Drone flight parameters for Forestry

FORESTRY

• Forward overlap : 80% ⁽³⁾
• Side overlap : 80% ⁽³⁾

• Flight height : between 80 m and 110 m
• Forward overlap : 70%

• Forward overlap : 80% ⁽³⁾
• Side overlap : 80% ⁽³⁾

• Set GCP (otherwise, use a PPK enabled UAV and a GPS base station)
• ⁽³⁾ We must have 80% overlap on the canopy. Ex : For a flight height at 120 m AGL, and the trees’s height is equal to 30m, then the Forward/Side overlap must be set at 83%/83%
• Add additionnal UAV trajectories outside the Area of Interest
• For projects with multiple flights there should be overlap between the different flights and the conditions ( sun direction, weathers, etc..)
• Set GCP
• Avoid to fly during azimut sun period or when the sun is low (shadows)
• Avoid to fly when the weather is alternating between sunny and cloudy
• Take pictures of the calibration panel BEFORE and AFTER the flight (multispectral).
