The Office of Coast Survey produces NOAA Raster Navigational Charts (NOAA RNC®) to support marine transportation and coastal management. RNCs comply with International Hydrographic Organization standards and include updates for Notice to Mariners corrections. RNCs support marine navigation by providing official digital charts for electronic charting systems, including the Electronic Chart Display and Information System (ECDIS).
NOAA RNC® files are available for free download. Coast Survey also supports a program by which entities may be certified to download, redistribute, repackage, or in some cases reformat, official NOAA RNC® data, and have those RNCs retain their official status. No other process results in redistributed NOAA RNC® data that comply with Federal chart carriage regulations.
The NOAA RNC® Distributorship Agreement and instructions for application are available for download.
