It looks to me like every new MapServer user goes through the following error message when they try to get MapServer running the first time: msLoadSymbolFile(): Unknown identifier. ( ):(0) or msLoadMap(): Unknown identifier. ( ):(5) and most of the time, it's because MapServer is running on Unix and the .MAP or .SYM file contains DOS ^M chars... either because the original file came from Windows, or because a Windows tool was used to extract the archive and then copy the files to Unix. I'm not a flex/bison expert, so I don't know if it's easy to fix... Anyone has ideas? -- ------------------------------------------------------------ Daniel Morissette danmo at videotron.ca http://pages.infinit.net/danmo/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

Date: Wed, 05 Jul 2000 12:59:36 -0600 Subject: DOS CR/LF in .MAP and .SYM files References: <396377A4.A9FC5AEE@videotron.ca> Message-ID: <39638598.43B0DAE1@gaiaenv.com> Hi Daniel and others, This is a common one (we were nailed by it too when we first began). I like your idea to modify the parser, but I cannot offer much help. Here are some alternate pointers for those interested: * use a decent ftp programme that strips/adds CR to LF (most popular programmes do this for you) * don't forget...if you zip the files before transferring, your ftp prog. will *not* alter the newline characters * if you are running SAMBA, remember that text files are *not* modified by default * use a text editor like UltraEdit (or equivalent) and convert your files once they are on your SAMBA drive or write your files from ArcView with only LF (or vice-versa) * run a script on your files each time they are transferred * in ksh, run SED (e.g., sed "s/$/`echo -e \\\r`/") [convert Unix LF to CR/LF] * in ksh, run SED (e.g., sed 's/.$//') [convert CR/LF to Unix LF...this assumes all lines end in CR/LF] I know this is not what you were looking for, but hopefully it may help some.

Best place to implement would be as an expression function (i.e. TEXT (firstcap([NAME))) or something like that. mapparser.y is the place to start. O'Reilly has a good book on lex and yacc that details how to add functions to a yacc grammar. Of course, this is expensive to do each time you make a map so changing the data would yield the best performance. The arcview method mentioned previously works well as would a simple perl script.

Lemme know... > Steve, We have started working on a similar idea, but that would be written using PHP and MapScript. Our plan is to build a set of simple web interfaces to navigate in the .MAP file, make changes, do previews of maps, and save modified .MAP file. The same way as you, we do not want something based on ArcView or any other GIS... we want it 100% MapServer-based, and we also want something that works on any OS where MapServer can run. However, this is a low priority project for us at the moment, so I'm not sure when we would have something useful available. If you guys get something working before we do and it is in the same style as what we want to build, then we might decide to use your version instead. As usual, I would rather spend our time improving your tool than reinventing the wheel. Please keep us posted. BTW, would it be a good idea to have a page on the MapServer web site with a wish-list, and a list of features planned or currently being added to MapServer? This would give all users an idea of what's coming, and when it might be available. And it would definitely help preventing duplication of efforts. Anyways... just a thought.

This is because one of the possible applications I have for it could be handling hundreds of layers and shape files, and managing a map file for this could get very complicated, especially since there are various people managing the content. I therefore also plan on creating a decent web based admin interface to it (The database, really). It should proove quite nice once it's done, you'll be able to add layers, change colors, add/remove/edit classes, work with labels, etc ... In theory anything mapscript can handle I could manage through the DB Backend and the web interface. It's not exactly what you're working on ... but serves a similar purpose. Like Daniel, I'll probably use PHP to do it, taking advantage of the PHP Module to do things like layer/map previews and so on ... My .02$ !

It is MIT License , see www.gnu.org for definition in early May there was a thread on this subject. Just in short: MapServer is VERY close to the MIT license, but is not identical. Thus you will not find it at www.gnu.org. I consider the difference as neglectable unless you are planning *big business* with the map server. However, Map Server is Free Software!. In that thread in May, there was the proposal to put the license online. It would really help to provide an answer to this FAQ. BTW: I am really impressed by all of your intense work on MapServer.

I had to find a way to simplify the management of all the data. One of the mapping tools we currently use has such a system, which uses a Database backend to store all configuration data, and then provides a web interface to this Database backend, effectively giving users a web interface to the administration of the mapserver. Since MapServer comes with the ever-so-great Perl and PHP wrappers/API's ... Integrating the mapserver with a database becomes almost trivial. So I simply created a database which stores all vareity of objects that can exist within a map file. There are tables for layers, classes, labels, etc ... And each table contains all possible parameters for the said object (So for the layers, there's "data", "maxscale", "maxfeatures", etc ...). Some basic relationship design allows me to relate a label to a class, and a class to a layer. A layer can have several classes of course, and so on ... There's more details, and a few exceptions of course, but that's the jist of it. Currently I'm using this as a backend to an OGC/WMT compliant server (http://www.opengis.org) ... And it is all written in perl. I'll soon be implementing a web/php based admin interface to this RDB ... Right now I just use SQL syntax to add layers, change colors, etc ... Which is still simpler than editing a potentially huge mapfile, and the web interface will give me the flexibility of de-centralized management of the data/content, leaving me to worry about systems/design issues. I'm working right now on potentially getting a page up where all my work would be posted and so on, and I don't think opening up my work under the GPL should not be a problem, gotta ask the bosses first though, although this is my ultimate goal. I'm using PostgreSQL as back end ... It has a lot of features I like that MySQL doesn't, including those nifty geometric datatypes, which I'll probably make use of soon. There, now everybody knows ! :) Comment suggestions and questions are allways welcome !

In other words, it's slow because it's not very powerful and it's generally real busy. In comparison, my private mapserver machine - a 433MHz Alpha system that I use for development and proprietary work - takes only a few seconds to generate a map while the slower machine would take 5 minutes or more. As compared to a map server such as MapQuest (www.mapquest.com), MapServer is far better. MapQuest runs ~$50,000 for the server, and an additional $20,000/year for licensing the map data. It also has many limitations (such as using port 80 to send/received data from the web server - a Very Bad Thing(tm) ) and a limited number of platforms on which it will run. The company I used to work for - I am now self employed as a consultant - purchased MapQuest last year and continues to have problems with it to this day. I paid no money for MapServer and had a couple of operational sites (including my private one) up and running with no problems (other than my own scripting mistakes ;) within a week after I compiled the code. My private site has the entire US and territories (well over 10GB of map data) online with database support for dynamic map content using MapServer and MapScript. All the map data was aquired for free and is current as of 1998.

From: "Stephen Lime" Date: Tue, 16 Nov 1999 15:08:58 -0600 Content-Disposition: inline Got a simple MapScript example running at http://arachnid.dnr.state.mn.us/ms_test. It's a perl script that uses remote data from the USGS (gathered using the perl Net::Finger module) to plot the last 21 semi-major earth quakes around the world. I swiped the world DEM from Doug Nebert's prototype, pretty image. Everything is handled in perl using a few MapScript calls to manipulate map file settings, draw the basemap, map the quake locations and to add a timestamp. It may be slow depending on how busy the USGS servers are cause each pan or zoom executes a finger request. In a production mode you'd probably nab the data every hour or so and work from the copy, still no need to create a shapefile. I'll glady share any details of this script. Yes, documentation is in the works. I hope to have at least some up tonite at the main MapServer site.

Message-ID: <396CBD28.D97D6EBB@gaf.de> Hi there, is there a limitation on the cgi-parameters sent to the mapserver or some other limitation to the number of shapefiles (features). Switching all layers on in my application sometimes causes a server error. This occurs especially with two layers which are displayed depending on the scale and are relative big.

Shapefiles are ArcView's native file format and are usually composed of 3 files with the same basename and extensions .shp, .shx and .dbf. Shapefiles do not contain any topology... e.g. in a shapefile the shared boundaries between 2 polygons are duplicated. Also, ESRI has published the shapefile format specs so several applications (like MapServer) can deal with shapefiles. Coverages are Arc/Info's native format... every coverage comes as a directory in which most of the files have a .adf extension, and the attributes come in an info directory. Coverages can contain topology and thus allow you to do more advanced analysis in Arc/Info. You can open coverages in ArcView but I don't think that you can take advantage of the topology in ArcView (but I could be wrong). I hope that helps! P.S. The coverage specs are not published by ESRI, but have been reverse-engineered... :-) http://pages.infinit.net/danmo/e00/docs/v7_bin_cover.html -- ------------------------------------------------------------ Daniel Morissette danmo at videotron.ca http://pages.infinit.net/danmo/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

Message-ID: It sounds like you would like a static legend for your map. If this is the case, zoom in on your map until the legend looks good. Click on the image that contains the legend. It will have a long name, something like "myapplication2556330.gif". Save it to the directory that contains your application, and give it a more reasonable name. In main template file for your application, instead of referring to your legend like this:
Point directly to the image that you just saved to your server, like this:
If you want to, you can also get fancy and pull the image into Photoshop to clean it up and make it prettier.

No, you query the GIS data not the map. This is true for the standard CGI application. There are workarounds. For example, using MapScript you can post-process the label cache and use it to answer subsequent queries or create a client side image map. Note that an image map is not usable with a form element. This is certainly an area that could use some work. Caching the label cache is probably the best solution. > - I have a point layer with SYMBOLSCALE 200000, MINSIZE 6, MAXSIZE 14 > and I would not that the relate symbol in the legend becomes more or less > big when I zoom in or out.

I tried it with a set of scanned topographic maps (about 500 maps) and it worked fine. What I did was set up an index shapefile of the map tiles. I added a field to this shape file called "LOCATION". In that field, I put the full path to the image tile, such as: "/data/gis/data/drg/files/o37121h8.tif" In my map file, I added this entry: layer name "drg" type raster status on offsite 2 tileindex /data/gis/data/drg/tiles maxscale 24000 end If you have ArcView files showing where the map tiles are, you can modify this and use it for the tile index.

Symbol set paths etc can all be defined relative to the location of your mapfile. So in your mapfile there is really no reason to have full paths. Using your example and assuming the mapfile is: /lotus/domino/data/domino/spaziogisit/mapserver/cartsic/mymap.map then you'd define: LINESET symbols/line.sym MARKERSET symbols/marker.sym and so on... Your mapfile location only really need be specified once, on the initial call to the application, either a url or a start page. In your template files you can use substitutions like: to pass through the mapfile path information. In most of my apps I have to set path values for one file (the mapfile) in one spot and that's it.

I would like to start working to add symbol definitions to the mapfile itself, as well as allowing composite symbols and stipples. I have many clients who wish for their online maps to use the same symbols as their paper maps, and modifying the symbol structure is the only way I can see it happening.

As it's default IIS root is [drive letter]:\inetpub\wwwroot\ that means that anything in here is reached with your browser as http://aptiva /[FILE name] or [DIR Name/FILE name] now the scripts directory is virtual and as far as the web server cares is under the wwwroot. Example: http://aptiva/scripts . In your NT structure it is actually C:\inetpub\scripts\ . It is like UNIX's symbolic paths.

If you don't IE4.1 will try to download the file instead of execute it. There is a predefined cgi_bin in the (InetPub\wwwroot\) dir. This is were you should but the mapserver.exe. Also ensure that that dir is shared to the web server. It will also be a good idea to install the SP6 and OP4 to the server due to numerous bugs in SP4. These are downloads from MS's site. I don't remember the URL, but I will look and send it to you. I have had great success with IIS and the mapserver.

I installed mapserv.exe in c:/cgi-bin and the other files in InetPub\wwwroot\ms_demo.

I also read in the creating applications page about the use of either the GET or the POST cgi request. The online demo uses POST and some other commands. Which should I use?

No longer restricted to paper, maps are now transmitted almost instantly and delivered to the user in a fraction of the time required to distribute maps on paper. They are viewed in a more timely fashion. Weather maps, for example, are updated continuously throughout the day. Most importantly, maps on the Internet are more interactive. They are accessed through a user on a higher-level than is possible with a map on paper. Finally, the Internet is making it possible to more easily distribute different kinds of cartographic displays such as animations. The Internet presents the map user with both a faster method of map distribution and different forms of mapping. The Maps and Internet Commission of the International Cartographic Association provides a global forum for discussion and facilitates the transfer of new cartographic technology and knowledge between researchers in different countries. This commission promotes international cartographic research to address scientific and applied problems related to web-based cartography. The planned sessions at the AAG meeting in NYC are being co-sponsored with the Cartography and Worldwide Web specialty groups. The location of the meetings in New York will encourage attendance from commission members in other parts of the world, particularly Europe. The commission was formed in 1999 at meetings of the International Cartographic Association in Ottawa, Canada. Six initial terms of reference were identified: 1. Focus attention on disseminating maps and spatial data through distributed electronic networks. 2. Examine Internet map usage and project future areas of growth. 3. Examine web map user issues to better serve user needs. Product: Oral or published report. 4. Promote the exchange of information about effective Internet mapping for an international audience. 5. Improve user access to maps by examining the potential of Internet map metadata. 6. Promote instruction on Internet mapping The specialty groups and commission invite papers that address these general areas of research. Rex Cammack from Southwest Missouri State University is organizing these sessions. Rex's DEADLINE for receiving all application materials (including registration form, fee, e-mail, and paper copy of abstract): August 23, 2000.

And you guys deserve it! For display on the maps I would suggest a simple embossed logo. [like a notary stamp] Just the icon from the color version. You could include it in a map without loosing the image's real-estate. A compass (fleur de lis style?) might be an alternative to the globe & serve a dual purpose. The two, color & embossed, need to share a common identity for continuity. --rob ----- Original Message ----- From: "John Hockaday" To: Sent: Monday, July 24, 2000 6:41 PM Subject: Re: Powered by MapServer... > I agree with Steve.

Right now you can't. This is an artifact of the original code that uses an array of layers rather than a linked list. It's on the "todo" list. It is possible to work around it as there is nothing that says that you must draw layers in the order that they appear. The main $map->draw() method assumes this but you can step through the layers in any order you wish and use $layer->draw() to build up the map. For example you could maintain an array of layer names in the order they should be drawn: # load map and add to it (layers, extents, etc...) @layers = {'county', 'water', 'places', 'roads'}; $img = $map->prepareImage(); foreach $name (@layers) { $layer = $map->getLayerByName($name); $layer->draw(...); } $map->drawLabelCache($img); Another possiblity is to store 'dummy' layers as placeholders in the main map file and then edit their definitions instead of starting from scratch. This way the main $map->draw() method will work since the order was set in the map file.

The SQL statement selected on lat/lon and other criteria and returned three fields per row: lat, lon and the text for the label. I was writing the image to a file for server-side caching but mostly because this was running under FastCGI (which means the process was persistent) and I think there was a bug somewhere that was closing STDOUT if I let mapscript write directly to STDOUT.

It has not been ported to PHP4 yet... so the errors you get are (kind of) normal until we have the time to port it to PHP4... hopefully by the end of the summer. Unfortunately, you will have to stick to PHP3 for now. -- ------------------------------------------------------------ Daniel Morissette danmo at videotron.ca http://pages.infinit.net/danmo/ ------------------------------------------------------------ Don't put for tomorrow what you can do today, because if you enjoy it today you can do it again tomorrow.

Message-ID: I'd like to propose a couple of changes to the way symbols are handled. This is to make symbols easier to manage and to support some additional functionality proposed by a couple of other users. The initial change would be this: Do away with separate marker, line and shade symbol files in favor of a single symbol file. Also, allow symbol definitions in the map file. Syntax would be the same and access (i.e. symbols referenced in class objects) would be the same. These changes allow for a simpler MapScript symbol interface and additional opportunities for defining symbols on-the-fly. Begining in 3.3.011 you can already specify a GIF/PNG file (relative to the location of the map file) in a class object (i.e. SYMBOL "graphics/marker.gif") and a symbol is dynamically created. MapScript method $map->getSymbolByName("graphics/marker.gif"); will also work. Any thoughts or can I code it?

References: Message-ID: <397FBA6A.CE2802AA@chesapeake.net> Steve/List, Being one of the advocates for symbol/marker changes, here is some rationale behind the changes. The current symbol files are somewhat static and if the files become large, there is overhead incurred on every invocation of mapserv. Also, the current scheme also does not lend itself to dynamic marker placement very well. (that is, using a marker NOT defined in marker.sym) We want to be able to use external markers from a PATH filespec to make it easier to maintain (no more editing the marker.sym file ;) and (2) make it more programmer friendly and simplifies the mapscript a bit. As far as functionality, it would be nice to interrogate a $class->{symbol} to determine it's height/width and some sort of option to set/get control of collision avoidance (labelcache). (I think needed for both POINT and ANNOTATION layers) And lastly, make sure to preserve the ability to examine to labelcache to extract the polygons of the markers and text placed on the map. I am all for getting rid of marker.sym 100% although it may break my current applications... sometimes change is painful. Anyway to code an interim solutions that works both ways? probably not, but thought I would ask anyway.

Message-ID: <39806E52.63D61C78@gaiaenv.com> One thing that would be a nice feature is to be able to "stack" symbols in a single layer. For example, most of the decent-looking ArcView point symbols are actually two or more .ttf symbols placed directly on top of each other. Another example: dashed thin yellow line on top of thicker black line = highway symbol. For what it's worth, I'm all for moving the symbols into the map file.

Let me know if I'm making this more difficult than it needs to be. Can someone please tell me how mapserver is able to grab name-value pairs in the HTML form with the same name and different values (i.e. name=layer value=snotel, name=layer value=rtg) without overwriting the first value with the second value? If you can tell me which file the code is in, I'll go look it up. I am trying to write a perl script for my map application that will do the same thing. I need to pass name-vals for a set of variables that have a different value for each record in the database. Here's a simplified picture of what I'm doing: name = recordNumber value = 1 name = state value = AZ name = county value = Pima name= recordNumber value = 2 name = state value = WY name = county value = George etc... I want to be able to send these through cgi without having the record 2 values overwrite the record 1 values, and so on. And all I need to do is print them out.

Message-ID: The simple solution pretty much already exists. Loop through the layers, all have to be off to start with, and one-by-one create a legend without any legend text (actually a " "). Do a drawLegend and save. There'd be some slop around the legend but it'd work. You could also create mini maps using a virtual mapfile and one layer for point, line and polygon data. An inline feature could be used to represent the line, center point or the polygon. Just loop over the layers and classes and use those values to set the class values for the appropriate layer in the virtual map, draw and save. You can reference the resulting images at will then in resulting docs. s. >>> 07/27/00 07:24AM >>> I think I know what Jason wants, and I want it myself as well.

Because several types of expressions are supported it wasn't possible to use the standard way of setting values so a helper function was written. The syntax is cl0.setExpression('N'). Basically the value for setExpression *must* conform to the rules for expressions set in the map file docs.

For my first experiments, I got a shapefile from a colleague. It took me some hours of trying around and to find the right numbers for the EXTENT line in the mapfile. Accidentially, I found some numbers that gave me at least a viewable map. But compared with those numbers in the demo-files, they are really strange: EXTENT 22 45.0 -2 57 As said, I found this just by typing more or less random numbers and then using shp2img to get a gif-picture. How can I calculate the EXTENT entries for my maps that they are visible? Many thanks!

The world file is okay, the only coordinates that are specified in the esri type world files are the X and Y of the bottom right corner. They seem to be really close to what you think they should be, so I'd imagine that the world file is not your problem. Mapserver doen't care what projection your data are in, so there isn't any place to specify projections. I'd use arcview or grass or something to make sure they really do line up, and further explore the problem. --Jason John Hockaday wrote: > Hi, > > I am trying to get a jpeg to load as a background image with vector > data on top of it.

THe worldfile X/Y is the upper left pixel, not bottom right. I have found that matching projections is not an exact science. Sometime you need to adjust the X/Y and map units to stretch the raster to get a tight fit. I have done a couple of these.. You have to begin with PROJ and knowing the precise projection and central meridian. That should get it close, then you can tweak the map units in the X/Y to shore up the edges. Also, keep in mind that rasters may never match their vector counterparts, due to basemap mismatch and thinning etc. It very well could be, that your JPG is a different projection??? I have several *very* nice raster maps here (Mountain High Maps) that I am unable to match the base projection with anything in PROJ. Since there is no metadata for the images, it requires much guesswork.
