Building

Inventory of all existing aggregated built elements. Polygons are aggregated without distinction of nature. The buildings are derived from automated processing on the reference layer of the building which can be cut out by architectural nature. Treatment aggregates all adjacent polygons without distinction of nature.现有全部聚合建筑要素清单。多边形聚合过程不区分要素属性。本次数据集所涉及的建筑物源自对建筑参考图层的自动化处理，该参考图层可依据建筑属性进行裁切。该处理流程将所有相邻多边形进行聚合，且不区分要素属性。
