HEG

• Utility to converts EOSDIS data from
• HDF-EOS2 to GeoTIFF formats.
• Versions Available
• Stand-alone A downloadable desktop version
• Data Pool Access through NASA archive online
  storage

3
HEG Functionality

• Conversion
• HDF-EOS (Swath or Grid ) to a single-band or
  multi-band GeoTIFFs
• HDF-EOS Swath to HDF-EOS Grid or Swath
• HDF-EOS Swath or Grid to generic Binary (with
  metadata file)
• Subsetting (spatial, field, band)

4
HEG Functionality

• Stitching (mosaicing) subsetting Reprojecting
• Reprojection ( to UTM, PS, TM, STP, LCC, LAMAZ,
  GEO, SIN, Albers, CEA)
• Subsampling (Subsample stacks)
• Running from Command Line (batch jobs)
• or with Java-based GUI

5
HEG Functionality

• Metadata preservation/creation.
• Currently supports
• MODIS, MISR, ASTER, AIRS, AMSR-E products on
  TERRA and AQUA (gt115 products),
• Operable on Sun, SGI, Win, Linux, MAC

6
HEG Functionality

• Integrated into ECS Data Pool
• Reduces the transfer time of HDF-EOS data sets
  (if subset is requested)
• Provides the end-user with the exact file
  required by their application
• User Interface
• Portable, written in Java.
• Not dependent on COTS (eg. IDL).

HDFView Plug-in

• HDFView
• A Java-based browser from THG for
• HDF4 and HDF5 based data.
• HDF-EOS plug-in
• Extends HDFView
• to browse HDF-EOS data in both versions (2 5).
• Is a plug-in module
• does not change THG HDFView functionality
• identical look and feel
• when displaying HDF and HDF-EOS objects
• access to complete breakdown of HDF-EOS objects.
  e.g. grid info, projection info, dims,
  datafields, and attributes
