Over time we have chosen to differentiate our fleet without ever giving up the availability of a fixed wing UAV.
Fixed wing UAVs allow you to cover large surfaces in a short time, transporting sensors optimized for in-flight shooting (both in the visible, in the thermal, and in the multispectral); these UAVs normally need to fly at relatively high altitudes (a few tens of meters) in order to avoid obstacles, therefore allowing relatively low resolutions on the ground (GSD> 3Cm / Px) and providing “nadiral” views of the ground (the camera axis is perpendicular to the ground).
The rotary wing UAVs, on the other hand, allow greater mobility also on the vertical plane, maintaining, if necessary, a fixed shooting position; this allows you to get closer to the objects to be taken and thus increasing the resolution on the ground (GSD <1Cm) and also to take photographs of mainly vertical development objects (such as the facade of a building or a very steep slope).
On the other hand the former normally have (with the same battery charge capacity) a greater flight range, but the photographs of vertically developed objects are more complex.
