Actually, I want to show the DEM as a colour-coded elevation raster. However, I also want to incorporate the hillshade model. I think I can do that by setting the OPACITY of the hillshade.

In addition to that, you can have your DEM as a second layer that is not displayed, but is available for query. I don't think that I have ever used the raster query functionality, but you can find some info here: http://trac.osgeo.org/mapserver/wiki/RasterQuery http://mapserver.org/input/raster.html#raster-query Is this what you were thinking?

Can I set the transparency of a layer? Is there a GDAL utility for rendering a combined hillshade/elevation model which will still retain the original elevation values for query? =========================== David V.

David. From: [email protected] [mailto:[email protected]] On Behalf Of David Hildebrand Sent: Wednesday, November 03, 2010 6:25 PM To: [email protected] Subject: [mapserver-users] DEM display I have an SRTM file in TIF format which I want to display in a shaded relief but I'm not sure of the approach I should take. Do I need to define classes and symbols for the layer (that would not help for the hillshade) or should I execute a script (PERL) on the server to create the image I need on the fly? Thanks for the tips. =========================== David V.
