Abstract : This report is the Software Development Plan (SDP) for an ArcGIS module called Model Verification and Validation (MVV). The software's purpose is to assist an expert analyst in evaluating the accuracy of model forecasts of currents in coastal areas. The MVV module is implemented as part of the Geospatial Analysis and Model Evaluation Software (GAMES) library. This report describes the components of the SDP: (1) conceptual model (data structures and theory); (2) logical model (methods); (3) physical model (code); and (4) demonstrations. The data structure utilizes ocean and coastal features that are instantiated from model predictions and validation data sources. The logical model implements computer-based tools to compare these instantiations. The software consists of modular code that is compatible with other GAMES modules (e.g., ARCOAS). The system is demonstrated for models of the northern Gulf of Mexico and Yellow Sea.
