teradataml.geospatial.geodataframe.GeoDataFrame.z
DESCRIPTION:
    Get the Z coordinate of an ST_Point value.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    ST_Point
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrame
 
EXAMPLES:
    from teradataml import GeoDataFrame, load_example_data
    # Load example data.
    load_example_data("geodataframe", "sample_shapes")
    # Create a GeoDataFrame.
    gdf = GeoDataFrame("sample_shapes")
    gdf = gdf.select(["skey", "points", "linestrings"])[(gdf.points.is_3D == 1) &
    (gdf.points.geom_type == "ST_Point")]
    gdf
 
    # Example 1: Get the Z coordinate of all geometries in column "points".
    # Let's check where the GeoDataFrame.geometry property points to.
    print(gdf.geometry.name)
    # Note: By default, GeoDataFrame.geometry property points to the first geometry column,
    #       in this case it is "points". Thus, no need to set it again.
