Map-Matching, integrate the vehicle positioning data with digital road networks an important positioning technique in the vehicle navigation and positioning system. Map-Matching as software technology, which can improve the positioning accuracy without increasing too much cost in equipments, is widely used in many systems. The paper is concentrated on data processing and Map-Matching in vehicle navigation system. Data processing includes the resolution algorithm of the GPS data, with combination of principle of coordinate transformation, changing the coordinate. As to the map-matching part, for Map-Matching algorithms new mapping method is adopted according to angle when driving, the algorithm is programmed and realized in Visual Basic 6.0. Consequently, highly matching precise and more fast matching velocity are obtained.
