Harmonized Field Boundary Data

Official, non-AI field boundary datasets — typically published by governments from their agricultural subsidy registers (IACS/LPIS), cadastres and statistics — harmonized into the fiboa schema with fiboa-cli and republished as cloud-native GeoParquet and PMTiles. 51 collections (AT, BE, CH, CZ, DE, DK, EC, EE, ES, FI, FR, HR, IE, IT, JP, LT, LU, LV, NL, NZ, PT, SI, SK, US), 123,939,996 fields in their latest editions. Each collection is one source dataset, partitioned by edition year; s3://ftw/harmonized-field-data/*/latest/*.parquet reads the newest edition of every collection (S3 through the Source Cooperative proxy, see the agent guide). Hosted by Fields of the World on Source Cooperative; the metadata is maintained in the harmonized-field-data-catalog repository, where corrections are welcome as pull requests.

Collections

Access

Everything is static files on object storage: query them in place with DuckDB, GeoPandas or any GeoParquet reader, and render the PMTiles with MapLibre. Single files are plain https URLs; globs use the S3 form of the same prefix through the Source Cooperative proxy (s3://ftw/harmonized-field-data, endpoint https://data.source.coop, anonymous), because * needs a listing that https does not provide. Newest edition of every collection:

License

Each collection carries the license of its source data provider (see the table and each collection.json). The catalog metadata, styles and tooling are Apache-2.0, in the repository.

Provenance

A mirror: every collection links its original source (rel: via) and the fiboa data survey entry describing it, and records the fiboa-cli version that converted it. Conversion logic lives in fiboa-cli; this repository only orchestrates publication. Previously published at source.coop/fiboa/data.
