Using Regions

You can easily perform many interactive geospatial analyses by learning how to use regions. A region consists of one or more polygons that you can create interactively in many ways, such as drawing, query, buffer zones, element selection, and point clusters. As soon as you have created a region, it can be used in operations on multiple layers of raster, vector, CAD, and TIN geodata.
