Hi,
I have a list of zipcoded in a MySQL Database together with their Latitude & Longitude data (Column names: ZipCode, Lat, Lon).
Now I have to make a search requests (search for the zipcode) to extract information from a website. When I make this search requests the results include all information within a radius of 50km of the zipcode.
Now, I don't want to make an unnessary high amount of search requests, so I would like to minimize the amount of zipcodes. So I'm looking for a way to filter all zipcodes, so that I have only the zipcodes where the distance between them is >50km.
Unfortunately I have no idea how to to it. Can someone help me to solve this?
