Buffering Data
Concept: The purpose of this exercise is to show how to create buffers around both a point and polygon. You will create a single area buffer around a county polygon shapefile and multiple ring buffers around a set of point shapefiles. Note: the rings should be dissolved to create a single area. The basemap layer will be displaying an entire state. Download a map of a county and create a 15 mile buffer around the county border. Download point data from a source and create a three ring buffer around at 10, 20 and 30 miles. Make sure to dissolve the multiple rings so that there is no overlapping. Insure that a background map is used with the buffering. You may use the data sources provided or select your own data.

Requirements: Provide your instructor with two different screenshots of the two types of buffers. One screenshot should be the buffer of a polygon shapefile around a county and the other a dissolved multiple ring buffers around points. Provide your map package.
Grading:
40% on buffering of a polygon
60% on the multiple ring buffers with dissolving
Additional points can be awarded for creativity.
