GEON's Outreach Extends to Fall AGU Meeting

Several GEON PIs and graduate students presented their project-related work at the 2006 Fall AGU Meeting, held in San Francisco Dec 11-15th. Ramon Arrowsmith (Arizona State University) and Chaitan Baru (San Diego Supercomputer Center) chaired an informatics session, while Randy Keller (University of Oklahoma) served on the panel at the Geoinformatics Town Hall meeting. Others who had papers or posters at the meeting included Chuck Meertens (UNAVCO), Dogan Seber (SDSC), A. Krishna Sinha (VA Tech), Chris Crosby (ASU), Greg Bensen (Univ of Colorado), and Han Kim (UCSD). GEON, again, hosted a booth in the Exhibition Hall the full week of the meeting, providing demos and talking to the community about the GEON portal and our current resources and tools.

GEON Node to be Deployed by Chesapeake Bay Environmental Observatory Network (CBEO)

A team of environmental researchers, hydrologists and computer scientists from several universities across the country recently received a 3-year NSF award, under the Cyberinfrastructure for Environmental Observatories: Prototyping (CEO:P) program, to develop and deploy the "Chesapeake Bay Environmental Observatory (CBEO)". The CBEO proposed to host data and services via a “data node”, based on the GEON software stack, 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 project's specific focus is on organizing disparate observation data for Chesapeake Bay, developing a range of spatio-temporal interpolation models and services, and using the data to model and visualize hypoxia-related variables. Dr. Ilya Zaslavsky from the San Diego Supercomputer Center and Prof. Michael Piaceski, Drexel University, are two of eight PIs involved in this consortium, both of whom continue to have strong involvements with GEON.

GEON Co-PI re-elected to IEEE-Computer Society Board of Governors

Ann Q. Gates (Co-PI, UTEP) was re-elected for a second term on the Board of Governors of the IEEE-Computer Society. She chairs the Awards Committee for the Society, and is completing her term as secretary of the Executive Committee. Dr. Gates also continues to serve on the 'Task Force on the Role of Cyberinfrastructure in Competitiveness' as part of the CI Advsiory Committee to NSF.

UTEP Graduate Students Draw From GEON Research for Master's Theses

Two UTEP Graduate Students, Flor Salcedo and Jose Luis, completed their Master's theses that included work that being driven by GEON research and technologies. Flor Salcedo's thesis was entitled "A Method for Designing Computation-Driven Ontologies in the Geosciences". This thesis defined a method for designing a computation-driven ontology that facilitates knowledge discovery and understanding as well as the definition of concepts and relationships that support composition of services. Visual techniques were developed to support the design method and a case study based on knowledge about gravity, an area of interest in GEON, was conducted to evaluate the method. Flor has subsequently been hired by Rockwell Collins.

Jose Luis' thesis was entitled "A Virtual Supermarket for Remotely Sensed Data and Images (AVS)" and involved the development of a prototype of a new generation of remotely sensed data search engines. The emphasis on this work was on public domain digital data where users can locate remotely sensed datasets that cover continental areas comprehensively and differ by sensor, spatial resolution, spectral resolution, cost, and location. The project emerged from the Software Engineering course and will be tied to the UTEP GEON portal.
