This add-in lets you overlay two area layers and create a geographic file
of the intersected areas with a table of the percents of overlap. The table
has the IDs for the new areas, the IDs of the original areas, and the
percents of the original areas that are inside the new areas. You can add
the new layer to the map, join it to the first area layer, then join the
resulting dataview to the second area layer, and use those attributes to do
additional analysis.
