基于MapObjects的中国近海船舶防台系统研究

Study on the Typhoon-avoidance System for Chinese Coastal Vessels Based on MapObjects

根据中国近海船舶防台的实际需要,利用GIS控件MapObjects开发了西北太平洋热带气旋显示系统.系统主要实现了显示和预测台风、船舶的位置与路径,测量台风与船舶间的距离和方位两项功能.实测结果表明该系统克服了传统标绘的不足,能为船舶防台提供准确的参考数据.

Based on MapObjects, a controlling unit of GIS, the Northwest Pacific tropical cyclone dis- played system was developed to avoid typhoon for Chinese coastal vessels. The system realized principally the following functions ： （ 1 ） to display and predict the position and path of typhoon and vessels; （2） to survey the range and azimuth between typhoon and vessels. The system overcomes the deficiency of traditional plot- ting method and provides reliable data for typhoon-avoidance for vessels. The actual testing result indicates that the system overcomes the deficiencies of the traditional plotting method and provides reliable reference data for typhoon -avoidance by vessels.
