South American Rural Cadastral Boundaries

Cadastral parcel boundaries for South American rural land use and supply chain analysis, as cloud-native GeoParquet. Three national collections: Brazil, Paraguay, and Uruguay.

Intended for use alongside Trazo agricultural field boundaries and Fields of The World.

Use case: for parcel-level, multi-parcel analysis — supply chain sourcing, for example — the unique ID column of each cadastral dataset is the most important field. In some cases it is missing.

No collection here has a unique parcel identifier, and the three do not join to each other. Deduplicate before you count, and read the collection README before you join.

Every number on this page was measured over every row of the published file. Nothing here is a sample or an estimate.

License

Each collection declares other, and each links its own terms. Read that link before you redistribute. No SPDX identifier fits any of the three.

An earlier version of this catalog declared CC-BY-4.0 on all three. No upstream source states that. Attribute the producing agency named in each collection's providers. If you need a licence warranty, go to that agency.

Provenance

This catalog is a mirror. None of the three cadastres originate here.

Each collection carries updated, the time its data last reached this bucket. There is no automatic sync. A refresh is a manual re-download and re-upload.

Every collection was reprojected to EPSG:4326 and rewritten as GeoParquet 1.1 with a bbox covering column and ZSTD compression. No row was filtered, and no attribute was renamed or dropped.

The catalog metadata is generated from a repository, linked as rel:vcs on catalog.json. That repository is private, so the link resolves only for people who already have access.

Access

Nothing here needs credentials. Each collection is a single Parquet object served over plain HTTPS with range support, so a query reads only the row groups it needs. There is no partition:glob anywhere in this catalog, so nothing here needs s3://.

Every query above was run against the published files before it was written here, and each one carries the output it produced.

Dataset Composition

brazil-car-area-imovel/brazil_car_area_imovel.parquet

8,453,552 polygons, national coverage, as of 16 July 2026. It replaces the former root-level Brazil_CAR_AREA_IMOVEL.parquet.

Every row carries the single theme Area do Imovel, the property perimeter. CAR also holds theme layers for Permanent Preservation Area, Legal Reserve, Remnant of Native Vegetation, Consolidated Rural Area, Hydrography and others. None of those are in this catalog. They matter for Brazilian rural land use and environmental compliance, and a later release can add them.

Two source records with corrupt coordinates moved, unmodified, into the sidecar brazil-car-area-imovel/brazil_car_area_imovel_suspect.parquet, so no cod_imovel is lost. That sidecar is EPSG:4674, not EPSG:4326.

des_condic gives the administrative status of the submission and has 16 distinct values, not the 10 an earlier version of this page listed. The full table with counts is in the collection README. Use the polygons whatever their status: flag parcels labelled "Cancelado" but do not remove them, especially where no regularized geometry exists in that area. If you omit geometries that are under review, you omit sourcing area.

paraguay-parcelas-activas/paraguay_parcelas_activas.parquet

2,192,890 polygons, downloaded 17 July 2026. The source publishes no capture date for this layer.

dpto is a single-letter department code, not a name. obs is uncontrolled free text carried over from the source registry, and the same text repeats inside clave_comparacion, so a filter on obs alone does not remove it.

uruguay-pais-rural/uruguay_pais_rural.parquet

250,074 polygons, as of 2 February 2025. It replaces the former root-level Uruguay_PaisRural.parquet. AREAHA is an integer, so a parcel under one hectare rounds; AREAMC is a double in square metres.

Older Objects Still Served

Two prefixes under this product predate the catalog and are not part of it:

• temp/ — a Goiás sample CSV and a subset Parquet left from the build
• pageresources/ — the three images this page embeds

pageresources/ is in use. temp/ is referenced by nothing.
