We are happy to announce the release of GeoPandas 0.2. It is a major release, accumulating work of the past two years. Thanks to Kelsey Kjordhal for the release, and to all the contributors for making this release possible.
See the revamped documentation: http://geopandas.readthedocs.io/en/stable/ If you are using Anaconda/miniconda, you can install it with conda from the conda-forge channel: conda install -c conda-forge geopandas Alternatively, you can also install it with pip (assuming the dependencies are installed): pip install geopandas 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 geometries to shapely. GeoPandas enables you to easily do operations in python that would otherwise require a spatial database such as PostGIS. What is new? ========== 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.ix`` 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).
