"TSUJIDO Area" Disaster Prevention Map using GIS (Geographic Information System)

Abstract

The disaster prevention map of each district of 13 arias of Fujisawa city in Knagawa is revised every 6-8 years. The map of Tsujido district, one of 13 arias of Fujisawa, made in 2001 was needed to be updated. The disaster prevention map project was started up in April, 2004, and investigation was carried out by the citizens group "Tsujido citizens meeting" and Tsuchiya laboratory in Shonan Institute of Technology. In making a disaster prevention map in the past, inefficiency in the field survey and the map making was a big problem. Then, I tried to apply a new method using IT tools such as GIS (map information system) and cellular phone with GPS (Global Positioning System) to this investigation to improve accuracy and efficiency. Information of about 480 places in total was acquired as a result of the investigation that had been executed in May-July, 2004, and the disaster prevention map was completed in March, 2005, and was distributed to the citizens in Tsujido district.
