<br>
Please make is easier for us to help you and provide a link to such raster<br>
file. It does not need to be your real, perhaps confidential data, a small<br>
extract is actually much better. Just take care that if shows all the issues<br>
that you wrote about. Meanwhile you can read<br>
<a href="https://trac.osgeo.org/gdal/wiki/rfc73_proj6_wkt2_srsbarn">https://trac.osgeo.org/gdal/wiki/rfc73_proj6_wkt2_srsbarn</a> and think if this<br>
change could explain some of your observations.<br>
