Five map layers stacked over the Shonan coast at night: satellite imagery, building dots, landforms, an earthquake shaking grid and land price pins. On the right, DATA TIMES editor-in-chief Kaito Ogasawara peers out from behind the band with a puzzled look. Text: AI, 165,411 buildings, one by one. TOO MANY LAYERSLATEST HANDS-ONNEWHands-onBUSINESS14 MINA disaster register for 165,411 buildings, from free data alone: we had an AI layer satellite, terrain, quake and land-price data onto Fujisawa's PLATEAU modelWe asked an AI to pull all 165,411 buildings in Fujisawa, Japan, from the PLATEAU 3D city model and write five free public datasets onto each one: GSI landforms, large-scale fill sites, J-SHIS earthquake shaking odds, Sentinel-2 satellite change and official land prices. In about an hour and a half it had a city-wide disaster register. Among the tenth of buildings most prone to strong shaking, only one in four would be colored on a flood hazard map; satellites found a development site before the 3D city did; and tsunami-zone land still rose in price. Here is how we built it, where we tripped up, and what a register can and can't say about one building, with reproduction steps.
Opening a café? Which station? In a sunny seaside station plaza, DATA TIMES editor-in-chief Kaito Ogasawara, in a navy apron, rests his chin on his hand with a doubtful look, holding a tablet showing a map with three circles. On the right, giant black letters on a yellow band read "Which station?" under a small red tag reading "Opening a café?"NEWHands-onBUSINESS16 MINOur editor wants to open a seaside café.
