Brief Description of the Collaboratory :

 

GEON is a collaboration between computer scientists and geoscience researchers with the goal of creating a modern cyberinfrastructure for the earth sciences. Specifically, GEON's purpose is to enable scientists to access, synthesize, and model geoscience data from a wide variety of sources. GEON will consist of digital libraries containing freely available data from many geoscience disciplines, along with an integrated set of software tools for access, analysis, visualization, and modeling. Integrating, analyzing, and modeling geoscience data is a major challenge because of the extreme heterogeneity of data formats, storage and computing systems, and conventions, terminologies, and ontological frameworks that are found in the disciplines that comprise the earth sciences.

One of GEON's main goals is semantic integration. To that end, GEON researchers developed an ontology based search prototype for geological maps that allows users to integrate maps from nine state geologic surveys in the Rocky Mountain region. Previously, this was a time-consuming task because of the different classification schemes used by the states. GEON is also utilizing ontologies developed by other geoscience projects such as CHRONOS and the Southern California Earthquake Center Community Modeling Environment(SCEC/CME).

GEON grew out of a series of NSF-funded geoinformatics workshops that began in 1999. The early meetings did not include computer scientists. With encouragement from NSF, geoscientists began talking with computer scientists, and each discipline realized that they could help the other. For example, computer scientists understand ontologies, but they do not have the domain knowledge to develop them. In the beginning, communication between the geoscientists and computer scientists was difficult, but this has improved over time.

GEON has a mostly informal management structure. There is no single person who makes decisions. Major decisions are made with input from project participants. Some formal structure is needed, however, to respond to matters that require a quick turnaround. The Internal Coordinating Committee (ICC), comprised of 6 people, deals with ongoing issues that do not require participation from all GEON members. The ICC meets weekly via videoconference. GEON Principal Investigators (PIs) meet face-to-face twice a year, and an All Hands Meeting is held once a year.

Access to Information Resources :

  GEON is at the beginning of its development, so few resources are currently available. GEON researchers have developed an ontology-based search for geology maps. Geology maps are difficult to integrate from one state or country to another because, for example, different terms are used to describe the same geologic time period. In the next couple of months (i.e. summer of 2004) a first version of the GEONgrid portal should be available. It will allow users to experiment with the ontology based map search and five or six other demonstration projects. The ultimate vision of the GEONgrid portal is to provide tools for data discovery and access and to provide a temporary workspace for users to conduct their research activities such as copying GEON data sets of interest, modifying them if needed, and utilizing them in any of the GEONgrid's functionalities. GEON recently teamed up with TeraGrid, which will provide the project with additional access to supercomputers and to powerful desktop systems. GEON's partnership with Lawrence Livermore Laboratory will also increase the computational resources available.

GEON has developed three methods for data sharing. Large data holders, such as the U.S. Geological Survey, maintain their own data but serve it in a way that is accessible by GEON. Individuals have two ways in which they can make data available. First of all, people can obtain software from GEON and establish a GEON node and then maintain the data themselves. Secondly, individuals can give their data to GEON to serve and maintain. All data sharing approaches require data owners to provide metadata. GEON project participants are currently discussing the minimum level of metadata required.
 
 

Access to People as Resources :

  Communication between computer scientists and geoscientists and among geoscientists from different sub-disciplines is often very challenging. Face-to-face meetings between project participants are highly valued because they are seen as an efficient way to improve communication. Every six months, the Principal Investigators (PIs) meet face-to-face at one of the geo-PI institutions. The first All-Hands Meeting took place in San Diego in May 2003, and there are plans to meet annually from now on. In addition, joint workshops are held between geoscientists and computer scientists as needed. Scientists who are not participants in GEON are invited to these as necessary. Videoconferencing and e-mail lists are other means that participants use to communicate. The Internal Coordinating Committee (ICC) is a group of 6 people that meets weekly via videoconference.
