Abstract： Hengyang City was taken as the research object to explore the method of linkage update of Hunan Province’s geographic information data of 1：10000. Incremental update and multi-scale linkage update were used as technical means to divide the responsibility grid. A current the geographic information database of 1：10000 was constructed to provide basic geographic information decision support for various departments and local governments.

Key words： basic geographic information; incremental update; linkage for data among province city and county; linkage update for multi-scale data

近年来，伴随着信息化技术、计算机技术的迅速发展，地理空间数据更新技术已成为地理信息行业关注重点，基础地理数据也从数据生产转为数据更新[1]。（剩余5705字）
