Hi Scott,
thank you for your reply! I just have executed the command you suggested me,
gdal-config --formats
and that's what I got:
gxf gtiff hfa aigrid aaigrid ceos ceos2 iso8211 xpm sdts raw dted mem
jdem envisat elas fit vrt usgsdem l1b nitf bmp pcidsk airsar rs2 ilwis

pds adrg coasp tsx terragen blx msgn wcs wms grib bsb jpeg2000 hdf5 hdf4
gif jpeg png netcdf pcraster rik
So, I guess that I have already built the jpeg2000 support. Any Suggestion?

I am not able to open grib2 files with GDAL. For example, in the attached
file
http://rapidshare.com/files/249911240/MPE_20090629_0900_M9_00.rar.html
I succeed in obtaining information about the file with GDALINFO command, but
I cannot convert it into a GTiff (using gdal_translate command). I obtain
the following message:
Input file size is 3712, 3712
0Segmentation fault
I know this file is not corrupted because I can open it with another
software. What am I doing wrong?
Hi Alberto,
GRIB2 files can be compressed using different encoding schemes, the
GDAL page here (http://www.gdal.org/frmt_grib.html) says
"There are several encoding schemes for raster data in GRIB format.
Most common ones should be supported including PNG encoding. JPEG2000
encoded GRIB files will generally be supported if GDAL is also built
with JPEG2000 support via one of the GDAL JPEG2000 drivers. The JasPer
library generally provides the best jpeg2000 support for the GRIB
driver."
It doesn't look like JPEG2000 support is built by default
(http://www.gdal.org/formats_list.html), so you might need to build
your own GDAL, if you want to read these files using GDAL. You could
start by checking whether your GDAL has been built with JPEG2000
support ('gdal-config --formats' on the command line).
An alternative to access the data is wgrib2
(http://www.cpc.ncep.noaa.gov/products/wesley/wgrib2/), which I've
used in the past to read the Meteosat precipitation product you're
dealing with.
Cheers,
Scott
