NOAA to Shut Down RNC Tile Service

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.

The RNC tile and seamless services provide repackaged chart images that are based on the traditional nautical chart products that are being cancelled. As these charts are cancelled, a patchwork of holes will grow within the coverage of the raster services, which will eventually render them unusable. Therefore, the RNC Tile Service and the Seamless RNC Services will be turned off early in the raster sunset programme. The online RNC Viewer displays data from the RNC Tile Service, so it will be shut down at the same time.
