Postal Fabric Generation
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.
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.
2 . The method of claim 1 , wherein spatial feature information comprises one or more of streets, roads and highways; water borders and boundaries; rail lines; and park, city, county and other municipal, commercial and residential boundaries and barriers of the postal area.
3 . The method of claim 2 , wherein the boundary of the Voronoi cell is modified to expand, contract or divide to conform to the spatial feature information of the postal map.
4 . The method of claim 2 , wherein an element of the spatial feature information is weighted relative to other spatial feature information to affect the Voronoi cell modification.
5 . A postal map of a polygon fabric representing multiple-digit postal codes, comprising:
a plurality of Voronoi cells including addresses of a postal area and multiple-digit postal codes of each, wherein a boundary of a Voronoi cell is modified based upon spatial feature information of the postal area, and wherein Voronoi cells are combined into a single cell if they have a shared border.
6 . The postal map of claim 5 , wherein spatial feature information comprises one or more of streets, roads and highways; water borders and boundaries; rail lines; and park, city, county and other municipal, commercial and residential boundaries and barriers of the postal area.
7 . The postal map of claim 6 , wherein the boundary of the Voronoi cell is modified to expand, contract or divide to conform to the attribution information of the postal area.
8 . The postal map of claim 6 , wherein an element of the spatial feature information is weighted relative to other attribution information to affect the Voronoi cell modification.
9 . A method to provide a postal map, comprising:
creating Voronoi cells of a postal area including addresses of each respective postal code of the postal area;
modifying a boundary of a Voronoi cell based upon spatial feature information of the postal map;
combining Voronoi cells if they have a shared border; and
providing a postal map comprising a plurality of Voronoi cells.
10 . The method of claim 9 , wherein spatial feature information comprises one or more of streets, roads and highways; water borders and boundaries; rail lines; and park, city, county and other municipal, commercial and residential boundaries and barriers of the postal area.
11 . The method of claim 10 , wherein the boundary of the Voronoi cell is modified to expand, contract or divide to conform to the attribution information of the postal area.
12 . A method to provide a postal map, comprising:
creating Voronoi cells of a postal area including addresses of the postal area;
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.
13 . The method of claim 12 , wherein spatial feature information comprises one or more of streets, roads and highways; water borders and boundaries; rail lines; and park, city, county and other municipal, commercial and residential boundaries and barriers of the postal area.
14 . The method of claim 13 , wherein the boundary of the Voronoi cell is modified to expand, contract or divide to conform to the attribution information of the postal area.
