The high-resolution digital surface model (DSM1, DOM1) of the watercourses Elbe and Lower Havel is based on the airborne laser scanning data, undertaken from 06 January 2022 to 18 March 2022 in the Elbe area and from 20 to 22 December 2021 in the Havel area.
\nIt was produced and published by Germany’s Federal Institute of Hydrology (BfG), on behalf of the River Basin Community Elbe (RBC Elbe, FGG Elbe). The work was supported by the German Federal Waterways and Shipping Administration (WSV) and the surveying offices and water management administrations of six German states - Saxony, Saxony-Anhalt, Brandenburg, Lower Saxony, Mecklenburg-Vorpommern and Schleswig-Holstein. Recent homogeneous geotopographic data of the Elbe watercourse and its historical floodplain are required for a number of applications in the fields of water management, hydraulic engineering and ecology.
\nThe data cover both the area around the inland water stretches of the Elbe from the Czech-German border to the village of Zollenspieker (part of the city of Hamburg) and the Lower Havel waterway from the town of Rathenow to its confluence with the Elbe. Since the dataset has a large coverage of 4,043 km², it is split into 62 sections. They were either labelled *HW in case of flood relevant areas (in German: “hochwasser-relevante Gebiete”) or *AU in case of historical floodplains (in German: “Altauengebiete”). Financing was divided according to these categories: In the HW areas, the project was co-funded by BfG, the WSV and the federal states, while in the AU areas, BfG covered all project costs.
\nFor each section we provide hillshade (*HS) and height maps (*NHN).
\nThe data are available as GeoTIFF-files (resolution 1 meter);
\nCoordinate reference frame: ETRS89.DREF91.R16;
\nCoordinate projection: UTM Zone 33N;
\nEPSG-Code: 25833;
\nHeight reference system: DHHN2016, national vertical reference frame in Germany (2022).
\n\n
Please note: the data in the Elbe-km 0-411 is identical in version 1 compared to version 2.
