We visualized a hotspot from the sky over the waste storage space inside the Fukushima Daiichi Nuclear Power Station using a remote radiation imaging system consisting of a drone equipped with a Compton camera. By superimposing the images of the hotspots on the 3D building model of the waste storage space created using a photogrammetry, we succeeded in drawing the map that can easily recognize the positions of the hotspots in the actual working environment.
