“…However, the existence of these temporary buildings not only affects the cityscape but also poses safety risks such as fire and collapse. Therefore, it is very important to detect its evolving characteristics and analyze its impacts [15]. Based on multi-temporal data from 2013 to 2021, this study employs various spatiotemporal analysis methods to focus on the spatiotemporal evolution characteristics and patterns of the color steel building clusters in Lanzhou City, including overall features, centroid deviations, and clustering degrees.…”

With the continuous acceleration of China’s urbanization process, color steel plate, as a new type of building material, has been widely used in all kinds of temporary buildings and has become the spatial carrier of the specific development stage of urbanization. This study focuses on Lanzhou City as a case study to deeply analyze the spatiotemporal distribution and evolution of color steel plate buildings. Utilizing data extracted from Google imagery and GF-2 satellite images of the built-up areas in Lanzhou, spatial statistical and analytical methods such as centroid analysis, compactness index, and patch density are applied. Systematic analysis is conducted across different time periods and spatial scales to examine the evolution of indicators, including quantity, centroid distribution, spatial clustering, and distribution direction. The results show that from 2013 to 2021, the prevalence of color steel buildings in Lanzhou city initially increased and then decreased, and the number peaked in 2017, but there is a significant difference between distinct areas in the urban area. By quantitatively analyzing the spatial and temporal evolution characteristics of color steel plate buildings, this study reveals the important role it plays in promoting the urbanization process and provides a scientific basis for relevant planning decisions.

“…Urban villages are commonly found across Chinese cities and provide affordable housing for a large population of migrant workers [4], possessing unique spatial properties and social roles [3]. Therefore, the scientific and rational approach to the renovation and reconstruction of urban villages is closely related to national welfare and people's livelihoods, and it constitutes a pressing issue that needs to be addressed in the process of urban development [5,6].…”

Urban villages represent informal residential areas emerging since China’s rapid urbanization process. Scientific map generalization of urban villages with scientific maps aids readers in discerning their distribution and making informed decisions concerning them. However, there is still a scarcity of research on the automatic extraction and generalization of urban villages from vector data, which needs to be studied to further improve the expression of maps. To address this problem, this paper presents a methodology for the extraction and generalization of urban villages from Digital Line Graphics. Firstly, a heuristic approach is employed to analyze the atypical morphological characteristics of urban villages. Then, indices based on computational geometry and the modified Hausdorff distance are utilized to quantify these traits. Lastly, an automatic generalization principle for urban villages is offered. The approach was tested in experimental blocks and proved to be effective. It offers a novel method for the automatic extraction and cartography of urban villages.
