Urban area expansion is one of the most critical types of worldwide change, and most urban areas are experiencing increased growth in population and infrastructure development. Urban change leads to many changes in the daily activities of people living within an affected area. Many studies have suggested that urbanization and crime are related. However, they focused particularly on land uses, t...

Land use/land cover (LULC) has a profound impact on economy, society and environment, especially in rapid developing areas. Rapid and prompt monitoring and predicting of LULC's change are crucial and significant. Currently, integration of Geographical Information System (GIS) and Remote Sensing (RS) methods is one of the most important methods for detecting LULC's change, which includes image p...

Although the mapping of spatiotemporal patterns of urban expansion has been widely studied, relatively little attention has been paid to detailed comparative studies on spatiotemporal patterns of urban growth at the regional level over a relatively longer timeframe. This paper was based on multi-sensor remote sensing image data and employs several landscape metrics and the centroid shift model ...

We examine the joint contribution of urban expansion and climate change on heat stress over the Sydney region. A Regional Climate Model was used to downscale present (1990-2009) and future (2040-2059) simulations from a Global Climate Model. The effects of urban surfaces on local temperature and vapor pressure were included. The role of urban expansion in modulating the climate change signal at...

Urban sprawl is a hot topic of global concern with increasing dramatically and impact on ecological environment. But there is not a mature method to explain the detail of process of urban sprawl and dynamic changes. In this paper, the dynamic changes of urban is studied based on 1980, 1988, 1994, 2000 and 2005 five remote sensing images of Shenzhen. It is distinguished three types including inf...

Nowadays there is a high rate of urban expansion which can not be ignored in proper urban management. Parallel to the urban expansion we are faced with an increase in urban problems, which will lead to complexities dealing with the urban management and planning processes. A city is a set of condensed and broad functionalities which requires handling of huge amount and diverse types of geospatia...

China's extensive urbanization has resulted in a massive loss of natural habitat, which is threatening the nation's biodiversity and socioeconomic sustainability. A timely and accurate understanding of natural habitat loss caused by urban expansion will allow more informed and effective measures to be taken for the conservation of biodiversity. However, the impact of urban expansion on natural ...

urban expansion model (uem) was adapted to simulate urbanization which implements geospatial information systems (gis), artificial neural networks (anns) and remote sensing (rs). two satellite imageries with specific time interval, socio-economic and environmental variables have been employed in order to simulate urban expansion. socio-economic and environmental variables were used as inputs wh...

In this study, we simulated the expansion of the São Paulo Metropolitan Area (SPMA)— the largest metropolitan area in Brazil — by the year 2030 using the Dinamica EGO software with data extracted from Landsat TM 7 (orbit point 219 076, resolution 30 × 30 m). Based on the urban area in 2008, we used an urban growth scenario to analyze urban expansion up to 2030. Subsequently, we used ArcGIS to i...

natural climatic conditions in urban areas can be changed by human physical environment. climate as a natural system and city as a human system have close mutual connections. urban population growth and consequent increase in urban physical expansion may lead to intensification in human activities and disturbances in the environment. this contributes to alterations in solar radiation, balance o...
