II. d. Digital Elevation Model (DEM)
             Estimated time:
             2 minutes
A Digital Elevation Model is a grid in which each cell represents a different elevation. This can be a very powerful tool when it comes to watershed modeling. We are going to add some shading to our DEM to get a better view of the terrain.
In this exercise, you will:
  • Select a color ramp for a layer
  • Apply a “Hillshade” to the terrain
