Improvements:

  • Pass keywords to control legend behavior (legend_kwds) to plot (#434)
  • Add basic support for reading remote datasets in read_file (#531)
  • Pass kwargs for buffer operation on GeoSeries (#535)
  • Expose all geopy services as options in geocoding (#550)

Bug fixes :

  • Ensure that colorbars are plotted on the correct axis (#523)

Version 0.3.0 (August 29, 2017)

Improvements:

  • Improve plotting performance using matplotlib.collections (#267)
  • Improve default plotting appearance. The defaults now follow the new matplotlib defaults (#318, #502, #510)
  • Provide access to x/y coordinates as attributes for Point GeoSeries (#383)
  • Make the NYBB dataset available through geopandas.datasets (#384)
  • Enable sjoin on non-integer-index GeoDataFrames (#422)
  • Add cx indexer to GeoDataFrame (#482)
  • GeoDataFrame.from_features now also accepts a Feature Collection (#225, #507)
  • Use index label instead of integer id in output of iterfeatures and to_json (#421)
  • Return empty data frame rather than raising an error when performing a spatial join with non overlapping geodataframes (#335)

Bug fixes:

  • Compatibility with shapely 1.6.0 (#512)
  • Fix fiona.filter results when bbox is not None (#372)
  • Fix dissolve to retain CRS (#389)
  • Fix cx behavior when using index of 0 (#478)
  • Fix display of lower bin in legend label of choropleth plots using a PySAL scheme (#450)

Version 0.2.0

Improvements:

  • Complete overhaul of the documentation
  • Addition of overlay to perform spatial overlays with polygons (#142)
  • Addition of sjoin to perform spatial joins (#115, #145, #188)
  • Addition of __geo_interface__ that returns a python data structure to represent the GeoSeries as a GeoJSON-like FeatureCollection (#116) and iterfeatures method (#178)
  • Addition of the explode (#146) and dissolve (#310, #311) methods.
  • Addition of the sindex attribute, a Spatial Index using the optional dependency rtree (libspatialindex) that can be used to speed up certain operations such as overlays (#140, #141).
  • Addition of the GeoSeries.cx coordinate indexer to slice a GeoSeries based on a bounding box of the coordinates (#55).
  • Improvements to plotting: ability to specify edge colors (#173), support for the vmin, vmax, figsize, linewidth keywords (#207), legends for chloropleth plots (#210), color points by specifying a colormap (#186) or a single color (#238).
  • Larger flexibility of to_crs, accepting both dicts and proj strings (#289)
  • Addition of embedded example data, accessible through geopandas.datasets.get_path.

API changes:

  • In the plot method, the axes keyword is renamed to ax for consistency with pandas, and the colormap keyword is renamed to cmap for consistency with matplotlib (#208, #228, #240).

Bug fixes:

  • Properly handle rows with missing geometries (#139, #193).
  • Fix GeoSeries.to_json (#263).
  • Correctly serialize metadata when pickling (#199, #206).
  • Fix merge and concat to return correct GeoDataFrame (#247, #320, #322).
