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.

Source code: GitHub repository.

Dataset snapshot

Metric	Value
Polygon rows across regional extracts	1,184,110
Unique polygon identities (osmtype, osmid)	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
Wikipedia + Wikivoyage languages	351
Geographic regions	375
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

[image]

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

Polygon identities with text

[image]

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

H3 text density

[image]

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.
