Map matching
As mentioned, the GPS systems used by this Navigation System are susceptible to certain errors.
Their calculations may on occasion place you to a location on the map where no road exists. In this situation,
the processing system understands that vehicles travel only on roads, and is able to correct your position by
adjusting it to a nearby road. This is called map matching.
With map matching.
