teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.geom_type
DESCRIPTION:
    Returns the Geometry type of the Geometry value.
 
PARAMETERS:
    None
 
SUPPORTED GEOMETRY TYPES:
    All Geometry types.
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrameColumn
    Resultant column contains any of the following strings:
        * 'ST_Point'
        * 'ST_LineString'
        * 'ST_Polygon'
        * 'ST_MultiPoint'
        * 'ST_MultiLineString'
        * 'ST_MultiPolygon'
        * 'ST_GeomCollection'
        * 'GeoSequence'
 
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 geometry type of all geometries in column 'polygons'.
    gdf.assign(res=gdf.polygons.geom_type)
 
    # Example 2: Filter the rows where geometry type is 'ST_MultiPolygon'.
    gdf[gdf.polygons.geom_type == "ST_MultiPolygon"]
