TanDEM-X & UAV data for modeling 3D vegetation information in urban areas

摘要: While 3D information on cities has been frequently assessed in recent years, this is mainly limited to the built-up area. vegetation for assessing urban ecosystem services such as carbon sequestration or cooling, example, missing most cities. New data and methods calculating characteristics including remote sensing techniques offer large benefits addressing lack of information. Within ongoing project aim test different state-of-the-art remote-sensing based modelling areas. For purpose, parameters two spatial scales were chosen: TanDEM-X a city unmanned airborne vehicles (UAV) point cloud micro scale. The paper present approach preliminary findings possibilities challenges 3 D vegetation. In first step we applied morphological approaches assess normalized digital surface model (nDSM) afterwards. We able generate an initial DEM, DSM nDSM, respectively.
