Pan-Arctic Building Footprint Atlas v1

The Pan-Arctic Building Footprint Atlas v1 is an open geospatial dataset of harmonized building footprint polygons across the pan-Arctic region, approximately north of 60°N. It provides building geometries together with geometric, source, height, temporal, and functional/occupancy-related attributes where available. The dataset is organized by a 10 × 10 km pan-Arctic grid index and distributed as geographically grouped GeoPackage packages for easier access and reuse. The release includes building footprint packages, grid index files, package manifests, file inventories, MD5 checksums, and a user guide.
