A simple Perl wrapper around the Google Maps API. It allows you to easily create maps with markers, polylines and information windows. You can now look up locations around the world without having to install a local database.
Gowalla said a writeable API was coming soon. Today, the check-in API is available to developers. Though it took longer than anyone expected, the announcement and the API have some nice aspects to help developers use the new features.
The geo mapping platform ecosystem has grown a little more as the competition between Google Maps and Bing Maps just got a lot more interesting. It's been less than a week since we covered the release of a variety of new features for Bing Maps, including the addition of new StreetSide panoramic imagery similar to that used in Google Maps StreetView. At the time, it seems that Bing Maps was making a move to "catch up" with Google Maps in terms of immersive street-level panoramic photos. And now Google has countered back with the release of "aerial perspective imagery" similar to the Bird's Eye View imagery used in Google Maps.
