This paper focuses on the creation of a methodology for automatic real world adequate geosimulation model preparation, based on GIS models and statistical data collected. The urban environment is a network that exists among different structures, links, flows and relationships. The spatial distribution and development direction of the territory, also business environment development is determined by a street network and transport communication network. This information is well formed in GIS models. As the GIS models are static, they cannot be used to determine any dynamics of the territory; however, the urban environment is nonlinear. A possible way to solve nonlinearity is to prepare geosimulation models, as they are more informative for dynamic processes than GIS models. Geosimulation models also allow making experiments and solving optimization tasks. `The automatic creation of geosimulation models does not require deep knowledge of simulation techniques for domain specialists further using them.
