构成城市的构件的空间布局对于理解指导城市动态的规则很重要。我们的研究根据其形式和功能将国家开源空间分类的发展概述为单一类型。我们创建一个定制的粒度空间单元,封闭的镶嵌,并测量在相关空间上下文中捕获其形式和功能的字符。使用单个封闭镶嵌单元的 K 均值聚类,我们生成了整个英国的空间分类。属于同一类的连续封闭镶嵌单元被合并,形成空间特征几何形状及其类型。我们根据区域重要性确定了 16 种不同类型的空间特征,从野生乡村、各种郊区到表示城市中心的类型。这里介绍的开放数据产品有可能为其他对城市环境感兴趣的研究人员和寻求对城市及其结构的独特视角的政策制定者提供边界划分。
The spatial arrangement of the building blocks that make up cities matters to understand the rules directing their dynamics. Our study outlines the development of the national open-source classification of space according to its form and function into a single typology. We create a bespoke granular spatial unit, the enclosed tessellation, and measure characters capturing its form and function within a relevant spatial context. Using K-Means clustering of individual enclosed tessellation cells, we generate a classification of space for the whole of Great Britain. Contiguous enclosed tessellation cells belonging to the same class are merged forming spatial signature geometries and their typology. We identify 16 distinct types of spatial signatures stretching from wild countryside, through various kinds of suburbia to types denoting urban centres according to their regional importance. The open data product presented here has the potential to serve as boundary delineation for other researchers interested in urban environments and policymakers looking for a unique perspective on cities and their structure.
