This resource introduces GeoArrow, a new specification designed to enable seamless and performant handling of geospatial data within Apache Arrow-compatible systems. It highlights how GeoArrow overcomes challenges in representing and transporting complex geospatial information, allowing for efficient data transfer and integration within composable data pipelines without requiring modifications to intermediary components. The document also demonstrates significant improvements in speed and file size when using GeoArrow with formats like Parquet for geospatial data analysis.
