Summary
Extracts selected features from an input coverage and stores them in the output coverage.
Features are selected for extraction based on logical expressions or by applying the criteria contained in a selection file. Any item, including redefined items, in the specified feature attribute table of the Input coverage can be used.
Usage
When using the same input coverage and output coverage for feature classes Anno, Section, Route, or Region, the output feature class subclass name must be different from the input feature class subclass name.
Use of indexed items can speed up the logical selection process. You can use the Index Item tool to create an attribute index.
The same subclass names may be specified when the Output Coverage is not the same as the Input Coverage.

Syntax
Reselect_arc (in_cover, out_cover, info_express, {in_feature_type}, {selection_file}, {out_feature_type})
Parameter | Explanation | Data Type |
in_cover | The input coverage containing the features that will be selected. | Coverage |
out_cover | The output coverage containing the selected features. | Coverage |
info_express [info_express,...] | Write a query that contains one or more logical expressions to select features from the input coverage. Each expression takes one of the following forms:
| INFO Expression |
in_feature_type (Optional) | The feature class to select:
| String |
selection_file (Optional) | A preexisting file that identifies the features to select. | File |
out_feature_type (Optional) | The feature class in the output coverage. This must be the same as that of the input feature class, with this exception: When the input feature class is an Anno, Route, Section, or Region subclass and the output coverage is the same as the Input coverage, the output feature class must have a different subclass name. | String |
Code sample
Reselect example (stand-alone script)
The following stand-alone script demonstrates how to select features from a coverage.
# Name: Reselect_Example.py
# Description: Selects streams of interest from a larger stream coverage
# Requirements: ArcInfo Workstation
# Import system modules
import arcpy
from arcpy import env
# Set environment settings
env.workspace = "C:/data"
# Set local variables
inCover = "stream"
outCover = "C:/output/studystreams"
infoExpress = ["RESELECT stream_name CN 'AQUEDUCT'",
"NSELECT",
"RESELECT stream_order > 3",
"ASELECT length > 10000"]
inFeatureType = "LINE"
# Execute Reselect
arcpy.Reselect_arc(inCover, outCover, infoExpress, inFeatureType, "", "")
