May 10, 2021 NOAA (National Oceanic and Atmospheric Administration) will shut down its Raster Navigational Chart (RNC) Tile Service and the online RNC Viewer on 1 October 2021. The NOAA Seamless Raster Navigational Chart Services will be shut down on 1 January 2022. This is part of a larger NOAA programme to end the production and maintenance of all NOAA traditional paper and raster nautical charts that was announced in the Federal Register in November 2019. Cancellation of traditional NOAA paper nautical charts and associated raster nautical chart products, such as BookletCharts and RNCs will occur over the next four years and be completed by January 2025. More information about this overarching programme to ‘sunset’ traditional nautical chart products is available on the Farewell to Traditional Nautical Charts web page.
