I am investigating on how to find the nearest zip code from another zip code based on distance. I am working on a dealer locator solution.
I was wondering if anybody else has done this in Rbase. I am thinking there is an additional data field needed to determine the physical location(maybe latitude and longitude??). I am not sure. I know there are hosted solutions but I am looking for an in house solution to save some $$$. TIA Dan Goldberg
