DumpMetadata(ASCII Dump of HDF-EOS metadata)

Last release

Dec. 2008Version 1.0


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)


pccheck utility fix for problems resulting with empty space at a line beginning in PCF file

Recent Development/Fixes


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


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

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


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


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
