Development of robust method to construct urban area model used in Integrated Natural Disaster Simulation

Abstract

INDS (Integrated Natural Disaster Simulation) is a seamless simulation of disaster, damage, and social reaction. A model must be constructed from GIS (Geographic Information System) for a target urban area. This paper presents the data conversion of GIS of DMD (Digital Mapping Data) format. A key issue is the compensation of lacked data. Several new algorithms are studied, and the most robust one is found; the successful conversion rate reaches more than 99%. The data conversion is applied to Kochi City, and it is shown that the constructed model is able to be used in simulating seismic structure response and emergency mass evacuation.
