Evaluation of Pedestrian-Perceived Comfort on Urban Streets Using Multi-Source Data
Urban street comfort is a crucial measure of street environmental quality. However, traditional evaluations primarily focus on physical elements, often neglecting pedestrian perceptions. In this study, considering five core evaluation dimensions—safety, mobility, aesthetics, perceptibility, and convenience—an innovative quantitative evaluation model is proposed to assess pedestrian-perceived comfort on urban streets by integrating physical enviro…
Relationship between the built environment and urban vitality of Nanjing’s central urban area based on multi-source data
Urban vitality reflects the dynamism, openness, available resources, and linkages between different elements in a city. Many studies have focused on the relationship between urban vitality and the built environment, which can benefit urban planners. Based on multi-source data, this study incorporates the aspects of economy, society, culture, and innovation to comprehensively measure urban vitality. Recognizing the significant influence of the bui…
Spatial Relationship Analysis of Geographic Elements in Sketch Maps at the Meso and Micro Spatial Scales
Sketch maps are an abstract and conceptual expression of humans’ cognition of geographic space. Humans perceive geographical space at different spatial scales. However, few researchers have considered the spatial relationships of geographic elements in sketch maps at multiple spatial scales. Considering the meso and micro spatial scales, this study analyses the accuracy of the spatial relationships depicted in 52 sketch maps of urban areas, inclu…
Extracting Spatio-Temporal Information from Chinese Archaeological Site Text
Archaeological site text is the main carrier of archaeological data at present, which contains rich information. How to efficiently extract useful knowledge from the massive unstructured archaeological site texts is of great significance for the mining and reuse of archaeological information. According to the site information (such as name, location, cultural type, dynasty, etc.) recorded in the Chinese archaeological site text, this paper combin…
A Hierarchical Spatial Network Index for Arbitrarily Distributed Spatial Objects
The range query is one of the most important query types in spatial data processing. Geographic information systems use it to find spatial objects within a user-specified range, and it supports data mining tasks, such as density-based clustering. In many applications, ranges are not computed in unrestricted Euclidean space, but on a network. While the majority of access methods cannot trivially be extended to network space, existing network index…
Uncorrelated Geo-Text Inhibition Method Based on Voronoi K-Order and Spatial Correlations in Web Maps
Unstructured geo-text annotations volunteered by users of web map services enrich the basic geographic data. However, irrelevant geo-texts can be added to the web map, and these geo-texts reduce utility to users. Therefore, this study proposes a method to detect uncorrelated geo-text annotations based on Voronoi k-order neighborhood partition and auto-correlation statistical models. On the basis of the geo-text classification and semantic vector …
