Study on topographic map production base on Geo-information

After analog and digital mapping, it is now heading towards information-based map production era. How to provide high-quality, real time Geo-information products and diversified services has become the highlight in the information-based mapping stage. This paper elaborates on database-driven map production technical, a delta-based map products dynamic update solution, in order to provide new guidelines and new methods for product updating under the information-based mapping system. These technical guidelines have already been successfully applied to the national 1∶50 000 topographical map production.
