Abstract: 

Remote sensing technology has shown its great capabilities to solve many earth resources issues. One of the most important applications of this technology is to detect land use/cover changes happened over a certain period of, time. In this study, an attempt has been made to study urban land use/rover changes over a period of 10 years from 19-09-1988 to 04-4-1998. Using PCI Geomatica software package and after careful registration of two Land sat TM image data sets on each other, different digital image processing techniques such as simple image differencing, principal component analysis (PCA) and fuzzy logic were used to generate the change map of the city of Tehran, Iran. Most of the observed changes were in vegetation land use/cover category. The change image generated in this work could be a useful tool to urban managers for investigating and monitoring illegal use of land at urban areas.
