- 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)
