We would like to express our deepest sympathies to all those affected by the disaster in the Izusan area of Atami City and pray for the souls of those who have died. ]
From the "red map" and "red three-dimensional map" that I often see, I can read a lot of information that is useful for disaster response, which cannot be understood from ordinary topographic maps and drone images. It is an epoch-making "invention" map.
Various types of map representations have been devised as easy-to-understand topographic maps, but the "red stereoscopic map" allows you to grasp the topography as if you were looking at a stereoscopic photograph, even though it is a planar image.

(Bottom) Enlarge the past "red three-dimensional map" of the same place. It is clear that the embankment continues in a staircase pattern, and it can be seen how the land was created by the "embankment". On the left is a mega solar (large-scale solar power generation facility) that is argued to be one of the causes of disasters. The facility operator seems to say, "There is no problem because the water flows on the opposite side of the embankment," but it can be seen that the trees have been cleared over a wide area.

This "red three-dimensional map" has been evaluated as an epoch-making invention in the history of maps, but the "inventor" was Mr. Tatsuro Chiba of Asia Air Survey.
Born in Ishinomaki City, Miyagi Prefecture in 1956, Chiba is a geologist and volcanologist who is also familiar with the field of disaster prevention. He entered the Department of Applied Geography, College of Arts and Sciences, Nihon University in 1975, studied geography in 1979, and joined Asia Air Survey in 1989 after working as a deputy assistant in the Department of Applied Geography at the same university.
