Change detection is the process of identifying differences in the state of an object or phenomenon by observing it at different times (Singh 1989; Mouat et al.,1993). “Timely and accurate change detection of earth’s surface features provides the foundation for better understanding and interactions between human and natural phenomena to better manage and use resources” (Lu et al.,2004).change detection normally the entails application of multi-temporal data sets to quantitatively analyse the temporal effects of the phenomenon. Because of the advantages of repetitive data acquisition, its synoptic view and digital format suitable for computer processing, remotely sensed data such as thematic matter (Spot radar and advanced very high resolution radio meter have become the major data source for different change detection application during the past decades cited by Lu et al 2004.remote sensing data have assumed an ever increasing strategic role in several application domains. A wide range of applications can be benefited from the study of change process over a specified area at different times. Information about land use is necessary to update land cover maps and for effective management and planning of the resources for sustainable development.
