Point-in-Polygon allows you to determine whether or not a given geocoded point lies inside a polygon drawn on a map.
The buffer zone around the polygon is defined, allowing you to determine if the point lies well within the boundary, near to the boundary but inside it, near to the boundary but outside it, or well outside the boundary.
GIS applications separate the different types of information into data "layers." For example, store locations might be defined in on one layer and main roads on another.
Use the Point-in-Polygon tab to determine which data layers are available to the Point-in- Polygon module. You can add data layers that are already in .gsb format, such as the States.gsb and Counties.gsb files. You can also import layers from third-party data providers.
