The National Oceanic and Atmospheric Administration (NOAA) <a href='https://www.nauticalcharts.noaa.gov/mcd/enc/' target='_blank'>Electronic Navigational Charts</a> (ENC), found in the A-16 <a href='https://www.fgdc.gov/initiatives/ngda-management-plan' target='_blank'>National Geospatial Data Asset</a> Portfolio, support real-time navigation as well as collision and grounding avoidance needs of the mariner, and accommodate a real-time tide and current display capability that is essential for large vessel navigation. The NOAA ENC will support all types of marine navigation by providing the official database for electronic charting systems, including the Electronic Chart Display and Information System. NOAA ENCs will also provide fully integrated vector base maps for use in geographic information systems that are used for coastal management or other purposes. The NOAA ENCs are in the International Hydrographic Office S-57 international exchange format and comply with the ENC product specification. The ENC Harbor map service displays data compiled for ENC products with a scale range from street level (1:5,000) to town level (1:50,000).<div><br /></div><div>The ENC data used within this application will be updated weekly.
