[mapserver-users] How best to serve very large (300GB) raster data?
I've been using ESRI products for quite a while. To serve a very large raster dataset I have (about 300 GB), or really any raster or vector, I usually just load the data into ArcSDE installed on Oracle and server through ArcIMS. However, I want to move away from ESRI/Oracle and into a more open environment, with all components being open source if possible. How best to serve a large raster dataset of about 300 GB? My data is in 2010 tiles, each a 3-band TIF of about 135 MB. From my initial research, I like what MapServer can do and all of the potential clients (OpenLayers, ka-Map, and many more.) I also really like PostGIS for vectors...and have already started a project with PostGIS points, being maintained by Quantum GIS and mapped through Google Maps Javascript API and some AJAX/PHP code I wrote. My biggest worry is dealing with the very large rasters. Ideally, a tile server would be nice but I don't want to create the tiles through an ESRI product (like Arc2Earth or HTMLImageMapper.) I really like the possibility of TileCache (http://www.tilecache.org/) working with MapServer. The immediate question is what would be the raster data source to MapServer? Should I create tiles inside each TIF using gdal_translate and then a shapefile tileindex? Maybe go with compressed JPGs instead of TIFs since they usually have much smaller file sizes? I'm not sure where to start. Thanks for any guidance you can offer. - John **** John Callahan Geospatial Application Developer Delaware Geological Survey University of Delaware 227 Academy St, Newark DE 19716-7501 Tel: (302) 831-2833 Email: [EMAIL PROTECTED] http://www.dgs.udel.edu ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [MAPSERVER-USERS] MapFile2XML conversion
Is it possible to allow MapServer to use KML, or a variation thereof? I really don't what would be entailed. For example, KML can store coordinates for displaying vectors, which would be pointless in our context. Can KML point to shapefiles or tables for vectors like it can point to TIFs for rasters? If so, it seems like the infrastructure (styling, external editing packages, viewers, conversion tools, wide adoption) is already there to build on. Can we pull pieces from KML to make it easier for people to adopt without learning a new structure? +1 on keeping the configuration maps as file based. Databases are great for many reasons but add an entirely new level of complexity (and points of failure) for any application. - John John Callahan Geospatial Application Developer Delaware Geological Survey University of Delaware 227 Academy St, Newark DE 19716-7501 Tel: (302) 831-3584 Email: [EMAIL PROTECTED] http://www.dgs.udel.edu Barend Kobben wrote: Hi Bob, YES, by all means do move to XML.

A preferable approach would be something that could be stored in a DB in some fashion for querying/assembly processes. It seems on the surface like a DB schema could be developed to handle the MapFile storage aspects. A first step would be in how to best approach moving into an XML way of life for the MapFiles. Would it make any sense in the beginning to just build a MapFile2XML convertor (I would imagine this would be needed before anyone would sign up for XML) and once something like this is a state close to production, the innards of MapServer would then be made to parse the XML directly? Another approach might be to do something like MapFile2SQL first, and then the MapFile2XML. This might save some time and seem like it would make standardization easier, since it would need to be inside of the DB fist. Has anyone tried putting together any requirements list along these lines at all? Is it going to be something where we just need to jump in and build something even if it might be a wrong approach to begin with?

Re: [MAPSERVER-USERS] MapFile2XML conversion
I know what you mean about different applications of XML. However, can a single file or format serve both needs? KML is an output format and used in many programs but it can be viewed as a map description format as well: it can point to multiple datasets, access dynamic web services and WMS, adds style information, screen overlays, and more. Aside from inclusion of coordinates/geometry of vectors data instead of referencing a vector dataset, KML seems to do accomplish similar tasks as map files. I've always thought KML becomes difficult to share when locally referencing large rasters; KML as input to a map server engine would solve that. It would be huge stretch to make something like this work but the lure of incorporating the successes of KML into an open source project (as something more than just an output format) just got me wondering. Even converting KML files to map files (placemarks/paths/polygons become shapefiles) may be beneficial. Just some thoughts... - John John Callahan Geospatial Application Developer Delaware Geological Survey University of Delaware 227 Academy St, Newark DE 19716-7501 Tel: (302) 831-3584 Email: [EMAIL PROTECTED] http://www.dgs.udel.edu Bob Basques wrote: John, You're starting to think about two different applications of XML.

Re: [mapserver-users] satellite / aerial imagery
The USGS site is a good one. Check out http://gisdata.usgs.net/ for more info from USGS. Also check out TerraServer and the satellite imagery on http://www.perrygeo.net/wordpress/?p=35 Searching through http://geodata.gov/ may reveal something. I usually get frustrated with that site but you never know what you'll find. Note that very-high resolution imagery for North America as a raster/geotif may be a bit large. Connecting to a WMS service or Tile Map Server (like Google, Yahoo, VE) might be a better bet. I'm just getting started with MapServer so I really couldn't provide any instruction though. - John **** John Callahan Geospatial Application Developer Delaware Geological Survey University of Delaware 227 Academy St, Newark DE 19716-7501 Tel: (302) 831-3584 Email: [EMAIL PROTECTED] http://www.dgs.udel.edu Ray Collett wrote: http://seamless.usgs.gov/ On Sat, Jun 28, 2008 at 12:39 PM, Mark Brooks <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>> wrote: I am working on a mapserver project and need satellite or aerial imagery, preferably at a very high resolution.

Re: [mapserver-users] optimize raster for mapserver - gdal geoTIFF source
1) I use average as well. No problems or complaints so far.
2) I use uncompressed TIFs when I can and not worry about file sizes unless
necessary. If compression is necessary, I use LZW first, then JPEG (75 -
90) if more compression is needed. They all work fine.
3) Also have never heard of those processing directives.

Re: [mapserver-users] map file paths
Basically what I do is copy and rename mapserv.exe to some name I want in the URL. Then, if a request goes to that file, set the MS_MAPFILE variable to the relevant map file. This has worked well for me so far. For example, my organization recently published our 15th geologic map of out state. I want people to refer to it as geomap15. Therefore, I copied and renamed mapserv.exe to geomap15 (no exe extension, file still in cgi-bin directory). Then, I have the following in my httpd.conf file: SetEnvIf Request_URI "/cgi-bin/geomap15" MS_MAPFILE=C:/pathtomapfile/geomap15.map My URLs then look something like: http://maps.dgs.udel.edu/cgi-bin/geomap15?

Re: [mapserver-users] map file paths
The PHP mapscript wrapper looks promising. Thanks. The examples would need to be combined into one php file to handle both GetMap and GetCapabilities requests. Seems doable. I'm not a programmer and didn't want to get into mapscript, however, modifying this script template doesn't seem too difficult (if you already have PHP, which my server does.) I'm not a big fan of copying and renaming the mapserv.exe file but it does work well. We only publish a handful of services and do not expect to significantly increase in the future. If we do, scripting a batch file would work just as well. This is relatively easy and without the need to install (re: maintenance, security) or learn additional programming languages. For me, it's also important to have short, easily readable URLs to send out to people that use our WMS services. I do not want the extra "?map=mymap" parameters at the end of the URLs. For one reason or another, things always get screwed up when people start pasting these URLs into their desktop GIS or other apps. Simpler the better, even if it's not elegant or involves slightly more work on my part. - John ****** John Callahan, Research Scientist Delaware Geological Survey, University of Delaware URL: http://www.dgs.udel.edu ** On Thu, Nov 4, 2010 at 2:53 AM, Waberzeck, Thomas < thomas.waberz...@liag-hannover.de> wrote: > Jukka Rahkonen wrote: > > P Kishor wrote: > > > > > So you have 15 copies of the binary floating around on your computer. > > > What a nightmare.

[mapserver-users] job opportunity for web project

I am not sure which method/software to use for these tasks.] I'm looking to hire someone to help on a web project I'm working on. We use Postgres/PostGIS as the database, MapServer as the map engine, and OpenLayers/GeoExt as the javascript mapping framework on the front end. Server-side: PHP/Python, Windows, Apache. The project involves displaying numerous spatial data layers on a map with common functionality; this part has already been done, (screenshot at http://www.dgs.udel.edu/temp/screenshot_weblayout.png)However, we need to add several specific tasks, such as: - display subsets of points based on a certain criteria selected by user via radio-buttons - based on mouse click, return values of the polygon or raster grid cell clicked within - use attribute of a clicked polygon to perform queries/reporting from other tables - if a groundwater well is click on (points), then display time series graph of data - based on user selected criteria, select points and return as line and display on map If you would be interested in this opportunity or think this post would be more appropriate on another list, please let me know. It's fine with me if any work done is shared back to the community. Start date is anytime, sooner the better.

[mapserver-users] elevation DEM color ramp map file
I'm just curious but does anyone know of Mapserver .map files, or color map text files, with classes designed for a elevation DEM? Or possibly a list of color ramps that work well for DEM maps? I read that GRASS had some predefined templates for applying color to DEMs and wondering if Mapserver has a similar thing, perhaps shared on a wiki or other site. The DEM I'm working with now has low relief, from -5 meters to about 150 meters, however a general method or set of map files that can be applied to a range of DEMs could be helpful to many. Does something like this exist?

[mapserver-users] advice on books
Can anyone point me to a good book on learning Mapserver, and possibly OpenLayers as well? I don't usually buy books on software products as there's so much available online. However, I recently purchased PostGIS in Action and it's helped significantly. I wonder if there's a similar quality book out there on Mapserver. Something higher than intro level would be preferable.

Re: [mapserver-users] advice on books
Thanks Daniel. The OpenLayers book looks interesting. Even though I typically do fine with online examples, it's probably worth the purchase, especially since I may be migrating several Google Maps apps to OpenLayers at some point. That Mapserver book is from 2005, I agree a bit too old but the only one I can find as well.

Re: [mapserver-users] recommended tile caching mechanism with `mode=tile`
I'm sure lots of people are very interested in this topic. Very nice. I'm assuming at some point MapServer MapCache will be supported on the Windows platform.

[mapserver-users] gradient display of raster DEM data
I know this has been asked before but I thought I'd ask to see if anything changed. I'm looking to display a raster digital elevation model in mapserver. My data is in flat files, img and tiff. I'd like to display this data as a continuous gradient color range, rather than using CLASS categories/bins for specific colors. Is it still tru ethat this is not possible, easily? One method (passed to me on this list) was too generate the colored image I want in another program, using GMT or similar tool, then use that in mapserver. This seems like the best option but is non-trivial to someone who hasn't done this before. (though not terribly difficult.) I also read about the use of DATARANGE and COLORRANGE in mapserver. However, these are not in the documentation. Are these available in trunk only? A ticket was generated that seems to say this will be included with MS 6.2. (http://trac.osgeo.org/mapserver/ticket/1305) Any insight on whether this is still the plan?

Re: [mapserver-users] gradient display of raster DEM data
Thanks again for the idea of using multiple classes but I can't seem to get it to work. Has anyone else had success with this method? It seems as though it's applying only the first defined COLORRANGE to full range of the values in the dataset. I've tried using the below syntax (only COLORRANGE and DATARANGE in each CLASS) as well as the (proposed?) block syntax as defined at http://mapserver.org/development/rfc/ms-rfc-6.html (which gives me errors for RANGEITEM and invalid hex color for MINCOLOR.)

[mapserver-users] mapcache
I'm giving mapcache a try but with no luck. Well, some luck. The module loads fine and the demo (vmap0, http://127.0.0.1/mapcache/demo/wms) also works fine. I see the tiles being generated on disk. Great. However, the problem comes in with my own data/services. A few questions may help me determine the problem. - in the source element, how do you define multiple layers? Comma separated or separate entries? - in the tileset element, can you have multiple grid entries? It doesn't seem like it from reading the documentation but the sample tileset shows both the "g" and "WGS84" grids. - for cache type attributes, what are the possible values? The docs show several possibilities (disk, sqllite, memcache) but the sample shows type="tiff" which is not listed on the doc page. Can other file extensions be used here? - when I define a FORMAT with name and type, how does that get used? I see that is called in the tileset but how does that relate to the image type under getmap/params/format? The doc page I am referring to is at http://www.mapserver.org/trunk/mapcache/config.html. I'm sure I'll have other questions as I work my way through.

Re: [mapserver-users] mapcache
Thanks for the help but I think I'm misunderstanding mapcache at a more basic level. What is the mapcachealias? In the apache httpd.conf file (using the latest MS4W), there is MapCacheAlias /mapcache "C:/ms4w/apps/mapcache/mapcache.xml" How does that relate to my own mapservices? What changes do I need to make to have them cached? My mapservices typically look like http://servername/myservice?LAYERS=layer1,layer2,...&REQUEST=GetMap&SERVICE=WMS&;.. .. Something else that seems strange is when looking at the demo ( http://servername/mapcache/dem/wms), it makes available additional layers based on entries in the current mapcache.xml file. When I try to select my own service through the demo interface, I see that it makes a GetMap request with LAYERS = tileset name. Does the name I define for the tileset in mapcache.xml have to be specific to my map service? or any special requirements?

[mapserver-users] polygon symbol image fill problem
I hope this is an easy question. I'm drawing a polygon dataset through WMS. For some of the classes, I am filling those polygons with a local PNG file. However, the image itself has an outline. (see attached image for an example) Is there a way to remove the symbol image outline inside my polygon features? Here is a snippet of my map file. I'm using Mapserver 6.0.2 on Windows (I don't seem to remember this happening in older versions of Mapserver but maybe I missed it.) Thanks.

Re: [mapserver-users] polygon symbol image fill problem
@Matt: I doubt I can use the standard symbol features of Mapserver. Maybe. The hatch symbol is but one example. I have approx 10 - 20 image-based fills of all different types. These were created for our published, standardized geologic maps. Our web-based maps need to look identical to our publications. Thanks for the suggestion. @Havard: Thanks for the info. I'm glad there's a fix for this in 6.2.

Thank you Eric for the response and references. Yes, working with OneGeology is one of the reasons why GeoSCiML through Mapserver would be useful to us. Their cookbooks do provide some good information.

[mapserver-users] mapserver or MS4W package on Windows x64

At the start, I'll be using Mapserver for viewing of basic WMS services, nothing fancy. Not too far in the future though, I'll be using PHP or Python mapscript code, and/or implementing a package like GeoMoose. My data will be shapefiles, PostGIs features, and a few raster formats.

Re: [mapserver-users] mapserver or MS4W package on Windows x64
I started working with the x64 binaries from Tamas' site at http://vbkto.dyndns.org:1280/sdk/Default.aspx. MSVC2005 (Win64) seemed most appropriate for me. However, I did not see php mapscript support. Is that true? I did see mapscript for java, python, and csharp. Can php mapscript run at all with x64 versions of Apache/PHP and/or Mapserver? If not, then I'll have to give up x64 or PHP. Bummer. I've also been reading that I should run Mapserver in fastcgi mode, in either Win32 or Win64 versions. Does that mean to use PHP mapscript that I need to run PHP in cgi/fastcgi mode and NOT as an apache module? Thanks for any advice.

[mapserver-users] GetCapabilities response being truncated
This seems to be a strange problem... I can generate maps fine through the browser and mode=map. However, responses to GetCapabilities requests are being truncated. They are being truncated to 4053 characters. I've tried this using two separate map files, using different data, both WMS 1.1.0 and 1.1.1 versions, and the same result every time. I found some references to old posts but they didn't seem to apply here. My data in each map file is just one shapefile. My map file symbology is also very simple; it's listed below.

Re: [mapserver-users] GetCapabilities response being truncated
Update: I should rephrase my statements... When run from the command line, c:\apache2.2\cgi-bin\mapserv "QUERY_STRING=map=...REQUEST=GetCapabilities" only works when output is to the screen. When directing the output to a file, like c:\apache2.2\cgi-bin\mapserv "QUERY_STRING=map=...REQUEST=GetCapabilities" > geomap.xml, then the output is again truncated. The limit is not 4053 characters but rather 4096 characters. At least the number makes more sense. Using MapServer 5.4.1, x64 in Windows 2008 Server.

Re: [mapserver-users] GetCapabilities response being truncated
I'm still struggling to find the cause of this strange problem. Has anyone successfully run x64 MapServer (from http://vbkto.dyndns.org:1280/sdk/) on Windows? Has anyone ever seen the 4096 character truncating problem before? Thanks for any help you can provide. - John John Callahan wrote: Update: I should rephrase my statements... When run from the command line, c:\apache2.2\cgi-bin\mapserv "QUERY_STRING=map=...REQUEST=GetCapabilities" only works when output is to the screen. When directing the output to a file, like c:\apache2.2\cgi-bin\mapserv "QUERY_STRING=map=...REQUEST=GetCapabilities" > geomap.xml, then the output is again truncated. The limit is not 4053 characters but rather 4096 characters. At least the number makes more sense. Using MapServer 5.4.1, x64 in Windows 2008 Server. More details on the environment is: http://vbkto.dyndns.org:1280/sdk/PackageInfo.aspx?file=release-1400-x64-gdal-1-6-mapserver-5-4.zip - John John Callahan wrote: This seems to be a strange problem... I can generate maps fine through the browser and mode=map. However, responses to GetCapabilities requests are being truncated. They are being truncated to 4053 characters. I've tried this using two separate map files, using different data, both WMS 1.1.0 and 1.1.1 versions, and the same result every time. I found some references to old posts but they didn't seem to apply here. My data in each map file is just one shapefile. My map file symbology is also very simple; it's listed below. When run from the command line (mapserv "QUERY_STRING=map=...REQUEST=GetCapabilities"), it works perfectly. I'm using the x64 stable build from http://vbkto.dyndns.org:1280/sdk/Default.aspx (MSVC2005 Win64) Apache 2.2.10 and PHP 5.2.5 (x64 versions) if that matters. I just don't know what's going on. Sounds like a problem with my server setup. Has anyone experienced this before? Any suggestions on what I can check?

Re: [mapserver-users] mapserver files to subdomain results in '500 Internal Server Error' when mapserv executable accessed through url
I was getting the exact same error when accessing the GetCapabilities output. For me, the output was getting truncated at 4kb, resulting in the "premature end of script headers" message. Even if I ran the script from the command line, the error was still there (if output was to a file, such as > out.xml, but all worked great when directing output to screen.) http://n2.nabble.com/GetCapabilities-response-being-truncated-td3234081.html The error was also there when connecting to WMS services as a tile server, such as via Google Maps API. About half of the tiles would show up and the other half of the requests had the same error. (a single request to the WMS always worked great, it seemed to be the multiple, almost concurrent requests from the GM api that caused the error.) Unfortunately, I could not solve the problem. The error occurred on two of by Windows Server 2008 machines, a third 2008 machine worked great. My Windows XP and Server 2003 machines worked great so I went with Server 2003. (all machines were x64 bit and used Apache 2.2. I am not sure if they all used vhosts/subdomains or not.) Good luck! I gave up and just went with a machine that worked (one of the benefits of virtualization!) - John ****** John Callahan, Geospatial Application Developer Delaware Geological Survey, University of Delaware Email: john.calla...@udel.edu ** Ted Spradley wrote: The Apache error_log shows: error_log shows: [Mon Sep 21 12:40:20 2009] [error] [client 98.200.238.238] Premature end of script headers: mapserv Thanks, Ted S.

[mapserver-users] php mapscript
Does anyone know of a php_mapscript.dll (this is for Windows) that works with MapServer 5.4+ and PHP 5.2? Looking at MS4W 3.0 beta, it looks like it's for MS 5.4.2 and PHP 5.3. Previous version of MS4W is for PHP 5.2 and MS 5.2.4.
