3D map is what makes Orbis special. The map is rendered in 3D, which gives you the true idea of the difficulty and the altitude profile of the course on which you are going.
Either the map keeps track of your current GPS position, or you can browse the map using usual touchscreen gestures. There is also a feature called LiveView, which, when activated, rotates the map according to the position of the phone, using both compass and accelerometer data.
Furthermore, there are many map sources available, and the application can be expanded with more sources. The 3D view is independent from the sources, therefore you can choose according to your preference.
