Major Development & Fixes since last meeting 14
Recent Major Development/Fixes 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_in. FOV | acos(cp (*) ·) -À/2 | < r. Ang. CB 15
Recent Major Development/Fixes HDF-EOS 2: – 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 16
Recent Major Development/Fixes – Segfault in creating swath when HDF files opened in read-only mode – Segfault in EHinquire function because of a VGroup with class "CDF 0. 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) – GDrs 2 ll should fail for any projection other than BCEA 17
Recent Major Development/Fixes HDF-EOS 5: – 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 18
Recent Major Development/Fixes 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 HDF 5 fillvalue and chunking info display – Bug fixes for saving HDF-EOS 5 files after modification 19
Recent Major Development/Fixes 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 20
Recent Major Development/Fixes – Stand-alone HEG GUI fixes for subset area selection for some products such as AMSR_E Sea. Ice 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 21
Recent Major Development/Fixes – 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 Sea. Ice products 22
Future Plans 23
Future Plans TOOLKIT/HDF-EOS: • Update of DEM Tools for new 500 m DEM data (Dean Gesch, U. S. Geological Survey) • XML Metadata reading in TOOLKIT • Support for new versions of HDF 4 - HDF 5 • Update of DEM land-sea mask (last Global land water mask created is at 250 m spatial resolution and was released Aug. 2009 ) • Auto Configuration for TOOLKIT • Support (or improvements) for 64 -bit platforms (C++) • Validation tool for HDF-EOS 5 files • Fix for reported bugs since the previous release 24
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-EOS 5 – Add World Coast Line map to HDFView Plug-in – Adding some HEG capabilities (Geotif output, projection conversion, resampling, etc) 25
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 Standalone GUI – Support HEG in MAC Intel – Resolve reported bugs or requests from DAACs/Users 26
