teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.dimension
DESCRIPTION:
    Returns the dimension of the Geometry type.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    All Geometry types.
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrameColumn
    Resultant column contains:
        * 0, for a 0-dimensional geometry
        * 1, for a 1D geometry
        * 2, for a 2D geometry
        * -1, if the input geometry 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")
    gdf = gdf.select(["skey", "polygons", "linestrings"])
    gdf
 
    # Example 1: Get the dimension of all geometries in column 'polygons'.
    gdf.assign(res=gdf.polygons.dimension)
 
    # Example 2: Filter the rows where dimension of geometry (polygon) is equal to 2.
    gdf[gdf.polygons.dimension == 2]
