AnnotatedEarth is a user-driven community for collecting location information. It is specifically designed to provide location-aware information to devices such as laptops, palm pilots, and cell phones via a service interface on the website. AnnotatedEarth is focused on determining what is immediately in the surrounding area (e.g. 20, 50, 100 feet away). Although usable with mapping services, AnnotatedEarth, as a system, doesn't directly provide for map creation or directions.
The AnnotatedEarth Location API enables developers to fully access AnnotatedEarth's location-aware infrastructure and information.
