Bing Maps Java SDK provides a Java wrapper to Microsoft's Bing Maps API. This allows developers to access the API's methods for searching for points of interest, getting driving directions, matching addresses to the map, and more. This project is currently open for adoption as the creator no longer has time to maintain it.
We're used to seeing start-ups built on top of APIs. We even wrote a series of posts to do it yourself. Fueled by the popularity of location-sharing site FourSquare, marketers are using the FourSquare API (our FourSquare API profile) to promote their products.
At the The Next Web Hackathon in Amsterdam, developers played with a lot of new APIs. One that caught our attention is the Gbanga Puppetmaster API. Gbanga is a location-aware gaming platform, intended for use with games where walking around within the real world matter. It's released one game, Gbanga Famiglia, a mobile phone-based app using a theme of mafia families taking over areas and finding loot. Much more exciting, however, is its API, which allows for quests within Famiglia, and other, separate location-based games.
