Massachusetts Community College Proximity

This map shows the 20 mile proximity of the 19 community colleges in Massachusetts in 3 different ways.  The blue shows a general 20 mile buffer around each of the 19 community colleges.  The red areas are the areas of Massachusetts that are outside of this 20 mile are and were produced through the use of the euclidean distance tool, I left the areas within the 20 mile limit hollow (uncolored) so you could see the buffer layer.  The last part of this analysis was done through use of the network analyst extension and use of a service area analysis.  This result shows a 10 mile area in dark green and a 20 mile area in bright green.  These three analyses are then stacked so you can see the differences between the 3 methods.
