teradataml.geospatial.geodataframe.GeoDataFrame.set_srid = set_srid(self, srid)
DESCRIPTION:
    Set the spatial reference system identifier of the Geometry
    value.
 
PARAMETERS:
    srid:
        Required Argument.
        Specifies a value for the spatial reference system identifier.
        Types: int, str, ColumnExpression
 
SUPPORTED GEOMETRY TYPES:
    All Geometry types.
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    GeoDataFrame
    Resultant column contains the Geometry with the spatial reference system identifier set
    to the specified spatial reference system.
 
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.
    geodf = GeoDataFrame("sample_shapes")
    print(geodf)
    
    # Example 1: Set the spatial reference system identifier for the geometries in column 'geosequence'.
    # Let's select only few columns from GeoDataFrame.
    geoseq = geodf.select(["skey", "geosequence"])[geodf.skey.isin([1001, 1002])]
    geoseq.set_srid(srid=20)
