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