Package ucar.nc2.iosp.hdf4

Class HdfEos

java.lang.Object

ucar.nc2.iosp.hdf4.HdfEos

public class HdfEos
extends Object

Parse structural metadata from HDF-EOS. This allows us to use shared dimensions, identify Coordinate Axes, and the FeatureType.

from HDF-EOS.status.ppt:

 HDF-EOS is format for EOS  Standard Products
 

 
Landsat 7 (ETM+)
 
Terra (CERES, MISR, MODIS, ASTER, MOPITT)
 
Meteor-3M (SAGE III)
 
Aqua (AIRS, AMSU-A, AMSR-E, CERES, MODIS)
 
Aura(MLS, TES, HIRDLS, OMI
 
 HDF is used by other EOS missions
 

 
OrbView 2 (SeaWIFS)
 
TRMM (CERES, VIRS, TMI, PR)
 
Quickscat (SeaWinds)
 
EO-1 (Hyperion, ALI)
 
ICESat (GLAS)

Method Detail

amendFromODL

public static boolean amendFromODL(NetcdfFile ncfile,
                                   Group eosGroup)
                            throws IOException

Amend the given NetcdfFile with metadata from HDF-EOS structMetadata. All Variables named StructMetadata.n, where n= 1, 2, 3 ... are read in and their contents concatenated to make the structMetadata String.

Parameters:

ncfile - Amend this file

eosGroup - the group containing variables named StructMetadata.*

Returns:

true if HDF-EOS info was found

Throws:

IOException - on read error

getEosInfo

public static boolean getEosInfo(NetcdfFile ncfile,
                                 Group eosGroup,
                                 Formatter f)
