FourCorners Framework
The FourCorners Framework provides support for the GPS plugin in iStumbler. It includes classes for talking to GPS devices as well as support for modeling Geographic Points and Locations.
Active development on the framework is focused on simplifying the threading model, supporting a live updated map and adding better support for bluetooth gps devices.
The FourCoorners Framework is based on the FourCoordinates framework.
