Airborne photogrammetry and lidar for DSM extraction and 3D change detection over an urban area – a comparative study
2013
International Journal of Remote Sensing
Cornelis Stal and Frederik Tack equally contributed to this article and are listed alphabetically. A digital surface model (DSM) extracted from stereoscopic aerial images, acquired in March 2000, is compared with a DSM derived from airborne light detection and ranging (lidar) data collected in July 2009. Three densely built-up study areas in the city centre of Ghent, Belgium, are selected, each covering approximately 0.4 km 2 . The surface models, generated from the two different 3D acquisition
