摘要
准确绘制机场净空障碍物限制面图才能精确计算机场净空保护区内物体的航空限制高度。根据《民用机场飞行区技术标准》定义的各类型障碍物限制面,分析出各类限制面的关键折点及定义范围,并设计算法实现了净空点所在限制面类型的判断及限制高度计算,开发了基于高德地图的净空查询APP,具有较强的实用价值和参考价值。
Accurate mapping of aerodrome obstacle limitation surface is the basis of exact calculation of object height limit in aerodrome clearance area.The paper analyses the key vertices and ranges of various types of restriction surfaces according to Technical standard for flight area of Civil Airport and the algorithm is also designed to realize the judgment of the type of restriction surface and the calculation of the limit height.An clearance area inqurie mobile application based on amap is developed,which has strong use and reference value.
