Höhenlinien Wuppertal 2015

The data series ‘Wuppertal 2015 altitude lines’ contains 6 elevation line records in the German Hauptthöhennetz 2016 (DHHN2016) with different equidae distances (1 m, 5 m, 10 m, 20 m, 50 m and 100 m) each in 2 forms with and without exemption on the buildings of the cadastral register. Each of these 12 data sets is held in 5 different data formats and coordinates. All data sets are based on the DGM1 digital terrain model provided by Geobasis NRW with the predominant data base 2015 (stands 2012 and 2017 in some northern and eastern peripheral areas of the Wuppertaler urban area). DGM1 is a regular point grid produced by airplane based laser scanning (lidar) with a mesh size of 1 m and an altitude accuracy of ± 2 dm. All the altitude lines were produced using ArcGIS 10.6 and the ArcGIS Spatial Analyst extension by interpolation in DGM1, without taking into account additional terrain edges. Beyond the standard behaviour of the “surface — contour line” tool available in the Spatial Analyst, there was no explicit further smoothing of the curvature of the altitude lines. The datasets from this series will not be continued. Following an update of the DGM1, the Wuppertal altitude is recalculated under other product names. All series datasets are available under an open data licence (CC BY 4.0).
