Crate oxigdal_geoparquet 

GeoParquet Driver for OxiGDAL

This crate provides a pure Rust implementation of the GeoParquet 1.0 specification, enabling efficient reading and writing of geospatial vector data in Apache Parquet format.

Features

• Full GeoParquet 1.0 specification support
• WKB geometry encoding/decoding for all geometry types
• Spatial partitioning and indexing for efficient queries
• Zero-copy operations using Apache Arrow
• Compression support (Snappy, Gzip, Zstd, LZ4, Brotli)
• Spatial statistics and bounding box metadata
• Row group-level spatial filtering

Example

use oxigdal_geoparquet::{GeoParquetReader, GeoParquetWriter};
use oxigdal_geoparquet::metadata::{Crs, GeometryColumnMetadata};
use oxigdal_geoparquet::geometry::{Point, Geometry};

// Create a writer with WGS84 CRS
let metadata = GeometryColumnMetadata::new_wkb()
    .with_crs(Crs::wgs84());

let mut writer = GeoParquetWriter::new("output.parquet", "geometry", metadata)?;

// Add geometries
let point = Geometry::Point(Point::new_2d(-122.4, 37.8));
writer.add_geometry(&point)?;

// Finalize the file
writer.finish()?;

// Read the file
let reader = GeoParquetReader::open("output.parquet")?;
let metadata = reader.metadata();
println!("CRS: {:?}", metadata.primary_column_metadata()?.crs);
