This paper presents a methodology of data conversion from GIS to urban area models which are used for the numerical simulations of natural disasters. The key point of the methodology is the use of intermediate data, i. e., GIS is converted to the intermediate data from which the models are constructed. Two kinds of intermediate data are developed, and they are converted to models for non-linear seismic response analysis and for flood and volcano eruption simulations. The robustness of the data conversion is examined, and commercial GIS is successfully converted to urban area models for earthquake, flood and volcano eruption simulations.
