Legacy Point In Polygon

The Legacy Point In Polygon component takes latitude/longitude coordinates and identifies the geographic area (or "polygon") in which the point resides. It can also determine the distance to a line when used with a database of lines, and the distance to a point when used with a database of points.

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.
Legacy Point In Polygon is used with a Centrus database (GSB files) and is part of the Spatial Module.
Note: This stage is deprecated. The new Point in Polygon stage should be used when creating a new dataflow (for more information, see Point in Polygon). Any existing dataflows that use this stage will continue to function properly until this legacy stage is removed.

To find a nearest point of interest, the user (or the role they belong to) needs EXECUTE permission on the Named table.
