The Google Geocoder API transforms addresses into geographical locations with coordinates. This official Java library has the potential to expand functionality due to the other APIs that include directions API, distance matrix API, elevation API, geocoding API, roads API, and time zone API. Working with this library could facilitate automatic rate limiting, retry on failure, easy authentication, and asynchronous & synchronous requests.
Twitter co-founder Biz Stone has just announced a new geolocation API that will be available to developers fairly soon (Twitter API profile). The new API, which will likely be rolled out in Twitter clients before being available on the Twitter site, will allow users and developers to add latitude and longitude to tweets, thereby adding a valuable new layer of meta information to tweets.
Do you know anyone with a car glovebox full of inked-up road maps? What a waste of paper (and ink!). Using Google Maps is, of course, the preferred method to mark up maps. One tool that makes it especially easy is Scribble Maps. And now it's testing "pro" features, a fee-based service with even more features.
