摘要
针对利用经纬度坐标表征空域的不足,提出了基于GeoSOT网格的空域栅格化表征方法。首先,分析了空域的栅格化表征具有简洁高效、便于协调通报的相对优势,并对美军典型的网格系统进行剖析;其次,结合飞行基本规则、飞行间隔规定,设计了面向空域表征的网格参考系统的剖分方案和编码结构;最后,根据网格最少和精度对应原则给出点状、线状、区状空域的详细栅格化表征流程,并在网格平台进行空域表征场景示例应用分析,为空域表征提供了一种新的技术手段与实践思路。
In view of the shortcomings of airspace representation being characterized by using latitude and longitude coordinates,a method of airspace raster is proposed based on GeoSOT grid.Firstly,the airspace raster representation being concise,good in efficiency,and easy in coordination and report,some typical grid systems of the U.S.Army are analyzed.Secondly,combined with the general flight rules and flight interval regulations,a division scheme and a coding structure of grid reference system for airspace representation are designed.Finally,according to the principle of minimum grid and precision correspondence,the detailed raster representation flow of point,line and area airspace is given,and the application analysis of airspace representation scenario is carried out on grid platform.This provides a new technical means and practical ideas for the airspace representation.
