| Abstract: | To plot a diagram of density distribution,AIS information,especially position information,is used and a proper algorithm for grid diagram of density distribution was designed.Based on dynamic tables and static tables in the AIS database as data source,the algorithm makes a grid diagram of density distribution display successfully on the electronic chart using stored procedures and database access techniques,and its importance is that it has density distribution showed visually by means of application and the second development of electronic chart system.The study suggests that this algorithm is feasible,convenient and highly accurate. |
