Mapping Functions
Ground Sample Distance (GSD):
(H/18.9) cm/pixel, H indicates the aircraft altitude relative to the area mapped (unit: m)

Rate of Data Collection:
Max operating area of approx. 0.63 km2 for a single flight at an altitude of 180 m, i.e., GSD is approx. 9.52 cm/pixel, with a forward overlap rate of 80% and a side overlap ratio of 60%, during a flight that drains the battery from 100% to 30%.
