Hi Anna,
a GeoTiff can be not georeferenced (has a grid to world transformation but
not a coordinate reference system),
a non geotiff file can be georeferenced instead (e.g arcgrid, netcdf, ecw,
and so on).
Instead:
* grab the format
* if format is not null, grab the reader (format will be null if we don't
have a reader for the file)
* from the reader, call getCoordinateReferenceSystem(), if this object is
null or it's a DefaultEngineeringCRS (a CRS for non georeferenced data)
then it's not georeferenced, otherwise it is.
This logic is still a bit over-simplified, it's based on the assumption
that you cannot get other types of CRS out of a grid coverage reader, like
a temporal or a vertical crs, nor a compuound one representing full 3D
data... but yeah, in the common cases it should work.
Hope this helps
Cheers
Andrea
