How do you make a 3D topographic map?
The basic process is as follows: 1 Get digital elevation data for the area you wish to model. You will typically download that data as a GeoTiff file. 2 If necessary, crop the section of interest from the larger dataset. 3 Convert that data to a DEM file. 4 Make a 3d model based on the data. 5 Print and enjoy.
