The navigation data can be used for automotive navigation systems using portable GPS devices e.g. Garmin Nuvi. With the data, the Garmin Nuvi can navigate to a specific address, a Point of Interest (POI), a recent location, a specific junction or your favourites. It also allows you to directly input a specific GPS coordinate and features Where Am I, a convenient menu that shows your exact position (latitude and longitude) as well as the nearest junction. You can also quickly find the closest hospitals, police stations and petrol stations in case of emergency. The navigation data is accurate to 10 metres and is crucial for vehicle tracking and fleet management systems.
