[Gdal-dev] translating HDF4 to netCDF, HDF in --formats, but translate says "unsupported"

[Edward Fialkowski]

Hey List, trying to gdal_translate an HDF4 file to netCDF.

  HDF4 (ro): Hierarchical Data Format Release 4
  HDF4Image (rw+): HDF4 Dataset

shows up in --formats, but...

[edfialk at niceguy apps]$ ./gdal_translate -of netCDF no2track20070909.hdf
no2track20070909.nc
ERROR 4: `no2track20070909.hdf' not recognised as a supported file format.

GDALOpen failed - 4
`no2track20070909.hdf' not recognised as a supported file format.


I'm pretty sure it's hdf4 too, since hdfls reports:
[edfialk at niceguy bin]$ ./hdfls no2track20070910.hdf
no2track20070910.hdf:

so...gdal does have HDF4 as rw, the file is not HDF5 (hd5ls doesn't open
it)...anyone have any ideas?

Thanks!
