ELECTRONIC NAUTICAL CHARTS (ENC) and RASTER NAUTICAL CHARTS (RNC)

The United States Coast Guard (USCG) vessels requires updated electronic charts in ELECTRONIC NAUTICAL CHARTS (ENC) and RASTER NAUTICAL CHARTS (RNC) format for their areas of operation, which includes U.S., Canadian, Latin American, and Caribbean waters, as well as other select areas. The Electronic Charts provide source data to Coast Guard Command and Control Systems which are critical to the direct fulfillment of military and intelligence missions, as well as safe navigation. The primary system supported is ECDIS (Electronic Chart Display and Information System). Most electronic navigational charts for the U.S. waters are available from the National Oceanic and Atmospheric Administration (NOAA), National Geospatial Intelligence Agency (NGA) or the US Army Corps of Engineers (USACE). Charts for non-U.S. waters will need to be acquired from or produced on the authority of various International Hydrographic Offices such as the United Kingdom Hydrographic Office (UKHO).
