visible and infrared channels, use of both first and last pulse
laser scanner data) and development of the change detection
method (e.g. matching of detected buildings with buildings of
the map and use of advanced comparison strategies). However,
the results obtained with the current methods in our study areas
already suggest that automatic building detection and change
detection is possible and could produce useful results for map
updating.
