【Abstract】 To plot a track distribution map,AIS information,especially position information,was used and a feasible and sound algorithm for track distribution map was designed.Based on dynamic tables and static tables in the AIS information database as data source,the algorithm made a track distribution map displayed successfully on the electronic chart using stored procedures and database access techniques.The conclusion was that this algorithm was feasible,convenient and had high-accuracy.更多还原
