Cloud-Optimized Point Cloud (COPC) conversions of publicly-licensed aerial
LiDAR surveys conducted by Hokkaido Prefecture, sourced from geospatial.jp
(G空間情報センター) and the Rakuno Gakuen University-operated ArcGIS Hub
open-data portal. Each published COPC corresponds to exactly one original
.laz file from the surveying agency's own "ORIGINAL" release — files are
never merged, so provenance to the original survey and file remains
traceable.
License and attribution are recorded per survey, not project-wide:
the surveying department (e.g. 総合政策部, 水産林務部) and license terms
(CC-BY in all cases confirmed so far) vary by project. See each asset's
metadata for its specific attribution before reuse. Only surveys with
confirmed license and provenance are published here; others are held back
pending review.
Processing pipeline: optgeo/adopt-hokkaido-lidar.
This product does not host or redistribute the original ZIP/LAZ packages —
only validated COPC derivatives.
