geopandas 0.5.0

v0.5.0

on Python PyPI

GeoPandas 0.5.0 includes some improvements for writing files with fiona (better performance, better support for data types and mixed geometry types), along with many other new features and bug fixes, see the full list below.

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).
• Fix in choropleth mapping when the values contain missing values (#877).
• Better error message in sjoin if the input is not a GeoDataFrame (#842).
• Fix in read_postgis to handle nullable (missing) geometries (#856).
• Correctly passing through the parse_dates keyword in read_postgis to the underlying pandas method (#860).
• Fixed the shape of Antarctica in the included demo dataset 'naturalearth_lowres'
  (by updating to the latest version) (#804).
