Module 10: Vector Analysis 2

This week's assignment was to explore and implement multiple Overlay tools, as well as become familiar with ArcPy.  There are several Overlay tools in which features on a map, most commonly polygons, are spatially analyzed relative to each other.  The common Buffer tool was used to created polygon features surrounding roads and water (Lakes and Rivers), then Unions, Intersections, and Erases of these buffers were performed.  The ultimate goal was to selectively remove bits and pieces of an original buffer feature so that we had specific areas isolated.  The map above shows the product of this process.  Regions within a certain distance from access roads (one buffer layer) and within a certain distance of water bodies (another buffer layer), but outside of conservation ares (a third polygon layer) are highlighted as potential camping areas.
