DSM-to-LoD2: Spaceborne Stereo Digital Surface Model Refinement [PDF]
Remote Sensing, 2018 A digital surface model (DSM) provides the geometry and structure of an urban environment with buildings being the most prominent objects in it. Built-up areas change with time due to the rapid expansion of cities. New buildings are being built, existing

IOP Conference Series: Materials Science and Engineering, 2019 Abstract Digital Elevation Model (DEM) is an important component in flood inundation modelling as a part of flood risk analysis. However, Digital Surface Model (DSM) which still contains noises of artefacts is more common to be available than DEM. Then DSM misleads the inundation extent.
