overview
Overview
  • Mercury and Metadata Editor available
  • SAFARI 2000 data available from Mercury (43 data sets)
    • Field data for Kalahari Transect
    • Point and Gridded Regional Data Sets
    • Links to Remote Sensing products
    • Site ancillary data available for Mongu and Skukuza
  • Access to Land Validation and Global data registered in other versions of Mercury
  • MODIS data for Mongu and Skukuza sites to be posted (Summer 2001)
  • Tools for evaluating Mercury use being developed
ornl daac s support to safari 2000
ORNL DAAC’s Support to SAFARI 2000
  • Use Mercury to make data readily available to the project team both in the United States and southern Africa
  • After the SAFARI 2000 project, to assist in preparing selected data for archive and distribution to the public

1.The data provider uses an editor provided

by ORNL to create a metadata file containing

links to the data and documentation

ORNL

Metadata

Index

2. Mercury harvests the

metadata and builds

an index

Data and

documentation

5. Data and documentation

are downloaded directly

from the data provider

4. User links to data

provider’s server

3. Users query the index, which

returns full metadata, including

links back to the data provider

Mercury Overview

Mercury is used to assist an investigator with documenting data and making these data available to others.

activities
Activities
  • Mercury Metadata Editor established at ORNL DAAC and at SAFARI 2K Data Center at South Africa
  • Metadata Editor Lite (MELite)
    • standalone editor that produces files to be uploaded to the on-line Metadata Editor (PC platforms)
    • developed by S2K Project (Dozie Ezigbalike), available for download from the S2K Web site at Pretoria
  • Mercury Search system established at ORNL
    • Mercury harvests metadata from ORNL and Pretoria

best practices for preparing ecological and ground based data sets to share and archive
Best Practices for Preparing Ecological and Ground-Based Data Sets to Share and Archive
  • Best Practices include:

1. Assign Descriptive File Names

2. Use Consistent and Stable File Formats

3. Define the Parameters

4. Use Consistent Data Organization

5. Perform Basic Quality Assurance

6. Assign Descriptive Data Set Titles

7. Provide Documentation

  • Provided this document to SAFARI 2000, EOS Land Validation, BigFoot, and LBA projects
  • Available in booklets and in Bulletin of ESA
  • http://www.daac.ornl.gov/DAAC/PI/bestprac.html
s2k data sets in mercury with data source
S2K Data Sets in Mercury(with data source)
  • 6 Field Data – (UVa, BU)
  • 12 AERONET, SHADOZ , MPL– (GSFC)
  • 2 Remote Sensing – (GSFC)
  • 13 Regional (Gridded) – (ORNL)
  • 4 Regional (Point) – (ORNL)
  • 6 Historical – (ORNL)
other data sets in mercury
Other Data Sets in Mercury
  • Provide access to related data sets on southern Africa
  • 11 EOS Land Validation data sets collected in southern Africa
  • 28 global data sets in the DAAC’s version of Mercury that have data in southern Africa
    • climate, soil, vegetation, land cover, land use history, hydrology

1. Fielded Search

(using picklists for

Project, Site PI,

Parameter, etc.)

slide15

2. Spatial Search

Use Gazetteer

to select Country

Or enter specific

coordinates

posting modis products for eos land validation
Posting MODIS Products for EOS Land Validation
  • ORNL will post 7 x 7 km cutouts for selected MODIS products for Mongu and Skukuza tower sites (Summer 2001)
    • Surface Temperature, Surface Reflectance, Vegetation Indices, fPAR & LAI, Photosynthesis, BRDF
    • Temporal composites (8-, 16, 32, or 90-day composites)
    • Obtained from MODIS Adaptive Processing System (MODAPS) at GSFC
    • In ASCII table format and UTM projection, to relate to field measurements
data concerns
Data Concerns
  • Data Availability: not all SAFARI 2000 data are being registered in Mercury
    • SAFARI 2000 Policy of encouraging data submittal within 12 months (except students)
    • EOS Validation 6-month Policy for data submittal
  • Data synthesis and integration requires sharing data
    • Encouragement from S2K Leaders and Program Managers to register data in Mercury
  • Metadata and Documentation: Provide guidance on formats, file organization, units of measure
    • “Best Practices for Preparing Data Sets”
