Re: GDAL package error message at install

Hi Philip,

Thanks for the information about 4.0.1. Have installed the updated
version and output of rasterinfo.m seems to be ok, mainly looking for
the projection information:

Just a test output, does this look like the correct output for a
geotiff, with mapping 1.2.1 installed:

Is there a way to just limit the output info to the projection information?

Thanks
