The increasing trend of urbanization and consequently the rapid growing of the physical space of the cities is considered as one of the significant features of the human today’s life. On this basis, using proper and efficient strategies in leading the physical development of the cities in suitable beds can be considered as an inevitable factor in the process of urban planning. One of these strategies is implementing efficient techniques in prioritizing lands suitability for development of urban constructions.
In the present study, by selecting the cities of Ardabil, Nir, Namin and Sarein as the case study, it is tried to test a combination of GIS and TOPSIS model capabilities in an experimental context of the study subject and the resulting outputs be presented in the form of a classified drawing of lands suitability for urban development.
To this end, forming evaluation criteria, standardization of criteria drawings for the membership degree in fuzzy function, determining the criteria weight by CRITIC method and preparing weighted standardized maps were the measures be taken that in consequence of their performance, the required arrangements were provided for functional use of TOPSIS model in GIS environment. Review of the results obtained from using model in the study area, showed that the introduced prioritized pixels in the output of model have optimum conditions from the view point of defined criteria. Therefore, this model can be used as a decide supporting system (DSS) in the process of choosing proper beds for the city physical development.
