3. NSF Meeting on Cyberinfrastructure for Surficial Processes, Jan.18-19, 2006 Slide 3 GEON Background See website: www.geongrid.org, and portalwww.geongrid.org Began as a collaboration among ~15 institutions Goals Provide a Cyberinfrastructure-based Interpretive Environment for Earth Science research, e.g. for data acquired in EarthScope Support for data discovery A platform for data integration Train students and geoscience researchers in state-of-the-art and advanced IT concepts, i.e. technical aspects of geoinformatics Two-Tier approach Develop working systems, while also doing research and building advanced prototypes The focus this year is on registering content and tools at portal and providing a number of “reference” datasets The end goal is to provide science infrastructure. Support for both “hosted” and “non-hosted” data

22. NSF Meeting on Cyberinfrastructure for Surficial Processes, Jan.18-19, 2006 Slide 22 Data Registration: GEONsearch Choose a filetype Choose subject (from a “base” ontology) Choose location (from a gazetteer Webservice) Choose a time (numeric range or from a time ontology Webservice) Choose concepts from ontologies www.geongrid.org

24. NSF Meeting on Cyberinfrastructure for Surficial Processes, Jan.18-19, 2006 Slide 24 The 1-2-3 of GEON Data Registration 1.Register dataset, tool to index terms Allows users to more easily discover relevant resources 2.Register dataset “schema” to ontology E.g. Age_MA  Geologic Age Could be relational dbms, shapefile, Excel, netCDF, … Allows discovery of datasets that have information of interest, e.g. “all datasets that have velocity data” 3.Register data values to ontology E.g. “Jur”  Jurrasic Age from Geologic Age ontology Allows advanced data integration, e.g. integrate Paleobiology data with Paleostrat, or Neptune, Janus, etc. Prerequisite: ontologies need to be defined (by community), represented in OWL, and registered

31. NSF Meeting on Cyberinfrastructure for Surficial Processes, Jan.18-19, 2006 Slide 31 Opportunities Leverage CI from existing projects in same or even different disciplines Adopt a service-oriented architecture (SOA) i.e. standardize on Web service interfaces for tools, applications, and data E.g. Web Mapping Services for map image services, and WFS, WCS, and other standards, e.g for accessing geologic maps, gravity data, sensor data, … Need to deal with.NET and Java compatibility Develop centralized community services, e.g. for LIDAR processing Develop community standards for knowledge representation Schemas, controlled vocabularies, ontologies. Choose common representation system, e.g. OWL Organize community meetings, workshops, conferences Develop “Meta-workflow” frameworks Support inter-operation among different scientific workflow systems There may be an opportunity to work through a proposed new GSA Division on Geoinformatics and AGU working group on IT Geoinformatics 2006.
