Fractal dimension analysis of spatial distribution rationality of urban fire stations
Fire stations are critical urban public infrastructures, and their spatial distribution should align with the spatial patterns of urban buildings to ensure efficient service delivery. Evaluating the rationality of fire station distributions requires appropriate methods, yet conventional spatial analysis approaches rely on characteristic scales that fail to capture the scale-free nature of urban forms. This study employs fractal geometry to analyz…
Euclidean–Fractal Measures of Spatial–Temporal Urban Form and Growth with Data Fusion
This research presents a comprehensive spatial–temporal analysis of urban form and growth in Charlotte and Mecklenburg County, North Carolina, USA, from 1900 to 2017 at the land parcel level. Employing a data fusion framework, we integrate diverse datasets—including historical cadastral records, census data, remote sensing imagery, and infrastructure maps—to examine urban morphology through Euclidean and fractal geometries. Urban growth was recon…
Multifractal scaling analyses of the spatial diffusion pattern of Covid-19 pandemic in Chinese mainland
Revealing spatio-temporal evolution regularity in the spatial diffusion of epidemics is helpful for preventing and controlling the spread of epidemics. Based on the real-time COVID-19 datasets by prefecture-level cities, this paper is devoted to exploring the multifractal scaling in spatial diffusion pattern of COVID-19 pandemic and its evolution characteristics in Chinese mainland. The ArcGIS technology and box-counting method are employed to ex…
Defining urban boundaries by characteristic scales
Characteristic Scales, Scaling, and Geospatial Analysis
Les phénomènes géographiques s’inscrivent dans deux catégories : les phénomènes dépendants d’échelle et les phénomènes invariants d’échelle. Les premiers ont des échelles caractéristiques, ce qui n’est pas le cas des seconds. Les méthodes quantitatives et mathématiques classiques ne peuvent être appliquées efficacement aux phénomènes géographiques dépendants d’échelle. L’auteur compare les systèmes géographiques dépendants d’échelle et invariants…
Fractal-Based Modeling and Spatial Analysis of Urban Form and Growth
Fractal dimension curves of urban growth can be modeled with sigmoid functions, including logistic function and quadratic logistic function. Different types of logistic functions indicate different spatial dynamics. The fractal dimension curves of urban growth in Western countries follow the common logistic function, while the fractal dimension growth curves of cities in northern China follow the quadratic logistic function. Now, we want to inves…
