Here we’ll make use of two of our general ArcGIS Pro raster tools, the Focal Statistics tool and the Math with Raster Layers functions, to create a dataset called the Topographic Position Index, or TPI. The TPI is a really useful way to identify hills and valleys in the landscape based on a DEM, or Digital Elevation Model raster.
This lab exercise is one of a series of 13 that explore basic raster analysis and surface analysis in ArcGIS Pro. The full lecture and lab exercise document can be downloaded here:
