Digital Coast - NOAA Coastal Services Center

This data viewer provides the baseline information needed for coastal and marine spatial planning efforts, particularly those that involve finding the best location for renewable energy projects. The Multipurpose Marine Cadastre (MMC) is also a helpful tool in the permit review process. Users pick the ocean geography of their choosing and quickly see the applicable jurisdictional boundaries, restricted areas, laws, critical habitat locations, and other important features. With the MMC, potential conflicts can be identified and avoided early in the planning process.

Technical Specs

• A geographic information system (GIS) data visualization application such as ArcGIS Explorer or Google Maps is necessary to view downloaded spatial data
