teradataml.geospatial.geodataframe.GeoDataFrame.line_interpolate_point = line_interpolate_point(self, proportion)
DESCRIPTION:
    Returns a point interpolated along a Geometry type that represents an
    ST_LineString or GeoSequence value, given a proportional distance along
    that line.
 
PARAMETERS:
    proportion:
        Required Argument.
        Specifies a value between 0 and 1 that represents the fraction of the
        total 2-dimensional length of the ST_LineString where the point must
        be located.
        Types: float, str, ColumnExpression
 
SUPPORTED GEOMETRY TYPES:
    ST_LineString and GeoSequence
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrame with result column containing ST_Point 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 point interpolated along the ST_Linestring geometries
    #            in column 'linestrings'.
    # Let's select only few columns from GeoDataFrame and filter rows which contains
    # only ST_Linestring geometries.
    lines = geodf.select(["skey", "linestrings"])[geodf.linestrings.geom_type == "ST_Linestring"]
    lines.line_interpolate_point(proportion=0.28)
