Recently we took our drone out for some initial flight tests and to see what it was capable of. It dealt pretty well with moderately strong winds and driving rain, using the GPS positioning system to maintain a give location. In many ways it seemed more weather resistant than my colleague and I.
We and the students will need to become quite proficient in flying the drone over quarry benches and then up to the next level and so on. We'll probably use continuous video from which we'll take stills to evaluate the composition of the vegetation.
