The National Oceanic and Atmospheric Administration (NOAA) established certification requirements for applicants who want to redistribute NOAA electronic navigational charts (NOAA ENC®) as official data.
Two types of certification are available. The first type, Certified NOAA ENC® Distributor (CED), covers NOAA ENC® downloading, exact copying, and redistribution of those copies. The second type, Certified NOAA ENC® Value Added Distributor (CEVAD), permits reformatting official a NOAA ENC® into a System Electronic Navigational Chart (SENC) using type-approved software, and distribution of that SENC.
NOAA intends by this action to assure that, though redistributed, quality official NOAA ENC® data is offered to the public in support of safe navigation on U.S. waters.
