We are pleased to announce a new release of GeoPandas!
GeoPandas 0.6.0 features a refactor of the internals based on the new
pandas ExtensionArray interface, for better integration with pandas.
Although this change should keep the user interface mostly stable, there
are a few changes summarized below. Further, this release includes a nice
set of other improvements and bug fixes. See the full list below.
Important note! This will be the last release to support Python 2.7 (#1031
<https://github.com/geopandas/geopandas/issues/1031>)
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 or are already installed (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.readthedocs.io/en/stable/
*What's new?*
API changes:
- A refactor of the internals based on the pandas ExtensionArray
interface (#1000 <https://github.com/geopandas/geopandas/issues/1000>).
The main user visible changes are:
- The .dtype of a GeoSeries is now a 'geometry' dtype (and no longer
a numpy object dtype).
- The .values of a GeoSeries now returns a custom GeometryArray, and
no longer a numpy array. To get back a numpy array of Shapely
scalars, you
can convert explicitly using np.asarray(..).
- The GeoSeries constructor now raises a warning when passed
non-geometry data. Currently the constructor falls back to return a pandas
Series, but in the future this will raise an error (#1085
<https://github.com/geopandas/geopandas/pull/1085>).
- The missing value handling has been changed to now separate the
concepts of missing geometries and empty geometries (#601
<https://github.com/geopandas/geopandas/issues/601>, 1062). In practice
this means that (see the docs
<https://geopandas.readthedocs.io/en/v0.6.0/missing_empty.html> for more
details):
- GeoSeries.isna now considers only missing values, and if you want
to check for empty geometries, you can use GeoSeries.is_empty (
GeoDataFrame.isna already only looked at missing values).
- GeoSeries.dropna now actually drops missing values (before it
didn't drop either missing or empty geometries)
- GeoSeries.fillna only fills missing values (behaviour unchanged).
- GeoSeries.align uses missing values instead of empty geometries by
default to fill non-matching index entries.
New features and improvements:
- Addition of a GeoSeries.affine_transform method, equivalent of
Shapely's function (#1008
<https://github.com/geopandas/geopandas/pull/1008>).
- Addition of a GeoDataFrame.rename_geometry method to easily rename the
active geometry column (#1053
<https://github.com/geopandas/geopandas/issues/1053>).
- Addition of geopandas.show_versions() function, which can be used to
give an overview of the installed libraries in bug reports (#899
<https://github.com/geopandas/geopandas/issues/899>).
- The legend_kwds keyword of the plot() method can now also be used to
specify keywords for the color bar (#1102
<https://github.com/geopandas/geopandas/pull/1102>).
- Performance improvement in the sjoin() operation by re-using existing
spatial index of the input dataframes, if available (#789
<https://github.com/geopandas/geopandas/pull/789>).
- Updated documentation to work with latest version of geoplot and
contextily (#1044 <https://github.com/geopandas/geopandas/pull/1044>,
#1088 <https://github.com/geopandas/geopandas/pull/1088>).
- A new geopandas.options configuration, with currently a single option
to control the display precision of the coordinates (
options.display_precision). The default is now to show less coordinates
(3 for projected and 5 for geographic coordinates), but the default can be
overridden with the option.
Bug fixes:
- Also try to use pysal instead of mapclassify if available (#1082
<https://github.com/geopandas/geopandas/pull/1082>).
- The GeoDataFrame.astype() method now correctly returns a GeoDataFrame
if the geometry column is preserved (#1009
<https://github.com/geopandas/geopandas/pull/1009>).
- The to_crs method now uses always_xy=True to ensure correct lon/lat
order handling for pyproj>=2.2.0 (#1122
<https://github.com/geopandas/geopandas/pull/1122>).
- Fixed passing list-like colors in the plot() method in case of "multi"
geometries (#1119 <https://github.com/geopandas/geopandas/pull/1119>).
- Fixed the coloring of shapes and colorbar when passing a custom norm
in the plot() method (#1091
<https://github.com/geopandas/geopandas/pull/1091>, #1089
<https://github.com/geopandas/geopandas/pull/1089>).
- Fixed GeoDataFrame.to_file to preserve VFS file paths (e.g. when a
"s3://" path is specified) (#1124
<https://github.com/geopandas/geopandas/pull/1124>).
- Fixed failing case in geopandas.sjoin with empty geometries (#1138
<https://github.com/geopandas/geopandas/pull/1138>).
In addition, the minimum required versions of some dependencies have been
increased: GeoPandas now requires pandas >=0.23.4 and matplotlib >=2.0.1 (
#1002 <https://github.com/geopandas/geopandas/pull/1002>).

*What's new?*
Improvements:
- Significant performance improvement (around 10x) for
GeoDataFrame.iterfeatures, which also improves GeoDataFrame.to_file (#864
<https://github.com/geopandas/geopandas/pull/864>).
- File IO enhancements based on Fiona 1.8:
- Support for writing bool dtype (#855
<https://github.com/geopandas/geopandas/pull/855>) and datetime
dtype, if the file format supports it (#728
<https://github.com/geopandas/geopandas/pull/728>).
- Support for writing dataframes with multiple geometry types, if the
file format allows it (e.g. GeoJSON for all types, or ESRI Shapefile for
Polygon+MultiPolygon) (#827
<https://github.com/geopandas/geopandas/pull/827>, #867
<https://github.com/geopandas/geopandas/issues/867>, #870
<https://github.com/geopandas/geopandas/pull/870>).
- Compatibility with pyproj >= 2 (#962
<https://github.com/geopandas/geopandas/pull/962>).
- A new geopandas.points_from_xy() helper function to convert x and y
coordinates to Point objects (#896
<https://github.com/geopandas/geopandas/pull/896>).
- The buffer and interpolate methods now accept an array-like to specify
a variable distance for each geometry (#781
<https://github.com/geopandas/geopandas/pull/781>).
- Addition of a relate method, corresponding to the shapely method that
returns the DE-9IM matrix (#853
<https://github.com/geopandas/geopandas/pull/853>).
- Plotting improvements:
- Performance improvement in plotting by only flattening the
geometries if there are actually 'Multi' geometries (#785
<https://github.com/geopandas/geopandas/pull/785>).
- Choropleths: access to all mapclassify classification schemes and
addition of the classification_kwds keyword in the plot method to
specify options for the scheme (#876
<https://github.com/geopandas/geopandas/pull/876>).
- Ability to specify a matplotlib axes object on which to plot the
color bar with the cax keyword, in order to have more control over
the color bar placement (#894
<https://github.com/geopandas/geopandas/pull/894>).
- Changed the default provider in geopandas.tools.geocode from Google
(now requires an API key) to Geocode.Farm (#907
<https://github.com/geopandas/geopandas/pull/907>, #975
<https://github.com/geopandas/geopandas/pull/975>).
Bug fixes:
- Remove the edge in the legend marker (#807
<https://github.com/geopandas/geopandas/pull/807>).
- Fix the align method to preserve the CRS (#829
<https://github.com/geopandas/geopandas/pull/829>).
- Fix geopandas.testing.assert_geodataframe_equal to correctly compare
left and right dataframes (#810
<https://github.com/geopandas/geopandas/pull/810>).
- Fix in choropleth mapping when the values contain missing values (#877
<https://github.com/geopandas/geopandas/issues/877>).
- Better error message in sjoin if the input is not a GeoDataFrame (#842
<https://github.com/geopandas/geopandas/pull/842>).
- Fix in read_postgis to handle nullable (missing) geometries (#856
<https://github.com/geopandas/geopandas/pull/856>).
- Correctly passing through the parse_dates keyword in read_postgis to
the underlying pandas method (#860
<https://github.com/geopandas/geopandas/pull/860>).
- Fixed the shape of Antarctica in the included demo dataset
'naturalearth_lowres'
(by updating to the latest version) (#804
<https://github.com/geopandas/geopandas/issues/804>).
