      Thank you Andrew for that piece of information. I will pre-filter
      with gdalinfo and avoid loading tiles with only nodata values
      beforehand.<br>

              <div> Just to give the solution I found:<br>
                I use gdal_retile.py now for preparing tiles from my
                large GTiff files. Besides: Using a clean Ubuntu 20
                docker and install pdal works fine. pdal/pdal:2.2 also
                does, pdal/pdal:latest does not<br>
                <br>
                Thank you for everybody helping!<br>
                <br>
                This does however lead to another question:<br>
                is there a way to stop the execution of the writer in a
                pipeline where the first filtering stage has an empty
                result - no points? Or am I missing something. Please
                bare with me, I'm new to PDAL.<br>
