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@social.wildeboer.net I've not heard of this being done in an urban setting. Is it as disruptive as I expect, or does it sort of manage to be bearable?

@JigmeDatse It鈥檚 not disruptive in my direct experience (they did this in my neighbourhood a few years ago). They place the sensors (geophones) beforehand by hand. On a specific day the trucks come, place themselves on the street, typically, do two or three sweeps that take a minute, drive to the next position, repeat. A few days later the sensors are picked up. That鈥檚 it.
