in PHP, call the remote WMS servers via HTTP protocol, and combine the returned images using the GD PHP package or an equivalent tool. > - where can i find a little more documentation or examples on how to use OGC > WMS with Mapserver and PHP/Mapscript? > There is not much documentation on how to use MapServer as a WMS at the moment. We're working on a WMS HOWTO that should be ready in the next week or two. The best for you is probably to wait for this HOWTO to become available.

I guess the error message should be more explicit, but what it means is that configure looked for all the following files: ogr_feature.h, ogrsf_fmrts.h, cpl_conv.h, ogr.a, ogrsf_frmts.a, cpl.a and at least one of them could not be found. It is likely that you had not yet compiled the OGR tree at the time you ran configure and one of the .a files was not found. Was it the case? As Rob noted, there are several ways to compile GDAL/OGR independently or not in MapServer and perhaps that's not well enough documented (if at all!?!): 1- OGR only statically linked into MapServer, then you point configure directly to the ogr source tree after having compiled OGR: configure --with-ogr=/path/to/ogr/source 2- GDAL only using libgdal.so installed in system lib dirs, this assumes you have previously run 'make install' as root in your GDAL source tree: configure --with-gdal or configure --with-gdal=/usr/local/bin/gdal-config (or whatever the path to the installed gdal-config script is.) 3- GDAL and OGR using libgdal.so. Same as #2 above, but add --with-ogr with no argument: configure --with-gdal --with-ogr or configure --with-gdal=/usr/local/bin/gdal-config --with-ogr I'll copy these notes in the README.CONFIGURE I hope that helps. -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

I have shape files in my C:\Inetpub\wwwroot directory called gaslines. They work fine with ESRI's products. However, I have set up a simple test to use these shape files, but with no success. The legend and scalebar png's are being produced, but the shape file image isn't. I've checked the output directory and the legend and scalebar images are there, but the shape file image isn't (e.g. there are file names like "testingleg333.png" and "testingsb333.png" but no "testing.png") I have tried moving the shape files to different directories (all web-accessible) and changing the needed files, but that hasn't worked. Also, there are no errors produced by the mapserver. It comes back with another web page with everything there but the shape file image. Also, the legend image is there but it is empty (obviously, since the mapserver can't seem to find/read the shape files). I also tried running shp2img, and it at least outputs a image, although it is blank (solid white). It produces no errors. Does anyone have any ideas??? They would be greatly appreciated!

Message-ID: Unless you're points are in a shapefile then there's no way for the MapServer to query them. Sounds like what you want to do is take a click from a map and query the SQL database, sort of the reverse of drawing. The code to take an image click and turn it into a map coordinate is available lots of places. You can take that coordinate (ie. lat/lon) and create a SQL statement with it "select * from table where x > minx and x < maxx and y > miny and y < maxy". Where the min and max values are based on the computed map coordinate plus some buffer. That's essentially how point based MapServer queries work anyway. Does that make sense?

Consider this a confirmation to problems with PHP 4.0.6. I backtracked and rebuilt with source from 4.0.5 and I have zero problems! The issues with losing the handle of the map when dynamically generating a map from database contents are gone. I can now reliably (it seems) create a map on a blank .map file using mapscript only to set map/layer/class properties and add additional layers. This works now with the CVS version of Mapserver, Gdal and PHP 4.0.5 on my end.

(I > recognize the difficulty, however -- what is a service description > absent a map file? Perhaps a simple wrapper example could be bundled.) 2-parts answer: 1- No it does not violate the spec... at first sight it seems like it would, but there was a discussion this recently on one of the WMT mailing list that made me realize that the following is a valid onlineResource URL and does not violate the spec: http://my.host.com/cgi-bin/mapserv?map=/path/to/demo.map& Basically the rule is that the OnlineResource URL has to contain a trailing "?" or "&" so that the client is ready to append parameters to it. It is also recommended that clients check for the presence of the trailing "?" or "&" and try to be smart and add one in case it is omitted since several servers (including the first ones we did setup) tend to not include it even though it is required. 2- However, I prefer not pushing my luck, so I usually setup a wrapper shell script that sets the MS_MAPFILE environment variable and then passes control to the mapserv executable... that results on a cleaner OnlineResource URL. #! /bin/sh MS_MAPFILE=/path/to/demo.map export MS_MAPFILE /path/to/mapserv I'll have this included in the WMS HOWTO as well. BTW, for those interested in discussing WMS issues, a public mailing list has been started recently and lots of interesting stuff is discussed there: http://www.intl-interfaces.net/mailman/listinfo/wms-dev -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

Below are my current tested versions/builds and the problems with them. The system is FreeBSD 4.2 RELEASE and all of the below use Apache 1.3.19 with PHP as a module. ========================== GDAL 1.1.14 from the website or GDAL CVS (1 week ago) MapServer 3.4 or 3.5 from nightly or CVS (1 week ago) compiled as PHP module -I cannot get OGR to statically link into the MapServer module without GDAL. This isn't a problem for me specifically, but issues have been reported. I CAN --enable-ogr with no path if I have GDAL properly setup.

When adding or accessing layers you will receive a message "Object has invalid _handle_ property. I've tested this using Mapserver 3.4, and 3.5 nightly and CVS. -Scale bar cannot be embedded in the .map with a map definition or MapScript -Plain maps with little modification in mapscript and no scalebar or logo images seem to work. I have not tested querying layers, but basic draw with pan/zoom works well. ========================== GDAL 1.1.14 from the website or GDAL CVS (1 week ago) MapServer 3.5 from nightly or CVS (1 week ago) compiled as PHP module Proj 4.4.3 PHP 4.0.5 -Layers draw fine when using a map definition but when drawing a layer from within PHP/Mapscript lines look to be drawn as points only. So a polygon will only be drawn as the points within the polygons and lines between points are NOT drawn. -There are issues with setting color properties of layers as well. The "color" attribute of a layer ONLY changes a polygon's outline color instead of it's fill. Also, I can ONLY get the base "color" attribute to change how the map appears. Setting any of the other attributes (backgroundcolor, outlinecolor, etc. etc.) makes no changes to the map. BEST COMBO SO FAR! ========================== GDAL CVS (1 week ago) MapServer 3.4 compiled as PHP module Proj 4.4.3 PHP 4.0.5 -I have not found any goofy issues with this one yet. Layers draw properly from a map or Mapscript. Scalebars can be properly embedded, and colors are back! YAY! I'll keep you posted! Hope someone finds this useful!

I could use this functionality, too. The server already has the capability of recognizing MAXSCALE and MINSCALE in the .map files. It seems these could easily be coordinated, such that these properties could be exported to the capabilities statement and thus would be respected if provided in the .map file. So I think this is an easy thing to do if you don't treat scalehint as pure metadata but is derived from MINSCALE MAXSCALE. Doug. > PS - Doesn't requiring the 'map' parameter violate the WMS spec?

We have a software suite able to access OGC Web Map Server, Web Feature Server, LDAP etc as well as ancilliary services such as Gazetteer, Catalog, Geocoder, Geoparser (text analysis). This software suite is embedded in JSP pages in servers such as Tomcat, Jrun, etc and resolves all the hairy issues of matching complex and varied configurations of remote services into simple views that lightweight HTML pages and Applets can cope with. Many of the above services are proto-specifications and we have been active in the development of them. We will be in a position to widely distribute our package once those specs are finally published and the various services can be implemented properly by mapserver, ArcIMS etc etc. For more details please see http://webmap.socialchange.net.au We aim to make our software suite free for community groups, but have been forced to wait until mapserver technology arrived and Tomcat etc to have an environment to deploy into. Any help with resourcing our aim to provide free access and support for the community would be extremely helpful in fast tracking that. In the meantime, please contact us if you have a requirement we can help with.

A URL prefix is defined as an opaque string including the protocol, hostname, optional port number, path, a question mark '?', and, optionally, one or more server-specific parameters ending in an ampersand '&'. The prefix uniquely identifies the particular service instance. A client appends the necessary request parameters as name/value pairs in the form "name=value&". The resulting URL must be valid according to the HTTP Common Gateway Interface (CGI) standard[16], which mandates the presence of '?' before the sequence of query parameters and the '&' between each parameter. As with all CGI applications, the query URL is encoded[12] to protect special characters. The URL prefix must end in either a '?' (in the absence of additional server-specific parameters) or a '&'. In practice, however, Clients should be prepared to add a necessary trailing '?' or '&' before appending the Operation parameters defined in this specification in order to construct a valid request URL. Note that for servers that want to support the POST method, using "?map=...&" as part of the online resource URL is not legal... it is OK only with the GET method. > I got around this by using the "setenvif" feature of apache ...

Could you please specify the risk? If there is a problem (other than the absence of the ScaleHint in the capabilities) I would like to address it.

Is it possible for a script written in mapscript to interact with the mapserver cgi? If it is, in what way? and how? I'm kinda confused about this point, and I don't know if i need to write the scripts and forget about the mapserv CGI or make them interact. My application needs to add layers to an already displayed map based on a two points query. That is, the user clicks over one point, then over a second point and then i should, based on what points the user clicked on, display another layer on top of the map. >From what i've seen this isn't possible using only the template file, mainly because the cgi 'sumbits' itself at the first click over the map zone, am I wrong?

Message-ID: MapScript and MapServer CGI are not generally used together. MapScript gives you the tools to build custom versions of the CGI that better suit your needs. The CGI versions provides a lot of out-of-the-box functionality. The CGI version is not equipted to handle mutliple query points. It can handle a box as input. Standard HTML forms are not capable of doing what you want so you'll have to look at custom client pieces (via java, dhtml,...) too.

Is it possible for a script written in mapscript to interact with the mapserver cgi? If it is, in what way? and how? I'm kinda confused about this point, and I don't know if i need to write the scripts and forget about the mapserv CGI or make them interact. My application needs to add layers to an already displayed map based on a two points query. That is, the user clicks over one point, then over a second point and then i should, based on what points the user clicked on, display another layer on top of the map. >From what i've seen this isn't possible using only the template file, mainly because the cgi 'sumbits' itself at the first click over the map zone, am I wrong?

The WMS spec allows vendor specific parameters to be used, and it also allows fixed parameters to be included inthe URL root eg this is a valid service URI: http://mymaps.com/mapserver?map=topo The "unit of address" is the LAYER - if you have multiple configuration files and have to negotiate which layer is being used then sure, you have to implement your own under-the-hood mapping to identify the map file. Since map files are the source of capabilities documents though (correct?) it seems logical to define each map file/script binding as a service with its unique serviceURI Rob Atkinson "Doyon, Jean-Francois" wrote: > OK, it's this simple: > > Make sure you have the module mod_setenvif enabled or compiled into your > apache and setup a line like follows in your httpd.conf: > > SetEnvIfNoCase Request_URI "/cgi-bin/atlasogcmapper" > MS_MAPFILE=/home/mapdata/nac/wms.map > > That's it! > > Although I've never tried it with Apache on NT, I see no reason why it > wouldn't work. > > Hope this helps, > J.F. > > > ---------- > > From: Paul Ramsey[SMTP:pramsey at refractions.net] > > Sent: Wednesday, July 18, 2001 5:51 PM > > To: Doyon, Jean-Francois > > Subject: Re: [mapserver-users] ScaleHint > > > > It would make more sense with an httpd.conf fragment, but I get the gist > > of it... :) > > > > "Doyon, Jean-Francois" wrote: > > > > > > > > PS - Doesn't requiring the 'map' parameter violate the WMS spec?

Message-ID: It hits every output pixel anyway when resampling as you suggest. Actually all that happens with OFFSITE or raster classes is that changes to the default lookup table are made. So for each pixel the raw value is translated to a color index in the output image. OFFSITE pixels aren't even considered. Actually it's marginally faster to use OFFSITE since it skips an assignment statement and the test has to happen on all pixels. That said, no overlap is certainly better since no output pixels would be assigned values twice. I guess it depends on the amount of overlap you're talking about removing.

Try using the following configure option: --with-gd=static,/path/to/gd-1.8.4 This will explicitly link with /path/to/gd-1.8.4/libgd.a instead of using -lgd which would search your library path and may find the wrong library.

I've been experiencing similar problems trying to compile GD1.8.4 from source with Freetype2 ... things did compile and I'm convinced that the right copy of the lib was loaded, but I couldn't load any TTF font in MapServer. That was using the GD1.8.4 source code with the Freetype2 that comes preinstalled on RH7.1 ... I never had time to figure out the problem but it seemed to me like I had not built the GD+freetype combination properly.

Ed, The drawGDAL and drawTIFF cases in mapraster.c are effectively always checking for offsite values whether you set it or not, so the answer to your questions is that no ... MapServer does not incur any significant performance cost when you use offsite values.

If I change the layer to be a LINE, mapserv displays a dot, unzoomable. Here's my map file: # # Start of map file # NAME BUSES SIZE 600 600 SYMBOLSET ./symbols/symbols.sym EXTENT -71.812301 -33.413659 -71.18889 -33.04636 UNITS METERS SHAPEPATH "buses" IMAGECOLOR 255 255 255 PROJECTION "proj=utm" "ellps=GRS80" "zone=19" "south" "no_defs" END # # Start of web interface definition # WEB HEADER buses_h.html TEMPLATE buses.html FOOTER buses_f.html MINSCALE 1000 MAXSCALE 1550000 IMAGEPATH "/var/www/html/ms_demo/tmp/" IMAGEURL "/tmp/" LOG "buses.log" END # # Start of scalebar # SCALEBAR [yadda yadda yadda] END # # Start of layer definitions # LAYER NAME r_bus5 TYPE POLYLINE STATUS DEFAULT DATA r_bus5 CLASS COLOR 100 150 54 END END END # Map File -- V.

The 2 different ways were to: 1. Install the freetype-devel RPM then build the other things 2. Use Apachetoolbox (ATB)(this is what I do pretty much all the time now). ApacheToolbox can be obtained from: http://www.apachetoolbox.com and it's a REAL time saver. My standard methodology has been to download the (ATB) script only, run it selecting the options I want to compile into Apache, and then compile Apache. GD, PHP, etc. are all options. I seem to remember having one mild issue with compiling in GD/TTF support---maybe I need to install Latex first?? I did so with an RPM and things compiled fine. Give it a try I think you'll find it useful.

Try using the following configure option: --with-gd=static,/path/to/gd-1.8.4 This will explicitly link with /path/to/gd-1.8.4/libgd.a instead of using -lgd which would search your library path and may find the wrong library. If that doesn't work, then you may be in the same boat as me... I've been experiencing similar problems trying to compile GD1.8.4 from source with Freetype2 ... things did compile and I'm convinced that the right copy of the lib was loaded, but I couldn't load any TTF font in MapServer. That was using the GD1.8.4 source code with the Freetype2 that comes preinstalled on RH7.1 ... I never had time to figure out the problem but it seemed to me like I had not built the GD+freetype combination properly. So I just decided to fallback to the GD1.8.4 RPM that is distributed with RH7.1 But if anyone figures it out or gets that combination working then I would apreciate hearing about what they did. -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

Things seem to be working fine for us now with PHP 4.0.6 and MapScript, so please let us know if you notice any more problems with this combination. BTW, this fix in the latest MapServer 3.5 may result in (minor) memory leaks with versions older than PHP4.0.6 since our problem was a side-effect of a memory leak fix in PHP4.0.6. So it is recommended that if you compile/install the latest MapScript 3.5 from CVS then you also upgrade to PHP 4.0.6 Note that the PHP3 version (does anyone still use it anyway?) was not affected at all by these problems. And BTW, No we won't publish a new 3.4 release with this fixed, but if you want to upgrade to PHP4.0.6 with MapScript 3.4 then you can add a call to zend_list_addref() after the add_property_resource() call in phpms_object_init() around line 594 in php_mapscript_util.c: add_property_resource(return_value, "_handle_", handle_id); zend_list_addref(handle_id); Best Regards, -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

I hadn't thought of reprojecting, but that's a possiblity. A few applications that I can think of off the top of my head. First is GPS tracking applications where you may "follow" a vehicle. The vehicle is always centered within the extent and always oriented to the top of the map with the map rotating as direction changes. Additionally, sometimes coverages are better displayed with a specific feature at map top rather than true North. For example, a map of ski runs on the North face of a mountain. Just doesn't seem right to ski from bottom to top :) It's not a big issue, and I'm sure you have a million things on your plate. Just an idea. Thanks for listening!

Would you prefer a meeting/workshop at the University of Minnesota, Twin Cities Campus (I remember those fine "gopher server" meetings) or something done in conjunction with a related conference? The former is easier to plan and could be pulled off with much less lead time, the latter might be easier for people to justify travel to. That's all we want to know at the moment. If there seems to be interest, we will move forward with your help. You may respond to the group (please keep "Meeting" in the subject) or directly to me.

PostGIS/PostgreSQL is a spatial database much like ESRI's SDE and Oracles OracleSpatial. PostGIS/PostgreSQL includes the following functionality: - Simple Features as defined by the OpenGIS Consortium (OGC) - Support for Well-Known Text and Well-Known Binary representations of GIS objects - Fast spatial indexing using GiST - Geospatial analysis functions - PostgreSQL JDBC extension objects corresponding to the geometries - Support for OGC access functions as defined by the Simple Features Specification The 0.5 release of PostGIS includes support for the MapServer internet web mapping server from the University of Minnesota (http://mapserver.gis.umn.edu). Download the latest CVS version of MapServer to use PostGIS as a internet web mapping backend. Other changes: - New functions - Dimension() - GeometryType() - Envelope() - X(), Y(), Z() - NumPoints() - PointN() - ExteriorRing() - NumInteriorRings() - InteriorRingN() - NumGeometries() - GeometryN() - Length_Spheroid() - Length3D_Spheroid() - AsBinary() + XDR and NDR variants - force_collection() - New Objects - SPHEROID(,,) To be used with the length_spheroid functions for accurate length calculations on lat/lon data. (Thanks to Geographic Data BC and David Skea) - Minor bug fixes - Internal Functions - Extra constructors to make geometry manipulation easier - Structural Reorganization - Broke postgis.c up into four new files postgis_debug.c -- debugging functions postgis_fn.c -- generic functions (like length()) postgis_ops.c -- operators and indexing functions postgis_inout.c -- type support functions and data conversion functions From pramsey at refractions.net Fri Jul 20 17:59:42 2001 From: pramsey at refractions.net (Paul Ramsey) Date: Fri, 20 Jul 2001 17:59:42 -0700 Subject: [mapserver-users] PostGIS as data source Message-ID: <3B58D3FE.2845533E@refractions.net> As announced earlier, PostGIS/PostgreSQL can now be used as a MapServer datasource. You'll need the 3.5 CVS version in order to do it, as well as PostgreSQL. The URL below is an example of a working PostGIS datasource. http://mapserver.refractions.net/cgi-bin/mapserv?map=/home/www/mapserv/maps/postgis.map I have attached the map file used for this example as a template. Mostly, things work just like normal. The only differences are in the connection string (which is just a standard postgresql connection string) and in the way 'FILTER' works: if you want a filter it should be expressed using the kind of syntax you would use for a SQL 'where' clause. I hope some folks give this a try!

What happens when you run the script in offline mode? (ie, from a shell) As a general rule, debugging cgi scripts from web server logs is not at all helpful, because any error that prevents execution will be seen by the web server as a 'Premature end of script headers' (there are no headers because the script never actually produced output).

As for building names, unless you can get this data from city planning, the only thing I can think of that would be close is a ZIP+4 database. Some older ZIP+4 is available online for free, or you can visit USPS website for information about purchasing some of their more current data. As for London, I can't point you anywhere for detailed street data. Of course it exists, but I think most of it is in the hands of city planning departments and some specialized data providers. I'm sure it's available but I wouldn't know where. Hope this helps!

Thanks to all of you who helped with your answers. During this development I mentioned that I wanted to use java script to draw a box on the map instead of an applet because some of our client organisations don't allow Java through their firewalls. Some people asked if I could show them what we did with the javascript to draw the box so I thought that I would post our new site to this list and those who are interested can read the javascript. There are no guarantees that the javascript is readable nor efficient. It just works and that's what I need. ;--) The interface is a Z3950 search of the Australian metadata nodes. We use MapServer to allow the users to define an area on a map that is passed back to the search interface and thus they can do a spatial search. The URL is: http://www.auslig.gov.au/asdd/ click on the "power search" in the top navigation bar and then click on the little image of Australia. This should pop up another window with a MapServer interface in it. Please feel free to play with the search interface. I would like to see if it can handle many hits at once. Thanks again for all your help.

Message-ID: I'm trying to draw individual states, but am having serious problems getting the projection to make any sense. Does anyone have examples I can look at? As an example of my problems, I draw the state of Minnesota. It looks really elongated (since most people are used to seeing it as LCC). So, I do: $map->setProjection("proj=lcc,lat_0=33,lat_1=45,lon_0=-93"); This works, and I get an LCC projection of Minnesota, but only if I redo the extents using the PROJ.4 program. Even then, a good portion of the bottom of the state is lopped off. By playing with the numbers, I discover I can set minx=-1 maxx=1, and the miny and maxy to some value gotten from PROJ4 (+ or - some error so I don't lose the bottom of the state). This doesn't seem right. Since Mapserver automatically recomputes ALL layers (and drawn points) in the new projection, why can't it recompute extents? Or does it, and I'm missing something?

Message-ID: Point labels are subject to the same collision avoidance as other layers. That said there are some special things going on that I don't know if they still make sense. Let me try to explain... My assumption is that with POINT layers that the points (i.e. symbols) themselves are very important and every effort should be made not to obscure them. With POINT layers all points are drawn regardless of overlap and then labels are added. The current rule is that labels can't overlap with each other, nor can they obscure another point. In crowded situations I could see where very few points would get labeled. The alternative would be to allow label/symbol overlap but in testing that results very confusing output since you could label something that itself becomes obscured by another label. The old earthquake mapper I did showed this problem nicely. That's what I implemented the current rule. Reading your message closely you might mean can symbols be shown without overlap? At the moment, no, unless you turn your symbols into labels. Features are always drawn where they are supposed to be drawn. Doesn't mean it couldn't be added though. It would mean adding a marker caching system which wouldn't be trivial but since there's already a label caching system it wouldn't be that hard.

You can apply an extent to an attribute query but that's about it at the moment. That could change in the future by allowing query stacking (ie. query of a query). That said, you can do this in MapScript by doing one query first and then further filtering the results. I believe the database servers do the spatial first then the attribute. They aren't done at the same time, but in sequence.

Message-ID: Here's how it works. Extents are taken to be in the projection defined for the map. There's no way to recompute the extent because there's no way for the software to know what projection it might be in. Hence the assumption. When you do a setProjection you also need to provide extents in the new projection. How are you projecting from old extent to new? Doing just the corners will not work. In 3.5 projection support has been rolled into mapscript. All spatial objects (i.e. shapeObj, rectObj,...) have a project method. You can also define new projections using something like $proj = new projectionObj(string); and can use it in the above mentioned methods.

Does anyone have examples I can look at? As an example of my problems, I draw the state of Minnesota. It looks really elongated (since most people are used to seeing it as LCC). So, I do: $map->setProjection("proj=lcc,lat_0=33,lat_1=45,lon_0=-93"); This works, and I get an LCC projection of Minnesota, but only if I redo the extents using the PROJ.4 program. Even then, a good portion of the bottom of the state is lopped off. By playing with the numbers, I discover I can set minx=-1 maxx=1, and the miny and maxy to some value gotten from PROJ4 (+ or - some error so I don't lose the bottom of the state). This doesn't seem right. Since Mapserver automatically recomputes ALL layers (and drawn points) in the new projection, why can't it recompute extents? Or does it, and I'm missing something?

Me thinks that interval should be based on the output cellsize but 100 seems to work ok. The source is in mapproject.c. Again, if you're using 3.5 you could do something like: $map->setProjection("new output projection"); $latlon = new projectionObj("whatever definition of lat/lon you use"); $map->{extent}->project($latlon, $map->{projection}); At least that's how it's intended to work.

Message-ID: <13858AA1A74F30419F319ACB66A9D122019133@mercator.topozone.com> Mike - You're making the (incorrect) assumption that the minima and maxima of the output projection are related to the minima and maxima of the input projection, and that's not necessarily true. Blue Marble Geographics has a unfixed bug in their GeoTransform DLL because they make the same assumption. I mention their bug because it's a relatively simple illustration. USGS topographic maps (DRGs) are raster maps in the UTM projection. Since each map is bounded by lines of latitude and longitude, the map image is not a rectangle in UTM space. In most cases (all examples here are in the Northern hemisphere) it looks a lot like a rotated rectangle - west of the UTM zone centerline, the maps look like they're rotated clockwise, while east of the centerline, they look like they're rotated counterclockwise. The minimum distortion occurs right at the centerline (the central meridian of the UTM zone) - lines of latitude are indeed perfectly horizontal at the central meridian, and start curving up on either side of it. As a result, the minimum point in UTM space for all USGS DRGs is EITHER the southeast or the southwest corner, depending on whether the DRG is in the western half or the eastern half of the UTM zone, respectively. Since the 1:24,000 and 1:25,000 DRGs are 7.5 minutes each, the central meridian of the UTM zone (an integer degree boundary) is at the right edge or the left edge of the two DRGs that abut it. Since no map ever straddles the centerline, a transformation such as you describe in your email works perfectly. The 1:100,000 DRGs are 1 degree wide and everything's OK. Except.... for the 1:250,000 DRGs. These maps are 1 degree high by 2 degrees wide, and some of them do indeed straddle the centerline of a UTM zone. For example, at 38 degrees North there's a DRG that runs from 98 degrees West to 100 degrees West, crossing the 99-degree-West central meridian of UTM Zone 14. If you look at the original DRG, the map image curves up to the right and left of the centerline. That is, the northern neatline (39 degrees North) is a shallow curve that looks like a smile; the southern neatline is almost identical. And it's that southern neatline (in this example) that jumps up and bites Blue Marble (and you, too). Since the southern neatline looks like a smile, its minimum value is in the MIDDLE OF THE LINE! That is, it's not the southeast corner and it's not the southwest corner. If you try to use Blue Marble's tool to clip the collar from this map, the bottom will be truncated. That's because they presume the minimum output coordinate is the minimum of the projected southeast and the projected southwest corners. But it's not either of those - both of those values are equal and they're too high. To solve this in the general case, you have to reproject EVERYTHING or do some pretty darn clever math. If anyone would like me to email them the 4.5 MB TIFF/LZW file used in this example, let me know (a picture is indeed worth these thousand words). - Ed Ed McNierney Chief Mapmaker TopoZone.com ed at topozone.com (978) 251-4242 -----Original Message----- From: Mike Neuman [mailto:mcn at engarde.com] Sent: Monday, July 23, 2001 3:45 PM To: Stephen Lime; mapserver-users at lists.gis.umn.edu Subject: RE: [mapserver-users] Examples using projection? > How are you projecting from old extent to > new?

With 3.5 you could do this: - a normal point "nquery" setting appropriate tolerances for the spatial query - set a FILTER in the mapfile or dynamically as well The FILTER will be applied before checking the spatial requirement. Note that the FILTER stays set when building a resulting querymap which may not be what you want. However, there's a workaround for that using a cached query to build the image you want.

My guess is that the error you get must be "unable to find php_mapscript_35.dll" and it would be because you put the php_mapscript_35.dll in the wrong directory... usually the Win32 distribution of PHP 4.0.x has extension dlls in the php/extensions dir... so check your php.ini to make sure that extension_dir points to the php/extensions dir in your installation, and put the php_mapscript_35.dll in that directory. -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

I created a highlight layer with "status" to "off". Then, if my url or form contains an id, the status of the highlight layer is set to "on", and $classObj->setexpression("\"$id\"") does the trick... thanks SDL, for pointing out the correct way to quote the expression in one of your emails... not at all clear from the docs. Four questions follow: 1. is the above the most optimal way of doing the above? 2. what about session specificity? way, user1 queries the mapserver with id=1 and that poly gets highlighted, while at the same time user2 queries the mapserver with id=2? are these treated as separate sessions? I am passing the PHPSESSID in the url, btw. 3. how do I zoomin to the highlighted poly? Essentially, I want to find its mapextent, and then feather it by 5% or 10% and then create the map. 4. if I pass a range of ids, say id=1-44, can I - do a sql-ish or regex setexpression so all ids between 1 and 44 light up? - how do I calculate the smallest bounding box that contains all the 44 highlighted polys?

I had a point in polygon search working a month or so ago and now it never selects any points. The only change is that the points are no longer in the same projection. We have the output projection defined at the map level, and I defined the projections for the qlayer and slayer in the layer section. The slayer is in the same projection as the output. Only the qlayer is different. Thanks.

Message-ID: <3B5DD338.4010705@netmeme.org> Hi, I've been developing web-based database applications for several years now -- however, presently, I'm writing (for the first time) one which needs to do dynamic mapping. I'm evaluating MapServer for this purpose (with my preference being to stick with open-sourced, free tools). I need to display maps of city regions with street detail, and layer on top of it data from my own PostgreSQL database (e.g. retail store locations). My stupid newbie question is -- where does one obtain street maps for the U.S. in a form usable by MapServer? Can good street data be obtained for free (e.g. from USGS etc?), or do I need to pay to obtain quality, up-to-date maps? If I need to pay, can anyone recommend any vendors?

Message-ID: I have a line in my php file that reads: $classObj->label->set("type", MS_TRUETYPE); This should be sufficient to set the label's font type to MS_TRUETYPE, and in fact it does, part of the time. The problem comes when I try to call drawLabelCache(). I get an error only SOME of the time, which reads: Fatal error: MapServer Error in msGetBitmapFont(): Invalid bitmap font. Must be one of tiny, small, medium, large or giant. in /usr/local/apache/htdocs/loc-dns/buildmap.php on line 92 Obviously, label->type is getting set to something other than MS_TRUETYPE. I wrote a few msDebug's into maplabel.c to check what was going on. They look like: msDebug("msGetLabelSize: label->type = %d, should be %d\n", label->type, MS_TRUETYPE); Most of the time they read: [Tue Jul 24 12:17:58 2001].858842 msGetLabelSize: label->type = 0, should be 0 (MS_TRUETYPE enumerates to 0, MS_BITMAP enumerates to 1 BTW) But sometimes, after refreshing, I get: [Tue Jul 24 12:17:58 2001].898735 msGetLabelSize: label->type = -2133912937, should be 0 [Tue Jul 24 12:31:51 2001].6434 msGetLabelSize: label->type = 845938944, should be 0 Obviously something is happening to the information in label->type. Could this just be a PHP bug? Also, should the if/else statement really be an if/else if? (else if label->type == MS_BITMAP) =) My source is at http://bludwulf-bsd.dyn.dhs.org/loc-dns/buildmap.phps The mapfile is at http://bludwulf-bsd.dyn.dhs.org/loc-dns/maps/studios.map Refresh a few times or view http://bludwulf-bsd.dyn.dhs.org/loc-dns/index.php and then go back to buildmap.php to see the bug. -Beau Gunderson From v at w.cl Tue Jul 24 13:56:55 2001 From: v at w.cl (Vinko Vrsalovic B.)

I'm not sure about the Perl docs, but if you're using PHP then here is the status of 3.5 documentation: The latest PHP MapScript doc is always in the README file in the mapserver/mapscript/php3 directory of the MapServer source (CVS or nightly build).

I'm new to the Mapserver community. I would agree with this statement from a *technical* point of view, but strongly disagree from an approchability point of view. There are virtually NO examples of how to create maps, do things in mapscript, etc. It took at least 20 hours of me fighting with Mapscript and a .map file before I could get a relatively simple map to display. Then another 8 hours to get the projection right. If I didn't hate my GIS program so much, I probably would have given it up after the first few hours. The documentation has several major errors (queryByPoint still appears on the web site, when queryUsingPoint is correct), PHP Mapscript crashes my webserver when executing simple (and correct, according to the docs) code, and Perl Mapscript coredumps whenever you create a new class in an existing layer or a new layer in an existing map. To get the projection stuff to work as you might expect, I had to upgrade to 3.5. My existing Mapscript code stopped working entirely (with only minor changes made to fix the semantic changes of msSaveImage) by spitting out a blank map, so I had to downgrade to 3.3. Finally, in attempt to debug several things on my own, I downloaded and installed SWIG. Unfortunately, the .i files are no longer compatible with the current version of SWIG.

I agree for the most part. Documentation and examples are definitely *sparse*. I suppose that's because it's much more fun to write code than documentation. I'm hoping that this will all change soon. The MapServer Documentation Project is slowly getting going. Several detailed guides are already available online with more on the way. Examplewise, that is being addressed right now as well at least from the Perl MapScript and MapServer CGI perspective. The MapServer test suite is being re-written for version 3.5 and will include lots of mapscript examples, at least simple ones to demonstrate how to make a map, change projection and execute any of the various query methods. I know I've tended not to share my MapScript code because it's very specific stuff and may be hard to disect without significant amount of explanation. I will post a few more examples running on the DNR site tomorrow. If things don't work as advertised, please let us know! I know you have Mike, but I imagine that many other folks don't. That's what the bugzilla site and the mailing list are for. Complete bug reports are always appreciated (i.e. version, OS, platform, etc...).

There are virtually NO examples of how to create maps, do I wrote the above, and I stand by what I wrote, and yet, I whole-heartedly agree with what you write. I too am frustrated, with my regular web mapping solution, as well as with Mapserver's lack of docs and examples. I waste immense number of hours trying to solve something that has been documented wrong, or not documented at all. Or, the syntax for classes and methods is there, but no real example to wrap my hands around... my current problem is trying to locate a polygon using a polygon id, and then zooming to it... hours and hours of glossing over the miminal docs. But you know what... this is still better than the commercial solution. And while that still leaves Mapserver ways to go, it is really saying a lot. I really do appreciate the un-remunerated work that Steve, Daniel, and others are doing, but we've together _got_ to take this further. Perhaps the users meeting would be a right step. As soon as I get my scripts and maps working, I am gonna make it available to others for what its worth... maybe elementary for some, but might save someone valuable time. Cheers, Puneet.

We have non-geographical datas which are stored in a DBRM, with an ODBC driver. We can access and display them with a short PHP script. As PHP can't be run just after the mapServer's one in the same CGI access to the server, we are looking for short mapScript samples which are displaying DBRM datas according to the clicked polygon-ID. polygon-ID is the primary key in our DB.

There are virtually NO examples of how to create maps, do I wrote the above, and I stand by what I wrote, and yet, I whole-heartedly agree with what you write. I too am frustrated, with my regular web mapping solution, as well as with Mapserver's lack of docs and examples. I waste immense number of hours trying to solve something that has been documented wrong, or not documented at all. Or, the syntax for classes and methods is there, but no real example to wrap my hands around... my current problem is trying to locate a polygon using a polygon id, and then zooming to it... hours and hours of glossing over the miminal docs. But you know what... this is still better than the commercial solution. And while that still leaves Mapserver ways to go, it is really saying a lot. I really do appreciate the un-remunerated work that Steve, Daniel, and others are doing, but we've together _got_ to take this further. Perhaps the users meeting would be a right step. As soon as I get my scripts and maps working, I am gonna make it available to others for what its worth... maybe elementary for some, but might save someone valuable time. Cheers, Puneet.

Ah! Now I can help! :) The problem is that your PHP installation does not recognize ".phtml" as a PHP file extension.

Working with OSS is definitely different, and if you're not used to it, it can seem like a pain. It often requires more work as far as researching, reading docs, trial and error, compiling and re-compiiling and so on. but there are two very big advantages to this: A steep learning curve helps learning. Don't worry, byt the time you're on your third MapServer project, things will neem like second nature. Also, as with most software, usability and simplicity have to be balanced with being featureful. the more features you want, the more complicated to use. I'd rather a complicated software that does everything I need it to properly, than something that looks good but works like crap *cough*windows*cough*. As for the documentation, you landed in a transition period! The MDP is working hard to get decent documentation out there! I've contributed c ouple of documents myself, and intend on doing more. Although I suppose I am partial to them, I'd have to say that they ARE a LOT better than the old series of docs. I *think* I had volunteered to do the MapScript, I'll have to check :) I would recommend everybody look at the MDP page (Linked from the current docs page) for more info and if you're interested to contribute. I think it's important nobody duplicate efforts. As for examples, well, how about some sort of on-line database of resources like that? A place where users themselves could submit snippets of code and mapfiles, could include a description of what it does and so on, maybe even data where legal. Kind of a knowledge-base I guess. then people who did cool new and unsual things with mapserver could share their experience with all of us :) My .02$ !

It is a system by which users can add comments to improve documentation that is posted on a web page. Postgres Database uses this method to update it's manual. It allows users to input corrections immediately as they find them and then every so often the comments get rolled back into the documentation by an editor.

Integrating maps and RDBMS tables is something lots of users try to do and every time we have to explain the process again since none of those who have got this running have shared apps yet. (We're not better... the apps we have that do this we cannot share either! :( OK, back to your specific case: you mention that you already have the PHP code to access the attributes for a given polygon-ID and display them, so you're not too far from a solution. If you look at GMapDumpQueryResults() in gmap75.php3 in our GMap PHP sample app and replace the dbase_...() calls with MySQL calls then you should have exactly what you need. The shapeid obtained from the result object is the polygon-id that you need to access your RDBMS tables. Make sure you look at the version of the GMap scripts demo that matches the version of MapServer that you're using (3.4 or 3.5) since the query-related stuff (and hence GMapDumpQueryResults()) have changed between 3.4 and 3.5. -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

In regards to PHP, please bear in mind that this is a relatively new addition to MapServer - really only getting off the ground in the last year or so. We are working towards improving PHP/MapScript documentation through the UMN documentation project, and I believe this will go a long way to support user development with PHP. On a broader note, remember that this is an open source initiative, and in order for it to be successful requires contributions from the user community. Documentation is now being formally organized through the UMN and I would suggest to anyone who really wants to see this product improve (not just technically, but with all the other supporting components - documentation, samples, bug reporting) to get involved. BTW, I think the user group meeting is a fantastic idea.

References: Message-ID: <3B5EE673.44AD5F28@gis.umn.edu> I'm organizing the documentation efforts at the UMN, so I thought I'd throw in a few comments in the documentation discussion that has been going on. We are getting closer to a complete set of baseline documentation for the basic MapServer software as well as some of the MapScript extensions (thanks Jean-Francois, Steve, Jeff, Ken, and Frank). I think we all agree that documentation is a prerequisite for the official release of MapServer 3.5. Having said that, there is certainly a need for a lot more documentation and examples. One suggestion, is that more people make their source code available so that it can be linked on the gallery page. We have started dividing the gallery up based on the tools used to create the application (let me know if you see any mistakes), and I think a great addition would be links to the code behind the application. More short HOWTOs that describe how to add a simple feature in MapServer (e.g. a JavaScript gui-style interface) would be great. As for including a history of changes to parameters/objects in one set of documentation, I think that may be a bit confusing and difficult to maintain. We are planning to keep older versions of docs available. We should also consider including a summary of the changes from the previous MapServer version in each of the reference documents. Right now, we are using the MapServer bugzilla as a way of tracking errors in documentation. I think will stick with that for now. Perhaps I need to make that more visible on the documentation page. I think that covers it all. Let me know if you'd like to do some writing. I can help with the XML side of things.

I don't have data of that nature. This applies to all query scenarios. Again, if folks have test data they could share... Note that you don't have to define projections for layers that are the same as the output projection. Steve Stephen Lime Internet Applications Analyst Minnesota DNR 500 Lafayette Road St. Paul, MN 55155 651-297-2937 >>> "Michael Anderson" 07/24/01 05:12PM >>> When you are doing a featurequery, do the slayer and qlayer(s) have to be in the same projection? I had a point in polygon search working a month or so ago and now it never selects any points. The only change is that the points are no longer in the same projection. We have the output projection defined at the map level, and I defined the projections for the qlayer and slayer in the layer section. The slayer is in the same projection as the output. Only the qlayer is different. Thanks.

Hello, I'm just specing out the hardware requirements to put togeather a server running MapServer etc. I'm trying to do this on the cheap and the server will initially just be a development server. I'm wondering what the importance of a good video card is when MapServer renders maps. Does Mapserver utilize the video card for this?? If it doesn't then I can go real cheap on this aspect of my system. If it does, are there other considerations in selecting a good card besides for the amount of memory? Thanks in Advance!

Yes bugfixes are often available within a day of being discovered. Yes Mapserver is an amazing package and well worth spending the extra agonizing and frustrating hours to make it work - something Mike's original post noted: MN> Thanks for listening. :-) I do love Mapserver. It's something MN> I've wanted for a long time. However these facts do not negate Mike's observations or the validity of his complaints. Mapserver -is- a bear to setup. It -is- frustrating that you cannot display even a simple map "out of the box". The poor state of the documentation and examples -is- worth addressing. I don't object to what you said, just the tone and target. Yes, everybody should keep in mind that Mapserver is -free- software, and understand that -we- are it's community, and that it is up to -everybody- to address any lacks that are encountered along the way. The original post was not a whine directed solely at the developers, rather an impassioned plea to all who have made progress with Mapserver to share their gains: MN> So, I implore the Mapserver community: Contribute every MN> Mapscript and .map sample file you can find and *put it MN> in the distribution*. Or at least make another distribution MN> (and ms_demo doesn't cut it) that has dozens of examples.

For the past few days I've been working on a new layout that fits our primary site as well as the sub-sites. I have also started a bit of work on two areas specific to Map Server. One, is a user managed Q & A area where users can submit questions or answer existing questions in the database. The second is user contributed Mapscript examples. Both are PHP/mySQL based, categorized and able to house virtually unlimited content once they are complete. I will be posting as much of my own knowledge and experience with Map Server into both of these areas for a start and will turn them loose on the group.

Mapserver makes an image and either dumps it in a tmp directory from where it is served up, or sends it directly to the calling program (standard output). Video card would be important for the user who is browsing the Mapserver website... because the user's computer would have to download and actually render the image. As far as Mapserver is concerned, you could make it headless, that is without any monitor at all, if your OS permitted it.

In mapscript you could manage the classes yourself and create a custom layer on-the-fly with only the requested classes. You could also muck with with class colors or expressions to render them useless. I can easily add a status option to an individual class and can alter the rendering and query code to honor it. I can't quickly add a programatic may to toggle class status from the CGI program. Please add this to Bugzilla as a feature request. - There is a performance hit, how much depends on the data and how many layers you need to break out. For moderately sized datasets and a few additional layers you probably won't notice. On large datasets, if this much control is needed then I would argue that the shapefile itself should be split into different layers.

I hope someone on the list can either guide me to the correct way, or confirm that it is not possible so I stop wasting my time. For simplicity sake, say, I have a parcels layer with an attribute called parcel_id. Given a parcel_id I want that polygon (or polygons, if I have more than one parcel_id), get its extent, and zoom to it. The closest I have gotten is trying to read in the parcel.shp file using ms_newShapeFileObj like so -- $shapeFile = ms_newShapefileObj( "data/parcel", -1 ); which, of course, doesn't work right there... gives me a "Fatal error: Failed to open shapefile data/parcel. Even if I could get the shape file open, I really don't know quite what to do next. I can't really query the shape file with $parcel_id because $parcel_id is an attribute and is really stored in the parcel.dbf. However, parcel.dbf doesn't have any (visible) link between the attribute and the shape file... there must be one... some kind of shape index... what is it? where is it stored? how do I access it? As I said above, at the very least I need to know whether the above is even possible or not. Then I have worry about why I can't open the shape file? then I have to find the link between the shape file and the dbf file for that layer.

You could use multiple images and get at them through an image catalog. 3. You could mosaic them into one large image (could get REALLY big fast--probably not feasible) 4. If pyramid layers/aux/MrSid were supported you use them to display moderate sized mosaics or original imagery (greatly reduce storage footprint but uncomressing hammers CPU cycles). 5.

I've used 2 stratagies here, the image catalog and single images at multiple resolution. Both certainly have their place and work well under the right circumstances. We serve USGS DRGs and DOQs for the entire state (~1200 tiles) using tiled GeoTIFFs. Works great as long as you display at appropriate scales which isn't much of an issue with those datasets since they're only useful over a limited number of scales. The DOQ dataset is about 20Gb, the 3 DRG datasets are about 6Gb. We also have a LandSat TM mosaic. We serve those using a pyramid type system where each reduced resolution image is a layer tied to a scale range. Finally there are the source images that are handled using tiling. Neither LizardTech nor ERMapper (ECW) are forthcoming with anything but Windows APIs so don't look for support there. The ERMapper folks do have a demo out there that uses MapServer on top of their imagery using a plugin they developed. Perhaps JPEG2000 will be ready soon.

It's optional. you can refer to the docs in http://www2.dmsolutions.ca/webtools/php_mapscript/php_mapscript_docs.html and use the perl equivalent for the calls on the methods. hth, -- V.

I bet the OSSIM people have some good insights on this too. Our take has always been that an efficient system is going to have to resort to (5) if they want to display imagary at a large range of scales. If you want to have a large range of scales and you don't re-sample ahead of time, you have to re-sample on the fly, which could be incredibly onerous (open up 100 orthos and grab 10 pixels from each, fun).

What you see on the page referred to above is a township in Wisconsin, USA. There are nine orthorectified photos tiled to produce an aerial image of the entire township. Each one is a 30 meg tif. I tried it the simple way first, just to get it working. I just put each tif in the map file as a separate layer. Seems to work well, but on my 450mhz mapserving machine (x86), it slows down quite a bit as it processes 270 mb of image data. If the viewer is on a slow modem the difference is not so noticable, but on a lan it is significant. One thing I did notice is that as one zooms into the map, the draw time will decrease as the server processes fewer of the images. At least that is what appears to be happening. The performance when zoomed way in is pretty good, so my next step was to create a single, lower resolution image of the 9. My plan was to use this image at greater viewing extents, and switch to the 9 greater detail images as the user zooms in. After a bit of experimenting, I ended up with a 60mb image (a composite of the nine) for zoomed out viewing and the nine origionals for zoomed in viewing, making a total of ten layers in my map file necesary. I was pretty happy with the result, so I didn't go on to try any other methods. However, my example only references a single township. If I were working with an entire county (or a state) of 30mb images, I might vary my approach.

This gives good performance (only needed files are touched, with lots of overviews (pyramids) you don't have to read much data from each file), and you don't have to massage you data too much. If you have alot of files, I would also encourage you to build at least one full region overview file to avoid having to touch every file to show a region wide map.

This is the minx, miny, maxx, maxy extent of the map, typically a rectangle within which your entire map is comfortably contained. The units are in map units... what units that the shapefiles were produced in... lat long, decimal degrees, feet, state plane, etc. Again, the easiest way I know to find the extent of a shapefile is to open it in ArcView, draw a rectangle so it completely contains your map, select the rectangle and right-click with your mouse... choose properties and you will see the coords for the rect.

Nope, the extent defines the area of display and it depends on what coords is your shape (geografic coords, UTM, etc.) the demo comes with a perl script called showextent.pl that shows you the extent of a shape. -- V.

In-Reply-To: <13858AA1A74F30419F319ACB66A9D122CF6A@mercator.topozone.com> Message-ID: Thanks for everyone's emails. I sent a few responses, but here's basically the project in case people are interested. One thought was to provide a "how-to" as a result of the dev work on this project so others can use similar tools to build theirs. Although outsourcing is a good option for my basic needs, I need to work on firmly integrating a mapserver with the functionality of the web site. I don't need the exactness of Topozone since I can link to you folks to get "real" maps ;) It'd be nice of course, but basic features are only really needed so people can get a general idea of where things are in relation to caches and other waypoints. --------------- Geocaching.com is looking for assistance in integrating Mapserver with the web site, currently running with IIS and ASP on Windows2k with a SQL2k database. We currently have a COM object called AspMap, which works quite well, but I'm afraid will not be able to handle the traffic. This month we'll have 2mil pageviews, and I expect with maps we'll get considerably more traffic from people clicking to zoom, pan, etc once the maps are in place. Here's a simple map of the world using two shapefiles - one with geocaches in the last 7 days (yellow)and one of the other active caches (white). We're at 4500 points and increasing by 350 caches a week (this number is growing) http://www.geocaching.com/map Here's one specific to Washington State. Zooming in gives you more features (but still sparse). Green ones listed are the new caches shapefile (last 7 days) and the rest in blue with the orange lid. If you had an account it would also show the ones you visited as checked off (another layer generated on-the-fly) http://www.geocaching.com/map/wa.asp I'm looking for assistance to do the following - 1. Set up Mapserver in an NT environment (of course!). We do have linux boxes but since the site runs in ASP and some functions will involve session cookies it made more sense to stick with the platform. 2. Generate worldwide maps of cache locations, and allow zooming to street level for US (and hopefully the rest of the world where maps are available). 2a. I will need to acquire these maps/shapefiles as well. Any idea of cost estimates for this data would be helpful. 3. Allow integration of data from the SQL2k database, including vector files (such as track logs from a GPS unit), and caches. Also other items such as interesting locations, etc as different icons. I can handle all the database development, but need assistance integrating with ASP (or another option). 4. Be able to map URLs to the image to allow clicking on points and having the site relocate you to the new URL. Thanks folks!

SCSI is definately better, but if the SCSI price tag is simply too much you can get add on IDE RAID cards which will off-load most of the work from the CPU. Some new motherboards also come with embedded IDE-RAID controllers. Note that Software RAID is slower than Hardware RAID, make sure you know which one is being offered. Not all IDE cards are created equal: search the newsgroups for problems on the particular model(s) you are interested in. Also check the combinations, sometimes an otherwise reliable card just won't work well with a particular motherboard or chipset. Promise seems to be one of the most reliable brands (or at least one with best mindshare). For an article which tells you way more than you ever wanted to know see (page 6 of 30) http://www.anandtech.com/storage/showdoc.html?i=1491&p=6 If you aren't a hardware nut there are companies who sell boxed IDE RAID solutions. Search Keywords: IDE|SCSI RAID, JBOD (Just a Bunch Of Disks), SAN (Storage Area Network), NAS (Network Attached Storage). Bottom line: if the server is likely to be around for awhile and you haven't purchased it (or all the drives) yet, go with scsi and take the time to plan/research everything out. If you already have a server in production with IDE drives, try a cheap test: buy a two drive IDE drive controller (ATA66 or better) and see what happens. The card shouldn't set you back more than $100US. cheers, -matt ----------------------------------------------------------------- Matt Wilkie * Yukon Renewable Resources GIS http://renres.gov.yk.ca/pubs/rrgis/ ----------------------------------------------------------------- From shawatw at Princeton.EDU Mon Jul 30 13:02:06 2001 From: shawatw at Princeton.EDU (Tsering Wangyal Shawa) Date: Mon, 30 Jul 2001 16:02:06 -0400 Subject: [mapserver-users] Mime-Version: 1.0 Message-ID: <3.0.32.20010730160206.01560cb0@imap.princeton.edu> Please unsubscribe me From ed at topozone.com Mon Jul 30 13:09:43 2001 From: ed at topozone.com (Ed McNierney) Date: Mon, 30 Jul 2001 16:09:43 -0400 Subject: [mapserver-users] Image Speed Questions---Generic Message-ID: <13858AA1A74F30419F319ACB66A9D12201913F@mercator.topozone.com> Lowell - Since November, 1999, the TopoZone has been in the business of serving "high-res imagery" "for a large spatial extent" by providing USGS DRG (topographic) maps of the entire US online. We're now migrating that application to a MapServer platform so we can add some interesting stuff to it. I've been in and out of the PC graphics biz for about 20 years now, and I've learned a bit about performance. I wanted to take the time to write a thorough commentary on raster tips, but that's going to take me a while. Here's a shorter version along with a promise for a more extensive treatment someday as soon as I can. For computer graphics in general I like to live by two golden rules - (1) precompute the hell out of everything, and (2) trivially reject as much as you can as fast as you can. Here are some notes on both rules. 1. Precompute everything - if you're trying to serve a lot of users on the Web with relatively inexpensive hardware, you'll find that a fast RAID-5 SCSI array is much cheaper than lots of RAM and CPU. Wherever it's possible, think hard about how you can precompute raster results rather than doing them on the fly. Look at a simple case - zooming out from a raster image that's viewed at 100% (1:1) zoom. When you zoom out 4x, you're reading 16 times more input pixels than you are writing output pixels. At 16x it's 256 times more; you're basically reading a lot of data and throwing 99.5% of it away. For the TopoZone site we chose to offer four fixed zoom levels - period. They are all precomputed and there is no on-the-fly scaling. This is a more reasonable approach for topo maps, because they're useful (i.e. readable) only at a relatively small range of scales. For aerial or satellite imagery, or other continuous-tone imagery, you can zoom out farther and still have things work. Using GDAL support with overviews (built with GDALADDO) is a very easy way to do this. Precomputing zoom scales offers a tradeoff between disk space and speed - the more space you use, the faster things will go. However, the highest-level overviews require the smallest amount of space but actually save the most time. If you created only one 4x overview, it would (roughly) increase your storage space by only about 7% (since the 4x view is 1/16th the size of the original) but for all views zoomed out beyond 4x you're going to deal with 1/16th as many pixels. Creating lots of overviews (2, 4, 8, 16, 32, etc.) gives you the best performance, but think very hard about whether you really need that 2x overview. Your mileage may vary based on usage, CPU speed, RAM, disk performance, etc. so you really should test things yourself in your real environment. 2. Trivially reject as much as you can - "trivial rejection" is the process of very quickly deciding which input data is not needed in the output map, and ignoring it as quickly as possible. For raster data sets, the way to do this is with a TILEINDEX shapefile. By reading ONE input fileset (the TILEINDEX shapefile), you can very quickly determine exactly which TIFF input files are needed to create the requested map. This is enormously faster than reading lots of TIFF/GeoTIFF files, extracting the bounding box from each, and then discovering that you never needed to open most of them in the first place. Disk seek time is expensive compared to sequential reading, so reading 100,000 bytes from one file is much, much faster than reading 100 bytes from each of 1,000 files. In addition to these general rules, make sure your images don't make life difficult for MapServer. For TIFF images, this particularly means making sure they are created with only one (or a few) rows per strip. Some image libraries create single-strip TIFF files, with all the rows in one strip. If you are using any sort of data compression (PackBits, for example) MapServer will need to read and interpret (i.e. decompress) all the data in that strip up to the point you need. For example, if you've got a 7,000-row file in one strip, and you need to display the bottom few rows of that file, MapServer will need to read from disk AND decompress essentially the entire file just to get a few lines from it. If you have one row per strip, you will get less effective compression (because each row is compressed independently) but you will only need to read the rows you need. A compromise with a small number of rows per strip might give you better compression with acceptable performance. Finally, know your data and your users. Some data types compress better than others. Some are virtually incompressible (at least within the world of formats TIFF supports). Some data types are used differently than others - as I suggested above, a 32x zoom out on a 1-meter aerial photo is a somewhat reasonable thing to ask for, while the same zoom on a topographic map produces illegible mush. I'm still shuffling around some R&D equipment, but sometime this week I'll post a link to a MapServer site that offers a 30-meter shaded relief map of the entire US and 2.5-meter topographic maps of the entire US. Together they're over 60,000 files with about 300 GB of data, and they illustrate some of the things I've talked about here. - Ed Ed McNierney Chief Mapmaker TopoZone.com ed at topozone.com (978) 251-4242 -----Original Message----- From: Ballard,Lowell [mailto:LBallard at YesVirginia.org] Sent: Thursday, July 26, 2001 1:15 PM To: 'mapserver-users at lists.gis.umn.edu' Subject: [mapserver-users] Image Speed Questions---Generic Say, for example, you needed to display/serve high-res imagery (on the Internet) for a large spatial extent (e.g., a state or region). There would be several ways to get this done. For example: 1. You could use multiple images and reference each as an individual layer (administrative nightmare). 2. You could use multiple images and get at them through an image catalog. 3. You could mosaic them into one large image (could get REALLY big fast--probably not feasible) 4. If pyramid layers/aux/MrSid were supported you use them to display moderate sized mosaics or original imagery (greatly reduce storage footprint but uncomressing hammers CPU cycles). 5. You could resample imagery at different resolutions (1m pixel resolution; 5m; 10m) and reference each collection (e.g., 5m) with a different image catalog depending on viewing scale (i.e., viewing at county-extent use 10m catalog; city-level use 5m; subdivision use 1m). 6. You store them all in SDE (~2:1 compression lossless). 7. About any combination of the above (e.g., resample imagery to 1m, 5m etc and create pyramids for those). 8. ....... I'm curious how others would accomplish/approach this task. I can post a summary.

By default MapServer pages ARE cached by the browser, unless you added some custom headers to change that behavior, which is a fairly standard trick.

Message-ID: <13858AA1A74F30419F319ACB66A9D122019145@mercator.topozone.com> No, on NT your data does NOT have to be on a local drive. This is probably a permissions problem. But you need to know a bit more about IIS and NT security. By default (you can change it), NT creates a unique user account called IUSR_ for IIS. If your machine is named FOO, then the account is named IUSR_FOO. This is NOT a domain-level account - it's a local machine account. This gives you fine control over exactly what files this account has access to, and it minimizes the risk that you'll give a Web user access to something you shouldn't. If you're using anonymous Web access, all Web server activities run under the security context of the IUSR_FOO account. In other words, the person sitting at the Web browser is acting like they have logged in as the user IUSR_FOO. The first thing you'll need to do is to make sure IUSR_FOO has appropriate access to all the directories it will need. This generally comes down to Read permission on the template and map files, Read and Execute on the CGI directory, and Read and Write permission on the directory where MapServer creates output files. However, the restrictions on the IUSR_FOO account prevent it from getting access to domain resources. That's what local accounts are supposed to do. If you want your Web server to have access to domain resources (that is, shared files on other machines in the domain) you will need to change IIS to use a domain-level account rather than a local machine account. This is easy to do - under Internet Services Manager, right-click on the Web site and select Properties. On the Directory Security page, hit the Edit... button to edit anonymous access control, the hit the next Edit... button to change the account IIS uses for that Web site. Each site can have its own account if you need that. Be sure to create this account first, and remember that it needs to be a domain-level account. Now you will have IIS running in a domain-level security context. You can grant it permission to do anything to any file anywhere on your domain. This can be very helpful, but it can be very dangerous, too. Make sure you keep that new IIS account on a short leash - don't make it a member of any groups, and remember that anything that's accessible to all users on your domain will be accessible to the Web user. This is a vulnerability that's very unlikely to be exploited by a person, but puts you at risk of being attacked by viruses/worms/etc. It's not a bad thing - I do it on my systems - but you have to be careful. You should get your network administrator, or at least a consultant who knows something about NT security, to review your configuration and make recommendations before you expose it to the wide world. - Ed Ed McNierney Chief Mapmaker TopoZone.com ed at topozone.com (978) 251-4242 -----Original Message----- From: Hankley, Chip [mailto:Chip.Hankley at GASAI.Com] Sent: Tuesday, July 31, 2001 1:54 PM To: 'Richard Greenwood'; mapserver-users at lists.gis.umn.edu Subject: RE: [mapserver-users] msDrawRaster TileIndex TileItem Location HELP!

So to answer your question, no there was no GIF support when using GD 1.8 but if you comiled MapServer with older versions of GD (1.2, 1.3 at least) then you could still use GIF (see http://www2.dmsolutions.ca/mapserver/php_mapscript/php_mapscript_docs.html): ------ With GD 1.2, 1.3, 1.6: int saveImage(string filename, int transparent, int interlace) With GD 1.8 (only if JPEG enabled in GD 1.8): int saveImage(string filename, int type, int transparent, int interlace, int quality) ------ In MapServer 3.5, there is only one version of the saveImage() call which supports all the formats that your GD lib supports (see http://www2.dmsolutions.ca/mapserver/php_mapscript/php_mapscript_docs35.html): ------ int saveImage(string filename, int type, int transparent, int interlace, int quality) Writes image object to specifed filename. Passing an empty filename sends output to stdout. In this case, the PHP header() function should be used to set the documents's content-type prior to calling saveImage(). Type can be either MS_GIF, MS_PNG, MS_JPEG or MS_WBMP (depends on which version of GD was used to compile MapScript) Quality should be a value in the range 0-95, higher value implies higher image quality and larger image sizes. If quality is negative, then the default IJG JPEG quality value is used (the quality value is ignored for all formats other than JPEG). The function returns -1 on error. On success, it returns either 0 if writing to an external file, or the number of bytes written if output is sent to stdout. ------ Note that you can also get a patched GD1.8.4 that supports GIF and will work with MapServer 3.5 ... as long as you're aware of the Unisys patent issues of course! ;) -- ------------------------------------------------------------ Daniel Morissette morissette at dmsolutions.ca DM Solutions Group http://www.dmsolutions.ca/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

Copying all the data to the c: drive (where Mapserver is installed) made good. IIS/PWS use an account called IUSR_. So, if you computer is called mapper, an account called IUSR_mapper is automatically created, and a random password is generated for it. This insures that anyone hitting the webserver is able to view the website. IIS service itself logs on as a local system account.

I went around the issue a few times trying to get the cgi to work, yet restrict access to the map file (because that file contains drive and data path information, which could help compromise a server...). The user accessing the content, if coming from the internet, should be IUSR_* (the * could be a computer name or something else). This user is considered anonymous and has not authenticated in any way. Check your IIS directory security properties and see how your users are authenticating - you could be allowing a range of users to log on, from anonymous to domain authenticated. The domain of this user will most likely not be the domain(s) in which the machine is a member, but the machine name itself. In other words, IUSR_* is not a member of any domain. This is how our Win2000 server works. So if you want an internet user to have access to a file, you must explicitly grant IUSR_* access to the file, but that could be complicated if the file is on another machine in the domain. That machine may require _authorized_ (and authentic) users to be members of the domain, and that would not be a good idea for the anonymous internet account. Of course, this all depends on what user is accessing the file. Perhaps the anonymous user is not actually accessing the data files - the server software is. If the server software is accessing a file as admin (or similar), can it access the domain? I doubt it, because it is running under a local account, not a domain account.

Message-ID: <13858AA1A74F30419F319ACB66A9D122019146@mercator.topozone.com> Sam et al. - I think I covered a lot of this with my previous post, but there seems to be enough interest to warrant some clarification. I've worked with both Windows and UNIX networks for a long time, and I don't find either particularly hard to manage or easy to manage, but they're certainly different. It's really worth spending some time understanding the philosophy behind Windows networking before you expose your network assets to the world. One of the fundamental precepts of Windows NT/2000 security is that EVERY access to every resource on every system is done through a security context. For most purposes, it's simple enough to think of this as a user context or user login. For every operation there is always the notion of an authenticated user context. In particular, the comment "This user is considered anonymous and has not authenticated in any way" is correct from a Web site security point of view (no dialog box popped up when someone tried to access your Web page) but it is completely incorrect from a Windows networking point of view. When a Web site developer tells IIS to permit anonymous access to a Web site, or to a page on a site, Windows basically says "OK, since all those Web users look the same to me, and they haven't logged in anywhere, YOU give me a valid user account and password for them to use." This is the role served, by default, by the IUSR_ account. You can change that to any account you like, but obviously all Web visitors use the same account because there's no way to tell them apart. Although (as someone mentioned) the Web server itself (IIS) is running under the local SYSTEM account, it impersonates the IUSR_ account for all access to files and other resources. This includes every single file, even if your Web server is doing nothing but serving one, simple HTML file. The IUSR_ account must have Read access to that file. Windows networking supports local machine accounts and domain accounts. Local machine accounts can ONLY have access to resources on their local machine. Domain accounts can use resources on any machine on the network, provided they are granted access rights to those resources. You CAN'T sit down at machine FOO and set the permissions on a file to give BAR\IUSR_BAR Read access to that file. (BAR\IUSR_BAR means the local account IUSR_BAR on the MACHINE named BAR.) If FOO and BAR are members of a domain named BAZ, then you can grant access (on FOO) to any domain account (BAZ\Guest or BAZ\Administrator or anything). If you want IIS to grant an anonymous Web visitor rights to read any file that's not on the local IIS machine, you MUST change IIS' default (and conservative) setting and assign a domain user account for it to use. You can then set the access rights on any file or other resource to grant that domain user account access. That machine must have access to a domain controller so the IIS login account can be authenticated when the first anonymous access occurs. Always create an account that is used only for this purpose; don't share another account. Always realize that this account can potentially have access to any resource on your network, so be careful. - Ed Ed McNierney Chief Mapmaker TopoZone.com -----Original Message----- From: Sam Paske [mailto:spaske at kapur-assoc.com] Sent: Tuesday, July 31, 2001 5:32 PM To: Hankley, Chip Cc: mapserver-users at lists.gis.umn.edu Subject: RE: [mapserver-users] msDrawRaster TileIndex TileItem Location HELP!

Thanks for the explanation. I have to find a work-around though... my problem is selecting records from a MySQL table, and using the primary key (parcel_id, or tax_id, or whatever_id) to find the associated record in the .dbf, get its row number, lookup the shape to get its extent, etc. I have decided to load a copy of the dbf into a MySQL table and thereby completely bypassing the dbf altogether. Works much better except for the minor issue of keeping the dbf and its MySQL copy synced. Maybe having an Xbase query method in Mapscript (SDL talked of something like this in v. 3.5) would alleviate such contortions. > >> -- >> >> a house-keeping question -- >> >> I find that the messages I post to the mapserver list take several >> hours to >> appear in my email... 5-8 hours delay.

As I recall, there are approx. 400 subscribers to the list... that should not be a _large_ load. In any case, I would be happy to receive mail digest format if that is the only way to get the postings quicker. I do get 7-10 hour delays. So, usually I find it better to cc the email to the original poster as well (like this one to you). However, if in a bind to get an answer quickly, the delay still stinks. > > >> Is it possible to migrate to a web-based forums so we can access the >> forums >> (and not just the archives) from anywhere?

(Of course, that's just my opinion :) You are absolutely right... but, indeed, there are forums that include the email option... I have been developing on Cold Fusion now for half a decade, and find the CF support forums invaluable (forums.allaire.com). I post on the forum, of course, it is instantaneous. And, I have an option of subscribing to that thread. So, all future postings to that thread (or to any/all subscribed threads) get emailed to me. In the email is embedded a link to the actual post on the web as well. This way I have the best of both worlds... immediate posting and response (usually all queries get answered within the hour), and I don't even have to go to the web site if I don't want to or can't... emails come to me. Right now there is the issue of the delay, of course. In addition, the search interface is really cruddy... surely, a threaded interface is more attractive and intuitive. Again, something to think about. pk/ From Rich at GreenwoodMap.com Tue Jul 31 20:07:12 2001 From: Rich at GreenwoodMap.com (Richard Greenwood) Date: Tue, 31 Jul 2001 21:07:12 -0600 Subject: [mapserver-users] Image Speed Questions---Generic Message-ID: <5.1.0.14.0.20010731210250.040858c0@mail.GreenwoodMap.com> Hello List, Ed McNierney sent this reply to me in which he explains strips and rows in TIFF files. I found his explanation useful and informative. Since I did not see it come thru the list, I thought I'd forward it. Rich >Each TIFF file is made up of one or more strips, each of which contains >one or more rows. Files with lots of rows per strip are smaller (under >any compression method) while files with few rows per strip are faster. >That's because the strip needs to be read from its beginning in order to >find any row inside it. This is pretty insignificant for uncompressed >TIFFs, because the location of any row start inside a strip can be >readily calculated, and the file read pointer moved right there. > >For compressed TIFFs (packbits, lzw, or other) this is more of a >problem. Each strip is compressed as a single block of data, and >(especially with LZW) you can't just jump to the start of data in the >middle of a compressed block.
