Cadastral boundary data for select countries
Every claim here is quoted from a source or measured from the data. The measured values below came from queries over all 2,192,890 rows of the published file, run in August 2026.

GeoParquet 1.1.0, EPSG:4326, WKB, geometry types Polygon and MultiPolygon,
bbox covering column present, ZSTD, 44 row groups, largest 50,000 rows,
smallest 42,890. Parquet format version 2. 227,046,889 bytes.
No column identifies a row. See the counts above. Every candidate key
repeats. A join fans out, and COUNT(*) counts geometries, not parcels.
dpto is a single letter, not a name or a number. There is no
department-name column in this file. Map the letters yourself against a
Paraguayan department list, and state the mapping you used.
dist is an int64 but padron, zona, mz, lote and finca are
double. They are identifiers stored as floating point. Cast before you
compare or format, or 577 prints as 577.0 and equality against an integer
fails.
obs is uncontrolled free text, and clave_comparacion repeats it.
886,763 of 2,192,890 rows have a non-blank obs. In 822,579 rows the same
text is the last pipe-delimited field of clave_comparacion. Filtering,
redacting, or excluding obs alone does not remove the text from the row.
Treat the two columns as one field.
valor_tierra and superficie_tierra are int64; their _edificado
counterparts are double. The pair does not have a common type. Many rows
carry 0 in both, which is a recorded absence rather than a measured zero.
The object is served as Content-Type: binary/octet-stream. The
collection declares application/vnd.apache.parquet. Dispatch on the STAC
declaration, not the header.

publishes none for this layer. The end is open because the source updates
continuously and states no cut-off.
