Point in Polygon

The Point in Polygon component takes either a geometry (a point) or longitude (X) and latitude(Y) coordinates and identifies the geographic area (or "polygon") in which the point resides by searching a named table of polygons. It can also determine the distance to the edge of a polygon.

Note: This stage does not support the GSB file (Centrus database) format. When migrating dataflows from the Legacy Point in Polygon stage to the Point in Polygon stage, the data in the GSB files must be obtained in either TAB or shapefile format.

Polygons can be defined to represent the specific spatial characteristics you are interested in. For example, you may be interested in areas like flood plains, congressional districts, or sales territories. Additional examples include:

  • Banking—Identify market penetration in neighborhoods surrounding individual branches.
  • Insurance—Identify rating territory, flood zone, or distance to the coast.
  • Retail—Target messages in a catalog, direct mail piece, zoned newspaper ad, or billboard to a specific market.
  • Telecommunications—Determine if a prospect is eligible for DSL service.

Point in Polygon is part of the Location Intelligence Module. For more information about this module, including a listing of other components included with it, see Location Intelligence Module.

ACL Authorization Flow

To find a particular point in a polygon by searching the named table, the user (or any roles they belong to) will need Execute permissions in the following manner:

  • “EXECUTE” for entity type “Location Intelligence.Named Resources”
