AVCS ENC Grey Area Unsurveyed Data

 Example of an ENC showing a “greyed out” area:
                                                                                                                                                                                                                                                                                                                                                                               

There is no survey data within greyed out areas. The Pick Report on the vessels ECDIS will show this.
