i have created a geotiff “.tif” in civil 3D to import into RAS Mapper. As i am a novice at this and just learning RAS mapper im having a little trouble. The “New Terrain” tab under the Tools menu looks like it wants to convert a selected file to a geotiff, therefore it is giving me an error…..help.
What is the specific error? I ask because when I export surfaces from AutoCAD, RAS does not recognize the horizontal datum, which resulted in an error and the terrain cannot be processed. Try importing the surface to ArcGIS and then export it using the correct datum.
