Production of Land Use Map Using RS and GIS A Case Study: Pakdasht

Pakdasht is located in southern foothills of Alborz mountain. Its area estimated km2. It possesses high agricultural potential. Its close proximity to Tehran (km) has turned it into one of the most attractive migrant center. This unprecedented migration rate in turn, has led to the unpleasant urban physical expansion and agricultural destruction.Thus, the major objective of this study is first to investigate the physical characteristics of the region. This is followed by creation of land use map in order to detect all of the physical changes toward subsequent needed planning management.The research method of this study is followed by production of topographic map of the region along with the corresponding satellite images. As a second step, this map were digited. Through application of GIS, this led to production of elevation maps showing both degree and direction of the elevation of the region. As a further step, relevant processing were done on the satellite images through application of Geomatica software. Superwised classification and maximum likelihood were applied in order to produce land use map.This study suggests that the northern part of the region essentially is not suitable for human habitation in general and agricultural activities in particular. However, southern part possesses high physical poterntials regarding human habitation. This part has drawned a lot of migrants and therefore needs particular attention regarding management issue. According to the finding, the dominant land use is idle lands (). This is followed by agricultural lands () and area under construction (). The area of Pakdasht was hectare prior to. This changed into hectare in. This dictates its physical expansion equal to hectare.
