[gdal-dev] Re: How to use gdalinfo for HDF- Windows

[Luisa Peña]

Hey Brent
I'm using ESA's GLOBCOVER data.In this case I'm trying to set a GRASS script
to run gdal directly.
I do:
gdalinfo C:\data\GL.hdf and I retrieve all basic information plus HDF's
layers

Driver: HDF4/Hierarchical Data Format Release 4
Files: c:\data\GL.hdf
Size is 512, 512
Coordinate System is `'
Metadata:
  HDFEOSVersion=HDFEOS_V2.12
Subdatasets:
  SUBDATASET_1_NAME=HDF4_EOS:EOS_GRID:"c:\data\GL.hdf":POSTEL:MEAN_1
  SUBDATASET_1_DESC=[1800x1800] MEAN_1 POSTEL (16-bit integer)
 SUBDATASET_2_NAME=HDF4_EOS:EOS_GRID:"c:\data\GL.hdf":POSTEL:MEAN_2
  SUBDATASET_2_DESC=[1800x1800] MEAN_2 POSTEL (16-bit integer)
  SUBDATASET_3_NAME=HDF4_EOS:EOS_GRID:"c:\data\GL.hdf":POSTEL:MEAN_3
  SUBDATASET_3_DESC=[1800x1800] MEAN_3 POSTEL (16-bit integer)
  SUBDATASET_4_NAME=HDF4_EOS:EOS_GRID:"c:\data\GL.hdf":POSTEL:MEAN_4
  SUBDATASET_4_DESC=[1800x1800] MEAN_4 POSTEL (16-bit integer)
  SUBDATASET_5_NAME=HDF4_EOS:EOS_GRID:"c:\data\GL.hdf":POSTEL:MEAN_5
(...)

then:
gdalinfo HDF4_EOS:EOS_GRID:"c:\data\GL.hdf":POSTEL:MEAN_1

I get:
ERROR 4: 'HDF4_EOS:EOS_GRID:c:\data\GL.hdf:POSTEL:MEAN_1'
does not exist in fyle system, and is not recognised as a supported dataset
name.
gdalinfo failed- unable to open
'HDF4_EOS:EOS_GRID:c:\data\GL.hdf:POSTEL:MEAN_1''
open GDAL Datasets:
1 N DriverIsNULL 512x512x0

But if I do:
 gdalinfo HDF4_EOS:EOS_GRID:":\data\GL.hdf":POSTEL:MEAN_1
it works (without the C from the driver)

The problem is that if I'm trying to to use data in D it does not work.
Any suggestions?
