U.S. Chart No. 1 describes the symbols, abbreviations, and terms used on nautical charts. It is produced by NOAA and the National Geospatial-Intelligence Agency. The symbols for paper charts and their analogous digital products, such as NOAA raster navigational charts (NOAA RNC®) are shown, as well as the symbols used to portray NOAA electronic navigational charts (NOAA ENC®) data on Electronic Chart Display and Information Systems (ECDIS).
Paper copies of U.S. Chart No.1 may be purchased from a NOAA certified printer; visit the NOAA's Chart No. 1 page for more information.

Pilot Charts depict averages in prevailing winds and currents, air and
sea temperatures, wave heights, ice limits, visibility, barometric
pressure, and weather conditions at different times of the year. The
information used to compile these averages was obtained from
oceanographic and meteorologic observations over many decades during the
late 18th and 19th centuries.
The Atlas of Pilot Charts set is comprised of five volumes, each covering a specific geographic region. Each volume is an atlas of twelve pilot charts, each depicting the observed conditions for a particular month of any given year.
The charts are intended to aid the navigator in selecting the fastest and safest routes with regards to the expected weather and ocean conditions. The charts are not intended to be used for navigation.
The United States Coast Pilot® consists of a series of nautical books that cover a variety of information important to navigators of coastal and intracoastal waters and the Great Lakes. Issued in nine volumes, they contain supplemental information that is difficult to portray on a nautical chart.
Topics in the Coast Pilot include channel descriptions, anchorages, bridge and cable clearances, currents, tide and water levels, prominent features, pilotage, towage, weather, ice conditions, wharf descriptions, dangers, routes, traffic separation schemes, small-craft facilities, and Federal regulations applicable to navigation.
