Feasibility of Infill Development using Fuzzy Multivariate Analysis Case study: Urmia Urban

This research from the methodology aspect is the descriptive-analytic and categorized in the development - applied type. The required data were collected using library and documentary studies. Environmental, social and physical criteria were identified in 12 variables. Then, by preparing the layers of each criterion, we defined the weight of each layer based on its importance in the infill development analysis. In this study, the Analytical Hierarchy Process (AHP) was applied by Expert choice software for prioritizing, the weighting of criteria and fuzzy multivariate analysis model in GIS environment for production, weighting, and fuzzy combination of layers were used. Finally, using the weights obtained from AHP Analysis, the suitability map for infill development of uremia was prepared using Fuzzy Overly extending in ArcGIS software and the exponential population growth model and land per capita are used to predict the amount of land that could be effective for preventing urban growth sprawl using infill development option. The results showed that from the total of 5502.6 hectares of Uremia, 367.83 (6.69%) of the land quite suitable, 863.55 hectares (15.71%) of land medium suitable, 1448.91 hectares (26.33%) somewhat inappropriate, 1721.25 hectares (28.31%) inappropriate, and 11.61% (20%) are totally inappropriate and the amount of land that can be increased by the applying of an infill development strategy for preventing of urban sprawl growth estimated at 3680000 square meters in the 1405.
