dc.description.abstract The urbanization process effects both structure and function of the cities. Therefore, the analysis of morphological patterns of a particular urban area have evolved as a result of varying factors of demographics, level of economic development, political structure, environmental effects, etc. Hence, analyzing of urban morphology is necessary for predicting the urban changes such as impact of climatic changes in urban context and understanding the urban processes such as urban sprawl onto agricultural lands and wild habitats, and the expansion of residential land use at the urban fringe. To understand and predict the urban processes, it is needed to monitor and characterize the spatial patterns of the urban area by observing them at different states in time. Aerial photography or field surveys were commonly used for analyzing and to understand the spatial structure of a city. However, these methods are very expensive, more labor intensive and difficult to detect morphological patterns over a long period of time. Therefore, Remote sensing technique with the combination of Geographical Information System (GIS) employed as an effective tool in analyzing the morphological patterns both qualitatively and quantitatively in a timely and cost effective manner. Remote Sensing is the measurement or acquisition of information of some property of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object or phenomenon under study. An increased use of remote sensing data in urban analysis could be observed in past years. The timely and spatially explicit characteristics of remotely sensed data not only provide a means for exploring and testing hypotheses and models about urban areas, but also for constructing new theories that can help in the formation of policy in anticipation of the problems that accompany urbanization processes (T. Rashed, J.R. Weeks, D. Stow, D. Fugate, 2005). It is observed that the use of Remote Sensing data for urban analysis is very popular among the planners.
