  1. HDF-EOS Status, Related Tools and Issues Abe Taaheri, Raytheon IIS The HDF Group Briefing to ESDIS April 5, 2011

  2. Overview • Support Overview • Downloadable Software • Software Releases • Major Development & Fixes since last meeting • Future Plans • User Support

  3. TOOLKIT / HDF-EOS Support • Maintenance support for TOOLKIT/HDF-EOS is funded on EOSDIS Evolution & Development (EED) contract - May 2010 through March 2015 • 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 • helpdesk for Toolkit/HDF-EOS/HEG

  4. 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, VISTA, 7 (MTD Toolkit, HDF-EOS2 & 5, HEG, HDFView) • Compilers:Fortran 77/90 , g77/pgf90 C, C++, gcc, g++ Intel Fortran (SGI Altix), gfortran (Mac Intel)

  5. 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 web sites • directly from our ftp site (edhs1.gsfc.nasa.gov)

  6. 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)

  7. 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

  8. Software Releases

  10. 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 – Aug. 2011 Version 5.2.18 in-sync with SDP TOOLKIT 5.2.18 with HDF4 (2r5), 5 (1.8.6)

  11. HEG (HDF-EOS2 to GeoTIFF Converter): Last release – Mar. 2011 Version 2.11 Next release – Mar. 2012 Version 2.12 Software Releases

  12. Software Releases HDF-EOS Plug-in for HDFView: Last release – Apr. 2010 Version 2.6 Next release – May 2011 Version 2.7 (HDFView 2.7 released in Feb 2011)

  13. Software Releases HECONVERT(HDF-EOS2 to HDF-EOS5 Converter): Last release – Oct. 2008Version 2.0 Next release (Attributes for Hybrid files + Dimension scales conversion) – May 2011Version 3.0 DumpMetadata(ASCII Dump of HDF-EOS metadata) Last release Dec. 2008Version 1.0

  14. Major Development & Fixes since last meeting

  15. TOOLKIT: XML metadata writing capability for inventory metadata in SDP toolkit (5.2.16 release). Added XML style sheet to new TOOLKIT distribution for metadata display with Internet Explorer and other browsers Fix for writing metadata into an HDF file when multiple HDF files are open libiconv delivery in tar files for Mac and Cygwin Fix for setting correct endianness flag in linux for eph tools (Fix is for MOPITT eph files reading) Correction in PGS_CBP_body_inFOV | acos(cp (*) ·) -À/2 | < rAngCB Recent Major Development/Fixes

  16. HDF-EOS2: Added Dimension scales for Swath and Grid Fix for: Subsetting with GDdefboxregion results in an extra row and/or column in linux (round-off problem) Inconsistency in dimensions between real dims and the values in the structure metadata Problem on setting other compressions for swath and grid when disabling szip compression Recent Major Development/Fixes

  17. Segfault in creating swath when HDF files opened in read-only mode Segfault in EHinquire function because of a VGroup with class "CDF0.0” Segfault in GDapi (sincos redefinition problem) Segfault in sample test grid subsetter compinfo functions must return -1 only for errors (not for COMP_NONE) GDrs2ll should fail for any projection other than BCEA Recent Major Development/Fixes

  18. HDF-EOS5: Added Dimension scales to Swath, Grid, and Zonal Average fields Fix for problem in setting fillvalue; Fillvalue is only for the field defined right after setting fillvalue Recent Major Development/Fixes

  19. HDF-EOS Plug-in for HDFView: Support for all features in HDFView 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 Major Development/Fixes

  20. HEG: Enhancement / Bug Fixes: Performance improvement for conversion to Conical or Azimuthal projection Preserving input datum for output projection Better default values when user fails to enter some key projection parameters specifically when input grid is global and output projection LCC or LA Recent Major Development/Fixes

  21. Stand-alone HEG GUI fixes for subset area selection for some products such as AMSR_E SeaIce products Better handling of UTM outputs when user fails to enter appropriate UTM zone and/or subset area for Global input grids Windows VISTA and 7 testing/support Recent Major Development/Fixes

  22. Resolving problem with some output State Plane projection conversions when user fails to enter appropriate SP zone (leading 0 in some 3-digit SP zone codes in statezones.h) Modifying input default lat of +/- 90 for AE Ocean products when output projection is Mercator Correcting a problem offending input negative Earth Flattening value in AMSR_E SeaIce products Recent Major Development/Fixes

  23. Future Plans

  24. Future Plans TOOLKIT/HDF-EOS: Update of DEM Tools for new 500m DEM data (Dean Gesch, U.S. Geological Survey) XML Metadata reading in TOOLKIT Support for new versions of HDF4 - HDF5 Update of DEM land-sea mask (lastGlobal land water mask created is at 250m spatial resolution and was released Aug. 2009 ) Auto Configuration for TOOLKIT Support (or improvements) for 64-bit platforms (C++) Validation tool for HDF-EOS5 files Fix for reported bugs since the previous release

  25. 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 Add World Coast Line map to HDFView Plug-in Adding some HEG capabilities (Geotif output, projection conversion, resampling, etc)

  26. Future Plans (cont.) HEG: Performance improvement for all supported products (EED On-Demand-Data-Access Web Services) Support for fields with dimensions 5 or larger (MISR) Allowing HEG to open Parameter file with Stand-alone GUI Support HEG in MAC Intel Resolve reported bugs or requests from DAACs/Users
