Twitter API: How to search only for geotagged tweets

Question

How can I use Twitter Search API (or other) to get a list of tweets which have the \"geo\" param?

--EDIT--

By example: I wont get list

Answer 1

From the Twitter API Documentation, this should be the format of your search query:

 http://search.twitter.com/search.json?geocode=37.781157,-122.398720,1mi

Where 37.781157 is the latitude, -122.398720 is the longitude and 1mi is the radius to search within.
