Scanning for sinkholes

I was wondering about this again about this so I did a search

Found some articles

It quickly dawned on me that drones can do this sort of work.

Drones can do this as well.

Ground penetrating radar from drones?

Worth a trial. Reflection off the ground surface would be fierce, which is why gpr tends to be operated as close to the surface as possible. Also weight may be a problem, perhaps because batteries are heavy.

But I’m willing to stick my neck out and say that both problems can be overcome.

Wookie, give molly his handle back.

It’d be fun having a tree radar of my own.

I did have an ultrasound imager for a while. I was using it to see through steel plates, perhaps that could be used for studying tree health?
