How do you make a 3D topographic model?

The basic process is as follows:

1. 1 Get digital elevation data for the area you wish to model. You will typically download that data as a GeoTiff file.
2. 2 If necessary, crop the section of interest from the larger dataset.
3. 3 Convert that data to a DEM file.
4. 4 Make a 3d model based on the data.
5. 5 Print and enjoy.
