Create a design surface from the Site Scan DTM

Site Scan is now producing Digital Terrain Models (DTM) as TIFF files. Our processing engine generates the DTM by removing the vertical features that are not “ground” or “road surface”. How do you use this data? You can create a surface in Civil 3D directly from that file by following these steps:

1. Download the DTM (Tiff) from Site Scan. (If the DTM is not showing, reprocess the flight data).

 2. Select : Home > Surfaces > Generate a surface from DEM

3. On the File name type *.* and hit ENTER (to view all the files in the folder). Select the DTM tiff File

The surface will now be created
