Skill Drill: Defining the Study Area

Raster processing can place significant demands on a computer’s processing power and memory. To save time during the analysis, you will limit raster processing to the areas around the den locations and the town of Orick. Use the Merge tool to combine the den locations and the town of Orick into one point feature layer.

The Merge tool combines data of the same type into a single dataset.

Use the resulting shapefile to create a 10-mile buffer around the town of Orick and den locations using the Buffer tool. Now that you have established a 10-mile buffer around the town of Orick and the den locations, you can use this layer in later steps to clip rasters to this geographic extent.

The buffer will be used to clip rasters and to define the geographic extent of the raster processing later on during this activity.
