Point Node (Coverage)


Performs a spatial JOINITEM on the point coverage and the node coverage. It transfers the attributes from a point feature class to a node feature class. Each point feature in the point coverage is matched to the corresponding node feature in the node coverage. If any point is within the search radius of a node, the attributes are copied.

ParameterExplanationData Type

The coverage containing point features to be transferred.


An existing cover whose node attribute values will be updated or created if the NAT does not exist.


The maximum distance apart that points and nodes can be for the attributes of the point class to be transferred and recorded to the node coverage as a node class. The radius is given in coverage units. The default search radius is the width or height of the node coverage's BND divided by 100, whichever is larger.


Code Sample

PointNode example (stand-alone script)

The following stand-alone script demonstrates how to use the Point Node tool.

# Name: PointNode_Example.py
# Description: Performs PointNode on two coverages.
# Requirements: ArcInfo Workstation
# Author: ESRI

# Import system modules
import arcpy
from arcpy import env

# Set environment settings
env.workspace = "C:/data"

# Set local variables
pointCover = "wells142"
nodeCover = "county"
searchRadius =  3600

# Execute PointNode
arcpy.PointNode_arc(pointCover, nodeCover, searchRadius)
