This could reduce the redundancy that comes with manual surveying which could take up a long time, even weeks at a stretch.
One drone flight might be everything it takes to track a lot of metrics and data points altogether.
There is no hindrance anymore in terms of difficult terrains, steep slopes, and hard-to-reach or inaccessible areas when you deploy drones for the mission.
Drone technologies help with 3D models and mapping that will help us arrive at volumetric measurements with topographic data thus making these digital surveys more accurate
