- teradataml.geospatial.geodataframecolumn.GeoDataFrameColumn.interiors = interiors(self, position)
- DESCRIPTION:
Returns the specified interior ring of a Geometry type that represents
an ST_Polygon value.
PARAMETERS:
position:
Required Argument.
Specifies a value for the requested interior ring, where the
position of the first interior ring is 1.
Types: int, str, ColumnExpression
SUPPORTED GEOMETRY TYPES:
ST_Polygon
Note:
This method can be called on 3D geometries (those that include Z
coordinates). However, the Z coordinate is ignored in method
calculations. Consequently, any Z coordinates returned by this
method should be ignored. Teradata recommends using the make_2D()
method to strip out the Z coordinates of the return value.
RAISES:
TypeError, ValueError, TeradataMlException
RETURNS:
GeoDataFrameColumn containing ST_LineString 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 interior ring specified at 1st index for polygons.
# Filter the data to select few rows and couple of columns (skey and polygons).
polygons = geodf.select(["skey", "polygons"])[geodf.skey.isin([1002, 1004])]
geo_interiors = polygons.geometry.interiors(position=1)
polygons.assign(res = geo_interiors)
# Example 2: Filter the rows where the interior ring specified at 1st index for polygons
# is same as the specified LineString GeometryType object.
# Create an object of LineString GeometryType.
l1 = LineString([(5, 5), (5, 10), (10, 10), (10, 5), (5, 5)])
# Execute the interiors() function on 'polygons' column.
geo_interiors = polygons.geometry.interiors(position=1)
polygons[geo_interiors == l1]
