I have a Postgres database of entire U.S. zipcodes and their lat/long data.
My requirement is to divide these zipcodes into non overlapping regions.
All regions have some center zipcode. All regions grow outward, starting from it's center until they intersect with another region.
EDIT: I do not have information about the radii/sizes of the regions. All I have is a list of zipcodes that can be considered as centers of the regions.
Is this achievable using Postgis?
