The OWET Cumulative Effects Analysis Framework is a multi-criteria decision making tool for evaluating the potential impacts of various ocean renewable energy technologies. The tool is designed to provide decision makers, stakeholders and the public more information about the potential impacts associated with various development scenarios. The tool includes three main parts: data library of applicable resource data; resource and development interaction database; and a user interface that combines the data and interaction to allow for alternatives analysis. The final product is a GIS tool for assessing various development scenarios and the potential impacts and benefits.
