How Can I Conduct Intersecting Contour Analysis with TAP™ Mapper?

Intersecting Contours provides a tool for the summation of point data from point-type shapefiles over geographical areas covered by a set of intersecting polygon-type shapefiles.  The most common Intersecting Contours usage is for conducting population counts wherein the population covered by the intersection of two sets of contour studies is calculated by summing the population residing within the area defined by the contour overlap.  U.S. block centroid population data for the 2000 and 2010 census are available from SoftWright to facilitate population counts. In the illustrative example below, a population count is conducted for a set of contour type area coverage studies created using TAP™.
