A central issue around which the recent growth literature has evolved is that of urban sprawl. The process of urbanization is a universal phenomenon taking place the world over, where human settle. Expansions of interest in the modeling and analyzing of this process and the problems to which they are applied should be taken in account. Urban planners require information related to the rate of growth, pattern and extent of sprawl to provide basic amenities. Patterns and extent of sprawl could be modeled with the help of such information. This paper brings out the extent of sprawl using Geographic Information System (GIS) and Remote Sensing imagery. These techniques based study is carried out to comprehend the process of sprawl. In one hand, geographic positioning, topology and surface measurements are basic GIS properties which enable highly precise locational referencing of spatial phenomena. The growing uses of Remote Sensed imagery are contributing to unprecedented surveillance of the environment and to monitor and measure urban sprawl in other hand. For this purpose, this paper tries to give some possible reflections that help us to develop the analytical tool that may help us to improving the way towards the amplification of the analysis paradigm. This article focuses on the issues widely and frequently used in the examination of the urban spread out, which are scattered in the literature. It begins by laying out the urban sprawl debate. We will offer an overview and discussion of the contemporary issues related to this phenomenon. Then, the paper follows the GIS assessment conducted along some different ways that consist of the most influential advantages. Finally, we will expose the technique of Remote Sensing imagery which provides several information bases for analysis of the sprawl feature.
