Based on building polygons, we are proposing a GIS(Geographic Information System) and CG integrated system to generate multiple roofed 3-D building models automatically. Building polygons are buildings’ contours on the digital map stored by GIS. A 3-D urban model including 3-D building models is the important information infrastructure that can be utilized in several fields, such as landscape e...

Urban Dynamics modeling needs to implement spatial organization emergence in order to describe the development of services evolution and their usage within spatial centers. In this paper, we propose an extension of the nest building algorithm with multi-center, multi-criteria and adaptive processes. We combine a decentralized approach based on emergent clustering mixed with spatial constraints ...

Object-based image analysis is becoming increasingly popular in classification of very high resolution (VHR) imagery over urban areas. The spectral resolution of VHR imagery (generally they possesses 1 pan and 4 multispectral bands), however, is limited and insufficient for differentiating many urban land cover classes. Due to the spectral similarity of building roofs, roads and parking lots, s...

Finding a method to evaluate people’s emotional responses to urban spaces in a valid and objective way is fundamentally important for urban design practices and related policy making. Analysis of the essential qualities of urban space could be made both more effective and more accurate using innovative information techniques that have become available in the era of big data. This study introduc...

This paper investigates the affect of pathloss and mobility in an urban environment on MANETs. Specifically, this investigation employs mobility and pathloss that resembles the mobility of pedestrians and pathloss in urban environments. We study the behavior of MANETs on a university campus and in the Paddington area of London England. The model utilizes ray tracing to provide realistic radio w...

Lack of education causes and is caused by poverty. In urban areas, it adds to the vulnerability of the poor, resulting in inaccessible schools and irrelevant curricula. Building urban communities and harnessing social capital can create an environment where the poor will have greater opportunities for making decisions that influence their lives. Empowered communities are better able to engage i...

This paper reviews involuntary resettlement resulting from dam-building, which has been ignored relative to the dominant focus of migration research in China, rural to urban migration. Reservoir resettlement in China has a long history, often of misery and hardship for those displaced. Relocatees affected by the Three Gorges Project (1994– 2009) on the Yangtze River face a similar situation. In...

Fine-scale population estimation is essential in emergency response and epidemiological applications as well as urban planning and management. However, representing populations in heterogeneous urban regions with a finer resolution is a challenge. This study aims to obtain fine-scale population distribution based on 3D reconstruction of urban residential buildings with morphological operations ...
