The National Oceanic and Atmospheric Administration has stopped offering the paper and associated raster versions of the marine navigation chart for Lake Tahoe – the first chart to be sunsetted under the five-year plan to move to fully electronic navigational charts (ENCs). After August, the agency said in a Feb. 26 announcement, the electronic version will be the only NOAA nautical chart of the area.
The Lake Tahoe chart was selected to test the various system modifications required for ENCs, which provide a detailed representation of the U.S. coastal and marine environment. Going forward, the only updates NOAA will apply to the updates of raster charts are those critical to navigation, such as the location of newly discovered shoals or changes to buoys. Routine information, such as shoreline survey data, will only be updated in the ENCs. If the two versions get too far out of sync, the raster chart may be cancelled earlier.
