IT Approach
• Develop cyberinfrastructure to support the “day-to-day”
conduct of science (e-science), not just “hero”
computations
– Based on a Web/Grid services-based distributed environment
• Work closely with geoscientists to help create data
sharing frameworks, best practices, and useful and
usable capabilities and tools
• The “two-tier” approach
– Use best practices, including commercial tools,
– while developing advanced technology in open source, and
doing CS research
• Leverage from other intersecting projects

Other Intersecting Projects
• BIRN—Biomedical Informatics Research Network
– Baru, Papadopoulos, Gupta are in BIRN Leadership Team
– Leverage technology for portals, BIRN Mediator, workflow
– Learn from their release plan/schedule and software engineering activity
• SEEK—Science Environment for Ecological Knowledge
– Leverage schema registration technology (Ludaescher is co-PI)
• Southwest GeoNet
– User their .Net-based services. Provides an alternate Web services
environment
• DLESE—Digital Library for Earth System Education
– Use infrastructure developed for education in research applications
• OptIPuter
– Working with NASA GSFC to provide 1Gpbs link to UCSD/SIO. GSFC
will be node on GEON

Other Intersecting Projects…
• GRASP
– Run Grid benchmark probes along with Inca monitoring infrastructure in
GEONgrid (Baru is PI)
• NMI GRIDS Center
– Developing easy-to-use Grid security infrastructure for GEON, BIRN,
and UCSD Telescience
• TeraGrid
– GEON is a chosen application. In particular, hosting data and services
related to LiDAR data
• NLADR – National Laboratory for Advanced Data Research
– Joint activity between SDSC and NCSA
– GEON is a chose application to drive end-to-end data scenarios

Partnerships
• ESRI
– GEON node at Redlands
– Find ESRI resources through GEONsearch
– Publish GEON products in ArcWeb
• IBM
– Working with IBM Almaden on GMR (Grid Movement and Replication)
• HP
– Donated a cluster to power GEON portal.
– 9-node system. One node with 24GB memory and 20TB disk
• GSC
– Providing WMS server via WestGrid (Vancouver, BC)

Partnerships
• Geological Survey of Canada
– 1Gbps connection to WMS server in WestGrid
• NASA
– 1Gbps connection to NASA GSFC, SRTM and other imagery
and LiDAR data
• ESRI
– Grid service wrappers for ArcWeb Services
– Ability to publish GEON “products” using ArcWeb Services
• Chronos, CUAHSI, etc.
– Register resources so that they are searchable via GEONsearch
