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! https://giga-m.de (in German) #Geothermic #Vibroseis #Research
