Drone survey was a pricey lesson in limits
Back in 2016 I was running a small crew doing grading work outside of Fort Wayne, tracking progress with a clipboard and a wheel measurer. Got talked into renting one of those fancy survey drones for a week, $1,200 including the operator and the software license. We mapped out a 40 acre lot in about three hours that would have taken us two full days on foot. But then the data files came back in some proprietary format that our field tablets could barely open, and the office laptop crashed twice trying to export it. We still had to walk the site to verify a few bench marks because the drone missed a drainage ditch under heavy tree cover. So that $1,200 gave us a pretty picture but didn't replace the boots on the ground. Now I'll rent it again for the big topo shots, but I keep a paper roll and a 100 foot tape in the truck for the spots the tech can't reach. Has anyone else found those drone surveys are only worth it for flat, open land or am I missing something?
