teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.is_closed_3D
DESCRIPTION:
    Tests whether a 3D LineString or 3D MultiLineString is closed, taking
    into account the Z coordinates in the calculation.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    LineString and MultiLineString types that include Z coordinates
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrameColumn
    Resultant column contains:
        * 1, if the 3D LineString or 3D MultiLineString is closed.
        * 0, if the 3D LineString or 3D MultiLineString is not closed or is empty.
 
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")
    # Select few columns and filter rows containing only 3D geometries in 'linestrings' column.
    gdf = gdf.select(["skey", "polygons", "linestrings"])[gdf.linestrings.is_3D == 1]
    gdf
 
    # Example 1: Check if 3D geometries in column "linestings" is are closed or not.
    gdf.assign(res=gdf.linestrings.is_closed_3D)
 
    # Example 2: Filter the rows where 3D geometry in column 'linestrings' is not closed.
    gdf[gdf.linestrings.is_closed_3D != 1]
