This workshop provides an in-depth introduction to HDF and HDF-EOS, focusing on their relevance for Earth science data producers, user services, and tool developers. Attendees will engage in hands-on tutorials covering programming with HDF and HDF-EOS APIs, alongside consultations with experts. HDF-EOS serves as a baseline data format for efficient distribution and archiving of EOS data, ensuring portability and metadata organization. With anticipated growth in user communities, this workshop addresses emerging needs in data tools and analytics for diverse stakeholders.

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