Version 0.12.1 (October 29, 2022)#

Small bug-fix release removing the shapely<2 pin in the installation requirements.

Version 0.12 (October 24, 2022)#

The highlight of this release is the support for Shapely 2.0. This makes it possible to test Shapely 2.0 (currently 2.0b1) alongside GeoPandas.

Note that if you also have PyGEOS installed, you need to set an environment variable (USE_PYGEOS=0) before importing geopandas to actually test Shapely 2.0 features instead of PyGEOS. See https://geopandas.org/en/latest/getting_started/install.html#using-the-optional-pygeos-dependency for more details.

New features and improvements:

  • Added normalize() method from shapely to GeoSeries/GeoDataframe (#2537).

  • Added make_valid() method from shapely to GeoSeries/GeoDataframe (#2539).

  • Added where filter to read_file (#2552).

  • Updated the distributed natural earth datasets (naturalearth_lowres and naturalearth_cities) to version 5.1 (#2555).

Deprecations and compatibility notes:

  • Accessing the crs of a GeoDataFrame without active geometry column was deprecated and this now raises an AttributeError (#2578).

  • Resolved colormap-related warning in .explore() for recent Matplotlib versions (#2596).

Bug fixes:

  • Fix cryptic error message in geopandas.clip() when clipping with an empty geometry (#2589).

  • Accessing gdf.geometry where the active geometry column is missing, and a column named "geometry" is present will now raise an AttributeError, rather than returning gdf["geometry"] (#2575).

  • Combining GeoSeries/GeoDataFrames with pandas.concat will no longer silently override CRS information if not all inputs have the same CRS (#2056).

Version 0.11.1 (July 24, 2022)#

Small bug-fix release:

  • Fix regression (RecursionError) in reshape methods such as unstack() and pivot() involving MultiIndex, or GeoDataFrame construction with MultiIndex (#2486).

  • Fix regression in GeoDataFrame.explode() with non-default geometry column name.

  • Fix regression in apply() causing row-wise all nan float columns to be casted to GeometryDtype (#2482).

  • Fix a crash in datetime column reading where the file contains mixed timezone offsets (#2479). These will be read as UTC localized values.

  • Fix a crash in datetime column reading where the file contains datetimes outside the range supported by [ns] precision (#2505).

  • Fix regression in passing the Parquet or Feather format version in to_parquet and to_feather. As a result, the version parameter for the to_parquet and to_feather methods has been replaced with schema_version. version will be passed directly to underlying feather or parquet writer. version will only be used to set schema_version if version is one of 0.1.0 or 0.4.0 (#2496).

Version 0.11 (June 20, 2022)#

Highlights of this release:

  • The geopandas.read_file() and GeoDataFrame.to_file() methods to read and write GIS file formats can now optionally use the pyogrio package under the hood through the engine="pyogrio" keyword. The pyogrio package implements vectorized IO for GDAL/OGR vector data sources, and is faster compared to the fiona-based engine (#2225).

  • GeoParquet support updated to implement v0.4.0 of the OpenGeospatial/GeoParquet specification (#2441). Backwards compatibility with v0.1.0 of the metadata spec (implemented in the previous releases of GeoPandas) is guaranteed, and reading and writing Parquet and Feather files will no longer produce a UserWarning (#2327).

New features and improvements:

  • Improved handling of GeoDataFrame when the active geometry column is lost from the GeoDataFrame. Previously, square bracket indexing gdf[[...]] returned a GeoDataFrame when the active geometry column was retained and a DataFrame was returned otherwise. Other pandas indexing methods (loc, iloc, etc) did not follow the same rules. The new behaviour for all indexing/reshaping operations is now as follows (#2329, #2060):

    • If operations produce a DataFrame containing the active geometry column, a GeoDataFrame is returned

    • If operations produce a DataFrame containing GeometryDtype columns, but not the active geometry column, a GeoDataFrame is returned, where the active geometry column is set to None (set the new geometry column with set_geometry())

    • If operations produce a DataFrame containing no GeometryDtype columns, a DataFrame is returned (this can be upcast again by calling set_geometry() or the GeoDataFrame constructor)

    • If operations produce a Series of GeometryDtype, a GeoSeries is returned, otherwise Series is returned.

    • Error messages for having an invalid geometry column have been improved, indicating the name of the last valid active geometry column set and whether other geometry columns can be promoted to the active geometry column (#2329).

  • Datetime fields are now read and written correctly for GIS formats which support them (e.g. GPKG, GeoJSON) with fiona 1.8.14 or higher. Previously, datetimes were read as strings (#2202).

  • folium.Map keyword arguments can now be specified as the map_kwds argument to GeoDataFrame.explore() method (#2315).

  • Add a new parameter style_function to GeoDataFrame.explore() to enable plot styling based on GeoJSON properties (#2377).

  • It is now possible to write an empty GeoDataFrame to a file for supported formats (#2240). Attempting to do so will now emit a UserWarning instead of a ValueError.

  • Fast rectangle clipping has been exposed as GeoSeries/GeoDataFrame.clip_by_rect() (#1928).

  • The mask parameter of GeoSeries/GeoDataFrame.clip() now accepts a rectangular mask as a list-like to perform fast rectangle clipping using the new GeoSeries/GeoDataFrame.clip_by_rect() (#2414).

  • Bundled demo dataset naturalearth_lowres has been updated to version 5.0.1 of the source, with field ISO_A3 manually corrected for some cases (#2418).

Deprecations and compatibility notes:

  • The active development branch of geopandas on GitHub has been renamed from master to main (#2277).

  • Deprecated methods GeometryArray.equals_exact() and GeometryArray.almost_equals() have been removed. They should be replaced with GeometryArray.geom_equals_exact() and GeometryArray.geom_almost_equals() respectively (#2267).

  • Deprecated CRS functions explicit_crs_from_epsg(), epsg_from_crs() and get_epsg_file_contents() were removed (#2340).

  • Warning about the behaviour change to GeoSeries.isna() with empty geometries present has been removed (#2349).

  • Specifying a CRS in the GeoDataFrame/GeoSeries constructor which contradicted the underlying GeometryArray now raises a ValueError (#2100).

  • Specifying a CRS in the GeoDataFrame constructor when no geometry column is provided and calling GeoDataFrame. set_crs on a GeoDataFrame without an active geometry column now raise a ValueError (#2100)

  • Passing non-geometry data to theGeoSeries constructor is now fully deprecated and will raise a TypeError (#2314). Previously, a pandas.Series was returned for non-geometry data.

  • Deprecated GeoSeries/GeoDataFrame set operations __xor__(), __or__(), __and__() and __sub__(), geopandas.io.file.read_file/to_file and geopandas.io.sql.read_postgis now emit FutureWarning instead of DeprecationWarning and will be completely removed in a future release.

  • Accessing the crs of a GeoDataFrame without active geometry column is deprecated and will be removed in GeoPandas 0.12 (#2373).

Bug fixes:

  • GeoSeries.to_frame now creates a GeoDataFrame with the geometry column name set correctly (#2296)

  • Fix pickle files created with pygeos installed can not being readable when pygeos is not installed (#2237).

  • Fixed UnboundLocalError in GeoDataFrame.plot() using legend=True and missing_kwds (#2281).

  • Fix explode() incorrectly relating index to columns, including where the input index is not unique (#2292)

  • Fix GeoSeries.[xyz] raising an IndexError when the underlying GeoSeries contains empty points (#2335). Rows corresponding to empty points now contain np.nan.

  • Fix GeoDataFrame.iloc raising a TypeError when indexing a GeoDataFrame with only a single column of GeometryDtype (#1970).

  • Fix GeoDataFrame.iterfeatures() not returning features with the same field order as GeoDataFrame.columns (#2396).

  • Fix GeoDataFrame.from_features() to support reading GeoJSON with null properties (#2243).

  • Fix GeoDataFrame.to_parquet() not intercepting engine keyword argument, breaking consistency with pandas (#2227)

  • Fix GeoDataFrame.explore() producing an error when column is of boolean dtype (#2403).

  • Fix an issue where GeoDataFrame.to_postgis() output the wrong SRID for ESRI authority CRS (#2414).

  • Fix GeoDataFrame.from_dict/from_features classmethods using GeoDataFrame rather than cls as the constructor.

  • Fix GeoDataFrame.plot() producing incorrect colors with mixed geometry types when colors keyword is provided. (#2420)

Notes on (optional) dependencies:

  • GeoPandas 0.11 drops support for Python 3.7 and pandas 0.25 (the minimum supported pandas version is now 1.0.5). Further, the minimum required versions for the listed dependencies have now changed to shapely 1.7, fiona 1.8.13.post1, pyproj 2.6.1.post1, matplotlib 3.2, mapclassify 2.4.0 (#2358, #2391)

Version 0.10.2 (October 16, 2021)#

Small bug-fix release:

  • Fix regression in overlay() in case no geometries are intersecting (but have overlapping total bounds) (#2172).

  • Fix regression in overlay() with keep_geom_type=True in case the overlay of two geometries in a GeometryCollection with other geometry types (#2177).

  • Fix overlay() to honor the keep_geom_type keyword for the op="differnce" case (#2164).

  • Fix regression in plot() with a mapclassify scheme in case the formatted legend labels have duplicates (#2166).

  • Fix a bug in the explore() method ignoring the vmin and vmax keywords in case they are set to 0 (#2175).

  • Fix unary_union to correctly handle a GeoSeries with missing values (#2181).

  • Avoid internal deprecation warning in clip() (#2179).

Version 0.10.1 (October 8, 2021)#

Small bug-fix release:

  • Fix regression in overlay() with non-overlapping geometries and a non-default how (i.e. not “intersection”) (#2157).

Version 0.10.0 (October 3, 2021)#

Highlights of this release:

  • A new sjoin_nearest() method to join based on proximity, with the ability to set a maximum search radius (#1865). In addition, the sindex attribute gained a new method for a “nearest” spatial index query (#1865, #2053).

  • A new explore() method on GeoDataFrame and GeoSeries with native support for interactive visualization based on folium / leaflet.js (#1953)

  • The geopandas.sjoin()/overlay()/clip() functions are now also available as methods on the GeoDataFrame (#2141, #1984, #2150).

New features and improvements:

  • Add support for pandas’ value_counts() method for geometry dtype (#2047).

  • The explode() method has a new ignore_index keyword (consistent with pandas’ explode method) to reset the index in the result, and a new index_parts keywords to control whether a cumulative count indexing the parts of the exploded multi-geometries should be added (#1871).

  • points_from_xy() is now available as a GeoSeries method from_xy (#1936).

  • The to_file() method will now attempt to detect the driver (if not specified) based on the extension of the provided filename, instead of defaulting to ESRI Shapefile (#1609).

  • Support for the storage_options keyword in read_parquet() for specifying filesystem-specific options (e.g. for S3) based on fsspec (#2107).

  • The read/write functions now support ~ (user home directory) expansion (#1876).

  • Support the convert_dtypes() method from pandas to preserve the GeoDataFrame class (#2115).

  • Support WKB values in the hex format in GeoSeries.from_wkb() (#2106).

  • Update the estimate_utm_crs() method to handle crossing the antimeridian with pyproj 3.1+ (#2049).

  • Improved heuristic to decide how many decimals to show in the repr based on whether the CRS is projected or geographic (#1895).

  • Switched the default for geocode() from GeoCode.Farm to the Photon geocoding API (https://photon.komoot.io) (#2007).

Deprecations and compatibility notes:

  • The op= keyword of sjoin() to indicate which spatial predicate to use for joining is being deprecated and renamed in favor of a new predicate= keyword (#1626).

  • The cascaded_union attribute is deprecated, use unary_union instead (#2074).

  • Constructing a GeoDataFrame with a duplicated “geometry” column is now disallowed. This can also raise an error in the pd.concat(.., axis=1) function if this results in duplicated active geometry columns (#2046).

  • The explode() method currently returns a GeoSeries/GeoDataFrame with a MultiIndex, with an additional level with indices of the parts of the exploded multi-geometries. For consistency with pandas, this will change in the future and the new index_parts keyword is added to control this.

Bug fixes:

  • Fix in the clip() function to correctly clip MultiPoints instead of leaving them intact when partly outside of the clip bounds (#2148).

  • Fix GeoSeries.isna() to correctly return a boolean Series in case of an empty GeoSeries (#2073).

  • Fix the GeoDataFrame constructor to preserve the geometry name when the argument is already a GeoDataFrame object (i.e. GeoDataFrame(gdf)) (#2138).

  • Fix the handling of missing values in to/from_wkb and to_from_wkt (#1891).

  • Fix to_file() and to_json() when DataFrame has duplicate columns to raise an error (#1900).

  • Fix bug in the colors shown with user-defined classification scheme (#2019).

  • Fix handling of the path_effects keyword in plot() (#2127).

  • Fix GeoDataFrame.explode() to preserve attrs (#1935)

Notes on (optional) dependencies:

  • GeoPandas 0.10.0 dropped support for Python 3.6 and pandas 0.24. Further, the minimum required versions are numpy 1.18, shapely 1.6, fiona 1.8, matplotlib 3.1 and pyproj 2.2.

  • Plotting with a classification schema now requires mapclassify version >= 2.4 (#1737).

Many documentation improvements and a restyled and restructured website with a new logo (#1564, #1579, #1617, #1668, #1731, #1750, #1757, #1759).

New features and improvements:

  • The geopandas.read_file function now accepts more general file-like objects (e.g. fsspec open file objects). It will now also automatically recognize zipped files (#1535).

  • The GeoDataFrame.plot() method now provides access to the pandas plotting functionality for the non-geometry columns, either using the kind keyword or the accessor method (e.g. gdf.plot(kind="bar") or gdf.plot.bar()) (#1465).

  • New from_wkt(), from_wkb(), to_wkt(), to_wkb() methods for GeoSeries to construct a GeoSeries from geometries in WKT or WKB representation, or to convert a GeoSeries to a pandas Seriew with WKT or WKB values (#1710).

  • New GeoSeries.z attribute to access the z-coordinates of Point geometries (similar to the existing .x and .y attributes) (#1773).

  • The to_crs() method now handles missing values (#1618).

  • Support for pandas’ new .attrs functionality (#1658).

  • The dissolve() method now allows dissolving by no column (by=None) to create a union of all geometries (single-row GeoDataFrame) (#1568).

  • New estimate_utm_crs() method on GeoSeries/GeoDataFrame to determine the UTM CRS based on the bounds (#1646).

  • GeoDataFrame.from_dict() now accepts geometry and crs keywords (#1619).

  • GeoDataFrame.to_postgis() and geopandas.read_postgis() now supports both sqlalchemy engine and connection objects (#1638).

  • The GeoDataFrame.explode() method now allows exploding based on a non-geometry column, using the pandas implementation (#1720).

  • Performance improvement in GeoDataFrame/GeoSeries.explode() when using the PyGEOS backend (#1693).

  • The binary operation and predicate methods (eg intersection(), intersects()) have a new align keyword which allows optionally not aligning on the index before performing the operation with align=False (#1668).

  • The GeoDataFrame.dissolve() method now supports all relevant keywords of groupby(), i.e. the level, sort, observed and dropna keywords (#1845).

  • The geopandas.overlay() function now accepts make_valid=False to skip the step to ensure the input geometries are valid using buffer(0) (#1802).

  • The GeoDataFrame.to_json() method gained a drop_id keyword to optionally not write the GeoDataFrame’s index as the “id” field in the resulting JSON (#1637).

  • A new aspect keyword in the plotting methods to optionally allow retaining the original aspect (#1512)

  • A new interval keyword in the legend_kwds group of the plot() method to control the appearance of the legend labels when using a classification scheme (#1605).

  • The spatial index of a GeoSeries (accessed with the sindex attribute) is now stored on the underlying array. This ensures that the spatial index is preserved in more operations where possible, and that multiple geometry columns of a GeoDataFrame can each have a spatial index (#1444).

  • Addition of a has_sindex attribute on the GeoSeries/GeoDataFrame to check if a spatial index has already been initialized (#1627).

  • The geopandas.testing.assert_geoseries_equal() and assert_geodataframe_equal() testing utilities now have a normalize keyword (False by default) to normalize geometries before comparing for equality (#1826). Those functions now also give a more informative error message when failing (#1808).

Deprecations and compatibility notes:

  • The is_ring attribute currently returns True for Polygons. In the future, this will be False (#1631). In addition, start to check it for LineStrings and LinearRings (instead of always returning False).

  • The deprecated objects keyword in the intersection() method of the GeoDataFrame/GeoSeries.sindex spatial index object has been removed (#1444).

Bug fixes:

  • Fix regression in the plot() method raising an error with empty geometries (#1702, #1828).

  • Fix geopandas.overlay() to preserve geometries of the correct type which are nested within a GeometryCollection as a result of the overlay operation (#1582). In addition, a warning will now be raised if geometries of different type are dropped from the result (#1554).

  • Fix the repr of an empty GeoSeries to not show spurious warnings (#1673).

  • Fix the .crs for empty GeoDataFrames (#1560).

  • Fix geopandas.clip to preserve the correct geometry column name (#1566).

  • Fix the plot() method to correctly align values passed to the column keyword as a pandas Series (#1670).

  • Fix bug in plotting MultiPoints when passing values to determine the color (#1694)

  • The rename_geometry() method now raises a more informative error message when a duplicate column name is used (#1602).

  • Fix explode() method to preserve the CRS (#1655)

  • Fix the GeoSeries.apply() method to again accept the convert_dtype keyword to be consistent with pandas (#1636).

  • Fix GeoDataFrame.apply() to preserve the CRS when possible (#1848).

  • Fix bug in containment test as geom in geoseries (#1753).

  • The shift() method of a GeoSeries/GeoDataFrame now preserves the CRS (#1744).

  • The PostGIS IO functionality now quotes table names to ensure it works with case-sensitive names (#1825).

  • Fix the GeoSeries constructor without passing data but only an index (#1798).

Notes on (optional) dependencies:

  • GeoPandas 0.9.0 dropped support for Python 3.5. Further, the minimum required versions are pandas 0.24, numpy 1.15 and shapely 1.6 and fiona 1.8.

  • The descartes package is no longer required for plotting polygons. This functionality is now included by default in GeoPandas itself, when matplotlib is available (#1677).

  • Fiona is now only imported when used in read_file/to_file. This means you can now force geopandas to install without fiona installed (although it is still a default requirement) (#1775).

  • Compatibility with the upcoming Shapely 1.8 (#1659, #1662, #1819).

Version 0.8.2 (January 25, 2021)#

Version 0.8.0 (June 24, 2020)#

Experimental: optional use of PyGEOS to speed up spatial operations (#1155). PyGEOS is a faster alternative for Shapely (being contributed back to a future version of Shapely), and is used in element-wise spatial operations and for spatial index in e.g. sjoin (#1343, #1401, #1421, #1427, #1428). See the installation docs for more info and how to enable it.

New features and improvements:

  • IO enhancements:

    • New GeoDataFrame.to_postgis() method to write to PostGIS database (#1248).

    • New Apache Parquet and Feather file format support (#1180, #1435)

    • Allow appending to files with GeoDataFrame.to_file (#1229).

    • Add support for the ignore_geometry keyword in read_file to only read the attribute data. If set to True, a pandas DataFrame without geometry is returned (#1383).

    • geopandas.read_file now supports reading from file-like objects (#1329).

    • GeoDataFrame.to_file now supports specifying the CRS to write to the file (#802). By default it still uses the CRS of the GeoDataFrame.

    • New chunksize keyword in geopandas.read_postgis to read a query in chunks (#1123).

  • Improvements related to geometry columns and CRS:

    • Any column of the GeoDataFrame that has a “geometry” dtype is now returned as a GeoSeries. This means that when having multiple geometry columns, not only the “active” geometry column is returned as a GeoSeries, but also accessing another geometry column (gdf["other_geom_column"]) gives a GeoSeries (#1336).

    • Multiple geometry columns in a GeoDataFrame can now each have a different CRS. The global gdf.crs attribute continues to returns the CRS of the “active” geometry column. The CRS of other geometry columns can be accessed from the column itself (eg gdf["other_geom_column"].crs) (#1339).

    • New set_crs() method on GeoDataFrame/GeoSeries to set the CRS of naive geometries (#747).

  • Improvements related to plotting:

    • The y-axis is now scaled depending on the center of the plot when using a geographic CRS, instead of using an equal aspect ratio (#1290).

    • When passing a column of categorical dtype to the column= keyword of the GeoDataFrame plot(), we now honor all categories and its order (#1483). In addition, a new categories keyword allows to specify all categories and their order otherwise (#1173).

    • For choropleths using a classification scheme (using scheme=), the legend_kwds accept two new keywords to control the formatting of the legend: fmt with a format string for the bin edges (#1253), and labels to pass fully custom class labels (#1302).

  • New covers() and covered_by() methods on GeoSeries/GeoDataframe for the equivalent spatial predicates (#1460, #1462).

  • GeoPandas now warns when using distance-based methods with data in a geographic projection (#1378).

Deprecations:

  • When constructing a GeoSeries or GeoDataFrame from data that already has a CRS, a deprecation warning is raised when both CRS don’t match, and in the future an error will be raised in such a case. You can use the new set_crs method to override an existing CRS. See the docs.

  • The helper functions in the geopandas.plotting module are deprecated for public usage (#656).

  • The geopandas.io functions are deprecated, use the top-level read_file and to_file instead (#1407).

  • The set operators (&, |, ^, -) are deprecated, use the intersection(), union(), symmetric_difference(), difference() methods instead (#1255).

  • The sindex for empty dataframe will in the future return an empty spatial index instead of None (#1438).

  • The objects keyword in the intersection method of the spatial index returned by the sindex attribute is deprecated and will be removed in the future (#1440).

Bug fixes:

  • Fix the total_bounds() method to ignore missing and empty geometries (#1312).

  • Fix geopandas.clip when masking with non-overlapping area resulting in an empty GeoDataFrame (#1309, #1365).

  • Fix error in geopandas.sjoin when joining on an empty geometry column (#1318).

  • CRS related fixes: pandas.concat preserves CRS when concatenating GeoSeries objects (#1340), preserve the CRS in geopandas.clip (#1362) and in GeoDataFrame.astype (#1366).

  • Fix bug in GeoDataFrame.explode() when ‘level_1’ is one of the column names (#1445).

  • Better error message when rtree is not installed (#1425).

  • Fix bug in GeoSeries.equals() (#1451).

  • Fix plotting of multi-part geometries with additional style keywords (#1385).

And we now have a Code of Conduct!

GeoPandas 0.8.0 is the last release to support Python 3.5. The next release will require Python 3.6, pandas 0.24, numpy 1.15 and shapely 1.6 or higher.

Version 0.7.0 (February 16, 2020)#

Support for Python 2.7 has been dropped. GeoPandas now works with Python >= 3.5.

The important API change of this release is that GeoPandas now requires PROJ > 6 and pyproj > 2.2, and that the .crs attribute of a GeoSeries and GeoDataFrame no longer stores the CRS information as a proj4 string or dict, but as a pyproj.CRS object (#1101).

This gives a better user interface and integrates improvements from pyproj and PROJ 6, but might also require some changes in your code. Check the migration guide in the documentation.

Other API changes;

  • The GeoDataFrame.to_file method will now also write the GeoDataFrame index to the file, if the index is named and/or non-integer. You can use the index=True/False keyword to overwrite this default inference (#1059).

New features and improvements:

  • A new geopandas.clip function to clip a GeoDataFrame to the spatial extent of another shape (#1128).

  • The geopandas.overlay function now works for all geometry types, including points and linestrings in addition to polygons (#1110).

  • The plot() method gained support for missing values (in the column that determines the colors). By default it doesn’t plot the corresponding geometries, but using the new missing_kwds argument you can specify how to style those geometries (#1156).

  • The plot() method now also supports plotting GeometryCollection and LinearRing objects (#1225).

  • Added support for filtering with a geometry or reading a subset of the rows in geopandas.read_file (#1160).

  • Added support for the new nullable integer data type of pandas in GeoDataFrame.to_file (#1220).

Bug fixes:

  • GeoSeries.reset_index() now correctly results in a GeoDataFrame instead of DataFrame (#1252).

  • Fixed the geopandas.sjoin function to handle MultiIndex correctly (#1159).

  • Fixed the geopandas.sjoin function to preserve the index name of the left GeoDataFrame (#1150).

Version 0.6.3 (February 6, 2020)#

Small bug-fix release:

  • Compatibility with Shapely 1.7 and pandas 1.0 (#1244).

  • Fix GeoDataFrame.fillna to accept non-geometry values again when there are no missing values in the geometry column. This should make it easier to fill the numerical columns of the GeoDataFrame (#1279).

Version 0.6.2 (November 18, 2019)#

Small bug-fix release fixing a few regressions:

  • Fix a regression in passing an array of RRB(A) tuples to the .plot() method (#1178, #1211).

  • Fix the bounds and total_bounds attributes for empty GeoSeries, which also fixes the repr of an empty or all-NA GeoSeries (#1184, #1195).

  • Fix filtering of a GeoDataFrame to preserve the index type when ending up with an empty result (#1190).

Version 0.6.1 (October 12, 2019)#

Small bug-fix release fixing a few regressions:

  • Fix astype when converting to string with Multi geometries (#1145) or when converting a dataframe without geometries (#1144).

  • Fix GeoSeries.fillna to accept np.nan again (#1149).

Version 0.6.0 (September 27, 2019)#

Important note! This will be the last release to support Python 2.7 (#1031)

API changes:

  • A refactor of the internals based on the pandas ExtensionArray interface (#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).

  • The missing value handling has been changed to now separate the concepts of missing geometries and empty geometries (#601, 1062). In practice this means that (see the docs 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).

  • Addition of a GeoDataFrame.rename_geometry method to easily rename the active geometry column (#1053).

  • Addition of geopandas.show_versions() function, which can be used to give an overview of the installed libraries in bug reports (#899).

  • The legend_kwds keyword of the plot() method can now also be used to specify keywords for the color bar (#1102).

  • Performance improvement in the sjoin() operation by re-using existing spatial index of the input dataframes, if available (#789).

  • Updated documentation to work with latest version of geoplot and contextily (#1044, #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).

  • The GeoDataFrame.astype() method now correctly returns a GeoDataFrame if the geometry column is preserved (#1009).

  • The to_crs method now uses always_xy=True to ensure correct lon/lat order handling for pyproj>=2.2.0 (#1122).

  • Fixed passing list-like colors in the plot() method in case of “multi” geometries (#1119).

  • Fixed the coloring of shapes and colorbar when passing a custom norm in the plot() method (#1091, #1089).

  • Fixed GeoDataFrame.to_file to preserve VFS file paths (e.g. when a “s3://” path is specified) (#1124).

  • Fixed failing case in geopandas.sjoin with empty geometries (#1138).

In addition, the minimum required versions of some dependencies have been increased: GeoPandas now requirs pandas >=0.23.4 and matplotlib >=2.0.1 (#1002).

Version 0.5.1 (July 11, 2019)#

  • Compatibility with latest mapclassify version 2.1.0 (#1025).

Version 0.5.0 (April 25, 2019)#

Improvements:

  • Significant performance improvement (around 10x) for GeoDataFrame.iterfeatures, which also improves GeoDataFrame.to_file (#864).

  • File IO enhancements based on Fiona 1.8:

    • Support for writing bool dtype (#855) and datetime dtype, if the file format supports it (#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, #867, #870).

  • Compatibility with pyproj >= 2 (#962).

  • A new geopandas.points_from_xy() helper function to convert x and y coordinates to Point objects (#896).

  • The buffer and interpolate methods now accept an array-like to specify a variable distance for each geometry (#781).

  • Addition of a relate method, corresponding to the shapely method that returns the DE-9IM matrix (#853).

  • Plotting improvements:

    • Performance improvement in plotting by only flattening the geometries if there are actually ‘Multi’ geometries (#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).

    • 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).

  • Changed the default provider in geopandas.tools.geocode from Google (now requires an API key) to Geocode.Farm (#907, #975).

Bug fixes:

  • Remove the edge in the legend marker (#807).

  • Fix the align method to preserve the CRS (#829).

  • Fix geopandas.testing.assert_geodataframe_equal to correctly compare left and right dataframes (#810).
