Is there a way to use TranzDEM with existing elevation data and an historical topographic map, using the contour lines on the map, to erase a lake where historical rails are under water?
basically, can TranzDEM or MicroDEM (or any other open and free GIS software) "Read" and produce a terrain from contour lines?
I guess I really know the answer to this, but maybe someone has an idea of getting the results i'm looking for. I am really only interested in creating historical routes, and I need a way to replace the big flat spot of a lake with the original terrain from before the dam was built, perhaps using information from topographs that were made before the dam was.
TIA!
