Indexing and Selecting Data¶
GeoPandas inherits the standard pandas methods for indexing/selecting data. This includes label based indexing with loc
and integer position based indexing with iloc
, which apply to both GeoSeries
and GeoDataFrame
objects. For more information on indexing/selecting, see the pandas documentation.
In addition to the standard pandas methods, GeoPandas also provides
coordinate based indexing with the cx
indexer, which slices using a bounding
box. Geometries in the GeoSeries
or GeoDataFrame
that intersect the
bounding box will be returned.
Using the world
dataset, we can use this functionality to quickly select all
countries whose boundaries extend into the southern hemisphere.
In [1]: world = geopandas.read_file(geopandas.datasets.get_path('naturalearth_lowres'))
In [2]: southern_world = world.cx[:, :0]
In [3]: southern_world.plot(figsize=(10, 3));
