GDAL Library Loader configuration

It is possible to configure the GDAL library loader to load one of the installed GDAL distribution from the operating system or the internal GDAL distribution within SNAP (version 3.2.1).


The internal GDAL distribution is used when no GDAL distribution is installed on the operating system or when the installed version is not compatible. If the first option is selected and a GDAL distribution is installed on the operating system, SNAP will not load it until the second option is selected.
