Openaddresses

OpenAddresses is an open-source geospatial data aggregator and directory that collects public domain and open-license address, parcel, and building datasets from governments and organizations worldwide. It functions as a global index and data warehouse for locating and distributing free geospatial records.

The project operates a normalization pipeline that cleans and standardizes diverse source formats into a consistent global coordinate and attribute schema. This process includes a crowdsourced curation pipeline and programmatic quality validation to verify the spatial accuracy and formatting of contributed data.

The platform provides a searchable directory for discovering street centerlines and cadastral footprints, utilizing a standardized spatial index for efficient discovery. Processed records are distributed as compressed flat files to support high-volume downloads and ingestion into geographic information systems.
