7. Software/Tools Brief description of TOOLKIT, HDF-EOS, And HDFView Plug-in

8. Toolkit Science Data Production (SDP) Toolkit : collection of tools used by - Science software developers who produce code to process instrument data. - HDF-EOS userswho 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.

9. Toolkit (cont.) Tools provided in SDPToolkit: - 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)

10. Toolkit (cont.) MTD Toolkit: a short version of SDP Toolkit Tools provided: MET(Metadata Access) TD (Time and Date Conversion) Also supported in windows

11. HDF-EOS HDF-EOS: 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.

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

13. HDF-EOS 5 • HDF5 - based, a complete rewrite ofHDF-EOS2with a different user interface. • Used operationally byEOS Aurainstrument teams • Designed to‘resemble’ HDF-EOS 2to the maximum extent possible. • Supports same data structures (and more: Zonal average) • Addedprefix ‘HE5_’ to HDF-EOS 2 functions to distinguish two libraries

14. HDFView Plug-in HDFView:A Java-based browser from The HDF Group for HDF4 and HDF5 based data. HDF-EOS plug-in Extends HDFView to browse HDF-EOS data in both versions. Is a plug-in module and does not change The HDFView functionality Have identical look and feel when displaying HDF and HDF-EOS objects Users can access a complete breakdown of HDF-EOS objects. e.g. grid info, projection info, dims, datafields, and attributes 

15. HEG • HEG • GeoTIFF conversion • Multi-band GeoTIFFs • Swath to Grid conversion • Spatial subsetting, Field Subsetting • Reprojection • Stitching, sub-sampling and more ….
