机场净空保护区建设项目磁方位的计算确定

Calculation and Determination of the Magnetic Azimuth of the Construction Project of Airport Clearance Protection Area

磁方位是民用机场净空保护区建设项目净空高度审核的一项特殊要求,在无实测仪器设备条件下,基于已有的坐标方位等测绘成果,通过科学合理的计算确定磁方位就具有现实意义。本文结合具体工程实例,确定磁方位计算方法,完成了民用机场净空保护区建设项目净空高度审核测绘报告,供参考借鉴。

Magnetic azimuth is a special requirement for clearance height audit of civil airport clearanceprotection project. Under the condition of no actual instrument and equipment and based on existing mapping results such as coordinate and orientation, it is practical significance to determine magnetic orientationthrough scientific and reasonable calculation. Combined with specific engineering examples, the calculationmethod of magnetic azimuth is determined, and the clearance and height audit report of civil airport clearance protection project is completed for reference.
