| Abstract: | The function of dynamic track drawing in the ship monitoring system is realized with 3S technology.Based on the system,we could draw the sailing tracks dynamically according to the ship's orientation.These two kernel arithmetics are involved during the system developing process;angle deflexion and distance interval value.The practice of system development shows that the proper application of these two arithmetics comes to good in the visualization of sailing track. |

| Keywords: | GIS angle deflexion distance interval value arithmetic |
