飞机上带有北斗导航或者GPS等定位装置，能够实时确定飞机的空间位置，获得其高度，经纬度等信息；飞机上载有光电吊舱，能够从高空拍摄图像或视频，并且能够通过其自带的传感器实时获得光电吊舱自身的倾斜角度、视场角度等信息；结合飞机所处的空间位置，光电吊舱的倾斜角度、视场角度以及地理信息系统就可以计算出光电吊舱所看到的区域所在的地理位置，并在地理信息系统中显示出其区域；若对图像中的某一局部区域感兴趣，需要确定其地理位置，则可通过鼠标点击这一区域，程序就能主动地计算出目标地点的地域坐标，并映射到地理信息系统中，将其标注出来。(Aircraft with the Beidou navigation or GPS and other positioning devices, can determine the location of the aircraft in real time, access to its height, latitude and longitude and other information; The aircraft is equipped with photoelectric pods, can take pictures or video from high altitude, and through its own sensor real-time access to the photoelectric car's own tilt angle, angle of view and other information; The geographical position of the area seen by the photoelectric pod can be calculated by the spatial position of the aircraft, the tilt angle of the photoelectric pod, the angle of view and the geographic information system, and the area is displayed in the geographic information system. If you want to determine the geographical location of a local area in the image, you can click on the area by clicking on the area. The program can automatically calculate the geographical coordinates of the target location and map it to the geographic information system.)
