This map illustrates an ArcGIS spatial analyst allocation function. Allocation can determine where there is a shortage of parks in the City of Dallas. With a one-mile park allocation and an understanding of where residential land uses are, the map can help park planning officials determine where future parks are most needed. Park equity is another approach that could have been taken to see whether minorities and lower income groups are less served by parks. These types of tools can also be utilized in market analysis, site selection, and emergency preparedness applications.
