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.) I am using MapServer 6.0.1 as part of MSW 3.0.3. Incorrect image being displayed: http://i44.tinypic.com/2hdwuuu.jpg Correct image, created through QGIS: http://i42.tinypic.com/21d2x5h.jpg Here is the LAYER portion of my map file.

RE: [mapserver-users] gradient display of raster DEM data
John, Take a look at the gdaldem utility. http://www.gdal.org/gdaldem.html You likely already have it on your machine already. Aside from being able to generate data products like slope grids, it can produce hillshade images or color relief maps. David.
