Paper Abstract

In order to updating GIS database by GPS scientifically, reasonably and esthetically, the data of GPS and GIS must be fused effectively. A data fusion algorithm based on map matching was presented in this paper. First of all, GPS error buffer was constructed in the scope of GPS point, the data of GPS and GIS was fused according to the nearest distance, the most similar direction. The GPS point after fusion was added to GIS database. The topological relationship was rebuilt and database is updated. The simulated results show the data of GPS/GIS can be fused by this algorithm and GIS database can be updated in effect.
