Is there some kind of 3D radar that scans a few meters below surface level? Sounds like that would make the job of recording a lot easier.

- beloch 10y agoYes, ground penetrating radar/sonar/magnetic sensing all exist and are used, but they're not as good as you'd hope. They're mainly used to help figure out where to dig. There are all sorts of high-tech ways to record the position of artifacts as they're being dug up, but students and volunteers with pens, notebooks, and a little training are usually cheaper.
