Quality Control and Updating of Road Data by Gis-driven Road Extraction from 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 German topographic vector data set ATKIS using images. The automation comprises automatic cartographic feature extraction and comparison with ATKIS data, which both are triggered by additional knowledge derived from the existing scene description. To reach an operational solution the system is designed as an automated system which admits user interaction to perform a final check of the fully automatically derived quality description of the data.
