# OpenPlanetData

> Open, free, and transparent datasets about planet Earth — boundaries, OpenStreetMap snapshots, and time zones — distributed daily as GeoJSON, GeoPackage, and GeoParquet from a global Cloudflare R2 mirror. No API keys, no rate limits.

OpenPlanetData publishes regularly-rebuilt geographic datasets aggregated from authoritative sources (OpenStreetMap, Natural Earth, timezone-boundary-builder, and others). Bulk files are served from `https://download.openplanetdata.com`; the file index is queryable at `https://download.openplanetdata.com/files`.
