Airborne LiDAR has become the main technology to provide data for Digital Surface Models (DSM) and Digital Elevation Models (DEM) for various purposes, including orthorectification. At the same time, digital line scanners such as the ADS provide multiple stereo coverage, which can be used for image-based DSM/DEM derivation. Besides saving the LiDAR acquisition cost, such data provide several advantages over LiDAR results, especially since orthoimage generation can be based on the same data set…
