Version 0.12 (2021-12-03)

Distribution

  • Distribute binary wheels for Apple Silicon architecture (arm64 and universal2) (#427).

  • Removed 32-bit architecture wheels for Python 3.10 (#427).

  • All binary wheels now have GEOS 3.10.1. See https://github.com/libgeos/geos/blob/main/NEWS for the changes (#422).

  • Linux x86_64 and i686 wheels are now built using the manylinux2014 image instead of manylinux2010 (#445).

Major enhancements

  • Added pygeos.dwithin for GEOS >= 3.10 (#417).

  • Added dwithin predicate to STRtree query and query_bulk methods to find geometries within a search distance for GEOS >= 3.10 (#425).

  • Added GeoJSON input/output capabilities (pygeos.from_geojson, pygeos.to_geojson) for GEOS >= 3.10 (#413).

  • Performance improvement in constructing LineStrings or LinearRings from numpy arrays for GEOS >= 3.10 (#436)

API Changes

  • When constructing a linearring through pygeos.linearrings or a polygon through pygeos.polygons the ring is automatically closed when supplied with 3 coordinates also when the first and last are already equal (#431).

Bug fixes

  • Raise GEOSException in the rare case when predicate evalution in STRtree.query errors. Previously, the exceptions were ignored silently and the geometry was added to the result (as if the predicate returned True) (#432).

  • Hide RuntimeWarning when using total_bounds on empty geometries, empty arrays, or geometries with NaN coordinates (#441).

Version 0.11.1 (2021-10-30)

Distribution

Major enhancements

  • Optionally output to a user-specified array (out keyword argument) when constructing geometries from indices (#380).

  • Added pygeos.empty to create a geometry array pre-filled with None or with empty geometries (#381).

  • Added pygeos.force_2d and pygeos.force_3d to change the dimensionality of the coordinates in a geometry (#396).

  • Added pygeos.testing.assert_geometries_equal (#401).

API Changes

  • The default behaviour of pygeos.set_precision is now to always return valid geometries. Before, the default was preserve_topology=False which caused confusion because it mapped to GEOS_PREC_NO_TOPO (the new ‘pointwise’). At the same time, GEOS < 3.10 implementation was not entirely correct so that some geometries did and some did not preserve topology with this mode. Now, the new mode argument controls the behaviour and the preserve_topology argument is deprecated (#410).

  • When constructing a linearring through pygeos.linearrings or a polygon through pygeos.polygons now a ValueError is raised (instead of a GEOSException) if the ring contains less than 4 coordinates including ring closure (#378).

  • Removed deprecated normalize keyword argument in pygeos.line_locate_point and pygeos.line_interpolate_point (#410).

Bug fixes

  • Return True instead of False for LINEARRING geometries in is_closed (#379).

  • Fixed the WKB serialization of 3D empty points for GEOS >= 3.9.0 (#392).

  • Fixed the WKT serialization of single part 3D empty geometries for GEOS >= 3.9.0 (#402).

  • Fixed the WKT serialization of multipoints with empty points for GEOS >= 3.9.0 (#392).

  • Fixed a segfault when getting coordinates from empty points in GEOS 3.8.0 (#415).

Version 0.10.2 (2021-08-23)

Distribution

Unittests are now included in the pygeos distribution. Run them by 1) installing pytest (or pygeos[test]) and 2) invoking pytest --pyargs pygeos.tests.

We started using a new tool for building binary wheels: cibuildwheel. This resulted into the following improvements in the distributed binary wheels:

  • Windows binary wheels now contain mangled DLLs, which avoids conflicts with other GEOS versions present on the system (a.k.a. ‘DLL hell’) (#365).

  • Windows binary wheels now contain the Microsoft Visual C++ Runtime Files (msvcp140.dll) for usage on systems without the C++ redistributable (#365).

  • Linux x86_64 and i686 wheels are now built using the manylinux2010 image instead of manylinux1 (#365).

  • Linux aarch64 wheels are now available for Python 3.9 (manylinux2014, #365).

Bug fixes

  • Fixed operations on geometry arrays containing NULL instead of None. These occur for instance by using numpy.empty_like (#371)

  • Released the GIL in all geometry creation functions (#310, #326).

  • Added the option to return the geometry index in get_coordinates (#318).

  • Added the get_rings function, similar as get_parts but specifically to extract the rings of Polygon geometries (#342).

API Changes

  • STRtree default leaf size is now 10 instead of 5, for somewhat better performance under normal conditions (#286)

  • Addition of on_invalid parameter to from_wkb and from_wkt to optionally return invalid WKB geometries as None.

Version 0.9 (2021-01-23)

  • intersection_all and symmetric_difference_all now ignore None values instead of returning None if any value is None (#249)

  • union_all now returns None (instead of GEOMETRYCOLLECTION EMPTY) if all input values are None (#249)

  • The default axis of union_all, intersection_all, symmetric_difference_all, and coverage_union_all can now reduce over multiple axes. The default changed from the first axis (0) to all axes (None) (#266)

  • Argument in line_interpolate_point and line_locate_point was renamed from normalize to normalized (#209)

  • Addition of grid_size parameter to specify fixed-precision grid for difference, intersection, symmetric_difference, union, and union_all operations for GEOS >= 3.9 (#276)

Version 0.5 (2019-10-25)

Highlights of this release:

  • Moved to the pygeos GitHub organization.

  • Addition of functionality to get and transform all coordinates (eg for reprojections or affine transformations) [#44]

  • Ufuncs for converting to and from the WKT and WKB formats [#45]

  • equals_exact has been added [PR #57]

Version 0.4 (2019-09-16)

This is a major release of PyGEOS and the first one with actual release notes. Most important features of this release are:

  • buffer and haussdorff_distance were completed [#15]

  • voronoi_polygons and delaunay_triangles have been added [#17]

  • The PyGEOS documentation is now mostly complete and available on http://pygeos.readthedocs.io .

  • The concepts of “empty” and “missing” geometries have been separated. The pygeos.Empty and pygeos.NaG objects has been removed. Empty geometries are handled the same as normal geometries. Missing geometries are denoted by None and are handled by every pygeos function. NaN values cannot be used anymore to denote missing geometries. [PR #36]

  • Added pygeos.__version__ and pygeos.geos_version. [PR #43]
