Potential NASA Commercial Applications: The proposed ModelLab will support NASA applications across three critical areas of interest. First, it will address NASA's need for creative new methodologies that can harness computing power necessary to process large geospatial datasets efficiently. Efficiency in this context is largely a matter of faster processing times, and the proposed project promises to increase these speeds significantly for geospatial modeling. Second, it can assist the Langley Research Center's GIS Team, which is recognized as a leader in GIS technology. ModelLab will be designed for integration with existing geospatial data processing toolkits from both commercial and academic sources that can be aligned with Langley objectives on a project-by-project basis. Finally, ModelLab will be a tremendous addition to NASA's open data resources by providing a catalogue of geospatial models that can be used to support internal research, classroom study, and public outreach activities with available NASA datasets.
