The Hydrographic Note is a standard reporting model that requires information to the mariners when they discover new or susceptible navigation hazards, when they observe some changes in the aids to navigation or consider as necessary the corrections to analogue and electronic charts or nautical publications of the Maritime Hydrographic Directorate. This safety navigation information is broadcasted within the radio navigation warnings and afterwards edited in the Notices to Mariners.
