Page 2 TOOLKIT / HDF-EOS Support Maintenance support is funded on EMD to EED Bridge (EEB) contract through Dec 2010 Support will continue with EOSDIS Evolution & Development (EED) award in 2010 Current support (One full-time developer) :  HDF-EOS2 & 5  SDP/MTD Toolkit  HDF-EOS plug-in for HDFView  HDF-EOS2 to GeoTIFF Converter (HEG)  Other Toolkit/HDF-EOS related software  Toolkit/HDF-EOS/HEG helpdesk  Related web sites maintenance

Page 3 ECS Support of HDF-EOS Both HDF4 and HDF5 based flavors of HDF-EOS are part of ECS baseline. OS’s: Solaris (9, 10), Linux ( 32 and 64-bit ), Mac OS X (Power PC and Mac Intel), Windows XP ( MTD Toolkit, HDF-EOS2 & 5, HEG, HDFView ) Added full Cygwin support in July 2009 release Compilers: Fortran 77/90 & g77/pgf90, C, C++, gcc, g++, gfortran (Mac Intel)

Page 6 Software/Tools in detail What are : TOOLKIT, HDF-EOS ?

Page 7 Toolkit Science Data Production (SDP) Toolkit : collection of tools used by - Science software developers who produce code to process instrument data. - HDF-EOS users who need to Access metadata in HDF-EOS files Perform Time/Date conversion Access Digital Elevation Model Data Access Ancillary Data, such as Digital Chart of the World database (DCW), Olson World Ecosystem files, DEM data files, etc.

Page 8 Toolkit (cont.) Tools provided in SDP Toolkit: - AA(Ancillary Data Access) - CBP(CELESTIAL Body Position) - CSC(Coordinate System Conversion) - CUC(Constant and Unit Conversions) - DEM(Digital Elevation Model Access) - EPH(Ephemeris Data Access) - GCT(Geo Coordinate Transformation) - IO(Input Output (File I/O)) - MEM(Memory Management) - MET(Metadata Access) - PC(Process Control) - SMF(Status Message File (Error/Status)) - TD(Time and Date Conversion)

Page 10HDF-EOS HDF-EOS is an extension to HDF which standardizes storage of and access to common Earth Sciences data structures – By providing a single interface to data structures common to earth science – By providing a container for EOS inventory, archive and product specific metadata – By establishing a consistent relationship between geolocation and science data.

Page 11 HDF-EOS 2 HDF4 - based, storage format for EOS standard products. Used operationally by MODIS, MISR, ASTER, Landsat, AIRS and other EOS instruments Support for Grid/Point/Swath structures

Page 12 HDF-EOS 5 Based on HDF5, a complete rewrite of HDF-EOS2 with a different user interface. – Used operationally by EOS Aura instruments Designed to ‘resemble’ HDF-EOS 2 to the maximum extent possible. – Supports same data structures (and more) – Added prefix ‘HE5_’ to HDF-EOS 2 functions
