GeoJSON to Parquet Online — Convert Geospatial Features for Analytics
By ParquetReader Team
Why convert GeoJSON to Parquet
GeoJSON is flexible and great for interchange, but large feature collections become expensive to scan repeatedly.
Parquet gives better compression and faster analytical queries on attribute columns.
Preserve geometry and attributes
Before export, verify key geometry and property fields so the dataset remains useful downstream.
Use SQL to inspect coverage by type or region before writing the Parquet output.
Quality checks with SQL
Example checks: SELECT COUNT(*) FROM dataset WHERE geometry IS NULL; and SELECT feature_type, COUNT(*) FROM dataset GROUP BY feature_type;.
Run bounding or category checks to detect malformed records early.
Export strategy for large spatial datasets
Keep the canonical dataset in Parquet for processing and query speed.
Generate JSON or CSV exports only when needed for sharing or external tools.
