  1. The SAFARI 2000 Data Distribution System Jeffrey L. Privette NASA’s Goddard Space Flight Center Many others from NASA, Wits, NDMC, ORNL 28 August 2001

  2. SAFARI 2000 Data Group • Ad hoc, voluntary • Objective: Develop and implement a system to: • Allow registered participants to access data in timely fashion • Protect rightsofdata collectors/providers and students • Including appropriate acknowledgement • Ensure complete SAFARI data archive is permanently housed in southern Africa • Participants • University of Witwatersrand • National Disaster Management Center • NASA’s Goddard Space Flight Center • Oak Ridge National Laboratory’s DAAC • University of Virginia

  3. “Registered SAFARI User” • Full participation is available to anyone who conducts relevant research and who agrees to the terms of the Data Policy • Registration via official SAFARI WWW site • SAFARI Steering Committee confirms that applicant meets above requirements • Approved registrant is provided with accounts on SAFARI data systems (Regional Data Centre and a Mercury host center) • Added to email “list server” (Newsletters, meeting information, invititations to publish, project information)

  4. Associated Data Centers Participant Data Archives Associated Data Centers Associated Data Centers Associated Data Centers Associated Data Centers Data System Components • ORNL DAAC • Mercury Metadata Editor Host • Mercury Host • NASA’s GSFC • Remote Sensing DataAcquisition • CD-ROM Production • Regional Data Centre • (National Disaster Management Centre) • Participant Registration • Mercury Metadata Editor Host • Permanent Archive

  5. Regional Data Centre (RDC) • Core of SAFARI Data System • Cooperative effort of the University of the Witwatersrand and the National Disaster Management Centre • NDMV provides hardware and software infrastructure to host and distribute data • Wits provides research input, strategic guidance and management assistance

  6. RDC Support of SAFARI • Host official SAFARI 2000 WWW site • Up-to-date project information • Downloadable software tools • Provide participant registration system • Host Mercury Metadata Editor • Host remote sensing data sets • NASA’s EOS Terra, Aircraft, etc. • Final repository for all SAFARI data

  7. RDC Resources • Hardware • Main web application server • IBM 4xPentium III 750 MHz, 5x18 GB HDD RAID, 750 MB RAM, Windows NT • Database server • Compaq Pro-Liant 5500, 2x Pentium III 650 MHz, 4x18GB HDD RAID, 780 MB RAM, with HP Intelligent RAID Rack 1.3 TB HDD system, Windows NT • GIS server • Compaq Pro-Liant 5500, 2x pentium III • 650 MHz, 4x18GB HDD RAID, 780 MB RAM, Windows NT • Maths / Statistical server, Compaq Pro-Liant 5500, • 2x pentium III 650 MHz, 4x18GB HDD RAID, 780 MB RAM, • Red Hat Linux 6.2 (7.1) • E-mail server, Compaq Pro-Liant 5500, pentium III • 200 MHz, 2x18GB HDD, 512 MB RAM • Personal Computers (6)

  9. ORNL DAAC… What’s That? • Oak Ridge National Laboratory’s (ORNL)Distributed Active Archive Center (DAAC) • Located in Oak Ridge, Tennessee (near Knoxville) • 1 of 7 DAACs created in the U.S. to provide data management for NASA’s Earth Observing System (EOS) • ORNL DAAC’s Focus: Biogeochemical Cycles • Provides strong support of the EOS Validation Program and major field campaigns (e.g., SAFARI, LBA)

  10. ORNL DAAC Support of SAFARI • Support Mercury Metadata Editor • Software to allow easy metadata submission • Internet online and “standalone” MELite • Host Mercury to allow SAFARI participants to search and access data • Harvests metadata from RDC and ORNL to create comprehensive SAFARI data catalog • Single best starting point to find any/all SAFARI data • Ground, aircraft, satellite, climatological, historical • Provides information and pointer (URL, name/email) for each data set

  11. Mercury Overview 1. 2. Data provider uses Metadata Editor to create file containing general information and links to the data and documentation ORNL Mercury collects the metadata file and adds to SAFARI Catalog SAFARI Metadata Catalog Data Provider Data and documentation 4. 5. User links to dataprovider’s server Data and documentation are downloaded directly from data provider 3. Participants query the Catalog and retrieve full metadata, including WWW links to data provider Participant

  12. Mercury System Investigator Data Site Internet Connection Courier / Air Mail Mercury Data Pathways

  13. 1. Fielded Search (choose from list of parameters, persons, etc.) 2. Spatial Search 3. Temporal Search

  15. NASA’s GSFC Support of SAFARI • Edit SAFARI Newsletter • Create and publish CD-ROMs • Stream MODLAND Product subsets to RDC in real-time • Manage requests for tasked NASA satellite data • e.g., Landsat 7, IKONOS

  16. “Associated Data Centers”The Landsat 7 Example Request NASA’s GSFC SAFARI Team (Maryland) SAFARI 2000 Participant Task Landsat 7 Science Team/ EROS Data Center (South Dakota) Acquire Archive/ Distribute

  17. “Associated Data Centers”The Landsat 7 Example Request NASA’s GSFC SAFARI Team (Maryland) SAFARI 2000 Participant Task Landsat 7 Science Team/ EROS Data Center (South Dakota) Acquire Archive/ Distribute TRFIC Data Center (Michigan State Univ.)

  21. SAFARI 2000 CD-ROM SeriesSiavonga: Volume 1 Release Party! CD-ROM Architect: Dave Landis, NASA’s GSFC

  22. The CD-ROM's HTML Interface • Uses an HTML/Web-browser interface that works the same on all computers (Windows, UNIX, Macintosh) • Allows access to data, documentation, and WWW links to additional resources. • Can automatically copy and decompress the image files from the CD-ROMs to the user’s hard drive • Help available through on-disc tutorials

  23. Data Contents of Volume 1 • Stratification by data type and volume • Hydrology Data (5 data sets) -- 2 megs • Land Cover Data (5 data sets) -- 32 megs • Meteorological Data (4 data sets) -- 30 megs • Satellite Images (6 data sets) -- 860 megs • Vegetation & Soils Data (4 data sets) -- 0.5 megs • Documents and Software -- 190 megs

  24. CD-ROM Satellite Images * AVHRR Parameters -- Day, LST, NDVI, PHI, R1, R2, TS, TV

  25. CD-ROM Documents and Software

  26. Next Step Involves You • Volume 1: first in a series • Satellite and climatological data were ready now • Forthcoming volume(s) will host participants’ data sets • Opportunity to branch out, collaborate, coauthor • Honor the Data Policy • CD-ROM includes many reminders of required acknowledgements • To be included: You must provide your metadata to the SAFARI Data Catalog! • Mercury Metadata Editor (online or standalone/email)
