Map Matching

Any global satellite positioning system (GNSS) like GPS, GALILEO or GLONASS, which is used for real-time positioning includes inevitable errors. Additionally, there's no (and will be no) absolutely accurate digital street map representing the real world. Therefore, in order to show a vehicle's position on a digital street map you have to match ("snap") it's coordinates (received from a global positioning system) on top of a vector based street map. This challenging process is called "Map Matching".
