Measuring the Quality of Urban Places by Using MulticriteriaEvaluation Method in GIS(Case Study: Tehran City)

Studying Quality of Life (QOL) is becoming an important tool for evaluating public policies, ranking places, as well as understanding and prioritizing the problems that communities face with, developing and monitoring management and urban planning strategies. In this study, quality of place has been considered as the resources, facilities and opportunities that are provided by the environment to meet human needs as subsets of quality of life. Integration of remote sensing, census and other spatial data in GISenvironment using Multicriteria Method is employed in order to access the quality of place forthe city of Tehran. Three main domains, including social, access and physical as a criterion to determining and using factor analysis from a total of 49 parameters components related to each domain were identified. Component weights associated with each domain using hierarchical analysis extracted and final index of each domain by weighted linear combination of components of the standard were created and finally, the three domains of social, access and physical in order to extract the ultimate indicator of quality of place through the multi-criteria evaluation in GIS environment were combined together. In addition, using the index spatial analysis Gi, optimal and critical clusters in each domain was determined. The results showed that in the social domain north and central northparts, in the access domain central parts and in the physical domain north parts of Tehran are desirable areas; ultimately, the spatial analysis of quality of place index shows that the north and central north of Tehran are desirable areas; but west, southwest and south parts of Tehran are critical ones. The results of correlation analysis between social, access and physical domains showed significant positive relationship between social domain with access and physical domains..
