2. Utility to convert EOSDIS data from HDF-EOS2 to GeoTIFF formats.
HEG
Utility to convert EOSDIS data from
HDF-EOS2 to GeoTIFF formats.
Versions Available:
Stand-alone: A downloadable desktop version
Data Pool: Access through NASA archive online storage 2

3. HEG 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) 3

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 4

5. HEG Functionality Metadata preservation/creation. Currently supports
MODIS, MISR, ASTER, AIRS, AMSR-E products on TERRA and AQUA
more than 115 products
Operable on Sun, SGI, Win, Linux, MAC 5

6. HEG Functionality Integrated into ECS Data Pool User Interface
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). 6

7. Examples (MISR)
Mt. Etna Eruption: MISR L1B Stitched Blocks 7

8. Examples (MODIS) 2004 Hurricane Francis, MODIS
MOD021KM, Multi-Band GeoTIFF, 3 bands: EV_1KM_RefSB, Bands 1,2,5 8

9. Examples (ASTER) AST_L1B, 2003 California Fires
Geo. projection, Multi-Band GeoTIFF (3 bands):
Visible Near Infrared (VNIR)
….. and Subsetted
Two Swaths Stitched ….. 9

10. HDFView Plug-in HDFView A 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  10
