This paper summarises the general pattern of urban land-cover change in the Northeastern Illinois between 1972 and 1997 using Landsat acquired remotely sensed images. The region, centred by the city of Chicago, experienced dramatic land cover change in the past decades. Accompanying the redistribution of population and decentralisation of metropolitan functions are the tremendous growth and dev...

the issue of urban decline in city centers and horizontal expansion of the city and its consequences is a challenge in sustainable development of the cities. in this regard, new approaches were shaped to define career planning, urban design and urban environmental quality concerns in new-urbanism pattern. the critical approach to modern urban pattern was formed based on scattered, non-human and...

strong sentiment against the phenomenon known as “urban sprawl” has emerged in the United States over the past few years. Critics of sprawl argue that urban expansion encroaches excessively on agricultural land, leading to a loss of amenity benefits from open space as well as the depletion of scarce farmland resources. The critics also argue that the long commutes generated by urban expansion c...

Accurately detecting urban expansion with remote sensing techniques is a challenge due to the complexity of urban landscapes. This paper explored methods for detecting urban expansion with multitemporal QuickBird images in Lucas do Rio Verde, Mato Grosso, Brazil. Different techniques, including image differencing, principal component analysis (PCA), and comparison of classified impervious surfa...

Cities in developing countries are facing serious problems as a result of rapid urban population growth. Not the least of these problems is the creation of environmental stresses at the rural-urban fringe of these cities as they increase in area and envelop fertile surrounding agricultural lands. Because of this rapid rate of growth, sustainable urban environmental management (SUEM) policies an...

Developing countries have been undergoing dramatic urban growth over the past three decades. It is essential to understand and simulate the urban growth process for smart urban planning and sustainable development purposes. Cellular automata (CA) modeling is an efficient approach to simulating urban land use/cover change; however, the traditional CA method has limitations in simulating the vari...

From the past to the present time, in all civilizations and countries, urbanization is considered the most striking evolution of human societies. With the advent of the industrial revolution and the rapid expansion of cities, societies were faced with numerous problems. One of the most significant problems is Extreme centralization in one city or more and fragmentation of urban hierarchical sys...

â  regional and urban planning instruments contain an extensive range of concepts and methods. these methods are important for understanding the complex identity of cities and the prediction of their future. today majority of planners and urban planning authorities believe that the use of these methods can help us to better understand urban systems and predict their behavior. in this regard the...

In this paper, built-up land expansion patterns and the associated factors were characterized in urban and non-urban areas across the Wen-Tai region of eastern China. Fractal dimension can be used as a reliable indicator of the complexity of built-up land form, and the increasing trend of fractal dimension indicated a more complex, dispersed pattern of built-up land in urban areas. Spatial regr...
