What does the date entry mean on the NOAA ENC® download page?
Answer – The date shown on the NOAA ENC® download page is the date that the compressed NOAA ENC® archive was last modified. This usually means that a new, updated cell replaced the NOAA ENC® cell file. It may also mean that one or more of the supporting text or picture files was modified. Users should always make sure that they are using the latest version of the NOAA ENC® and its supporting files.
