POLYGON OVERLAY Add-In

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.

Installation

2. Open a map with the two area layers to overlay.
3. Choose Tools-GIS Developer's Kit-GISDK Toolbar to open the GISDK toolbar.
4. Compile this file in test mode using the first button (Compile).
