NOAA’s National Ocean Service – Coast Survey unveils NOAA ENC Online Viewer

For more than ten years, since NOAA introduced its electronic navigational charts, you have needed to purchase a specialized chart display system to view the NOAA ENC® as a seamless chart database. 

Starting today, you don’t need a system to view the ENC depictions; you can use Coast Survey’s new web-based viewer called NOAA ENC® Online.  Since NOAA ENC Online is web-based, there is nothing to download. Users can click on the web map and zoom to selected features or locations, to see the information contained in over a thousand ENCs of NOAA-charted waters and access a number of tools to manipulate the charts.  In addition to providing public access to chart data, ENC Online will also help NOAA cartographers improve our current suite of ENCs. For instance, this web service allows cartographers to more easily pinpoint areas that may need additional hydrographic surveys for chart updates and corrections.  ENCs are increasingly popular with commercial mariners, who value the charts’ flexibility and multi-layered information. Starting today, we hope other chart users will plumb the depths of ENC Online and discover its many uses as a practical resource. NOAA ENC Online is not certified for navigation. It does NOT fulfill chart carriage requirements for regulated commercial vessels under Titles 33 and 46 of the Code of Federal Regulations
