1 HDF-EOS Workshop II HDF-EOS Workshop II Introduction Candace Carlisle Earth Science Data and Information Systems (ESDIS) Project

2 HDF-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

3 HDF-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

4 HDF-EOS Workshop II Workshop Sponsors Workshop Committee Ben Kobler, NASA Candace Carlisle, NASA Dan Marinelli, NASA John Berbert, NASA Doug Ilg, RITSS (formerly STX) George Schwenke, RITSS (formerly STX) Mike Folk, NCSA, University of Illinois Thanks to the ECS team for providing Facility Speakers Experts

5 HDF-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

6 HDF-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
