Raster Lab 6: Using the Reclassify tool in ArcGIS Pro

In this exercise we’ll try out one of our general raster tools that we discussed in Lecture Video 1, the Reclassify tool, and we’ll also see one way to clip a raster dataset to a polygon using the Extract by Mask tool. We will reclassify our Aspect raster from Lab Exercise 1 into North, East, South and West-facing categories, plus flat areas, and then we’ll calculate the areas and proportions of each direction category in our management unit polygon. Along the way we’ll also demonstrate the Calculate Field tool, and see how to copy a layer by selecting it, holding down the [Control] key, and dragging the layer up or down in the Contents.

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:
