Beschreibung
In this paper, we establish a novel multistep procedure for morphologic characterization of built environments in terms of built-up height and density. We rely on elevation measurements from the TanDEM-X mission (TDM) and multispectral Sentinel-2 imagery. These earth observation systems feature a notable tradeoff between a fairly high spatial resolution and large-area coverage and, thus, allow for spatially continuous analysis of built environments around the globe. To this purpose, we follow an automated workflow that foresees the distinction of “built-up” and “non-built-up” areas by relying on the so-called Global Urban Footprint processor. This information is deployed within a tailored filtering procedure for the TDM digital surface model data to extract elevation information for built-up areas. Subsequently, the intra-urban land cover is mapped under consideration of Sentinel-2 imagery and serves as basis to …
