| summary |
Urban spatial models are important to many professions, and they can be used in a wide range of urban decision - making applications. This paper describes a methodology for automatic generation of an urban spatial model from a GIS source. The methodology uses a Voronoi polygon - based method in order to split the urban space. After partitioning the GIS, functional characteristics are used to generate zones of interest at each Voronoi polygon. The paper also presents examples of applications of the model: a two dimensional model used for microsimulation of traffic, and a three - dimensional model used for simulation of air pollution. |
