Abstract

Background: Today's informal neighborhoods are one of the major issues in the large cities. There are many reasons for the formation of these types of fabrics in cities. Urmia city which is one of the relatively large cities of Irān and the second important settlement center in the northwestern part of it faces the problem of suburbs in its body.
Objectives: This research, which identifies and describes the type of the informal fabrics in Urmia, is applied in terms of its objectives and it is analytical-descriptive in terms of nature and methodology.
Method: For this purpose, at first, five basic criteria with seven sub-criteria that are involved in the typology and identification of the informal fabrics were selected. Then, the conceptual model and the internal relation between the criteria were organized by the ANP network model. After that, using the Super Decisions software, the final weight of the indicators was obtained and using ArcGIS, all the relevant information layers were formed. After creating the map from the mentioned layers, by applying the weight of the criteria, and the combination and overlapping of the layers, the overall condition of the city of Urmia was obtained in terms of the values of the urban fabric indicators and typology.
Result: Finally, by appropriate classifications in the ArcGIS environment, the informal and marginal neighborhoods were fully identified and determined. 

Highlights

It should be noted that the above neighborhoods occupy a considerable space of the city, Empowerment and strategic planning should be used to improve their situation.
