I am working on a section of the D&G.R.W. narrow gauge Between Chama and Alamosa. There is a section that has elevations greater that 3000m that the railroad runs through. The tools in surveyor stop working at 3000m. You cannot smooth a hill, level a road or railroad or mess with anything that will make any changes outside of the original TransDEM height placement on the map without that section of landscape dropping automatically to 3000m. To do anything above the 3000m threshold flattens your map to a plateau, losing the build made with the TransDEM import. This question I have is in two parts. 1. Can I adjust the ability to work on landscape above 3000m? or Is there a way to drop the height for the entire route by 500 meters to the peaks remain in tack along with the railroad?
Thanks for any suggestions
