Collaborations

Earthscope

The EarthScope Data Portal team consists of members from the GEON project at the San Diego Supercomputer Center (SDSC), Incorporated Research Institution for Seismology (IRIS), University NAVSTAR Consortium (UNAVCO) and International Continental Scientific Drilling Program (ICDP).

The goal of the EarthScope Data Portal is to provide a single point of access to discover and download EarthScope data from the United States Seismic Array (USArray), Plate Boundary Observatory (PBO) and San Andreas Fault Observatory at Depth (SAFOD) experiments. These data are stored in archives at IRIS, UNAVCO, and ICDP, respectively. The beta version of the EarthScope Data portal is hosted at the San Diego Supercomputer Center and can be accessed at http://es-portal.geongrid.org.

The EarthScope Portal leverages the significant portal development efforts of the GEON Project at the San Diego Supercomputer Center, SDSC, and the development of web service interfaces at the three data archive facilities. The portal is implemented using the open source GridSphere portal software infrastructure which supports the well-known Java portlet interface, viz. JSR 168 or the Portlet API.  It uses a set of “core” portlets that have been developed in GEON for Data Registration, Search, and Workspace Services.

Geo Grid

The GEO Grid project (Global Earth Observations Grid) is based at AIST, Japan. The goal of the project is to provide an e-science infrastructure for the Earth Sciences community, including a set of services for accessing remote sensing and geologic data.

GEON’s collaboration with GEO Grid is in developing interoperability between the two environments such that a search request in GEON also searches the metadata catalogs of GEO Grid. We are interested in providing GEON users access to the large amount of ASTER data that is readily available in GEO Grid. The catalog interoperability will be supported using OGC’s Catalog Services for the Web (CSW) standard.

GEO Grid researchers are using the high resolution airborne LiDAR data from GEON to validate the DEMs generated using lower resolution, satellite-based ASTER data available in GEO Grid.

This particular activity is being supported as part of GEON’s participation in the PRAGMA project (Pacific Rim Assembly for Grid Middleware Applications). PRAGMA is supported by the U.S. National Science Foundation under grant, #0627026.

GEON India

imageimageGEON-India is a collaboration with the University of Hyderabad, India, with their Center for Modeling, Simulation, and Design (Prof. Arun Agarwal, Director) and the Center for Earth and Space Sciences (Prof. K.V. Subbarao, Director). The goal of GEON-India is to establish a data hub at the University of Hyderabad for sharing earth science data in India, via the GEON network.

The GEON-India activity was launched in October 2005, with a GEON Workshop at the University of Hyderabad, following a meeting of the PRAGMA project at the same venue. The project was formally launched in Summer 2007 with a grant from the Indo-US Science and Technology Forum. The co-PI institutions involved in this project in India include the University of Pune and the University of Jammu.

A second GEON workshops was conducted in August 2007. The third workshop is currently being planned for January 2009.
The project collaborations involve establishment of a GEON node at the University of Hyderabad, reciprocal visits by research personnel and graduate students.

Chesapeake Bay Environmental Observatory (CBEO)

Chesapeake Bay Environmental Observatory (CBEO) is partnered with GEON project for the use of technology and infrastructure for accessing data and tools along with creating collaborative platform for the Environmental Community.

A Prototype System for Multi-Disciplinary Shared Cyberinfrastructure: Chesapeake Bay Environmental Observatory (CBEO)

The CBEO Project, led by Prof. William Ball, Johns Hopkins University, is organizing disparate observations data for the Chesapeake Bay, developing a range of spatio-temporal interpolation models and services, and using the data to model and visualize hypoxia-related variables. The team consisting of environmental researchers, hydrologists and computer scientists received a 3-year NSF award, under the Cyberinfrastructure for Environmental Observatories: Prototyping (CEO:P) program, to develop and deploy relevant data and services via a “data node”, based on the GEON software stack, thereby leveraging many of the advancements and tools already developed by GEON. The CBEO research plan includes resolving complex cross-disciplinary issues of semantics, syntax and interoperability as well as developing new shared CI tools for data assimilation and interpolation.

The CBEO cyberinfrastructure team is led by Prof. Michael Piaceski, Drexel University (co-PI), who is collaborating with SDSC’s Ilya Zaslavsky, Director, Spatial Information Systems Lab and a member of the GEON teamimage. The CBEO portal uses a customized version of the GEON portal implementation. The system has been designed such that both portals use the same physical metadata catalog but different logical namespaces.

The CBEO project is supported by the U.S. National Science Foundation, under grant #0618986.


The Digital Archeological Record project (tDAR)

image The Digital Archeological Record project (tDAR) Project is a collaboration among a team of archaeologists and computer scientists at the Arizona State University with the goal of designing and developing a digital information infrastructure for systematically collected archaeological data.

tDAR has been a technology collaborator of GEON. The project is developing a portal based, initially on the concepts developed in the GEON portal, including the ontology-enabled data integration technologies.
Using the GEON portal code base as a starting point has allowed tDAR to become operational much more quickly, allowing the project to focus more quickly on specific integration issues in the archaeology domain.  Though the research domains are different (earth science vs. archaeology), the underlying technologies are applicable in both fields.

A separate code repository had been established to enable concurrent development of software between tDAR and GEON.

tDAR is supported by the U.S. National Science Foundation under grant #0624341.


Geosciences Information Network

A coalition of the state geological surveys (AASG), the U.S. Geological Survey (USGS), GEON, and other partners will receive about $625,000 over 3 years from NSF under the INTEROP solicitation to start building a distributed, interoperable data network. AASG and USGS estimate they collectively maintain over 3,000 data bases or data sets.  The GIN project will develop standardized services to make these data accessible online in a distributed network using a few standards and protocols, and work with data providers to implement these services.

The key components of this network are 1) catalog systems for data discovery; 2) service definitions that define interfaces for searching catalogs and accessing resources; 3) shared interchange formats to encode information for transmission (e.g. various XML markup languages); 4) data providers that publish information using standardized services defined by the network; and 5) client applications enabled to utilize information resources provided by the network. The GIN will integrate and utilize catalog resources that currently exist or are in development.

The Geosciences Information Network project will be managed by the Arizona Geological Survey on behalf of the Association of American State Geologists (AASG) in partnership with the USGS.  In addition to GEON(http://www.geongrid.org), the Earthchem (http://www.earthchem.org) network is an active partner.  Collaborators include GIS software company ESRI, and the OneGeology consortium of 80 nations that is building a global digital geologic map. 


Navajo Technical College

In September 2008 Navajo Technical College (NTC) in Crownpoint, NM hosted a GEON-oriented workshop.  GEON was joined by representatives from the TeraGrid Science Gateways program.  The goal of the meeting was to discuss how GEON as a TeraGrid Science Gateway could be utilized in NTC classrooms.  Initially, NTC will be installing a GEON node to connect them to the GEON system.  Discussions about the future of the GEON/TeraGrid/NTC collaboration are in progress.  Please stay tuned for more information on this collaboration.
