teradataml.geospatial.geodataframe.GeoDataFrame.envelope = envelope(self)
DESCRIPTION:
    Returns the bounding rectangle for the Geometry value.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    All Geometry types.
    Note:
        This method can be called on 3D geometries (those that include Z
        coordinates). However, the Z coordinate is dropped, and only x and y
        coordinates are returned.
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrame with result column containing Geometry values
 
EXAMPLES:
    from teradataml import GeoDataFrame, load_example_data
    from teradataml import Point, LineString, Polygon
    # Load example data.
    load_example_data("geodataframe", "sample_shapes")
    # Create a GeoDataFrame.
    geodf = GeoDataFrame("sample_shapes")
    print(geodf)
    
    # Example 1: Get the bounding rectangle for (ST_Point/ST_MultiPoint) geometries in column
    #            'points'.
    points_lines = geodf.select(["skey", "points", "linestrings"])
    points_lines.envelope()
 
    # Example 2: Get the bounding rectangle for (ST_Linestring/ST_MultiLinestring) geometries in column
    #            'linestrings'.
    # Set the geometry property of GeoDataFrame to point to 'linestrings' column.
    points_lines.geometry = points_lines.linestrings
    points_lines.envelope()
