I ran gdalinfo on some HDF4 files and no subdataset shows up.
The data is available for download at this website: http://mirador.gsfc.nasa.gov/cgi-bin/mirador/presentNavigation.pl?tree=project&project=TRMM&dataGroup=Gridded&dataset=3B43:%20Monthly%200.25%20x%200.25%20degree%20merged%20TRMM%20and%20other%20sources%20estimates&version=006
I tried reading those some file on:
- ArcGIS 9.3
- ArcGIS 10 (RC)
They do identify the internal datasets but they cannot identify the reference system and the images they are flipped by 90' clockwise. But that is not due to rotation. I would guess. It is more like a misinterpretation of the dimension parameter, taking rows as columns and columns as rows. It looks like the documentation for that particular product is missing here: http://mirador.gsfc.nasa.gov/cgi-bin/mirador/servcoll.pl?helpmenuclass=inventory&SearchButton=Search%20GES-DISC
Does anybody has a clue?
BTW. There is a netCDF version of that data that also has some issues.
