简介：​To accurately estimate leaf area index (LAI) in mangrove areas, the selection of appropriate models and predictor variables is critical. However, there is a major challenge in quantifying and mapping LAI using multi-spectral sensors due to the saturation effects of traditional vegetation indices (VIs) for mangrove forests. WorldView-2 (WV2) imagery has proven to be effective to estimate LAI o...

简介：​Extensive research has focused on modelling and analysis of urban flooding in relatively small catchments. Find-ings in small areas tend to be site-specific, and may not be applicable to larger study areas. Larger scale studies can identify general patterns and influential factors; however, few studies have investigated urban flooding on a larg-er scale such as a metropolitan area. In this st...

简介：​Research on journey-to-crime distance has revealed the importance of both the characteristics of the offender as well as those of target communities. However, the effect of the home community has so far been ignored. Besides, almost all journey-to-crime studies were done in Western societies, and little is known about how the distinct features of communities in major Chinese cities shape resi...

简介：​Few studies conduct a quantitative assessment between the urban extent and local precipitation characteristics. In this paper, high-resolution precipitation data and urban extent data are used to investigate the correlation between precipitation fre-quency, intensity and extremes and urban extent under different climate conditions over the Pearl River Delta, China. Analysis reveals that extre...

简介：​The literature shows that offenders’ subsequent crime location choices are affected by their prior crime location choices. However, the published studies have focused on the influence of time and place of a previous crime, without testing the impact of whether the offender was arrested during the act of the prior crime. On the basis of the literature, this study further examines the influenc...

简介：​Residential location of offenders has been an important topic in the crime literature. However, prior research on offender residence pays little attention to the factor of age. Coupled with the rapid urbanization in China, many Chinese have moved from rural areas to urban areas and many burglaries are committed by these migrants, especially adult migrants. They need to choose their residences...

简介：​Urban planning and management need accurate three-dimensional (3D) data such as light detection and ranging (LiDAR) point clouds. The mobile laser scanning (MLS) data, with up to millimeter-level accuracy and point density of a few thousand points/m2, have gained increasing attention in urban applications. Substantial research has been conducted in the past decade. This paper conducted a comp...

简介：​Mangrove forests are important constitutions for sustainable develop-ment of coastal ecosystems, and they are often mapped and monitored with remote sensing approaches. Satellite images allow detailed stu-dies of the distribution and composition of mangrove forests, and therefore facilitate the management and conservation of the ecosys-tems. The combination of multiple types of satellite imag...

简介：​Previous behavioral studies on urban structure have been limited by the scale, accuracy, or promptness in obtaining statistical data used for delimiting retail center boundaries and hierarchical analysis. Using a large amount of GPS-enabled taxi data from Guangzhou, China, this research attempts to delimit the boundaries of retailing centers and explore their hierarchical characteristics. The...

简介：​Immigrants and natives are generally comparable in committing violent crimes in many Western cities. However, little is known about spatial differences between internal migrant offenders and native offenders in committing violence in contemporary urban China. To address this gap, this research aims to explore spatial variation in violent crimes committed by migrant and native offenders, and e...

简介：​Insufficient network capacity and conflicts between pedestrians and vehicles at roadway intersections can be critical obstacles to the operational efficiency of evacuation activities. Reducing pedestrian—vehicle conflict points and expanding net-work capacities are two possible approaches to improving oper-ational efficiency, especially when network accessibility varies in different evacuati...

简介：​Both rural to urban migration and urban crime are well researched topics in China. But few studies have attempted to explore the possible relationships between the two. Using calls for service data of ZG city in 2014, the Sixth Census data in 2010, this study examines relationships between migrants and crime by using structural equation models. Two hypotheses were tested: (1) the distribution...

简介：​Coastal areas are usually densely populated, economically developed, ecologically dense, and subject to a phenomenon that is becoming increasingly serious, land subsidence. Land subsidence can accelerate the increase in relative sea level, lead to a series of potential hazards, and threaten the stability of the ecological environment and human lives. In this paper, we adopted two commonly use...

简介：Negative binomial (NB) regression model has been used to analyze crime in previous studies. The disadvantage of the NB model is that it cannot deal with spatial effects. Therefore, spatial regression models, such as the geographically weighted Poisson regression (GWPR) model, were introduced to address spatial heterogeneity in crime analysis. However, GWPR could not account for overdispersion, ...
