GEONGEON

NSF Large ITR project – collaborative effort GEON is creating an IT infrastructure to

“enable” interdisciplinary geoscience research for the entire community

Project started in October 1, 2002 (after three years of preparation) and will continue

until September 30, 2007


GEON’s Vision

• Enable new discoveries in the geosciences by utilizing an easy-to-use “integration environment” built using state-of-the-art information technology resources.

The end product is a system that :Enables new interdisciplinary research and encourages resource sharing Stores and seamlessly integrates distributed data sets, software, and toolsAllows users to make searches to discover data and information

not only by name, but also by concepts.Provides high-end computational resourcesProvides a customizable analysis and research environment (workflow)Is a rich resource for teachers and learners

GEON Cyberinfrastructure Principles

• An equal partnership • IT works in close conjunction with science

• CI: Support the “day to day” conduct of science (e-science), in addition to “hero” computations

• The “two-tier” approach• Use best practices, including use of commercial tools and open

standards, where applicable…• …while developing advanced technology, and doing CS research

• Create shared “science infrastructure”• Integrated online databases, with advanced search and query engines• Online models, robust tools and applications

• Leverage from and work with other intersecting projects• Much commonality in the technologies, regardless of science

disciplines, e.g. BIRN, SEEK, and many others
