Study on Geographic Information Database Updating Approach
With the extensive application of massive geographic information database and the increasing demands of geographic information actuality, geographic information database update is becoming important. With incremental updating, it can satisfy some demands of real-time updating for geographic information system and geographic information service, improve updating efficiency, and reduce historical database expansion. This paper discusses the incremental updating method of geographic information database based on feature matching. At present this method was already applied in fundamental geographic information database of Fujian Province, which plays a satisfactory role. Procedures developed in this paper are based on ArcGIS geodatabase, which does not consider entity data organization, which need to be discussed further.
