National Oceanic and Atmospheric Administration (NOAA) paper charts now available online in raster format

All official nautical paper charts produced by the Office of Coast Survey (OCS) of the National Oceanic and Atmospheric Administration (NOAA) are now available in raster format and are free to the public to download via the Internet. 

The files offered are geo-referenced, full-colour images of NOAA's paper nautical charts, published and updated weekly by NOAA in the BSB format. Raster Navigational Charts (RNCs) are produced by scanning at high resolution the original colour separates which are used to print the paper charts. NOAA adds to the digital raster file such features as data describing the chart, its datum, projection, and its geo-reference. Geo-referencing enables a computer-based navigation system that is connected to a Global Positioning System (GPS) to locate and display on the chart image on screen the vessel's exact position.

Raster Navigational Charts are an official product of NOAA and meet the S-61 Standard – Raster Navigational Charts – of the International Hydrographic Organization (IHO).
