Geoparquet is a set of conventions for storing geospatial data in Parquet files.

Standardization is happening at geoparquet.org.

GeoParquet file is a Parquet file that additionally follows these conventions:

  • Geospatial metadata describing any geospatial columns is stored in the Parquet file's schema metadata (as stringified JSON).
  • Geometry columns are WKB encoded (additional encodings will likely be added)/

Alternatives​

GeoParquet can be compared to GeoArrow, as both are binary columnar formats with a high degree of similarity.
