  1. HDF-EOS to GeoTIFF Conversion Tool & HDF-EOS Plug-in for HDFView Abe Taaheri, Raytheon IIS HDF & HDF-EOS Workshp XIII Riverdale, MD November 3, 2009

  2. 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 HEG

  3. HEG Functionality Conversion: HDF-EOS (Swath or Grid ) to a single-band or multi-band GeoTIFF’s HDF-EOS Swath toHDF-EOS GridorSwath 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 (>115 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).

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

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

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

  10. HDFView Plug-in HDFView AJava-based browserfrom 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 

  11. HDFView Plug-in Some features in the Plug-in 

  12. Swath, Grid, and Point Objects Plug-in file treeview Swath/Grid Lat/Lon display

  13. AMSR-E Swath One click to convert HE2 to HE5 file format

  14. AMSR-E Swath Getting Image of selected pixels in a table Getting lat/lon for a selected pixels in a table

  15. AMSR-E and OMI Point objects HE2 Point Object HE5 Point Object
