Tab 1: Basic data of the dataset

Processed with timestamp January 2017. The metadata for every processed tile of this timestamp could be downloaded here.

There is also an WFS available: https://www.wcs.nrw.de/geobasis/wcs_nw_dgm

Be aware that the no data value in the exceeded border regions could be '0' or '9999'. In this case, a gdal calculation was applied:

gdal_calc -A input.tif --outfile= output.tif --calc="A*(A!=9999)"

It is not possible to use gdalwarp with multiple source null values. In this example it is assumed that the null values of the input tiff are 0 and 9999. If the condition A!=9999 is false the value zero will be applied and the new pixel value is zero.
