UAV photogrammetry over Knuckles cloud forest canopies: structure-from-motion orthomosaics?

Generating centimeter-accurate Structure-from-Motion (SfM) orthomosaics across the steep, cloud-prone escarpments of the Knuckles mountain range requires rigorous flight planning. Survey missions must fly during narrow morning weather windows (6:00 AM to 9:00 AM) before thermal mist blankets the upper ridge lines. Cameras must be configured with mechanical global shutters and fixed prime lenses (24mm or 35mm equivalents) to prevent rolling shutter distortion during high-speed grid turns across steep mountain contours. Overlap settings must exceed 85% forward and 75% side lap to ensure accurate image matching across complex forest canopy textures.
