TAP™ Mapper Data Summation analysis is the summation of point data from point-type shapefiles over geographical areas covered by polygon-type shapefiles. The most common Data Summation usage is for conducting population counts wherein the population covered by a tile-type area coverage study is calculated by adding up the population residing within the areas covered by RF signal strength at user defined levels of interest. U.S. block centroid population data for the 2000 and 2010 census are available from SoftWright to facilitate population counts, which are often required for public safety communication systems.
