Does anyone know of an app that would speed up the creation of contour lines from, say, a Google Earth terrain map?
Doing it longhand, the general method seems to be to create a series of planes at useful vertical intervals. You then intersect with model to create the contour lines. Finally, you use sandbox tools to collapse the contour lines onto a flat plane. It isn’t hard but I imagine it could be automated. All the user might need to input would be the vertical intervals.
