Framework for listening to GPS devices from your Mac.
FourCoordinates is a Mac OS X framework written in Objective C for listening to GPS devices connected to Mac computers. It takes care of interpreting the output of the GPS device and presents you with a simple class interface for obtaining the current coordinates, and being notified when they change. Its goals are ease of integration, zero user configuration (i.e., autodetection of GPS devices), and support for a broad range of GPS devices. It includes a demo application called WhereAmI, which displays current GPS information.
