This command creates a Carlson Triangulation file (TIN) by downloading surface data from Google Earth. While the elevation accuracy of the Google Earth surface should be considered coarse, it might be suitable for large-scale watershed modeling studies, preliminary land-planning studies or "proof-of-concept" preliminary designs.
