wow,
Fixed levels is what you want. It is a list of levels to contour at.
-fl 0 10 20 30 40 50 60 70 80 90 100 150 200 250 300 350 400 450 500 700
800 and so on.

Hi,
I want to generate contours with different intervals in sevaral elevation
ranges. For example, if the elevation range is (0,100), the contour interval is
10; if the range is [100, 500), the interval is 50; and if the range is [500,
2000), the interval is 200. Can all those contour genera
