Remote sensing is commonly performed via airborne platforms such as satellites, specialized aircraft, and unmanned aerial systems (UASs), which perform airborne photography using mounted cameras. However, they are limited by their coverage (UASs), irregular flyover frequency (aircraft), and/or low spatial resolution (satellites) due to their high altitude. In this paper, we examine the utilization of commercial flights as an airborne platform for remote sensing. Namely, we simulate a situation where all aircraft on commercial flights are equipped with a mounted camera used for airborne photography. The simulation is used to estimate coverage, the temporal and spatial resolution of aerial imagery acquired this way, as well as the storage capacity required for storing all imagery data. The results show that Europe is 83.28 percent covered with an average of one aerial photography every half an hour and a ground sampling distance of 0.96 meters per pixel. Capturing such imagery results in 20 million images or four petabytes of image data per day. More detailed results are given in the paper for separate countries/territories in Europe, individual commercial airlines and alliances, as well as three different cameras.
遥感通常通过机载平台来进行,如卫星、专用飞机和无人机系统(UAS),这些平台利用安装的相机进行航空摄影。然而,由于其高度较高,它们受到覆盖范围(无人机系统)、不规则飞越频率(飞机)和/或低空间分辨率(卫星)的限制。在本文中,我们研究了将商业航班用作遥感的机载平台。具体而言,我们模拟了一种情况,即商业航班上的所有飞机都配备用于航空摄影的安装相机。该模拟用于估计覆盖范围、以此方式获取的航空图像的时间和空间分辨率,以及存储所有图像数据所需的存储容量。结果表明,欧洲83.28%的地区被覆盖,平均每半小时进行一次航空摄影,每像素的地面采样距离为0.96米。捕捉此类图像每天会产生2000万张图像或4PB的图像数据。本文针对欧洲不同国家/地区、各商业航空公司和联盟以及三种不同相机给出了更详细的结果。
