Projects > Joint Laboratory for Geosciences Interoperability Partnership (JLGIP)

1. Overview

Geoscience Interoperability Office (GIO, NASA) and College of Science (COS), George Mason University (GMU) share common goals in the areas of interoperability for systematic development and application of computing systems for the understanding of Earth scientific phenomena and the analysis of Earth science data obtained by observing, experiments, modeling, database search, and instrumentation.
The Joint Laboratory for Geosciences Interoperability Partnership (JLGIP), based on the collaboration between GIO and GMU, conducts research, development, and outreach in interoperability for Earth science and applications, related data systems, and associated technologies in order to provide furtherance of the ultimate goals of NASA's Science Mission Directorate, of which GIO and other programs are integral parts.

2. Activities

2.1 Institutional support:

Dr. Phil Yang participated in the institutional support for the Geosciences Interoperability Office by providing scientific and technical analysis. He serves as the NASA INCITS/L1 alternate to participate in the bimonthly meeting and standards analysis for GIO. He serves as the GIO outreach contact to Public Health program and assisted Dr. John Evans managing the technical side of PHAiRS interoperability project. He also analyzed interoperability vision, objective, and scientific coordination for tasks conducted at George Mason University. These tasks include:
  1. Earth Science Gateway Host & Maintenance (ESG H&M).
  2. Earth Science Gateway and Earth Information Exchange Partnership (ESG-EIE) with the Federation of Earth Science Information Partnership.
  3. Portal and ESG advancement analyses and experimentation.
  4. Interoperability Testbed (Testbed) for public health and high performance computing.
  5. AAG CISG collaboration.
  6. Research to Operations and Jason III Pilot Concept.

2.22 ESG H&M:

Wenwen Li, Bin Zhou and Fuming Lin supported the maintenance and running of ESG at GMU. It is quite stable with good performance in the months with a stable running time of about 99%. This running system supported other GIO projects, such as OWS5 and ESIP-EIE.

ESG and EIE:

Zhenlong Li, Wenwen Li, Haijun Zhu, Qunying Huang, and Jing Li developed ESG-EIE with support from ESIP and other partners, and the second phase is accomplished. The developed EIE is highlighted in ESIP 2008 winter meeting. Through the development and collaborations with Drs. Rob Raskin, Karl Benedict, Stefan Falke, and Will Pozzi, and other relevant partner agency representatives, more functions and portlets are featured in ESIP 2008 summer meeting.

Portal and ESG advancement:

Based on advancements analysis and experimentation conducted by Drs. Ruixin Yang, David Wong, Fuming Lin, Wenwen Li, Qunying Huang, Jing Li and Haijun Zhu with a variety of professionals from the field through informal and formal discussions, meetings, and workshops. Focused development are conducted on 1) multidimensional visualization including time based on Worldwind and Google Earth, 2) semantic search based on ontology, and 3) linkages/harvesting to more catalogs through interoperable interface (if available) or proprietary interfaces.

Interoperability Testbed:

Dr. Jibo Xie and Mr. Bin Zhou, Fuming Lin developed the testbed environment for the project of leveraging model interoperability and high performance computing to improve public health applications. The environment is installed with ESG and setup with 30 CPU Cores and connection to the Internet (1Gbps) and the LamdaRail (1Gbps). A 244 CPU Core cluster is also available and could be dedicated when needed for earth science simulations and modeling. A 1600 CPU cluster is acquired by College of Science at GMU and will be available for this project on a negotiation/needed basis.

AAG CISG:

Collaborated with NASA JPL, American Association of Geographers, Phil Yang, David Wong, and the JLGIP team established the Cyberinfrstructure Specialty Group within AAG. The organization is dedicated to share geospatial information and other resources for the geographers. For example, exposing Earth science information in a manner that can be easily utilized by geographers.

R2O:

Dr. Phil Yang assisted Ms. Myra Bambacus in Research to Operations analysis and Jason III Pilot Concept development for collaboration with NOAA.

3. Accomplishment

3.1 Institutional support:

Dr. Phil Yang participated in the institutional support for the Geosciences Interoperability Office by providing scientific and technical analysis. He serves as the NASA INCITS/L1 alternate to participate in the bimonthly meeting and standards analysis for GIO. He serves as the GIO outreach contact to Public Health program of importance to societal benefits. He also analyzed interoperability vision, objective, and scientific coordination for tasks conducted at George Mason University. These tasks are detailed as following and include:
  1. Earth Science Gateway Host & Maintenance (ESG H&M).
  2. Earth Science Gateway and Earth Information Exchange Partnership (ESG-EIE).
  3. Earth Science Gateway Evaluation, Verification, Validation, and Benchmarking (ESG EVV).
  4. Interoperability Testbed (Testbed).

3.2

For ESG H&M, Bin Zhou and Wenwen Li supported the maintenance and running of ESG at GMU. It is quite stable with good performance in the months with a stable running time of about 99%. This running system supports other GIO projects, such as OWS5, GEO, and ESIP-EIE.

3.3

Wenwen Li, Zhenlong Li, Haijun Zhu developed ESG-EIE with support from Compusult and other partners, and the first phase is just accomplished. The developed EIE is demonstrated in 4 sessions within the ESIP summer meeting. 100 brochures and 30 presentation copies of the EIE system are distributed in the meeting. ESIP requested a second phase development and we are scheduling that with the portal community including Drs. Rob Raskin, Karl Benedict, Stefan Falke, and Will Pozzi, and other relevant partner agencies representatives, such as Ed Washburn (EPA) and Tim (NOAA).

3.4

ESG EVV is conducted by Drs. Ruixin Yang, David Wong, Fuming Lin, and Haijun Zhu and Manny Smith with a group of 23 professionals. 6 teams are formed to evaluate the function of ESG and each ESG function is evaluated by 3 teams (12 persons). The evaluation is done and the analysis will be submitted in one to two months. Functions need improvement will be recommended for the next phase development of ESG. ESG Benchmarking will be done in the fall.

3.5

Drs. Jibo Xie and Bin Zhou developed the testbed environment for the tasks of leveraging model interoperability and high performance computing to improve public health applications. The environment is installed with ESG and setup with 30 CPU Cores and connection to the Internet (1Gbps) and the LamdaRail (1Gbps).
