Hi folks,
I think I am getting the hang of surfaces. Just a quick, and I hope, simple
question. When you are setting color=rules for elevations, how do you
indicate what levels you want to change colours? For instance, you wanted
the lower 0 to 100m to be green and 100 to 200metres to be yellow, how would
this be expressed when you are typing out the color=rules?
Sincerely
Kurt

May be not the canonical way, but works for me:
0 green
99.999 green
100 yellow
200 yellow
lets say: I care about 500--1000m. I'd do something like this:
0 101 101 101
499.999 101 101 101
500 blue
750 green
1000 yellow
1000.001 204 204 204
10000 204 204 204
This gives you dark grey for all land below 500 meters, a
blue-to-green-to-yellow gradient for lands 500--1000 m high, and light
grey for terrain above 1000 m.
Best,
