color raster to the road map automatic extraction, presents a closed-loop feedback extract color raster map the roads. Map images in the mathematical model, based on the target map of map features color image processing standard. Some of the algorithm used to remove noise from the road after the road is thinned. Based on road and noise characteristics to establish some criteria to judge the correctness of the road. Extraction of the road has become a criterion under constant amendments to the cycle path, the path of achieving automatic extraction. Test results show that the method has a high accuracy, fully automated and versatile.
