A method for automatic updating of building data bases from Digital Surface Models (DSM) and a normalised difference vegetation index is evaluated. The DSM can be generated from Airborne Laserscanner (ALS) data or by image matching techniques. Buildings are detected automatically from the input data. The building detection results are compared to an existing building data base, and changes between the existing data base and the new data set are determined. Buildings and building parts are… CONTINUE READING
