About the project

What is AnythingPOI?

AnythingPOI is an open-pipeline project that fuses point-of-interest records from OpenStreetMap and the Overture Maps Foundation into a single, clean, deduplicated dataset. Each record carries a confidence score derived from source overlap, attribute richness, and spatial uniqueness.

The project is reproducible: the full pipeline — ingestion, conflation, scoring, and tile generation — runs from open source code and public data. No proprietary services. No API keys for the core data.

How it works

Ingest

OSM PBF files are downloaded from Geofabrik and parsed with PyOsmium. Overture Maps data is queried via DuckDB directly from the S3 release.

PyOsmium DuckDB Geofabrik

Conflate

POIs are spatially indexed using H3 resolution-11 hexagons (~24 m edge). Candidates are matched on category agreement and Jaro–Winkler name similarity.

Score

Each POI receives a confidence score (0.01–0.99). Positive signals include dual-source verification, Wikidata linkage, and contact data richness.

Tile

Output is written as PMTiles v3 (zoom 4–16) and Cloud-Optimised GeoParquet partitioned by Tier-1 category for downstream use.
