The CommunityViewer (CV) GIS software (http://proximityone.com/cv.htm) site analysis tool is used to select geography for analysis in the DDA Viewer. Census tracts are used in this application.
The geographic area codes are saved to a file that is then processed by the DDA Viewer.
Using CommunityViewer GIS
A CV GIS project is opened. The following project view shows the Columbia, SC place (green fill pattern) and black census tract boundaries.
A zoom-in view is created and census tracts are labeled. For example, (above the red circle boundary), the code 45079000700 is the combined state (45), county (079) and Census 2010 tract (000700) uniquely identifying this tract among all 73,057 tracts covering the U.S. The name of this geocode field, used in CV and DDA, is "GEOID".
Cherry pick or use circle/radius selection tool to select areas to be included in selection file. In this application, three tracts are selected. When the site analysis operation is completed, the geographic selections file is created and ready for use in DDA.
