Occupation of the ground by the building in Deux-Sèvre from the Topo database of the IGN

This dataset was made from the 2012 IGN Topo CD (delivered to DDT 79 in 2013). It is therefore the urban task of the building. It has been generated by taking into account various digitised built elements (remarkable construction, industrial construction, undifferentiated buildings, cemeteries, sports grounds, yards, surface constructions, airfields, airfields, processing stations, reservoirs, activity-related surfaces, roadway areas) and sports grounds. This geographic information layer can be juxtaposed to the land cover layer of infrastructure also generated from the IGN Topo BD by DDT 79 (also downloadable under PEGASE).本数据集基于2012版IGN地形数据光盘（IGN Topo CD）制作，该光盘于2013年交付至DDT 79。本数据集聚焦城市建筑相关地理信息处理任务，通过整合各类数字化建筑要素（含标志性建筑、工业建筑、普通建筑、墓地、运动场、庭院、地面构筑物、机场、加工站、水库、作业相关场地及道路区域）生成。该地理信息图层可与基础设施土地覆盖图层叠加使用，后者同样由DDT 79基于IGN地形基础数据库（IGN Topo BD）生成，也可通过PEGASE平台下载。
