The latest edition is also available at a stable path: de_bb_block/latest/de_bb_block.parquet. All editions together through the S3 glob s3://ftw/harmonized-field-data/de_bb_block/year=*/*.parquet (see the AGENTS.md for the DuckDB setup; plain https cannot expand *).

Columns

`id`	string	An identifier for the field. (spec)
`collection`	string	The identifier of the collection. (spec)
`hbn`	string	Carried over from the source column `HBN_KAT`; the publisher documents no meaning for it.
`net_area`	float	Carried over from the source column `FL_NETTO`; the publisher documents no meaning for it.
`metrics:area`	float	Area of the field, in square meters (m²). Must be > 0 and <= 1,000,000,000. (spec)
`flik`	string	The area identifier (FLIK code) is a 16-character string. (spec)
`kreis_nr`	uint16	Carried over from the source column `KREIS_NR`; the publisher documents no meaning for it.

`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)

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):

Provenance

This catalog is a mirror: the data is produced and licensed by Land Brandenburg 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:

2026: converted 2026-08-22 from https://data.geobasis-bb.de/geofachdaten/Landwirtschaft/dfbk.zip

The conversion is deterministic and lives in fiboa-cli; changes to how a column is mapped are made there, not in this catalog.
