Work package D1: Processing and preparation of surface data


Contact information

Institution: DLR

Goals of WP-D1

Work package D1 aims at processing and preparing selected surface parameters required by the new UCM combining existing communal, federal and state geo-data (e.g. cadastral information) and remote sensing data. Remote sensing imagery is an area-wide available source of information on the land surface and built-up area. When applying automated processing and analysis techniques to this data, standardized geo-information products (e.g. surface parameters) can be generated for arbitrary regions of interest. The targeted basic surface parameters are e.g. the surface albedo, temperature, and the percentage of impervious/vegetated surface. These parameters can be derived from false color (CIR) aerial imagery and satellite data (e.g. Sentinel 2, expected launch June 2015). Enhanced surface parameters (e.g. green roofs, vegetation volume) require a very high resolution (VHR) digital elevation model (DEM) – e.g. derived from Laserscan data – and can therefore only be provided if such a DEM is available for the case study cities. Such VHR DEM data exists nowadays for most German cities. The main research focus of the work package is to select data and methods that support the retrieval of surface parameters that (1) can be repeatedly and flexibly generated for German cities and (2) are compliant with the thematic definitions and data formats required by the new UCM.
