ANN: GeoPandas 0.4.0 released

by Joris Van den Bossche

We are pleased to announce a new release of GeoPandas! Most notably, GeoPandas 0.4.0 improves the overlay functionality (much better performance, and fixed behaviour for certain cases). This can possibly change results you obtained before, but likely more correct now. But given this change, please test and feedback welcome! Further, there is a long list of other new features and bug fixes, see below. GeoPandas can be installed with conda from the conda-forge channel (conda install -c conda-forge geopandas) or with pip assuming the dependencies are available for your platform (pip install geopandas). Please report any issues, or request new features via our GitHub repository: https://github.com/geopandas/geopandas/issues *What is it?* GeoPandas is an open source project to make working with geospatial data in python easier. GeoPandas combines the capabilities of pandas and shapely, providing geospatial operations in pandas and a high-level interface to multiple shapely geometries. GeoPandas enables you to easily do operations in python that would otherwise require a spatial database such as PostGIS. Documentation can be found here: http://geopandas.org/ <http://geopandas.readthedocs.io/en/stable/> *What's new?* Improvements: - Improved overlay function (better performance, several incorrect behaviours fixed) (#429 <https://github.com/geopandas/geopandas/pull/429> ) - Pass keywords to control legend behavior (legend_kwds) to plot (#434 <https://github.com/geopandas/geopandas/pull/434>) - Add basic support for reading remote datasets in read_file (#531 <https://github.com/geopandas/geopandas/pull/531>) - Pass kwargs for buffer operation on GeoSeries (#535 <https://github.com/geopandas/geopandas/pull/535>) - Expose all geopy services as options in geocoding (#550 <https://github.com/geopandas/geopandas/pull/550>) - Faster write speeds to GeoPackage (#605 <https://github.com/geopandas/geopandas/pull/605>) - Permit read_file filtering with a bounding box from a GeoDataFrame ( #613 <https://github.com/geopandas/geopandas/pull/613>) - Set CRS on GeoDataFrame returned by read_postgis (#627 <https://github.com/geopandas/geopandas/pull/627>) - Permit setting markersize for Point GeoSeries plots with column values (#633 <https://github.com/geopandas/geopandas/pull/633>) - Started an example gallery (#463 <https://github.com/geopandas/geopandas/pull/463>, #690 <https://github.com/geopandas/geopandas/pull/690>, #717 <https://github.com/geopandas/geopandas/pull/717>) - Support for plotting MultiPoints (#683 <https://github.com/geopandas/geopandas/pull/683>) - Testing functionalty (e.g. assert_geodataframe_equal) is now publicly exposed (#707 <https://github.com/geopandas/geopandas/pull/707>) - Add explode method to GeoDataFrame (similar to the GeoSeries method) ( #671 <https://github.com/geopandas/geopandas/pull/671>) - Set equal aspect on active axis on multi-axis figures (#718 <https://github.com/geopandas/geopandas/pull/718>) - Pass array of values to column argument in plot (#770 <https://github.com/geopandas/geopandas/pull/770>) Bug fixes : - Ensure that colorbars are plotted on the correct axis (#523 <https://github.com/geopandas/geopandas/pull/523>) - Handle plotting empty GeoDataFrame (#571 <https://github.com/geopandas/geopandas/pull/571>) - Save z-dimension when writing files (#652 <https://github.com/geopandas/geopandas/pull/652>) - Handle reading empty shapefiles (#653 <https://github.com/geopandas/geopandas/pull/653>) - Correct dtype for empty result of spatial operations (#685 <https://github.com/geopandas/geopandas/issues/685>) - Fix empty sjoin handling for pandas>=0.23 (#762 <https://github.com/geopandas/geopandas/pull/762>) *Acknowledgments* Thanks to everyone who contributed to this release!
