Remote sensing (RS) and geography information system (GIS) are the main technologies for assessing expansion and rate of land cover changes. Knowing the different kinds of land cover changes and human activities in different parts of lands, as the base information for different planning is especially important. In this study, the land cover changes of Isfahan city that is consist of Isfahan and its` surrounded area was studied for the past 4 decades. This area is banded by 32º 49  40.15 and 32\&\#1771; 32 38.95 northern latitude and 51\&\#1771; 26 27.17 and 51\&\#1771; 49 58.27 eastern  longitudes For researching the study objectives, the aerial photos with scale of 1:50000 taken in 1955 and ETM+ (Enhance thematic mapper) images from Landsat satellite taken 2001 and the topography maps of Isfahan city and its` surrounding was used. All of the aerial photos and satellite image with the nearest neighbour sampling were georegistered with the RMSe less than one pixel. For image processing, the best false coloured composite image was first produced according to optimal index factor (OIF). Then land cover maps of the studied area were produced in 5 classes by using the combination of supervised and unsupervised classification and Normalized difference vegetation index (NDVI). At the end, the produced maps compared with post"=classification method. The results have been showed that the urban area has increased during study period and its area became 7.5 times bigger. The most of croplands and orchards have been destroyed in the around of Isfahan urban area.
