HDF-EOS to GeoTIFF Conversion Tool & HDF-EOS Plug-in for HDFView

  1. 1. HDF-EOS to GeoTIFF Conversion Tool & HDF-EOS Plug-in for HDFView Abe Taaheri, Raytheon IIS HDF & HDF-EOS Workshop XV Riverdale, MD April 17, 2012 Page 1
  2. 2. Page 2
  3. 3. 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 Page 3
  4. 4. 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) Page 4
  5. 5. 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 Page 5
  6. 6. HEG 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 Page 6
  7. 7. 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). Page 7
  8. 8. Examples (MISR) Mt. Etna Eruption: MISR L1B Stitched Blocks Page 8
  9. 9. Examples (MODIS) 2004 Hurricane Francis, MODIS MOD021KM, Multi-Band GeoTIFF, 3 bands: EV_1KM_RefSB, Bands 1,2,5 Page 9
  10. 10. Examples (ASTER) AST_L1B, 2003 California Fires Geo. projection, Multi-Band GeoTIFF (3 bands): Visible Near Infrared (VNIR) ….. and Subsetted Two Swaths Stitched ….. Page 10

  12. 12. 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 Page 12
  13. 13. HDFView Plug-in • Some features in the Plug-in Page 13
  14. 14. Swath, Grid, and Point Objects Plug-in file treeview Swath/Grid Lat/Lon display 14 Page 14
  15. 15. HE2 to HE5 Conversion One click to convert HE2 to HE5 file format 15 Page 15
  16. 16. AMSR-E Swath Getting Image of selected pixels in a table Getting lat/lon for a selected pixel in a table 16 Page 16
  17. 17. AMSR-E and OMI Point objects HE2 Point Object HE5 Point Object 17 Page 17
