Point In Polygon works with databases of polygons and databases of lines.
- Polygon databases—These databases define the boundaries of the polygons that Point In Polygon uses for its analysis. If we were to use a database of Congressional districts instead of flood plain and sales territory databases, we could identify the name of the person that represents the residents of the home; if we used a database of ZIP Codes, we could determine the ZIP Code for the home.
- Line databases—Line databases define things like fault lines, coastlines, and hurricane tracks. Using buffering you can determine if a point is within a certain distance from a line.
- Point databases—Point databases define a specific point, for example the location of a hail storm. Using buffering you can determine if a given location is within a certain distance from the point.
To perform Point In Polygon analysis, you must first obtain a database that contains the
polygons or lines that are of interest. You can purchase these databases from Pitney Bowes. For a list of available databases, see Location Intelligence Module Databases. You can also create user-defined files
to define areas or lines of interest to your particular organization, such as sales
territories or insurance rating territories. For more information, see User-Defined Centrus Databases.
