Update IDs (Coverage)

Summary

Updates User-IDs in a coverage after they have been modified in a feature attribute table. The feature attribute table is used to determine the correct User-ID for each feature in the coverage. This value is recorded in all places where the feature User-ID is stored.

Usage

• Tools such as Add Item and Calculate Field can be used to add or modify User-IDs in a coverage's feature attribute table before Update IDs is used.

• If the Create Labels tool has been used to create new label points for coverage polygons, the polygon User-IDs stored in the coverage PAT are not equal to the new label point User-IDs. Create Labels stores the new label points and their User-IDs in the LAB file. Update IDs may be used to change the label point User-IDs to be equal to the User-IDs stored in the PAT.

• To change the User-IDs stored in the PAT to be equal to the label point User-IDs, use the Build tool.

• There is no NODE option because the Update IDs tool is not necessary after updating User-IDs in the NAT file.

Syntax

IDEdit_arc (in_cover, feature_type)

Parameter	Explanation	Data Type
in_cover	The coverage for which User-IDs have been modified.	Coverage
feature_type	Specifies the class of features for which User-IDs are to be updated. POLY —Polygon User-IDs will be updated. This is the default option. LINE —Arc User-IDs will be updated. POINT —Point User-IDs will be updated. ANNO.subclass —Annotation User-IDs will be updated.	String

Code Sample

IDEdit example (stand-alone script)

The following stand-alone script demonstrates how to update User-IDs in a coverage.

# Name: IDEdit_Example.py
# Description: Adds polygon labels, then updates the User-IDs for a 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 = "texas"
featureType = "POLY"

#Execute IDEdit
arcpy.IDEdit_arc(inCover, featureType)
