The Geosciences Network (GEON) (Cyberinfrastructure in Action) An Example of Democratizing Science G. Randy Keller - University of Oklahoma
Some CI Principles • Use state-of-the-art IT to support the “day-to-day” conduct of science (e-science), not just “heroic” computations • Develop advanced IT where needed • An environment based on Web/Grid services and other distributed technologies • The “two-tier” approach • Use best practices, including commercial tools, • Develop advanced, open source technology while conducting CS research • An equal partnership • IT works in close conjunction with science, to create CI (i.e. the best practices, data sharing frameworks, and useful and usable capabilities and tools) • Shared effort • Create shared “science infrastructure” • Integrated online databases with advanced search engines • Online models, robust tools and applications, etc. • Leverage from other intersecting projects • Much commonality in technologies needed exists, regardless of the science disciplines • Constantly work towards eliminating (at least, minimizing) the “NIH” syndrome (Not Invented Here) • And, importantly, try not to reinvent what industry already knows how to do… • Technologies to bring remote resources together
Why Geoinformatics? It is too hard to find and work with data that already exist, and too much data is in effect lost. It is too hard to acquire or access software tools and make them work. We have too little access to modern IT tools that would accelerate scientific progress. The result is too little time for science! Also, a wide range of students, scientists and engineers, industry, policy makers, and the public should have access to data and usable software tools. To begin to remedy this situation, a number of geoscience groups are being supported by the National Science Foundation to develop the cyberinfrastructure neededto move us forward. www.geongrid.org

SomeThoughts About Data (sets, bases, systems) • The Geosciences are a discipline that is strongly data driven, and large data sets are often developed by researchers and government agencies and disseminated widely. • Geoscientists have a tradition of sharing of data, but being willing to share data if asked or even maintaining a website accomplishes little. Also we have few mechanisms to share the work that has been done when a third party cleans up, reorganizes or embellishes an existing database. • We waste a large amount of human capital in duplicative efforts and fall further behind by having no mechanism for existing databases to grow and evolve via community input. • The goal is for data to evolve into information and then into knowledge as quickly and effectively as possible. www.geongrid.org

GEON Project Overview • Close collaboration between geoscientists and IT to interlink databases and Grid-enable applications • “Deep” data modeling of 4D data • Situating 4D data in context—spatial, temporal, topic, process • Semantic integration of Geosciences data • Logic-based formalisms to represent knowledge and map between ontologies • Grid computing • Deploy a prototype GEONgrid: heterogeneous networks, compute nodes, storage capabilities. Enable sharing of data, tools, expertise. Specify and execute workflows • Interaction environments • Information visualization. Visualization of concept maps • Remote data visualization via high-speed networks • Augmented reality in the field
Technical Areas • GEONgrid • Deployment of a distributed data sharing and computing infrastructure, consisting of GEON “nodes”, which provide a interoperable software environment • Data integration • GIS Map Integration • Knowledge-based integration of WMS (Web Mapping Services) • Database Schema integration • Seamless access to different types of data systems, e.g OpenDAP • Knowledge Representation • Geo-Ontology development • “Wrapping” science tools and applications • As Web services… • Invoked using scientific workflow software, e.g. Kepler, …and • Executed on Grid computing platforms, via portals • Visualization • 2D, 2.5D, 3D, 4D • Common data models, frameworks (e.g. between geophysics and geology)
