Map Viewing Service (WMS) of the dataset: Building of the Puy of Dome — internal layer DDT

Layer resulting from a cross between the geographical data of the PCI downloadable from cadastre.data.gouv.fr and the data holders of the land files accessible via CEREMA — Each building is characterised in particular by its function (individual housing, collective housing, area of activity, dependency) and by its year of construction its aim is to be as comprehensive as possible; the buildings were merged to the plot and aggregated majic data本数据集图层由两类地理数据交叉融合生成：一类为可从cadastre.data.gouv.fr下载的PCI地理数据，另一类为可通过CEREMA获取的土地档案持有方提供的数据。每栋建筑的核心特征包括其功能属性（独栋住宅、集合住宅、产业活动区域、附属用房）与建造年份。该数据集旨在实现最大程度的全面性，已将建筑数据与宗地完成空间合并，并聚合了majic（MAJIC）数据。
