Wuppertal ATOM Feed Height Lines 2015
Description
The ATOM Feed Download Service for the Wuppertal Height Lines data series as of 2015 provides 6 height line datasets in the Deutsche Haupthöhennetz 2016 (DHHN2016) with different equidistances (1 m, 5 m, 10 m, 20 m, 50 m and 100 m), each in 2 versions with and without exemption on the buildings of the real estate cadastre. Each of these 12 data sets is kept in 5 different expressions regarding data format and coordinate system. All data sets are based on the digital terrain model DGM1 provided by Geobasis NRW with the predominant data level in 2015 (stands 2012 and 2017 in some northern and eastern peripheral areas of Wuppertal’s urban area). The DGM1 is a regular point grid generated by aircraft-assisted laser scanning (Lidar) with a mesh width of 1 m and a height accuracy of a single point of ± 2 dm. All vertical lines were created with ArcGIS 10.6 and the ArcGIS Spatial Analyst extension by interpolation in the DGM1 without taking into account additional ground breaking edges. Beyond the standard behavior of the “surface contour line” tool available in the Spatial Analyst, there was no explicit further smoothing of the curvature of the vertical lines. The records from this series are not continued. After an update of the DGM1, the Wuppertal height lines are newly derived under other product names. All data sets provided by the download service are subject to an open data license (CC BY 4.0).
