This document introduces an HDF-EOS workshop for data producers, users, and tool developers. HDF-EOS is the baseline standard data format for EOS data, based on HDF but adding features for EOS. The workshop aims to provide in-depth information about HDF and HDF-EOS through hands-on tutorials for tools, utilities, and programming. It is sponsored by NASA and the ECS team, and provides individual consultation. HDF-EOS supports a large community that will need various analysis tools, and resources like documentation, sample data, and experts are available to support the HDF-EOS format.

Baseline standard data format for distribution, production and archive
of EOS data
Selected based on evaluation of available formats and science data
needs
Based on National Center for Supercomputing Applications (NCSA)
Hierarchical Data Format
HDF-EOS adds EOS data features to HDF
– HDF-EOS developed by EOS Core System contracto
HDF-EOS provides
– Portability
– Self-description, allowing data to be read by generic tools
– Pre-organized metadata
NASA invests in improvements to HDF and HDF-EOS

5. HDF-EOS Vendor Opportunities
•
Large and growing community of EOSDIS users
– In 1996, there were over 20,000 distinct users of earth science data
that accessed NASA DAACs (“EOSDIS Version 0”)
– We expect rapid growth in the number of users with the launch of
EOS AM-1, Landsat 7, and Sage III
– EOSDIS data is widely available and free or inexpensive to obtain
• e.g. NASA may charge users for cost of media and shipping
– Expected user community includes
• Public sector (NASA, NOAA, USDA...)
• Scientific researchers
• Commercial users
• Education community
• International Partners

6. HDF-EOS Vendor Opportunities, Cont’d
•
EOSDIS users will need a broad spectrum of tools with these
capabilities:
– browsing
– viewing
– subsetting
– image analysis and enhancement
– mathematical and statistical analysis
– processing
– graphics
– animation
