Cores, ribbons, scattered buildings in Flanders – state 2019

This map shows a typological classification of the building in Flanders, dividing it into cores, ribbons and scattered buildings. This classification is based on a maximum morphological approach. This contrasts with a policy delineation, such as, for example, the legally defined boundaries of areas through spatial implementation plans, or a delineation that takes significant account of the level of activity, such as, for example, the classification into urban, peri-urban and rural areas (Poelmans et al., 2020). This classification is fully automatic using an algorithm specifically developed for this purpose based on a number of spatial variables. It built on the methodology developed in previous studies that sought to map in detail lint and core construction. The algorithm used was adjusted during interactive working sessions with experts from VITO and the Environment Department. As a result, the following geodata layers were created: a polygonne layer with the cores as contiguous built-up areas with a total size of at least 5 ha and housing a total of at least 20 families, and with a sufficiently high density of buildings (number > 30 buildings within a radius of 100 m), or a sufficiently high surface area (footprint > 9 500 m² within a radius of 100 m) to buildings or a sufficiently high density of households (number of > 60 households within a radius of 100 m), a line layer with ribbons consisting of streets located outside the core, which are built for a minimum of 200 m contiguous or of which at least 80 % of the total street length is built on a polygonne layer, and all of these sites are not listed as a polygonne layer with scattered buildings. The large-scale reference file (GRB) was used as the source of the buildings and administrative parcels. The Road Register was used for the roads. The land take was made using the same name indicator published by the Department of Environment. For household density inside the cores, the same name indicator was used as published by the Department of Environment. The military areas are those legally defined by the regional plans. The business parks are based on the GIS business parks of the Flemish Agency for Innovation and Entrepreneurship (VLAIO). The camping and holiday areas come from the Biological Validation Card (BWK) and the RuiTeR database of Toerisme Vlaanderen. More details on the method used for this typological classification can be found in the technical report: ‘Tomas Crols, Lien Poelmans, Lorenz Hambsch, Stijn Vanacker, Peter Willems, Ann Pisman, Karolien Vermeiren and Joris Pieters (2021), Kernen, linten, scattered building in Flanders, state 2013-2016-2019. Morphological classification of building in Flanders ", which you can find at https://archief.onderzoek.omgeving.vlaanderen.be/Onderzoek-2825095本地图展示了佛兰德斯地区建筑的形态学分类体系（typological classification），将其划分为核心建成区、带状建成区与零散建筑三类。该分类基于最大形态学方法（maximum morphological approach），与政策划定的边界形成显著差异：一类是通过空间实施计划（spatial implementation plans）依法界定的区域边界，另一类是将活动层级作为核心考量因素的划分方式，例如划分为城市、城郊与乡村区域（Poelmans等，2020）。 本次分类完全依托专为该任务开发的算法实现全自动处理，算法基于一系列空间变量构建。其研究基础为既往研究中用于精细绘制线状与核心建成区的方法体系，并在与弗拉芒技术研究院（VITO）及环境部门专家的交互工作会议中完成了算法优化调整。 经上述流程，最终生成以下三类地理数据图层（geodata layers）： 1. 核心建成区面状图层（polygonne layer）：指满足以下任一条件的连片建成区域，总面积不小于5公顷且至少容纳20户家庭，同时需符合下列密度或规模要求之一：建筑密度足够高（100米半径范围内建筑数量大于30栋）、建筑基底总面积（footprint）足够大（100米半径范围内建筑基底总面积大于9500平方米），或住户密度足够高（100米半径范围内住户数量大于60户）； 2. 带状建成区线状图层（line layer）：指位于核心建成区之外的街道，需满足以下任一条件：连续建成长度不小于200米，或街道总长度中至少80%的路段对应的建筑已纳入上述面状图层范围，且该区域未被归类为零散建筑面状图层。 本数据集的建筑与行政地块数据源为大型参考文件（GRB），道路数据来源于道路登记册。土地开发数据采用环境部门发布的同名指标；核心建成区内的住户密度数据同样采用环境部门发布的同名指标。军事区域为区域规划依法划定的范围；产业园区数据基于弗拉芒创新与创业署（VLAIO）的GIS产业园区图层；露营与度假区域数据来源于生物验证卡（Biological Validation Card, BWK）以及佛兰德斯旅游局（Toerisme Vlaanderen）的RuiTeR数据库。 关于本次形态学分类所采用方法的更多细节，可参阅技术报告：《Tomas Crols、Lien Poelmans、Lorenz Hambsch、Stijn Vanacker、Peter Willems、Ann Pisman、Karolien Vermeiren 与 Joris Pieters (2021), 佛兰德斯地区核心区、带状区与零散建筑：2013-2016-2019年建筑形态学分类》，获取链接：https://archief.onderzoek.omgeving.vlaanderen.be/Onderzoek-2825095
