The boundaries of geographic areas that are defined for governmental, administrative, or management purposes. Governance data for marine planning are those that identify governance entities that have effects on environmental processes or human activities that impact the coast, Great Lakes, or ocean. Distributions are maps representing authoritative boundaries (for examples, see http://marinecadastre.gov). Assessments are maps showing theoretical boundaries resulting from models, evaluations, or scenario-testing; or they are modeled values of bounded regions. Predictions are maps showing predicted boundaries based on expected outcomes or driven by variable parameters; or they are models predicting impacts of moving boundaries. All Governance data share these definitions for Distributions, Assessments, and Predictions.
