pyogrio

Pyogrio provides fast, bulk-oriented read and write access to
GDAL/OGR vector data
sources, such as ESRI Shapefile, GeoPackage, GeoJSON, and several others.
Vector data sources typically have geometries, such as points, lines, or
polygons, and associated records with potentially many columns worth of data.

The typical use is to read or write these data sources to/from
GeoPandas GeoDataFrames. Because
the geometry column is optional, reading or writing only non-spatial data is
also possible. Hence, GeoPackage attribute tables, DBF files, or CSV files are
also supported.

Pyogrio is fast because it uses pre-compiled bindings for GDAL/OGR to read and
write the data records in bulk. This approach avoids multiple steps of
converting to and from Python data types within Python, so performance becomes
primarily limited by the underlying I/O speed of data source drivers in
GDAL/OGR.

We have seen >5-10x speedups reading files and >5-20x speedups writing files
compared to using row-per-row approaches (e.g. Fiona).

Requirements

Supports Python 3.9 - 3.13 and GDAL 3.4.x - 3.9.x.

Reading to GeoDataFrames requires geopandas>=0.12 with shapely>=2.

Additionally, installing pyarrow in combination with GDAL 3.6+ enables
a further speed-up when specifying use_arrow=True.

Installation

Pyogrio is currently available on
conda-forge
and PyPI
for Linux, MacOS, and Windows.

Please read the
installation documentation
for more information.

Supported vector formats

Pyogrio supports most common vector data source formats (provided they are also
supported by GDAL/OGR), including ESRI Shapefile, GeoPackage, GeoJSON, and
FlatGeobuf.

Please see the list of supported formats
for more information.

Getting started

Please read the introduction
for more information and examples to get started using Pyogrio.

You can also check out the API documentation
for full details on using the API.
