[mapserver-users] RE: DEM display

How can I combine a pre-rendered hillshade model with an elevation
layer?  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?

I would pre-render all of my hillshades and then add them as simple
raster layers.

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.
