[mapserver-users] Heatmap / choropleth from points attributes
I am a new mapserver user and have spent countless hours over the last month reading, trying code, etc. before posting here for help. I am trying to generate an image (non-interactive) on a webpage based off of attribute data in a points file. For example, 20 different points equally distributed in a field contain data about the moister level of the soil. I want to make the lowest levels blue and the highest levels yellow, or something like that with some gradients in between. If possible I want it to have interpolated data between them to show the gradual change, but that isn't a must. I also want to wrap it in a polygon that trims the edges. I found some python code that I thought might do the trick , but it seems lots of heat maps are based off of how many points exist in a certain area, and thats now what I am doing. My points contain numbers in the attributes, 5, 25, 92, 71, etc. I feel like I am missing some easy way to do this right in front of me with gdal or something. If someone has any direction or even demo code that would be greatly appreciated. Thanks, Daniel ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] problem with PointFromColumns
I am using a VRT layer to show labels from a csv file. I can get encoding='WKT' to work but encoding='PointFromColumns' does not draw anything. In both cases, I can use ogrinfo -al on the vrt section and it works. When I replace this line- With this line-Mapserver can no longer render it. csv file:"NAME","CLON","CLAT","WKT""Vernon","-5922308","3647303","POINT(-5922308 3647303)""Rapides","-5847278","3659270","POINT(-5847278 3659270)""Grant","-5853735","3710003","POINT(-5853735 3710003)""Avoyelles","-5786275","3645222","POINT(-5786275 3645222)" layer section in mapfile: LAYER CONNECTION " county.csv wkbPoint +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=-40 +x_0=0.0 +y_0=0.0 +k=1.0 +units=m +nadgrids=@null +wktext +no_d " CONNECTIONTYPE OGR NAME "Counties_Labels" STATUS DEFAULT TYPE ANNOTATION PROJECTION"+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=-40 +x_0=0.0 +y_0=0.0 +k=1.0 +units=m +nadgrids=@null +wktext +no_d" END LABELITEM "NAME" CLASS LABEL OUTLINECOLOR -1 -1 -1 FONT FreeSans SIZE 10 TYPE truetype COLOR 0 0 0 FORCE TRUE END ENDEND ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Status of Java MapScript?
Hi Stephan, I'm the mantainer of java mapscript and while I have not been working on it for quite some time, I am stil successfully using it in a couple of projects (one is a fairly complex webgis).

Re: [mapserver-users] Compiling with opengl support
Felipe, opengl support should compile and run in the trunk version of mapserver, you'll have to do a checkout if you want to try it out. please report back the bugs you see ;) -- thomas On Tue, Feb 22, 2011 at 16:38, Felipe Alcacibar wrote: > Hi, i am trying to compile mapserver with the experimental opengl > support for experimental proposes too, but i cannot do it, i am using > mesa opengl, gentoo 64bits linux system and mapserver 5.6.6 but it > seems like this little problems that i cannot figure =/. > are a solution to this, i need another library, another implementation > of opengl? > > mapogl.cpp: In function ‘int msPopulateRendererVTableOGL(rendererVTableObj*)’: > mapogl.cpp:225: error: invalid conversion from ‘void (*)(imageObj*, > shapeObj*, colorObj*, double, int, double*)’ to ‘void (*)(imageObj*, > shapeObj*, strokeStyleObj*)’ > mapogl.cpp:242: error: invalid conversion from ‘void (*)(imageObj*, > shapeObj*, void*)’ to ‘void (*)(imageObj*, shapeObj*, imageObj*)’ > mapogl.cpp:243: error: invalid conversion from ‘void (*)(void*)’ to > ‘void (*)(imageObj*)’ > > wait for your ansewers, thanks in advice. > > Felipe Alcacibar Buccioni > ___ > mapserver-users mailing list > mapserver-users@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/mapserver-users > ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] Compiling with opengl support
Hi, i am trying to compile mapserver with the experimental opengl support for experimental proposes too, but i cannot do it, i am using mesa opengl, gentoo 64bits linux system and mapserver 5.6.6 but it seems like this little problems that i cannot figure =/. are a solution to this, i need another library, another implementation of opengl? mapogl.cpp: In function ‘int msPopulateRendererVTableOGL(rendererVTableObj*)’: mapogl.cpp:225: error: invalid conversion from ‘void (*)(imageObj*, shapeObj*, colorObj*, double, int, double*)’ to ‘void (*)(imageObj*, shapeObj*, strokeStyleObj*)’ mapogl.cpp:242: error: invalid conversion from ‘void (*)(imageObj*, shapeObj*, void*)’ to ‘void (*)(imageObj*, shapeObj*, imageObj*)’ mapogl.cpp:243: error: invalid conversion from ‘void (*)(void*)’ to ‘void (*)(imageObj*)’ wait for your ansewers, thanks in advice.

[mapserver-users] WFS Filter Encoding and resulting DB-queries
Hello list, while playing with MapServer WFS Filter Encoding capabilities I found some strange things when it comes to form the DB-queries (the requested layer is PostGIS-driven). It seems that there will always be a full table-scan and later on the FE will be applied. Is this done by design? Using URL-substitutions of the Search-keyword and apply it to a FILTER-element the resulting SQL-query has the given WHERE-filter set. But this opens the door for SQL-injections AFAIK. Setting the validation pattern is a little prevention. Are there any other ways to realize a keyword-driven search with MapServer beside FE IsLike or FILTER-substitution? I am using MS 5.6.5 on debian stable.
