Assessment and Analysis of Spatial Expansion of Tabriz Metropolitan Using Multi Temporal Satellite Images

Abstract

Tabriz metropolitan expansion has caused a large valuable land to go under construction. Therefor, this applied and experimental research was done to achieve goal investigation urban sprawl and land use changes in Tabriz metropolitan using multi temporal satellite images in 27 years period by object-oriented classification technique. This paper also based on historical and causal methodology evaluated spatial development of Tabriz metropolitan in 1984-2011 using multi temporal Landsat 5 and 7 images that obtained from U.S. Geological Survey organization and object oriented image processing techniques. The Results showed that the area of Tabriz metropolitan changed from 7220.34 hectares in 1984 to 22346.82 hectares in 2011. Considerable area of the recent development is located on agricultural and garden land that decreased 6470 hectares of mentioned land use needs management of urban future growth using mass building production, high-rise building production policies(compact city), using Bare land in the urban(infill development), urban development directed in other direction of agricultural land.
