Databases

Legacy Point In Polygon works with databases of polygons, lines, and points.

• Polygon databases—These databases define the boundaries of the polygons that Legacy 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, lines, or points that are of interest. You can purchase these databases from Pitney Bowes. For a list of available databases, see Spatial 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.
