OSM Polygon Wikidata, Wikipedia and Wikivoyage

OSM polygons carrying wikidata=*, enriched with multilingual Wikipedia and Wikivoyage documents. The published tables preserve regional records and provenance.

Metric	Value
Polygon rows across regional extracts	1,184,110
Unique polygon identities (osm_type, osm_id)	1,157,841
Polygons with successful non-empty text (unique OSM identities)	650,663
Wikipedia + Wikivoyage documents	2,206,563
Wikipedia + Wikivoyage sections	12,299,365

Total Parquet size	20.6 GB

Polygon rows preserve regional records. Identity metrics use one deterministic representative per (osm_type, osm_id). Text requires fetch_status=ok and a trimmed non-empty full_text.

Text volume: 801,528,334 document words. Sentence rows are not generated for this dataset version.

Document words count full Wikipedia and Wikivoyage document text; section rows are excluded. Sentence rows include split and explicitly unsplit unsupported-language rows when sentence sidecars exist.

Coverage maps

All polygon identities

One point per unique retained polygon identity, including identities without text.

Polygon identities with text

One point per unique identity with successful non-empty text (650,663).

H3 text density

Each H3 cell shows the absolute count of unique text-covered polygon identities; it is not a proportion.

Geographic distribution by continent

Counts use one deterministic representative per polygon identity and the same text definition as the maps.
