I bought a GEOIP database and store every single post long lat data in mysql. After that i just implement the Google Map API by passing dynamic longlat data to the Google MAP. What I get is all my post shown in the Google Map and also display nearest post from a certain location
What you need is a GEOIP database, A query that calculate distance in miles base on given longlat, Google API, PHP Dynamic passing API variables.
example of my site : Matchimedia.com.
