O formacie GeoParquet

Parquet is a columnar storage format from Apache: data lies by column, each one compressed separately, and block headers carry statistics, so the engine reads only the columns it needs and skips the rest of the rows. GeoParquet (the OGC standard, version 1.0) adds to that an agreement on how to store geometry and the coordinate system.

It is a format for analytics and long-term storage: a data lake in object storage, a data mart in BigQuery or Snowflake, heavy computation in DuckDB and GeoPandas. On large selections it is both smaller on disk and faster in queries than row-based formats.

The output is a single .parquet: all the layers merged into one table with a _layer column you can split them by. Geometry is stored in binary WKB form, and the WGS84 (EPSG:4326) coordinate system is described in the file metadata per the GeoParquet specification. The default compression is snappy.

You cannot look at such a file with your own eyes, it is binary. But it is read by DuckDB, GeoPandas, Spark, BigQuery, QGIS and ogr2ogr, usually without loading it into a database at all.

Kto korzysta z map GeoParquet

🏗

Analityka Big Data

Millions of features are processed in DuckDB or Spark without loading them into a database.

💻

Jezioro danych

The file goes into the data lake next to the other tables and is read by the same tools.

📊

Uczenie maszynowe

Spatial features for models in a format GeoPandas reads in one line.

🎨

Pamięć masowa w chmurze

The data sits in object storage and is read directly, with no server.

🗺

Zapytania kolumnowe

Only the columns you need are read — a query on one field does not pull up the whole file.

Jak otworzyć po eksporcie

DuckDB — INSTALL spatial; LOAD spatial; SELECT * FROM 'map.parquet' WHERE _layer='buildings'; the query runs straight against the file, no import needed.
Python — geopandas.read_parquet("map.parquet"), then the usual GeoDataFrame work, spatial joins included.
QGIS 3.28 and newer — opens GeoParquet if the GDAL build has Parquet support; if the format is not visible, convert it: ogr2ogr -f GPKG out.gpkg map.parquet.
Cloud storage — the file goes into S3 or GCS and is read from there directly by the DuckDB, Spark and BigQuery engines, with no database to stand up.
Splitting by layer — save separate files from GeoPandas with a filter on _layer if the consumer only needs one layer.
