Aloha. I want to extract concentric, terrain-following, flight paths for an aircraft (as waypoints) from the elevation data (x,y,z) for a volcano. This means I need to calculate polygons at equally-spaced horizontal intervals. Most contouring tools that I’m aware of only do contours for z.
I can think of ways to write this de novo but would rather not re-invent the wheel. I wonder if anyone can suggest something that already does this?
Mahalo. J
