In #Munich, you might see (and hear, feel) this weird machine, making weird vibration and sound sweeps. This is part of the Giga-M project. Its goal is to create a detailed 3D map of the underground in Munich and surrounding areas (in total 1100 square kilometres) that will be made available as #OpenData to assist in planning geothermic plants. Switching away from fossil fuel for heating. Impressive!

A so-called Vibro Truck. A heavy metal plate is lowered to the ground and a vibration sweep is initiated. Thousands of probes are distributed all over the city that receive these sweeps, allowing to create a detailed 3D map of the underground, showing potential hot water streams that can be used for geothermics.

@jwildeboer Could it also determine the location of any buried WWII ordnance?

@jwildeboer okay. I see. I just keep hearing about that being a problem, and wondered if there were technology to find it all and remove it. In one case, it interfered with the ability to fight a wildfire. It's astonishing how much there still is, buried.
