Nautical charts contain information on water depths, navigational aids, shipping channels, and restricted areas. They may also show details of coastal settlements, shorelines, reefs, and other physical features. These charts are collected for research purposes and are not intended to be used for navigation. Most charts in the Earth Sciences & Map Library are produced by the National Ocean Service (NOS), the National Geospatial-Intelligence Agency (NGA), and their predecessors.
