HEG FunctionalityHEG Functionality
• Conversion:
– HDF-EOS (Swath or Grid ) to a single-band or multi-band GeoTIFF’s
– HDF-EOS Swath to HDF-EOS Grid or Swath
– HDF-EOS Swath or Grid to generic Binary (with metadata file)
• Subsetting (spatial, field, band)

HEG FunctionalityHEG 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

HEG FunctionalityHEG Functionality
• Metadata preservation/creation.
• Currently supports
MODIS, MISR, ASTER, AIRS, AMSR-E products on TERRA and AQUA
– more than 210 products
• Operable on Sun, SGI, Win, Linux, MAC

HEG FunctionalityHEG 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-inHDFView Plug-in
• HDFViewA Java-based browser from The HDF Group 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 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
