Buildings Modelling: Level of Detail 2
Roof shapes are the most significant improvement for LoD 2 buildings compared to LoD 1. Data represent 3D building shapes, including complex architectural forms: sloping roofs, roof furniture, elevator shafts, towers, and spires.
LoDs 2.0 and 2.1 building models are produced for various tasks of environmental management like solar energy assessment, GIS and architecture projects, 3D visualization of cities, and developed in multiple GIS formats (Rhino, ArcGIS, Autocad dwg, Sketchup skp, fbx, obj etc.). The parameters of azimuth, tilt angle, area of flat parts, and roof height can be calculated and assigned for each roof element.
