- teradataml.geospatial.geodataframe.GeoDataFrame.buffer = buffer(self, distance)
- DESCRIPTION:
Returns all points whose distance from a Geometry value is less than or
equal to a specified distance.
Note:
* The "distance" argument is measured in the linear units of measure in
the spatial reference system of the Geometry value.
PARAMETERS:
distance:
Required Argument.
Specifies the distance from the geometry value to the buffer.
Types: float, str, ColumnExpression
SUPPORTED GEOMETRY TYPES:
All Geometry types
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:
GeoDataFrame with result column containing Geometry values
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)
# Let's select only skey and points columns from GeoDataFrame.
points = geodf.select(["skey", "points"])
# Example 1: Get all the points with distance less than or equal to 2.8 from the geometries
# specified in column 'points'
points.buffer(2.8)
