Use of unmanned aerial vehicle to calculate soil loss

Satellite remote sensing systems are widely used in environmental studies, for providing regional scale analyses with high temporal resolution. On the other hand, when local small scale spatial studies based on very high resolution data at specific moments are involved, unmanned aerial vehicl...
