- teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.point_on_surface = point_on_surface(self)
- DESCRIPTION:
Returns a point that is guaranteed to spatially intersect an ST_Polygon,
or at least one of the component polygons of an ST_MultiPolygon.
PARAMETERS:
None
SUPPORTED GEOMETRY TYPES:
ST_Polygon and ST_MultiPolygon
Note:
This method can be called on 3D geometries (those that include Z
coordinates). However, the Z coordinate is dropped, and only x and y
coordinates are returned.
RAISES:
TypeError, ValueError, TeradataMlException
RETURNS:
GeoDataFrameColumn containing Geometry values
EXAMPLES:
from teradataml import GeoDataFrame, load_example_data
from teradataml import Point, LineString, Polygon, GeometryCollection
# Load example data.
load_example_data("geodataframe", "sample_shapes")
# Create a GeoDataFrame.
geodf = GeoDataFrame("sample_shapes")
print(geodf)
# Example 1: Get the point in polygon geometries that is guaranteed to spatially intersect.
# Let's select only few columns from GeoDataFrame.
pols = geodf.select(["skey", "polygons"])[geodf.skey.isin([1001, 1002, 1003])]
pols.assign(res = pols.polygons.point_on_surface())
