  1. HDF-EOS Status, Related Tools and Issues Abe Taaheri, Raytheon IIS 2010 THG Briefing to ESDIS

  2. TOOLKIT / HDF-EOS Support • Maintenance support is funded on EODDIS Evolution & Development (EED) Bridge contract (EEB) through May 2010 - Support will continue on EED starting May 2010 • Current support • HDF-EOS 2 & 5 • SDP & MTD Toolkits • HDF-EOS2 to GeoTIFF Converter (HEG) • HDF-EOS plug-in for THG HDFView • Other Toolkit/HDF-EOS related software • Toolkit/HDF-EOS/HEG helpdesk

  3. ECS Support of HDF-EOS • Both HDF4 and HDF5 based flavors of HDF-EOS are part of ECS baseline. • OS’s:Solaris (10), Linux (32 & 64-bit, including IA64), Mac OS X (Power PC and Mac Intel), Cygwin, Windows XP (MTD Toolkit, HDF-EOS2 & 5, HEG, HDFView) • Compilers:Fortran 77/90 , g77/pgf90 C, C++, gcc, g++ Intel Fortran (SGI Altix), gfortran (Mac Intel)

  4. Downloadable Software • DAACs are supported with TOOLKIT/HDF-EOS & HEG deliveries during yearly DAAC releases or patch deliveries • Other users can download our software from • our tools’ web sites • directly from our ftp site (edhs1.gsfc.nasa.gov)

  5. Downloadable Software SDP Toolkit(Science Data Processing Tools) MTD Toolkit(Metadata, Time/ Date Tools) HDF-EOS2 (HDF4 based) HDF-EOS5(HDF5 based) heconvert (converts HDF4 - based Grid/Point/Swath structures to HDF-EOS 5 equivalents) DumpMetadata(Dump HDF-EOS metadata)

  6. Downloadable Applications HEG - GeoTIFF conversion - Spatial subsetting, Field Subsetting - reprojection - stitching, sub-sampling and more …. HDFView Plug-in, Java-based browser (HDF4, HDF5, HDF-EOS 2 and 5 access) HE5View*(HDF5 - based browser) EOSView*(HDF4 - based browser) *Dropped support for OS updates on July 2006

  7. Software Releases

  8. Software Releases SDP Toolkit/HDF-EOS: Last release – July 2009 TOOLKIT 5.2.16 HDF-EOS 2.16, HDF- EOS5.1.12 with HDF4.2r4, HDF5-1.8.3, Szip2.1 Next release – June 2010 TOOLKIT 5.2.17 HDF-EOS 2.17, HDF-EOS5.1.13 with new releases of HDF4 (2r5), 5 (1.8.4 patch 1)

  9. Software Releases MTD Toolkit: Last release – Dec 2006 Version 5.2.13 in-sync with SDP TOOLKIT 5.2.13 with HDF4.2r0, HDF5-1.6.3, Szip1.2 Next release – July 2010 Version 5.2.17 in-sync with SDP TOOLKIT 5.2.17 with new releases of HDF4 (2r5), 5 (1.8.4 patch 1)

  10. HEG (HDF-EOS2 to GeoTIFF Converter): Last release – Dec 2009 Version 2.10 Patch release Jan 2010 Next release – Aug 2010 Version 2.11 Software Releases

  11. Software Releases HDF-EOS Plug-in for HDFView: Last release – Sep 2008 Version 2.4 Next release – Apr 2010 For HDFView Version 2.6

  12. Software Releases HECONVERT(HDF-EOS2 to HDF-EOS5 Converter): Last releases – 2001, 2004No Versioning – Oct. 2008Version 2.0 DumpMetadata(ASCII Dump of HDF-EOS metadata) Last release Dec. 2008Version 1.0

  13. TOOLKIT: XML metadata writing capability for inventory metadata in SDP toolkit (MLS) ODL fix (WriteLable) for potential core dump while writing long input pointer metadata attributes (AIRS) Support TOOLKIT for CYGWIN pccheck utility fix for problems resulting with empty space at a line beginning in PCF file Recent Development/Fixes

  14. HDF-EOS5: Correcting wrong tiling and compression info in the structure metadata Use of unlimited dimension in HDF-EOS5 (Users Guide clarification) Correction of output attribute data types in attribute inquiry routine Fix for writing int8 data correctly to output hdf5 file with C calls. There was no such a problem with Fortran calls Recent Development/Fixes

  15. HDF-EOS2: Correction for internal compression method detection for the products that are compressed internally after the production, possibly using hrepack (structure metadata has no record of compression info) Fixed PTdeftimeperiod to return an error when stop time < start time Recent Development/Fixes

  16. HDF-EOS Plug-in for HDFView: Support for all features in HDFView2.6 Correction for displayed lat/lon in a swath around the international date line Bug fix for HDF5 fillvalue and chunking info display Bug fixes for saving HDF-EOS5 files after modification Recent Development/Fixes

  17. HEG: Added Product Support: AMSR-E Daily 25 Km Sea Ice AE_SI25 AMSR-E Daily land AE_Land3 MOD29E1D: MODIS/Terra Sea Ice Extent & IST Daily L3 Global 4km EASE-Grid Day, Version 4 Tested many new products and updated the list of Hegable MODIS, ASTER, AIRS, MISR, and AMSR-E products in HEG Users Guide and HEG web site Recent Development/Fixes

  18. Enhancement: Added a new projection, Cylindrical Equa Area (CEA), to support AMSR-E Daily Land product. Pixel resampling support for gridded data with No-Reprojection Outputting all fields in a file to a single HDF-EOS output when HDF-EOS output is requested. Setting of projection parameters for multiband geotiff only once in the GUI Recent Development/Fixes

  19. Bug fixes: Pixel size unit correction for consistency between conversion and stitch GUIs. Problem resolution with several products MOD43C3, MOD10CM, MOD29P1N, AE_RnGd, AE_Rain Correcting sphere radius written to outputs for MODIS SIN grids Resolving problems with band selection in stitch GUI with occasional core dump (runs that take long time to complete) in Datapool HEGserver Recent Development/Fixes

  20. Future Plans TOOLKIT/HDF-EOS: XML Metadata reading in TOOLKIT Support for new versions of HDF4 - HDF5 Update of DEM land-sea mask Auto Configuration for TOOLKIT Support (or improvements) for 64-bit platforms Validation tool for HDF-EOS5 files Fix for reported bugs

  21. Future Plans (cont.) HDF-EOS Plug-in for HDFView: More functionalities : Cut/paste objects, modify/delete attributes. Create new grid/swath Support Zonal Average object for HDF-EOS5 HEG: Performance improvement for Lambert Azimuthal Projection conversion Support HEG in MAC Intel Resolve reported bugs or requests from DAACs/Users
