摘要：The usefulness and acceptance of spatial information systems are mainly dependent on the quality of the underlying geodata. Thispaper describes a system for semiautomatic quality control of existing geospatial data via automatic image analysis using aerial images,high-resolution satellite imagery (IKONOS and RapidEye) and low-resolution satellite imagery (Disaster Monitoring Constellation,DMC) with mono- and multi-temporal approaches focusing on objects which cover most of the area of the topographic dataset. The goalof the developed system is to reduce the manual efforts to a minimum. We shortly review the system design and then we focus on theautomatic components and their integration in a semiautomatic workflow for verification and update. A prototype of the system hasbeen in use for several years. From the experience gained during this time we give a detailed report on the system performance in itsapplication as well as an evaluation of the results
