I am developing CV systems for agribusiness and have been grappling with this issue. The solution seems to be a combination of the two systems. Quads are great for some tasks like herd detection/sorting/counting and spotting problems in planting. For crop dusting, seed planting, geo surveys in general you go with fixed wings.

Yeah, one of the approaches we're looking at involves using fixed wings to cover 98% of our surveys and "mopping up" the areas we can't hit with a quadrotor (e.g. near power lines, trees, other keepout zones)
