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)

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:

– 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
