Contexto
Sufficient flexibility and tailoring of information for the first set-up of automation in AIS is achieved by the use of the geographical reference qualifier. This qualifier consists of latitude and longitude to one minute resolution and referenced to the World Geodetic System - 1984 (WGS-84) geodetic datum and a three-digit distance figure giving radius of influence.
