[GRASSLIST:6142] r.in.gdal and HDF import

GRASS GRASS user

I'm sorry for being such a pain sending this question both to the winGRASS and the GRASS users list. I promise to improve in the future : )

Well, I'm trying to import sea surface temperature data obtained in the HDF-format from NOAA using grass6.0.cvs/cygwin running on Windows XP, but the following message appear:

ERROR 4: `198501h09ma-gdm.hdf' not recognised as a supported dataset name.

I’ve been through quite a few internet pages this weekend, searching for some way to get around this problem, but I’ve been unsuccessful so far : ( Is there anybody out there who knows how I could get around this problem :slight_smile:

Thanks in advance,

Torkild

Hi,

have a look at http://www.gdal.org/frmt_hdf4.html.

Use gdalinfo to list all multidimensional subdatasets from
the input HDF file.
Then choose the subdateset, which you'd like to import. You
should provide exactly the contents of the line marked
SUBDATASET_n_NAME to GDAL, including the HDF4_SDS: prefix
as
raster file to be imported.

like this:
HDF4_SDS:MODIS_L1B:GSUB1.A2001124.0855.003.200219309451.hdf:2

Hope this will help you,
Grit

Look at the r.in.aster script for a way to use gdalwarp within a grass
environment to read ASTER HDF files into GRASS and georeference them.
Something along the lines of what I did in this script should be relevant to
the NOAA data too.
