  • NOAA RNCs may be redistributed, but redistributed NOAA RNCs are NOT considered official NOAA RNCs, and do not meet federal chart carriage regulations for regulated vessels. This official status attends only to the original downloaded files. NOAA has established a program under which distributors be certified to redistribute NOAA RNCs such that the RNCs will retain their official status and meet applicable chart carriage regulations. The RNC agent agreement can be viewed at http://www.nauticalcharts.noaa.gov/mcd/Raster/dist_require.html.

    NOAA RNCs and their geoTIF versions (future) may not be used to print commercial products. Individuals may print the NOAA RNCs or their geoTIF versions for personal use, but the result is not a NOAA chart, and may not be used to meet federal chart carriage regulations.

    Copying of the NOAA RNCs to any other server or location for further distribution is discouraged unless the following guidelines are followed: 1) this User Agreement is displayed and accepted by anyone accessing the NOAA RNCs, and 2) a reference to this Web site is included so that anyone accessing the NOAA RNCs is advised of their origin.

    If these NOAA RNCs are incorporated into any other product in a form other than as provided by NOAA, the producer of that product assumes full liability and must adhere to conditions described in the paragraph above concerning copying. These maps are not for navigational purposes.  Only government approved charts should be used for navigation.  ePi Rational, Inc. assumes no liability for omissions or errors or from any loss or damages from using this software.   Please see https://charts.noaa.gov/RNCs/RNC_Agreement.shtml for further details on the User Agreement of RNC's.
