A portolan/stac catalog of every known available non-AI generated field boundary.
The agricultural part of the Bulgarian physical block register (физически блокове): a physical block is a contiguous area of land bounded by permanent features, identified as - and classified by its use. The register has been produced from field checks and orthophoto mapping.
These layers hold the blocks used agriculturally — arable land, greenhouses, rice fields and courtyards — where the Physical_Blocks layers of the same service also carry forest, urban and transport land.
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: bg/latest/bg.parquet. All editions together through the S3 glob s3://ftw/harmonized-field-data/bg/year=*/*.parquet (see the AGENTS.md for the DuckDB setup; plain https cannot expand *).
The agricultural part of the physical block register; the same service's Physical_Blocks layers carry forest, urban and transport land as well. The 2021 and 2022 layers are a different release: they carry the usage inside ELGIDENT and publish an area column the later ones do not.
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 Ministry of Agriculture and Food 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 0.2.16:
The conversion is deterministic and lives in fiboa-cli; changes to how a column is mapped are made there, not in this catalog.

geometry | binary | A geometry that reflects the footprint of the field, usually a Polygon. Stored in the source CRS (see proj:code), not reprojected. (spec) |
block_id | string | Field identifier (source column PHBIDENT, per the fiboa data survey) |
bbox | struct<xmin: double, ymin: double, xmax: double, ymax: double> | The bounding box of the field. Per-feature covering column (GeoParquet 1.1), in the source CRS. (spec) |
