Clip (Coverage)


Uses the outside polygon boundary of the clip coverage to cookie-cut features and attributes from the input coverage.

Clip_arc (in_cover, clip_cover, out_cover, {feature_type}, {fuzzy_tolerance})
ParameterExplanationData Type

The coverage containing features to be clipped.


The coverage whose outer polygon defines the clipping region.


The coverage to be created. The output coverage cannot already exist.


The feature class to be clipped:

  • POLYPolygons and region subclasses are clipped and a PAT is saved. Label points for remaining polygons are moved only if their original location falls outside the clipping boundary. Route systems are ignored.
  • LINEArcs are clipped, and an AAT is saved. Route systems are maintained.
  • POINTPoints are clipped, and a PAT is saved.
  • NETPolygons and arcs are clipped, and their PAT and AAT are saved. Route systems and regions are maintained and clipped.
  • LINKArcs and points are clipped, and their AAT and PAT are saved. Route systems are maintained.
  • RAWPoints, arcs, and annotation in a coverage with or without topology (no attribute files) are clipped. Route systems are maintained, but regions, PAT, and AAT are not saved.

The minimum distance between coordinates in the output coverage. By default, the minimum fuzzy tolerance value from the input coverage and erase coverage is used.

Code Sample

Clip example (stand-alone script)

The following stand-alone script demonstrates how to create a new coverage that contains the clipped out area of a larger coverage.

# Name:
# Description: Clips a subset out of a polygon coverage.
# Requirements: ArcInfo Workstation
# Author: ESRI

# Import system modules
import arcpy
from arcpy import env

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

# Set local variables
inCover = "tongass1"
clipCover = "tong_basin4"
outCover = "C:/output/basin4"
featureType = "POLY"

# Execute Clip
arcpy.Clip_arc(inCover, clipCover, outCover, featureType, "")
