HDF-EOS Workshop II Introduction

Candace Carlisle

Earth Science Data and Information Systems (ESDIS) Project

2HDF-EOS Workshop II

HDF-EOS

• 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

3HDF-EOS Workshop II

Purpose of this Workshop

• In-depth information about HDF and HDF-EOS for data

producers, user services, and tool developers

• Hands-on tutorials on HDF and HDF-EOS tools and utilities

• Hands-on tutorials on programming with HDF and HDF-EOS

Applications Programming Interfaces

• Individual consultation for individuals and teams

5HDF-EOS Workshop II

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

6HDF-EOS Workshop II

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
