Abstract
Advanced Vehicle Location (AVL) needs accurate vector maps. This paper presents a discrete topological transformation to get vector map nonlinear geo-adjustment. The new algorithm adjusts a sample point by a sample point. At the time of adjusting one point, the algorithm also automatically adjusts all its neighboring area points within a block/polygon area keeping their topology. If the selected sample point set has enough distribution, then the vector map will have an accurate adjustment for all map points because the total nodes on the map is very limited on the vector map. Example shows the effectiveness of the new method on vector map automatic geo-adjustment.
