Postal Fabric Generation

摘要

A postal code map and related data constructed of polygons representing multiple-digit postal codes and defined by attribution information and/or other spatial features thereby providing more granular and precise entities to optimize activities such as trade area analysis and visualization. The polygons are created and illustrated by generating Voronoi tessellation based on the location of high precision address points and/or interpolated address points, multiple-digit postal codes of each and, for further refinement, attribution information and/or other spatial features such as streets, roads and highways; water borders and boundaries; rail lines; and park, city, county and other municipal, commercial and residential boundaries or barriers to further enclose, restrict and/or define the resulting polygon limits of the visual map.

主权项

1. A method to provide postal data using a polygon fabric representing multiple-digit postal codes, comprising:
determining addresses of a postal area and multiple-digit postal codes of each; creating Voronoi cells of the postal area including addresses of each respective multiple-digit postal code; modifying a boundary of a Voronoi cell based upon spatial feature information of the postal area; combining Voronoi cells if they have a shared border; and providing a postal map comprising a plurality of Voronoi cells.
