[Gdal-dev] gdal_translate of HDF : resulting GeoTiff file strange

[mattia]

Hey all,

I ran the following command on an HDF format:

$ gdal_translate HDF4_SDS:UNKNOWN:"AMOD021KM20061229043102.hdf":9
test_b9.tif

I hence get a geotiff file called test_b9.tif
I actually ran the command on all my 26 channels and got 26 different TIF
files.
I think that this should be the most important channel though, namely, it is
the :

  SUBDATASET_9_NAME=HDF4_SDS:UNKNOWN:"AMOD021KM20061229043102.hdf":8
  SUBDATASET_9_DESC=[16x3630x1354] EV_1KM_Emissive (16-bit unsigned integer)


If I now run gdalinfo I get:

rasdaman at mattia-desktop:~/FTPCHINA$ gdalinfo -nomd test_b8.tif

Isnt this a strange result?

What about the coordinate system?

I tried to merge all the tifs with gdalwarp, but had no success so far..

I'm pretty new to this field and in very high waters..

Any suggestions?


Thanks
