Hi Romeo,
it seems that the inner GeoKey tags declare a projected CRS (Setting
GTModelTypeGeoKey = 1 = ModelTypeProjected).
However, there is neither a ProjectedCSTypeGeoKey (containing a well known
Projection code) nor a ProjCoordTransGeoKey / PCSCitationGeoKey which are
needed to handle a user-defined projected CRS. Therefore, the GeoTiff reader
has no way to know how to handle the user-defined Projection.
The only additional GeoKey Tag I have found on that file is the
GTCitationKey which referes to a "MTOTiff2GEOTiff" text.
Therefore I guess that this GeoTiff have been generated by some custom
script but I have no knowledge about how this script handles/write
CoordinateReferenceSystem information.
Do you have more info on this?
Regards,
Daniele
