Marine Cadastre Spatial Database

The Multipurpose Marine Cadastre team has produced several national-scale spatial datasets to support planning and decision-making in the coastal and marine environment. By providing standardized data in a readily useable format, the Marine Cadastre Spatial Database provides the framework data needed by coastal and marine spatial planning professionals, while reducing the costs associated with collecting and processing spatial data.
