NOAA Raster Navigational Charts In the United States, all official nautical paper charts produced by NOAA's Office of Coast Survey (OCS) are available in raster format. A fundamental tool of marine navigation, NOAA's Raster Navigational Charts (NOAA RNCs™) are produced by scanning at high resolution the original color 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 GPS to locate and display on the chart image on screen the vessel's exact position. For technical questions about the NOAA RNCs™, its format or the standards involved; and for questions related to production scheduling or cartographic content of the NOAA RNCs™, please click Here for NOAA's Nautical Chart Product Inquiry page.

IMO APPROVES STANDARDS FOR RASTER CHART DISPLAY SYSTEM (RCDS) RCDS Mode of Operation - (This is the RCDS Performance Standard that will be submitted to IMO for adoption. Its adoption will allow carriage of RCDS to meet the SOLAS requirements for charts.)
