OP probably meant to say that he uses pre-made Lidar maps to scout locations where he is likely to find lost human artifacts. He's not looking for underground deposits, but trying to find things like long lost outlines of house foundations in the woods. The availability of these maps has made it much easier to find these. Instead of wandering blindly through the woods, you can go straight to a GPS location. It's a big thing in the metal detecting community, and he is not likely to be a bot. Here are some of the maps to check out if you are in the US: https://apps.nationalmap.gov/3depdem/ https://apps.nationalmap.gov/3depdem/.
