Remote Sensing Role in Land Use StudiesCase Study: Tehran Metropolitan and its Boundary

Land is a limited and vulnerable resource with many permanent and renewable benefits if it is used appropriately.By considering the limited lands and the need for updated data and information for land planning, necessity and importance of land use studies is clear. In fact remote sensing data with geographic information systems are strong tools in change detection of land use pattern. They are much cost and time effective.In this study, satellite image has been used for extraction of update land use map of Tehran metropolitan. Three different methods (unsupervised classification, supervised classification and visual interpretation) have been utilized for preparation of land use map.
