teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.centroid
DESCRIPTION:
    Returns the mathematical centroid of an ST_Polygon or ST_MultiPolygon
    value.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    ST_Polygon or ST_MultiPolygon.
    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:
    GeoDataFrameColumn 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.
    gdf = GeoDataFrame("sample_shapes")
    gdf = gdf.select(["skey", "polygons", "linestrings"])[gdf.skey.isin([1001, 1002, 1003])]
    gdf
 
    # Example 1: Get the centroid of all Polygon geometries in column 'polygons'.
    gdf.assign(res=gdf.polygons.centroid)
