In recent years, settlements have sprawled beyond the urban growth boundaries, due to a number of factors, including mobility, technology, and blight. As result, governments globally opted restructure their local administrative boundaries (municipalities) be more accommodating unplanned growth, while setting clear limit extent which region could grow. Without boundary, problems such as civil co...

almost all countries have faced the urbanization. in the long run, changes in the production technology have caused migration from rural to urban areas. existing cities have grown and new ones have been created. this is named as “urban development” in the urban literature. cites are created because of economies of scale in production and consumption. there are different cities with different si...

This paper analyzes characteristics, major driving forces and alternative management measures of land-use change in Kunshan, Jiangsu province, China. The study used remote sensing (RS) maps and socio-economic data. Based on RS-derived maps, two change matrices were constructed for detecting land-use change between 1987 and 1994, and between 1994 and 2000 through pixel-to-pixel comparisons. The ...

Reasonable delineation of the urban growth boundary (UGB) plays a vital role in guiding orderly space and ensuring environmental health. Existing methodologies for UGB have failed to address significance ecological security. Therefore, this study presents framework that couples security pattern (ESP) establishment construction land expansion (CLE) simulation delineate UGB. The proposed is appli...

Urban environment has functioned not only for ecological reason but also for socioeconomic function, due to this reason extraction of urban vegetation in highly dense urban environment becomes more important to understand the inhabitants’ satisfaction of urban green space. With a medium resolution of satellite imagery, the precision is very low. We used high resolution of WorldView-2 satellite ...

Nocturnal cooling of urban areas governs the evolution of thermal state and many thermal-driven environmental issues in cities, especially those suffer strong urban heat island (UHI) effect. Advances in the fundamental understanding of the underlying physics of nighttime UHI involve disentangling complex contributing effects and remains an open challenge. In this study, we develop new numerical...

Urbanization is found to be closely associated with land use/land cover change which has an important influence in our environment and ecosystems, such as urban heat island effect, biodiversity loss, soil erosion, and pollutions. Studies on accurately simulating urban expansion have been inspired by increasing concerns of the sustainability of urban development. This paper reports our research ...

Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...

Urban growth is a process that imposes profound physical and socioeconomic restructuring on cities. Urban land expansion as an immediate physical manifestation of urban growth has been extensively studied using a variety of remote sensing methods. However, little research addresses the interactions between urban land expansion and corresponding activity changes, especially at local scales. We p...
