Google Maps API ( Get Locations Near Lat Lon )

when a user types a real world address into our website. We grab the latitude and longitude using a script , and use this to propagate a gMap.

However what I would like to do, is ...

If user types into search box, a suburb ( that is in our DB ) And clicks a checkBox , to include surrounding suburbs, how we could set a proximity code to search for that suburb 开发者_StackOverflow社区, grab the lat and long and also return results for other addresses within that radius , or in essence Get Locations near Lat and Long.

Does this make sense, ? I have been scrabbling around on Google all day, with no real luck.

I am sure there must be a way, or API or some formula, for displaying search results of locations within the vicinity of the original LAT LONG geo location.

Any help appreciated

There is the 'Google Places API' which is in 'limited developer preview', you have to request the required credentials to use it. See http://code.google.com/apis/maps/documentation/places/ for the details.

You could also use Yahoo's service to find places nearby according to Flickr, try the test console at http://developer.yahoo.com/yql/console/#h=select%20*%20from%20flickr.places%20where%20lat%3D43%20and%20lon%3D-94
