teradataml.geospatial.geodataframe.GeoDataFrame.min_z
DESCRIPTION:
    Returns the minimum Z coordinate of a Geometry value.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    All Geometry types.
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrame
    Resultant column contains a NULL, if the Geometry is an empty set.
 
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", "polygons", "linestrings"])
    gdf
 
    # Example 1: Get the minimum Z coordinate of all Polygon geometries in column 'polygons'.
    # 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 'polygons'. Thus, no need to set it again.
