Abstract: 

In urban areas, overpopulation has turned many agricultural lands into residential, commercial and industrial ones. These changes have had such undesirable effects on urban environment as a decrease in vegetation and an increase in temperature. Therefore, it is necessary to evaluate the effects of land use changes for the proper management of urban areas.

Remote sensing technique can provide good information about land use changes in a short time. It can also be used to study the past changes in land use to predict the future changes.

The main objective of this study was to develop a methodology for monitoring land use changes in urban areas using satellite data and remote sensing technique.

In a case study, four cities in the province of Yazd, Iran, were selected. To map temporal changes of urban vegetation, Normalized Difference Vegetation Index (NDVI) were derived using Land sat ETM+ data bands (1990 and 2002). Then, the NDVI values were classified into six groups to study the quality of these changes in the above-mentioned periods.

The results of this study indicate spatio-temporal changes of urban vegetation in the last decade.
