Overture Maps Foundation
Overture Maps Foundation is a Linux Foundation collaborative project that produces free, open, and interoperable map data. Overture publishes cloud-native GeoParquet datasets, on a regular release cadence, across six themes - Addresses, Base, Buildings, Divisions, Places, and Transportation - governed by a common conflation pipeline and an open schema. Rather than a hosted REST API, Overture distributes data through Amazon S3 and Microsoft Azure (and via partner mirrors on BigQuery, Snowflake, Databricks, Fused, Wherobots), and provides an open Python CLI, a tile generator, and an Explorer site for developers. Founding members include Amazon, Meta, Microsoft, and TomTom.
Overture Maps Foundation publishes 11 APIs on the APIs.io network. Tagged areas include Maps, Geospatial, Open Data, GeoParquet, and Open Source.
Overture Maps Foundation’s developer surface includes documentation, GitHub presence, and 5 more developer resources.
