rust-v0.3.0

New Features 🪄

• Preliminary support for 3D (XYZ) geometries
• Support for reading and writing GeoParquet 1.1
  • Support for reading and writing GeoArrow (native) geometry encoding
  • Support for reading with spatial filtering
• Both synchronous and asynchronous readers for GeoParquet. Readers will stream a RecordBatch at a time by default.
• Accept RecordBatchReader as input to all
• New support for geoarrow.box array (equivalent to Vec<Option<geo::Rect>>). RectArray is now laid out as a StructArray internally instead of a FixedSizeListArray.
• Improved documentation

Performance Improvements 🏎️

• Remove Cow around scalar buffers by @kylebarron in #720

Bug fixes 🐛

• Don't serialize empty array metadata by @kylebarron in #678
• Fixed MixedGeometryArray handling. Exported Arrow UnionArrays always have same data layout.
• Support MapArrays when exporting to geozero by @kylebarron in #721

New Contributors

• @H-Plus-Time made their first contribution in #607
• @gadomski made their first contribution in #640

py-v0.3.0

New Features 🪄

• Remove geometry class specializations. Instead of PointArray, LineStringArray, etc, there's now just GeometryArray, ChunkedGeometryArray, and Geometry (a scalar).
• Remove GeoTable class, in favor of external, generic arrow Table implementations, such as arro3.core.Table.
• Move to slimmer, functional API. No more geometry methods on classes.
• Don't materialize input data when writing to a file.
• New GeometryType class for understanding the geometry type of an array or chunked array.
• Split Python code into three modules: geoarrow-rust-core, geoarrow-rust-compute and geoarrow-rust-io.
• Support for Pyodide Python environment
• Support Python file objects for reading and writing GeoParquet

Bug fixes 🐛

• Fix array indexing with negative integers by @kylebarron in #724

rust-v0.2.0

New! ✨

New I/O support for reading and writing to geospatial formats

• Asynchronous FlatGeobuf reader. This also supports passing a spatial filter.
• Initial support for reading from PostGIS. Note that not all Postgres data types are supported yet. Create an issue if your query fails.
• Reading and writing newline-delimited GeoJSON.
• Asynchronous GeoParquet reader for reading from remote files. By @weiji14 in #493
• Also new support for writing GeoParquet files.
• Support for reading and writing Arrow IPC files.

New algorithms!

• Explode a Table where each multi-geometry expands into multiple rows of single geometries.
• total_bounds
• frechet_distance for LineString similarity.
• line_interpolate_point and line_locate_point for linear referencing.
• polylabel for polygon labeling.

Improved usability:

• New top-level docs website.

• Initial support for reading from PostGIS. Note that not all Postgres data types are supported yet. Create an issue if your query fails.
• Reading and writing newline-delimited GeoJSON.
• Pyogrio integration for reading from OGR/GDAL.
• Asynchronous GeoParquet reader for reading from remote files. By @weiji14 in #493
• Also new support for writing GeoParquet files.
• Most I/O readers and writers support Python file-like objects (in binary mode).
• Support for reading and writing Arrow IPC files.

Better interoperability with the Python geospatial ecosystem.

• Import from and export to GeoPandas GeoDataFrames. Refer to the GeoPandas interoperability documentation.
• Import from and export to Shapely arrays. Refer to the Shapely interoperability documentation.
• Better integration with Lonboard for fast visualization in Jupyter.
• All scalars, arrays, chunked arrays, and table objects implement __geo_interface__ for interoperability with existing tools.
• Numpy interoperability for float array output from algorithms. Pass any Float64Array or BooleanArray to numpy.asarray. You can also pass a numpy array as vectorized input into a function like line_interpolate_point.

New algorithms!

• Explode a Table where each multi-geometry expands into multiple rows of single geometries.
• total_bounds
• Unified area function for planar and geodesic area.
• Unified simplify function for multiple simplification methods. Also new support for topology-preserving simplification.
• Unified length function for euclidean and geodesic length calculations.
• frechet_distance for LineString similarity.
• affine_transform, which integrates with the Python affine library.
• line_interpolate_point and line_locate_point for linear referencing.
• polylabel for polygon labeling.

Improved display of Python objects:

• Scalars now display as SVG geometries inside Jupyter environments.
• Tables, arrays, and chunked arrays implement __repr__ so that you can inspect data easily.

Improved usability:

• PointArray.from_xy to simplify creating a point array from numpy arrays of coordinates.
• Index into arrays and chunked arrays with square brackets. E.g. point_array[0] will access the first point in the array. Negative indexing is also supported, so point_array[-1] will get the last item in the array.
• New top-level docs website.
