【Abstract】 Road network data is the foundation of transportation analysis,research,planning and design.The transportation departments usually need to update their road network by referring to the data from different recourses.Therefore,the up-to-date data should be secured as well as the inheritance of temporal versions.Considering the present situation,the paper presented a method,which can automatically recognize and update the incremental data quickly and accurately by referring to the new collected vector road data.Much time and manpower used for updating and maintaining the road network data every year can be greatly reduced.更多还原
