GEON Cyberinfrastructure

• Funded by NSF IT Research program (~$11.5M)• Multi-institution collaboration between IT and

Earth Science researchers• GEON Cyberinfrastructure provides:

• Authenticated access to data and Web services• Registration of data sets, tools, and services with

metadata• Search for data, tools, and services, using ontologies• Scientific workflow environment• Data and map integration capability• Scientific data visualization and GIS mapping

Slide 5

Key Informatics Areas• Portals

• Authenticated, role-based access to cyber resources: data, tools, models, model outputs, collaboration spaces, …

• Data Integration• Search, discover and integrate data from heterogeneous information

sources (“mediation” and “semantic integration”)• Modeling and simulation environments based on “scientific

workflow” software• Users can “program” and steer computations at a higher level of

programming abstraction• Share models (not only data), and support generation and sharing of

provenance information• Geospatial information and Geographic Information Systems (GIS)

• Spatial statistics, spatiotemporal data mining• Visualization of 2D, 2.5D, 3D, 4D data, and multidimensional

information spaces

Slide 6

GEON Science Projects

• Paleo Integration Project• Integrated access to paleogeography, paleobiology,

geochronology databases and services

• LiDAR Integration Project• Development of a national framework for LiDAR data

management. Integration of LiDAR products with other geophysics datasets.

• Geophysics Integration Project• Integration of gravity and magnetic data with seismic

modeling programs, for developing models for crustal structure. Could include geodynamics models.

Slide 7

LiDAR Workflow

• Current implementation• 32-way IBM multiprocessor, 128GB, 8TB SAN• ~2TB point cloud data, ~6B rows in database• ~20TB orthophotos

• Migrating to…• 16-way Linux cluster, 64-bit Intel processors• Central warehouse + replicas for failover and

load balancing

• Provide national framework for• On-demand access & analysis of LiDAR and

other remote sensing data

Meeting in August with USGS EROS Data Center to make continental-scale datasets open to GEON and other user communities (NEON, hazards, …)

Collaboration with AIST, Japan on ASTER and other remote sensing datasets

Slide 8

International GEON (iGEON): India

• Collaboration with University of Hyderabad• Prof. K.V. Subbarao, Professor-in-Charge, Center for Earth and Space

Sciences• Prof. Arun Agarwal, Professor-in-Charge, Center for Modeling, Simulation,

and Design & Head, Department of Computer Science

• Conducted GEON Cyberinfrastructure Workshop, following PRAGMA meeting, Oct. 2005, Hyderabad

• iGEON-India recently funded as a Knowledge Networked R&D Center, by the Indo-US Science and Technology Forum• Deploy GEON Node at UofHyd and an India-based portal• Continue GEON Cyberinfrastructure workshops• Partner with Indian geoscience institutions, including:

• National Geophysical Research Institute, National Remote Sensing Agency, Indian National Center for Ocean Information Systems, Wadia Institute of Himalayan Geology, Birbal Sahni Institute of Paleo-Botany

Slide 9

International GEON (iGEON): Japan

• Collaboration with AIST, Tokyo• Dr. Satoshi Sekiguchi

• Initiating a GEOGrid in Japan. Inauguration in early October, 2006

• Will make various remote sensing data available using GEON technologies, and via GEON

Slide 10

Opportunities for iGEON-China

• Deploy GEON node in China• Share data sets from China

• From agencies as well as individual PI’s—by registering them into GEON

• Use iGEON-China as a way to bring together activities within China

• Share Geoscience tools and applications• Make tools and applications developed by Chinese

research community available as Web/Grid services for remote access

• Share Grid computing resources
