 note = {Recently, UAV (Unmanned Aerial Vehicle) technology has been developed rapidly. UAV allows engineers to use remote sensing at lower cost than satellite images or aerial photos. The expansion of business for UAV is expected. However, UAV can take photos in local areas, not the global area. Then the authors covered areas without pictures by UAV using aerial photograph from aircrafts. The objectives of this study were to identify possibilities for remote sensing with three types of photography (aerial photographs, panoramic photographs, and UAV photographs) and to monitor vegetation covers. The data were processed through five main steps: (1) to obtain aerial photographs in research sites from Geographical Survey Institute, (2) to take pictures with digital camera in 360 degrees in research sites, (3) to flow UAV with two filters, IR72 and IR90 in research sites, (4) to construct a 3D model in research sites with PhotoScan, and (5) to analyze vegetation covers with GIS., 長崎大学大学院工学研究科研究報告, 47(88), pp.7-12; 2017},
