    """A GeoDataFrame object is a pandas.DataFrame that has one or more columns
    containing geometry.

    In addition to the standard DataFrame constructor arguments,
    GeoDataFrame also accepts the following keyword arguments:

    Parameters
    ----------
    crs : value (optional)
        Coordinate Reference System of the geometry objects. Can be anything accepted by
        :meth:`pyproj.CRS.from_user_input() <pyproj.crs.CRS.from_user_input>`,
        such as an authority string (eg "EPSG:4326") or a WKT string.
    geometry : str or array-like (optional)
        Value to use as the active geometry column.
        If str, treated as column name to use. If array-like, it will be
        added as new column named 'geometry' on the GeoDataFrame and set as the
        active geometry column.

        Note that if ``geometry`` is a (Geo)Series with a
        name, the name will not be used, a column named "geometry" will still be
        added. To preserve the name, you can use :meth:`~GeoDataFrame.rename_geometry`
        to update the geometry column name.

    Examples
    --------
    Constructing GeoDataFrame from a dictionary.

    >>> from shapely.geometry import Point
    >>> d = {'col1': ['name1', 'name2'], 'geometry': [Point(1, 2), Point(2, 1)]}
    >>> gdf = geopandas.GeoDataFrame(d, crs="EPSG:4326")
    >>> gdf
        col1     geometry
    0  name1  POINT (1 2)
    1  name2  POINT (2 1)

    Notice that the inferred dtype of 'geometry' columns is geometry.

    >>> gdf.dtypes
    col1          object
    geometry    geometry
    dtype: object

    Constructing GeoDataFrame from a pandas DataFrame with a column of WKT geometries:

    >>> import pandas as pd
    >>> d = {'col1': ['name1', 'name2'], 'wkt': ['POINT (1 2)', 'POINT (2 1)']}
    >>> df = pd.DataFrame(d)
    >>> gs = geopandas.GeoSeries.from_wkt(df['wkt'])
    >>> gdf = geopandas.GeoDataFrame(df, geometry=gs, crs="EPSG:4326")
    >>> gdf
        col1          wkt     geometry

            if the index is just arbitrary row numbers.

            If the CRS is set on the active geometry column it is exported as
            WGS84 (EPSG:4326) to meet the `2016 GeoJSON specification
            <https://tools.ietf.org/html/rfc7946>`_.
            Set to True to force re-projection and set to False to ignore CRS. False by
            default.

        Notes
        -----
        The remaining *kwargs* are passed to json.dumps().

        Missing (NaN) values in the GeoDataFrame can be represented as follows:

        - ``null``: output the missing entries as JSON null.
        - ``drop``: remove the property from the feature. This applies to each
          feature individually so that features may have different properties.
        - ``keep``: output the missing entries as NaN.

        If the GeoDataFrame has a defined CRS, its definition will be included
        in the output unless it is equal to WGS84 (default GeoJSON CRS) or not
        possible to represent in the URN OGC format, or unless ``to_wgs84=True``
        is specified.

        Examples
        --------
        >>> from shapely.geometry import Point
        >>> d = {'col1': ['name1', 'name2'], 'geometry': [Point(1, 2), Point(2, 1)]}
        >>> gdf = geopandas.GeoDataFrame(d, crs="EPSG:3857")
        >>> gdf

        geometry_encoding : {'WKB', 'geoarrow' }, default 'WKB'
            The GeoArrow encoding to use for the data conversion.
        interleaved : bool, default True
            Only relevant for 'geoarrow' encoding. If True, the geometries'
            coordinates are interleaved in a single fixed size list array.

            If False, return 2D geometries. If True, include the third dimension
            in the output (if a geometry has no third dimension, the z-coordinates
            will be NaN). By default, will infer the dimensionality from the

            Name of the compression to use. Use ``None`` for no compression.
        geometry_encoding : {'WKB', 'geoarrow'}, default 'WKB'
            The encoding to use for the geometry columns. Defaults to "WKB"
            for maximum interoperability. Specify "geoarrow" to use one of the
            native GeoArrow-based single-geometry type encodings.
            Note: the "geoarrow" option is part of the newer GeoParquet 1.1
            specification, should be considered as experimental, and may not
            be supported by all readers.
        write_covering_bbox : bool, default False
            Writes the bounding box column for each row entry with column
            name 'bbox'. Writing a bbox column can be computationally
            expensive, but allows you to specify a `bbox` in :
            func:`read_parquet` for filtered reading.
            Note: this bbox column is part of the newer GeoParquet 1.1
            specification and should be considered as experimental. While
            writing the column is backwards compatible, using it for filtering
            may not be supported by all readers.
        schema_version : {'0.1.0', '0.4.0', '1.0.0', '1.1.0', None}
            GeoParquet specification version; if not provided, will default to

            The write mode, 'w' to overwrite the existing file and 'a' to append.
            Not all drivers support appending. The drivers that support appending
            are listed in fiona.supported_drivers or

            The underlying library that is used to write the file. Currently, the
            supported options are "pyogrio" and "fiona". Defaults to "pyogrio" if
            installed, otherwise tries "fiona".
        metadata : dict[str, str], default None
            Optional metadata to be stored in the file. Keys and values must be
            strings. Supported only for "GPKG" driver.
        **kwargs :
            Keyword args to be passed to the engine, and can be used to write
            to multi-layer data, store data within archives (zip files), etc.
            In case of the "pyogrio" engine, the keyword arguments are passed to
            `pyogrio.write_dataframe`. In case of the "fiona" engine, the keyword

        The format drivers will attempt to detect the encoding of your data, but
        may fail. In this case, the proper encoding can be specified explicitly

        Dissolve geometries within `groupby` into single observation.

        Observations associated with each `groupby` group will be aggregated
        using the `aggfunc`.

        Parameters
        ----------
        by : str or list-like, default None
            Column(s) whose values define the groups to be dissolved. If None,
            the entire GeoDataFrame is considered as a single group. If a list-like
            object is provided, the values in the list are treated as categorical
            labels, and polygons will be combined based on the equality of
            these categorical labels.
        aggfunc : function or string, default "first"
            Aggregation function for manipulation of data associated
            with each group. Passed to pandas `groupby.agg` method.
            Accepted combinations are:

            - function
            - string function name
            - list of functions and/or function names, e.g. [np.sum, 'mean']
            - dict of axis labels -> functions, function names or list of such.
        as_index : boolean, default True
            If true, groupby columns become index of result.
        level : int or str or sequence of int or sequence of str, default None
            If the axis is a MultiIndex (hierarchical), group by a
            particular level or levels.
        sort : bool, default True
            Sort group keys. Get better performance by turning this off.
            Note this does not influence the order of observations within
            each group. Groupby preserves the order of rows within each group.
        observed : bool, default False
            This only applies if any of the groupers are Categoricals.
            If True: only show observed values for categorical groupers.
            If False: show all values for categorical groupers.
        dropna : bool, default True
            If True, and if group keys contain NA values, NA values
            together with row/column will be dropped. If False, NA
            values will also be treated as the key in groups.
        method : str (default ``"unary"``)
            The method to use for the union. Options are:

            * ``"unary"``: use the unary union algorithm. This option is the most robust
              but can be slow for large numbers of geometries (default).
            * ``"coverage"``: use the coverage union algorithm. This option is optimized
              for non-overlapping polygons and can be significantly faster than the
              unary union algorithm. However, it can produce invalid geometries if the
              polygons overlap.
            * ``"disjoint_subset:``: use the disjoint subset union algorithm. This
              option is optimized for inputs that can be divided into subsets that do
              not intersect. If there is only one such subset, performance can be
              expected to be worse than ``"unary"``.  Requires Shapely >= 2.1.


        grid_size : float, default None
            When grid size is specified, a fixed-precision space is used to perform the
            union operations. This can be useful when unioning geometries that are not
            perfectly snapped or to avoid geometries not being unioned because of
            `robustness issues <https://libgeos.org/usage/faq/#why-doesnt-a-computed-point-lie-exactly-on-a-line>`_.
            The inputs are first snapped to a grid of the given size. When a line
            segment of a geometry is within tolerance off a vertex of another geometry,
            this vertex will be inserted in the line segment. Finally, the result
            vertices are computed on the same grid. Is only supported for ``method``
            ``"unary"``. If None, the highest precision of the inputs will be used.
            Defaults to None.

        Upload GeoDataFrame into PostGIS database.

        This method requires SQLAlchemy and GeoAlchemy2, and a PostgreSQL
        Python driver (psycopg or psycopg2) to be installed.

        It is also possible to use :meth:`~GeoDataFrame.to_file` to write to a database.
        Especially for file geodatabases like GeoPackage or SpatiaLite this can be
        easier.

        Parameters
        ----------
        name : str
            Name of the target table.
        con : sqlalchemy.engine.Connection or sqlalchemy.engine.Engine
            Active connection to the PostGIS database.
        if_exists : {'fail', 'replace', 'append'}, default 'fail'
            How to behave if the table already exists:

            - fail: Raise a ValueError.
            - replace: Drop the table before inserting new values.
            - append: Insert new values to the existing table.
        schema : string, optional
            Specify the schema. If None, use default schema: 'public'.
        index : bool, default False
            Write DataFrame index as a column.
            Uses *index_label* as the column name in the table.
        index_label : string or sequence, default None
            Column label for index column(s).
            If None is given (default) and index is True,
            then the index names are used.
        chunksize : int, optional
            Rows will be written in batches of this size at a time.
            By default, all rows will be written at once.
        dtype : dict of column name to SQL type, default None
            Specifying the datatype for columns.
            The keys should be the column names and the values
            should be the SQLAlchemy types.

        Parameters
        ----------
        df : GeoDataFrame
        how : string, default 'inner'
            The type of join:

            * 'left': use keys from left_df; retain only left_df geometry column

            * 'inner': use intersection of keys from both dfs; retain only
              left_df geometry column

        predicate : string, default 'intersects'
            Binary predicate. Valid values are determined by the spatial index used.
            You can check the valid values in left_df or right_df as
            ``left_df.sindex.valid_query_predicates`` or
            ``right_df.sindex.valid_query_predicates``
        lsuffix : string, default 'left'
            Suffix to apply to overlapping column names (left GeoDataFrame).
        rsuffix : string, default 'right'
            Suffix to apply to overlapping column names (right GeoDataFrame).
        distance : number or array_like, optional
            Distance(s) around each input geometry within which to query the tree
            for the 'dwithin' predicate. If array_like, must be
            one-dimesional with length equal to length of left GeoDataFrame.
            Required if ``predicate='dwithin'``.
        on_attribute : string, list or tuple
            Column name(s) to join on as an additional join restriction on top
            of the spatial predicate. These must be found in both DataFrames.
            If set, observations are joined only if the predicate applies

        lsuffix : string, default 'left'
            Suffix to apply to overlapping column names (left GeoDataFrame).
        rsuffix : string, default 'right'
            Suffix to apply to overlapping column names (right GeoDataFrame).
        distance_col : string, default None
            If set, save the distances computed between matching geometries under a
            column of this name in the joined GeoDataFrame.
        exclusive : bool, optional, default False
            If True, the nearest geometries that are equal to the input geometry

            If True, return only geometries of original type in case of intersection
            resulting in multiple geometry types or GeometryCollections.
            If False, return all resulting geometries (potentially mixed types).
        sort : boolean, default False
            If True, the order of rows in the clipped GeoDataFrame will be preserved at
            small performance cost. If False the order of rows in the clipped
            GeoDataFrame will be random.

        Returns
        -------
        GeoDataFrame
            Vector data (points, lines, polygons) from the GeoDataFrame clipped to
            polygon boundary from mask.

        Currently only supports data GeoDataFrames with uniform geometry types,
        i.e. containing only (Multi)Polygons, or only (Multi)Points, or a
        combination of (Multi)LineString and LinearRing shapes.
        Implements several methods that are all effectively subsets of the union.

        See the User Guide page :doc:`../../user_guide/set_operations` for details.

        Parameters
        ----------
        right : GeoDataFrame
        how : string
            Method of spatial overlay: 'intersection', 'union',
            'identity', 'symmetric_difference' or 'difference'.
        keep_geom_type : bool
            If True, return only geometries of the same geometry type the GeoDataFrame
            has, if False, return all resulting geometries. Default is None,
            which will set keep_geom_type to True but warn upon dropping
            geometries.
        make_valid : bool, default True
            If True, any invalid input geometries are corrected with a call to
            make_valid(), if False, a `ValueError` is raised if any input geometries
            are invalid.

        -------
        df : GeoDataFrame
            GeoDataFrame with new set of polygons and attributes
