Well, I suppose that your local copy of the code use
GDALMD_ARE_OR_POINT unquoted...
as mentioned before, with and without.
I've tried a simplified version of your code and it works for me. Do
you use a recent enough version of GDAL ?
Yes. A svn revision after 1.11.
Note: for AREA_OR_POINT to be taken into account in GeoTiff, you need
to define both a geotransform and a SRS.
AHHHHHH. This changes the whole story. Some cases do not set a SRS. Is
there any fall-back SRS that I could use when no info is available to
create one?
Type, 'linear in unknown units'?
