INSPIRE - Annex III Theme Buildings - Building 3D - 2020

This dataset contains the buildings in 3D on the national territory of the Grand Duchy of Luxembourg except the city of Luxembourg. The 3D buildings were made based on the aerial shots of summer 2020 (flight period: end of July, beginning of August and mid-September 2020; flight height: +/- 3500 m above the ground) by photogrammetric rendering of the roofs (QME in x, y and z ≤ 20 cm), followed by downward extrusion and texturing of the resulting 3D models of the buildings with the oblique shots. Only the roofs of buildings with a footprint greater than 20 m2 were entered, taking into account superstructures (e.g. dog-sitting) whose longest side exceeds 50 cm and which have a volume greater than 1 m3. The 3D buildings correspond to the LOD (Level of Detail) 2.2 classification. This dataset has been harmonized according to the INSPIRE theme "Buildings" data specification.

本数据集收录了卢森堡大公国领土上除卢森堡市外的三维建筑模型。这些三维建筑模型基于2020年夏季的航空摄影（飞行周期：7月底至8月初及9月中旬；飞行高度：地面以上±3500米），通过摄影测量渲染屋顶（QME在x、y和z方向上的精度≤20厘米）制成，随后利用斜向摄影对生成的三维建筑模型进行向下挤压和纹理处理。仅收录基底面积超过20平方米的建筑物屋顶，并考虑超结构（例如犬舍）等，其最长边超过50厘米且体积大于1立方米的结构。三维建筑模型对应于LOD（细节级别）2.2分类。本数据集已根据INSPIRE主题“建筑”数据规范进行标准化。描述信息来源于catalog.inspire.geoportail.lu。
