Full story HERE.A Swiss research group has developed a drone-carried sensor that can detect the water content of terrain below, and are offering it as a cheaper and more accurate measurement supplement to existing technology like satellite imagery. Its creators say the device can optimize a variety of terrain management decisions in a world where drought and fires are becoming a major, recurring problem.
This sort of geological tech isn't exactly new, similar remote sensing devices have been around for several decades - e.g. Stängle's sc
From the look of the company website, they anticipate a wide range of uses for these drones; but I don't think water dowsers are out of a job just yet.
