Google always give us some surprise, a new service named Google Transit has been released in beta test. With open API for Google Maps, nothing but your imagination stops you building creative applications.
Here is a wild idea to create the GPS application using Google maps:
- Build an Firefox plugin/standalone web server to communicate with GPSd, convert the NEMA format data to standard XML data source
More advanced features in mind:
- Cache Google map meta data and reuse it when offline.
- Voice navigation
