Come on. What do they all say?

That's too much work to open and read them all.

The way it works is you open the first one, if you like it, then you open the second one, and so on.....(it says they do it all the time)

Good enough for me.

Many thanks. These are just what I was looking for.

Most of what has been done with UAV's in remote sensing deals with the electromagnetic spectrum - i.e. Ultraviolet-Visible-Infrared portions of "light" some of which we cannot see. To be best of my knowledge, this cannot detect ground water, especially deep ground water, but it will detect higher levels of vegetation growing in one area with respect to another. As to surface water quality, it would be easier to drive up to the river or lake, thief a sample, and test it, or have it tested. I suppose one could actually drag a sonde behind a UAV or have it hover over surface water and sample it, and even measure one or two observables, but this would be pretty limited in scope.

To detect ground water, use a water witch, you will have better results.

"To detect ground water, use a water witch"

How about:

Yeah, but Johnny's gig is presently "out of this world". I have heard of, and seen results with water witching that were not bad at all. I myself have located buried pipes using a similar technique with dissimilar metal rods (copper, iron). It does not seem to matter what the pipe material is.

To find water: (1) locate buried pipe, (2) figure out what kind of pipe it is (gas, oil, water, or electric conduit), and if a water pipe (3) dig an "artesian" well around it, and make a small drill hole in the pipe to match your water requirements. Note: this procedure is (A) highly illegal in every state (especially if you tap into the line), and (B) even more dangerous sincle you already don't know what you are doing if you attempt this. Do not try this at home, on your own property, or on someone else's property. That should cover me legally.
