摘　　要：针对'十一五'我国1∶5万基础地理信息更新的任务需求,研究了基于影像综合判调的一体化更新作业模式,并设计开发了1∶5万基础地理信息综合判调更新软件系统。目前,该软件已应用于我国1∶5万地理信息更新工程,有效地提高了更新生产的效率,控制了作业质量、降低了作业成本,为我国1∶5万基础地理信息综合判调更新提供了高效的作业平台,也为1∶1万甚至大比例尺的数据更新提供了很好的借鉴。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 up- date 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 inte grated 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.
