Leaf: Buildings Dataset: GeoDanmark — Geometry
GeoDanmark provides the authoritative building footprint polygons as part of the national topographic dataset. These are photogrammetrically measured outlines.
Spatial Access Path
GeoDanmark.bygning → polygon geometry (direct, no joins needed)
Join to BBR: Match GeoDanmark footprints to BBR buildings via shared spatial location or building identifier to combine attributes + geometry.
Temporal Model
Bitemporal in BBR. GeoDanmark footprints are updated periodically (annual campaign). Historical building states via virkningFra/virkningTil in BBR.
