Unmanned aerial vehicles can collect high-resolution and real-time photos while emitting fewer greenhouse gases than ordinary airplanes and therefore are considered economic and environmentally friendly platforms. However, quantitative analyses of the sustainability of using unmanned aerial vehicles for aerial photography based on their performance and technical constraints compared to that of airplanes are lacking. The purpose of this study is to analyze the economically and environmentally appropriate monitoring coverage of unmanned aerial vehicle photogrammetry according to wing type (such as fixed-wing and rotary-wing types) and desired image resolution (such as 5 cm/pix and 20 cm/pix for the ground sample distance). To determine the sustainable monitoring coverage, the total photogrammetry costs must include the social cost to reduce the emitted greenhouse gases during operation, resulting in a feedback relation. As a result, the sustainable monitoring coverage of fixed-wing unmanned aerial vehicles should be less than 27.50 km when the resolution is 5 cm/pix and 30.64 km when the resolution is 20 cm/pix. Rotary-wing unmanned aerial vehicles are sustainable when their monitoring coverage is less than 23.98 km at a resolution of 5 cm/pix and 26.75 km at a resolution of 20 cm/pix. These results provide information on the number of unmanned aerial vehicles and the standing unmanned aerial vehicle deployment plans required to monitor the survey area.
无人飞行器在排放较少温室气体的情况下，可获取高分辨率、实时的照片，因此被认为是经济且环保的平台。然而，与飞机相比，基于性能和技术限制，无人飞行器航空摄影的可持续性定量分析尚不完善。本研究旨在根据机翼类型（例如固定翼和旋转翼类型）和所需图像分辨率（例如地面采样距离为 5cm/pix 和 20cm/pix），分析无人飞行器摄影测量在经济和环境方面的适当监测覆盖范围。为了确定可持续监测范围，总摄影测量成本必须包括运营过程中减少温室气体排放的社会成本，从而产生反馈关系。因此，当分辨率为 5cm/pix 时，固定翼无人飞行器的可持续监测范围应小于 27.50km，当分辨率为 20cm/pix 时，可持续监测范围应小于 30.64km。当分辨率为 5cm/pix 时，旋转翼无人飞行器的可持续监测范围应小于 23.98km，当分辨率为 20cm/pix 时，可持续监测范围应小于 26.75km。这些结果提供了有关监测区域所需的无人飞行器数量和固定部署计划的信息。
