 Unmanned aerial vehicles, UAVs, are commonly used for photogrammetric surveys in hillside areas where the terrain is uneven and the altitudes vary significantly. Contour mission flight planning, CMFP, which involves designing flight plans based on a digital elevation model, DM, and the desired flight altitude, is a better alternative than equal altitude mission flight planning, EAMFP. CMFP provides greater consistency in the ground shooting distance during image capture, resulting in more accurate and reliable point cloud data. Additionally, CMFP requires less planning and operational time compared to EAMFP, making it a viable option for UAVs in hillside areas. This article was authored by Chiushangxi, Darnhorn CO, and D.
