System Design for Automated Quality Control of Geodata by Integration of Gis and Imagery

Describing the quality of digital geodata in a geodatabase is required for many applications. We present our developments for automated quality control of the area-wide available topographic vector data set ATKIS in Germany using images. To reach an efficient solution our concept is designed as an automated system, which comprises automatic cartographic feature extraction and comparison with ATKIS. By integration of image analysis and GIS both tasks are triggered by additional knowledge derived from the existing scene description. Our concept admits user interaction to perform a final check of the fully automatically derived quality description of the data to reach an operational solution.
