100 m Height Lines Wuppertal 2015

The data set “100 m Height Lines Wuppertal 2015” contains elevation lines with an equidistance of 100 m for the entire city area of Wuppertal. There are 5 different types of data format and coordinate system. The data set is 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. The 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 record will not be continued. After an update of the DGM1, the Wuppertal height lines are newly derived under other product names. The dataset is available under an open data license (CC BY 4.0).
