teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.end_point = end_point(self)
DESCRIPTION:
    Returns the end point of an ST_LineString or GeoSequence value.
    Note:
        *  This method returns a point having a Z coordinate if the input
          geometry is three-dimensional.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    ST_LineString and GeoSequence
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrameColumn
    Resultant column contains a NULL, if the Geometry is an empty set.
 
EXAMPLES:
    from teradataml import GeoDataFrame, load_example_data
    from teradataml import Point, LineString, Polygon, GeometryCollection
    # Load example data.
    load_example_data("geodataframe", "sample_shapes")
    # Create a GeoDataFrame.
    geodf = GeoDataFrame("sample_shapes")
    print(geodf)
 
    # Example 1: Get the end points of (ST_Linestring) geometries in column
    #            'linestrings'.
    # Process the GeoDataFrameColumn to select only two columns, skey and linestrings and filter the
    # rows where geometry type is ST_Linestring.
    lines = geodf.select(["skey", "linestrings"])[geodf.linestrings.geom_type == "ST_Linestring"]
    ep_expr = lines.geometry.end_point()
    lines.assign(res = ep_expr)
 
    # Example 2: Filter the rows where the end points of (ST_Linestring) geometries in column
    #            'linestrings' is same as the specified Point GeometryType object.
    # Create an object of Point GeometryType.
    p1 = Point(0, 1)
    # Execute the 'end_point()' on GeoDataFrameColumn pointed by geometry property and pass
    # the Point object created above to the slice filter.
    lines[lines.geometry.end_point() == p1]
