Taking almost all cities in China(including Hong Kong and Macau) as the research object in the year 1990, 2000 and 2007, this article studies the urban spheres of influence by using gravity model. Based on overall grasp of the spatial pattern of Chinese urban spheres of influence, the spatial characteristics of urban agglomerations are paid close attention to. Urban agglomerations are national ...

Unprecedented growth of urban population presents a major challenge for sustainable economic growth. The State of Punjab which was known for its agricultural performance and dynamic rural economy upto 1990s is now emerging as a service economy dominated by urban sector. The State of Punjab has emerged as the sixth major urbanised State in India. According to the 2011 census 37.49 per cent of th...

Urban growth and land use change models are an important and innovative tool that support planning and development of sustainable urban areas. The data requirements for parameterization, calibration and validation of urban models are intense due to the complexity of the models and their objectives. In this study several urban land use change models are evaluated and their demands on spatial dat...

BACKGROUND With more than half of Africa's population expected to live in urban settlements by 2030, the burden of malaria among urban populations in Africa continues to rise with an increasing number of people at risk of infection. However, malaria intervention across Africa remains focused on rural, highly endemic communities with far fewer strategic policy directions for the control of malar...

BACKGROUND Health care accessibility is known to differ geographically. With this study we focused on analysing accessibility of general and specialized obstetric units in England and Germany with regard to urbanity, area deprivation and neonatal outcome using routine data. METHODS We used a floating catchment area method to measure obstetric care accessibility, the degree of urbanization (DE...

Stormwater management using water sensitive urban design is expected to be part of future drainage systems. This paper aims to model the combination of local retention units, such as soakaways, with subsurface detention units. Soakaways are employed to reduce (by storage and infiltration) peak and volume stormwater runoff; however, large retention volumes are required for a significant peak red...

Urban traffic management problems have taken an important place in most of transportation research fields, hence the emergence of vehicular ad-hoc network (VANET) as an essential part of the intelligent transportation system ITS, that intervenes to improve and facilitate traffic management also control as far as improve global driving experience in the future. Indeed the concept of smart city o...

As a vital indicator for measuring urban development, urban areas are expected to be identified explicitly and conveniently with widely available dataset thereby benefiting the planning decisions and relevant urban studies. Existing approaches to identify urban areas normally based on midresolution sensing dataset, socioeconomic information (e.g. population density) generally associate with low...

Modelling urban dynamics is mostly pronounced in metropolitan areas, where spatial information science could contribute to efforts of understanding the pattern and future characteristics. This paper discusses the past, current and future trend of land-use dynamics of European part of the Istanbul Metropolitan. Studies on urban growth modelling state that, there is no consensus on the selection ...
