The existing map-making is based on precise surveying and mapping or aerial photography for geographic pattern and position coordinates. With reverse order process

a new accurate digital traffic cartography method without surveying and mapping is developed. The method acquires vector map via intelligent extracting traffic network from the raster urban map

uses GPS track road(including accurate longitude and latitude)superposition in vector map to obtain map correction sampling control points

and completes map node coordinates of accurate calibration through the topological mapping. The key theoretical research results in the road clustering based on the road structure characteristics of raster map with closed-loop control and nonlinear calibration on the vector map by dynamic discrete topological transformation

thus the discrete nonlinear correction algorithm is put forward. The experimental map-making processes for the urban area of Hefei proved the validity of the cartography method with high precision.
