The usefulness and acceptance of geo-information systems are mainly depends on the quality underlying geo-data. This paper describes a novel system for semiautomatic control existing topographic geo-spatial data via automatic image analysis. goal is to reduce manual effort GIS database minimum. core semantic network in which different analysis operators can be included. created specific applications, i.e., object classes most relevant. Images used aerial images, high-resolution satellite imagery, low-resolution imagery. A prototype has been use several years at public mapping organizations. From experience gained during this time, we give detailed report performance an evaluation results.
