The locations of permanent or temporary installations intended to support basic human activities or needs, including communication, transportation, shoreline protection, housing, recreation, and utilities. Data required for marine planning are limited to infrastructure that has effects on environmental processes or human activities that impact the coast, Great Lakes, or ocean. Distributions are maps representing current locations of structures and facilities. Assessments are maps showing theoretical or suitable locations resulting from models, evaluations, or other processes; or they are models that evaluate the ecological or economic impacts of existing infrastructure. Predictions are maps showing predicted locations based on expected outcomes or variable factors and drivers; or they are models that evaluate the ecological or economic effects of proposed, changed, or future infrastructure. All Infrastructure data share these definitions for Distributions, Assessments, and Predictions.
