Abstract
It is required to build the analytical model of the target area for the simulation of urban spreading fire. The modeling often costs us tremendous labor and time. In this study, an automatic modeling system using the digital residential map is proposed. Almost all the data, which are necessary for the simulation of urban spreading fire in an earthquake, are made automatically and written in the files by just only assigning the target area in the map. The techniques used in the automatic modeling system are introduced. Using this system, a simulation of urban spreading fire is demonstrated.
