Abstract: Considering the current technical and financial feasibilities in practical applications,this paper studies on the design aspect of the efficient software system for GIS database update based on geospatial images,in which the operation mode of integration is emphasized;next,a brief discussion of the system function architecture also is included;finally,the integrated software system Geomapupdate for national 1:50000 GIS database update based on geospatial images is introduced,as a typical case study.It is a platform exclusively servicing the current GIS database update businesses of our country and supported by National Geomatics Center of China(NGCC) and designed by the research group of State Key Laboratory of Information Engineering in Surveying Mapping and Remote Sensing(LIESMARS) Wuhan University.Practices manifest that Geomapupdate is a successful case study attempting to realize the highlighted integration concept for GIS database update;and it is able to improve the traditional update efficiency by more than 20%,which has been witnessed in the 1:50000 GIS database update business of China recently and laid a base to achieve rapid updating GIS data.
