REVISION OF TOPOGRAPHIC DATABASES BY SATELLITE IMAGES

This paper examines data from different sensors regarding their potential for an automatic revision of topographic databases. The data which have to be updated are from the German national topographic cartographic database (ATKIS) and were captured in the scale of 1 : 25,000. After a brief introduction into ATKIS the used approach is discussed. Results are shown on examples of data from several sensors: scanned analogue aerial photos, an airborne digital line scanner (DPA camera system), the Indian satellite IRS-1C, the MOMS-2P camera and from a laser scanning system as an additional information source.
