Geographic coverage

OSM polygon density

Each colored H3 cell contains the raw count of finalized polygons rows whose geometry centroid falls inside the cell. Every polygon row contributes exactly once, computed from its Shapely geometry centroid in CRS84 (not its bounding-box midpoint). The map is built at H3 resolution 3. Overlapping Geofabrik extracts are intentionally preserved as separate observations, so two shards covering the same OSM feature will count it twice. The colour scale is logarithmic (magma); raw counts per-cell range from 1 to 8,754 across 2,937 H3 cells, with 290,922 finalized polygon rows from 280 shard(s). The image_assets configuration is not separately counted in this map.

Schema

Rows include OSM type/ID/version/changeset/timestamp, source PBF identity, full OGC:CRS84 WKB geometry, geodesic area_m2, bounds, every original OSM tag, and the exact raw image, wikimedia_commons, mapillary, panoramax, panoramax_values, kartaview, flickr, and bubbleid values.

The image_assets configuration is one-to-many. Join it to polygons with osm_type, osm_id, osm_version, and source_pbf. Asset rows preserve the exact source key/value, canonical provider reference, resolution status, page URL, direct image URL when returned, expiry, MIME type, dimensions, and structured license/author metadata when available.

Limitations and intended use

References and resolved URLs may be stale, inaccessible, provider-specific, or unrelated to the current feature. Inclusion does not establish image copyright, licensing, safety, availability, or correspondence to the mapped feature. Wikimedia Commons category membership does not prove depiction of the polygon; it is labeled as category_membership. No image body is downloaded.

Overlapping Geofabrik extracts are intentionally preserved as separate observations and quantified above. Statistics in this card are generated only from finalized manifests and their size-checked GeoParquet and asset shards. The geographic coverage map references Natural Earth 1:110m landmass data (public domain) for context only.
