Creating watershed maps for schools. I want to color ramp the elevation to show low and high points. What kind of files do I need and where to find them?
See the discussion here
about improved color ramps.
Note that you have to edit the color ramp's first column (the elevation divisions) to fit your DEM's highest and lowest elevations. It took me some time to figure it out, but I did manage to get some good-looking color relief maps.
