Thanks, as you say this doesn't really solve my problem but it is a useful tool, as was SpaceEyes3D Viewer color-relief editor.
In exploring my problem I've written some Java code to interpolate shades within a color_text_file. If you set up a color-text-file with color differences at 1000 meter intervals, this code will fill in equally spaced colors at 100m (or any increment you want) to produce a file with lots of shades. If anyone is interested I can provide the code for this. If anyone is interested in this let me know and I'll send you a copy.

I suppose it wouldn't be too much of a stretch to interpolate between the colours it generates for a full 256 pallette. -JD ________________________________ From: gdal-dev-boun...@lists.osgeo.org [mailto:gdal-dev-boun...@lists.osgeo.org] On Behalf Of Mark Millman Sent: 15 October 2010 01:17 To: gdal-dev@lists.osgeo.org Subject: [gdal-dev] gdaldem color-relief color_text_files I am in need of some color_text files to use with the gdaldem color-relief utility to create color relief versions of Slope, Aspect, Roughness, TRI, & TPI maps. I seems to me that these ought to be pretty standard and as my skill set is on the developer side rather than the cartographer side of things I am hoping that some generous cartographer out there has already created some eye candy quality color_text_files for this purpose. Thanks in advance.
