Description
> > Having seen your excellent web page on SDLs > (http://mapserver.gis.umn.edu/doc44/sld-howto.html), I wonder if you > could advise me on how I can features differently, based upon spatial > location. An example would be showing schools as red points within a > particular bounding box, whereas outside the bounding box, they would > appear black. > > > > The WMS specification alludes to it, but doesnt provide a concrete > example, that I can see. > Hi There, Check at these urls (and the slds) : it will give you an idea on how to acheive that. Basically you need to do it in 2 separate requests : * first request is a regular wms get map request all all elements drawn in the default way that you want (an sld might me used or not) * the second request will use an sld with a filter encoding bbox element that will only select elements inside a region and draw them accoring to waht is defined in the sld. http://www2.dmsolutions.ca/cgi-bin/mswms_world?SERVICE=WMS&VeRsIoN=1.1.1&Request=GetMap&LAYERS=WorldGen_Outline&SLD=http://www2.dmsolutions.ca/msapps/world_testdata/tests/sld_tests/sld_line_simple_spatial.xml http://www2.dmsolutions.ca/cgi-bin/mswms_world?SERVICE=WMS&VeRsIoN=1.1.1&Request=GetMap&LAYERS=WorldGen_Outline&SLD=http://www2.dmsolutions.ca/msapps/world_testdata/tests/sld_tests/sld_line_simple_spatial2.xml
