“…Urban compactness is one of the major indicators of sustainable urban development that has been widely used to measure urban forms [54,55]. Meanwhile, fractal dimension can measure the degree of irregularity of urban land uses [56].…”

Abstract:The urban clusters in the Middle Reaches of the Yangtze River (MRYR) in China include the Chang-Zhu-Tan urban agglomeration, the Wuhan metropolitan area, and the Poyang Lake urban agglomeration. While previous studies of urban expansion in China focused mainly on the coastal regions, this study aimed to investigate urban expansion patterns and factors in the MRYR, which are crucial for urban development in Central China. A neighborhood statistics analysis (NSA) method and a local-optimized threshold method were used to detect urban changes during 1992-2011 from the time-series Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) nighttime light (NTL) images. The evolution of urban expansion intensity and landscape metrics were analyzed at multiple spatial scales, including the whole region, urban agglomeration, and city scales. Finally, the expanded STochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) model was built to explore the factors that controlled NTL intensity. The results revealed that urban areas extracted from the NTL data were consistent with those extracted from the Landsat Thematic Mapper data, with an overall accuracy of 81.74% and a Kappa of 0.40. A relatively slow urbanization pace was observed from 1992 to 2002 in the MRYR region, which then accelerated in the period of 2002 to 2007 and then slowed down between 2007 and 2011. Additionally, urban expansion exhibited a radial pattern. The results further indicated that major factors controlling NTL intensity were gross domestic product, followed by total investment in fixed assets, tertiary industry, urban construction area, non-agricultural population, and industrial output in the city clusters. The study provides important insights for further studies on the urbanization processes in the MRYR region.

“…The metrics developed are partly derived from geometric properties also applied elsewhere in landscape ecology [19] and that have shown potential for analysing urban morphology [20][21][22][23][24]. We complement these geometric-based metrics by a series of alignment, continuity and symmetry indices that reveal some additional properties of the urban layout.…”

It has been long recognised that the underlying spatial structure plays an important role when navigating in urban environments. However, the modelling of the forms and properties that emerge from the city is still a difficult issue to address. The objective of the research developed in this paper is to study and represent two important qualities of urban environments as identified by Lynch and Bentley in their respective seminal works, that is, legibility and permeability. Our objective is to identify and implement a series of metrics applied to the layout of a given city that reflects these concepts of legibility, and then to evaluate to which degree these measures are correlated to different human perceptions of the city, particularly differences between humans who have or have not had an experience of a given urban environment. The whole approach is applied to the context of a neighbourhood of the city of Tehran in Iran. The findings show that permeability match relatively well with residents' evaluations while legibility rather complies with newcomers' evaluations.

“…Urban growth studies have been attempted in several developed countries (Hu et al, 2003;Radhakrishnan et al, 2014;Sudhira et al, 2004;Triantakonstantis and Stathakis, 2015). These are some examples and similar applications also exist for other countries like China (Yu and Ng, 2007;Weng, 2001;Xiao et al, 2006) and India (Rahman et al, 2011;Taubenbock et al, 2009 The study was conducted to analyze the dynamics of urban sprawl by using the remote sensing and GIS techniques.…”

Over the past 30 years, Land development and consumption have been out of control and expanding out of order, especially to marginal areas of some metropolises in Pakistan. In this research, the dynamic change of urban sprawl and its spatial and temporal characteristics was analyzed for Karachi division, Pakistan. To achieve the goal different image processing techniques were applied i.e., (i) Supervised, (ii) Unsupervised image classification and (iii) Normalized Difference Built-Up Index on Landsat imageries for the years 1991, 2000 and 2013. Unsupervised classification technique was proved to be more effective with an overall agreement of 81%. The study concluded that from 1991-2000, the urbanization in Karachi was increased from 486-729.2 km 2 , whereas from 2000-2013 the urbanization was almost double i.e., 1582.5 km 2 . Apart from the derived results, this study also proved the potentials of remote sensing data and effectiveness of demonstrated/proposed techniques in urban geographic studies.
