A portolan/stac catalog of every known available non-AI generated field boundary.
The Finnish Food Authority (FFA) since 2020 produces spatial data sets, more specifically in this context the "Field parcel register" and "Agricultural parcel containing spatial data". A set called "Agricultural land: arable land, permanent grassland or permanent crop (land use)".
Browse this collection in the data browser, or start from the AGENTS.md for tested queries.
The latest edition is also available at a stable path: fi/latest/fi.parquet. All editions together through the S3 glob s3://ftw/harmonized-field-data/fi/year=*/*.parquet (see the AGENTS.md for the DuckDB setup; plain https cannot expand *).
Properties that are the same for every field are stored once, in the GeoParquet file's collection metadata rather than as columns (latest edition shown; a client reading only the table will not see them):

This catalog is a mirror: the data is produced and licensed by Finnish Food Authority and republished here as cloud-native GeoParquet and PMTiles by Fields of the World. Each edition was downloaded from the source and converted with fiboa-cli 0.21.0, vecorel-cli 0.2.15:
The conversion is deterministic and lives in fiboa-cli; changes to how a column is mapped are made there, not in this catalog.
