[Qgis-developer] Problems with gdal and hdf files

[Agustin Lobo]

Hi!

The gdal info of a multiband satellite image in hdf is reported by
gdal as "Size is 512, 512"
in contradiction with the size of the subdatasets. QGIS and R
(raster+rgdal) report an error at opening the file,
while envi and HDFLook can open it with no problem. I include the
gdalinfo output and the
info reported by HDFLook. Any help appreciated.
Thanks
Agus
