7 Software/Tools
8
8 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.
9
9 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)
10
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
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
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
13 HDF-EOS 5 HDF5 - based, a complete rewrite of HDF-EOS2 with a different user interface. Used operationally by EOS Aura instrument teams Designed to ‘resemble’ HDF-EOS 2 to the maximum extent possible. Supports same data structures ( and more: Zonal average ) Added prefix ‘HE5_’ to HDF-EOS 2 functions to distinguish two libraries
14
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 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
15 HDFView Some features in the Plug-in
16
16 Swath, Grid, and Point Objects Plug-in file treeview Swath/Grid Lat/Lon display
17
17 HE2 To HE5 Conversion One click to convert HE2 to HE5 file format
18
18 AMSR-E Swath Getting Image of selected pixels in a table Getting lat/lon for a selected pixel in a table
19
19 AMSR-E and OMI Point objects HE2 Point Object HE5 Point Object

25 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) Recent Major Development/Fixes
26
26 HDF-EOS2: – Added Dimension scales for Swath and Grid Fix for: – Subsetting with GDdefboxregion which resulted 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 Recent Major Development/Fixes
27
27 – Segfault in creating swath when HDF files opened in read-only mode – Segfault in EHinquire function because of a VGroup with class "CDF0.0” – Segfault in GDapi (sincos redefinition problem) – Segfault in sample test grid subsetter – compinfo functions must return -1 only for errors (not for COMP_NONE) – GDrs2ll should fail for any projection other than BCEA Recent Major Development/Fixes

31
31 Future Plans Store info in structural metadata somewhere else Auto Configuration for TOOLKIT RPMs for HDF-EOS and Toolkit Validation tool for HDF-EOS5 files Fix for user/DAAC reported bugs
32
32 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-EOS5 – Add World Coast Line map to HDFView Plug-in
