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

近年來，伴隨著信息化技術(shù)、計算機技術(shù)的迅速發(fā)展，地理空間數(shù)據(jù)更新技術(shù)已成為地理信息行業(yè)關(guān)注重點，基礎(chǔ)地理數(shù)據(jù)也從數(shù)據(jù)生產(chǎn)轉(zhuǎn)為數(shù)據(jù)更新[1]。（剩余5705字）
