In: Maxwell, R., Hill, M., Zheng, C. and Tonkin, M. (Eds.), Proc.

Interpretive Summary: This paper provides an overview of the GMI (Geospatial Modeling Interface) simulation framework for environmental model deployment and assessment. GMI currently provides access to multiple environmental models and contains advanced data processing and visualization features including: (1) editing and visualization of geospatial model input data; (2) the ability to input measured experimental data for robust statistical model evaluation; and (3) geospatial output visualization across space, time, and modeling scenarios including capabilities for real-time post-processing (e.g., on-the-fly color ramping) and querying. GMI leverages the GeoWind open source GIS platform that integrates Open Geospatial Consortium standards (as implemented in GeoTools) within NASA's World Wind Java SDK. The overall vision of the GMI development effort is the creation of a geospatial modeling framework that allows rapid integration of environmental models and enhances enables the scientific modeling process through state-of-the-art visualization components.

Technical Abstract: This paper provides an overview of the GMI (Geospatial Modeling Interface) simulation framework for environmental model deployment and assessment. GMI currently provides access to multiple environmental models including AgroEcoSystem-Watershed (AgES-W), Nitrate Leaching and Economic Analysis 2 (NLEAP2), Soil and Water Assessment Tool (SWAT), and Root Zone Water Quality Model 2 (RZWQM2). GMI data processing and visualization features include but are not limited to: (1) editing and visualization of geospatial model input data; (2) the ability to input measured experimental data for robust statistical model evaluation; and (3) geospatial output visualization across space, time, and modeling scenarios including capabilities for real-time post-processing (e.g., on-the-fly color ramping) and querying. GMI leverages the GeoWind open source GIS platform that integrates Open Geospatial Consortium standards (as implemented in GeoTools) within NASA's World Wind Java SDK. The overall vision of the GMI development effort is the creation of a geospatial modeling framework that allows rapid integration of environmental models and enhances enables the scientific modeling process through state-of-the-art visualization components.
