3D MAP:Useful Advanced Observing Satelite for mapping, damage prediction of a natural disaster, water resource research


The Japan Aerospace Exploration Agency (JAXA) is starting to process the precise global digital 3D map using some 3 million data images acquired by the Advanced Land Observing Satellite "DAICHI" (ALOS). The digital 3D map to be compiled this time has the world's best precision of five meters in spatial resolution with five meters height accuracy that enables to express land terrain all over the world. Hence its strong character will prove useful in various areas including mapping, damage prediction of a natural disaster, water resource research etc. In order to popularize the utilization of the 3D map data, JAXA will also prepare global digital elevation model (DEM) with lower spatial resolution (of about 30 meters under our current plan) to publish it as soon as it is ready. Its use will be free of charge.
