Abstract
The Multipurpose Marine Cadastre (MMC) is an integrated marine information system that provides jurisdictional, legal, physical, ecological, and human use data in a common geographic information system (GIS) framework. Essentially, 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 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.
