[gdal-dev] gdaldem color-relief color_text_files

[Mark Millman]

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.

This isn't quite what you need, but for creating thematic colour
schemes, http://colorbrewer2.org/ is a rather neat tool. I suppose it
wouldn't be too much of a stretch to interpolate between the colours it
generates for a full 256 pallette.

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.  Mark
