What Is GeoParquet? Columnar Geospatial Data for Analytics

Learn what GeoParquet is, why it’s popular for large geospatial datasets, and how to open GeoParquet online for quick inspection.

GeoParquet is a Parquet-based format for storing geospatial data in a columnar, analytics-friendly way. It’s often used in data engineering and cloud analytics workflows where performance and interoperability matter for large datasets.

To preview a GeoParquet file quickly, use the GeoParquet viewer: /open-geoparquet-online/.

Why GeoParquet is different

Compared to text-based formats, Parquet is designed for analytics:

  • Columnar storage (faster scans for selected fields)
  • Compression and efficient encoding
  • Friendly for large-scale processing tools

GeoParquet adds conventions to represent geometry and geospatial metadata.

Common use cases

  • Large-scale spatial analytics and ETL pipelines
  • Sharing datasets for modern data platforms
  • Efficient storage for repeated querying and filtering

Limitations to know

  • It’s not as universally supported by classic desktop GIS tools as Shapefile.
  • It’s often better as a “data lake” format than a hand-edited format.

How to open GeoParquet online

  1. Go to /open-geoparquet-online/.
  2. Upload your .parquet file.
  3. Inspect geometry and attributes to validate the dataset.
