3. CHOOSING UAV SYSTEM
3.1. Proposed Criteria for a Suitable System
Several studies have proposed different criteria for choosing UAV with imaging capabilities. However, they all agree that the main requirements for a suitable UAV are high resolution, accuracy, low cost, and portability
(Lemmens, 2011; Skaloud et al.,2006).
Other studies added other operational consideration such
as the size and weight of payload; stability and vibration; number of people needed for launch and control; level of piloting skills; flight time; range; minimum airspeed; minimum size of takeoff and landing area; and safety. One may also add that data processing has to be largely automated and there should be no
need for ground control points
