Page 12 What is HDF-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 13 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 HDF4 and HDF-EOS 2 will be supported by THG/NASA for the fore-seeable future.

Page 14 HDF-EOS 5 Based on HDF5, a complete rewrite of HDF-EOS2 with a different user interface. – First released in – Format used by EOS Aura instruments Designed to ‘resemble’ HDF-EOS 2 to the maximum extent possible. – Supports same data structures – Added prefix ‘HE5_’ to HDF-EOS 2 functions.

Page 15 HDFView HDFView: A Java-based browser from THG for HDF4 and HDF5 – based data. HDF-EOS plug-in extends HDFView to browse HDF-EOS data in both versions. The extension is a plug-in module and does not change THG HDFView functionality. All copy, save, editing, image display, etc. for HDF4 and 5 objects remains.

Page 16 HDFView Identical look and feel when displaying HDF and HDF-EOS objects. Users can access a complete breakdown of HDF-EOS objects. e.g. grid information, projection info., dimensions, datafields, and attributes are displayed. Current Support: SUN, SGI, LINUX, Mac, WINDOWS platforms

Page 19 HEG: Utility that converts EOSDIS data from HDF-EOS format to common Geographical Information System (GIS)-compatible formats. Two versions available : – A downloadable desktop version – Access through NASA archive online storage (Data Pools) – Implemented also in some prototypes: ▪ Stand-alone Data Pool ▪ OGC ( Open Geospatial Consortium ) for Web Services Chaining ▪ DOWS (Deploy OGC Web Services) on the DAACs HDF-EOS to GeoTIFF Converter (HEG)

Page 20 HEG Functionality Conversion: – HDF-EOS (Swath or Grid ) to a single-band or multi-band GeoTIFF’s – HDF-EOS Swath to HDF-EOS Grid – HDF-EOS Swath or Grid to generic Binary – Metadata preservation/creation. – Allows file selection from users local storage

Page 21 HEG Functionality Subsetting ( spatial, field, band ) Stitching ( mosaicing ) + subsetting + Reprojecting Reprojection ( to UTM, PS, TM, STP, LCC, LAMAZ, GEO, SIN, Albers ) Subsampling ( Subsample stacks ) Running from Command Line (batch jobs) or with Java-based GUI

Page 22 HEG Functionality Currently supports MODIS, MISR, ASTER, AIRS and AMSR-E products on TERRA and AQUA (>110 products), Operable on Sun, SGI, Win, Linux, MAC Integrated into ECS Data Pool – Reduces the transfer time of HDF-EOS data sets (if subset is requested) – Provides the end-user with the exact file required by their application User Interface – Portable, written in Java. – Not dependent on COTS (eg. IDL).
