Geoprocessing tool that creates polygons from areas enclosed by line or polygon features.
Where one or more input features form a closed area, a new polygon feature will be constructed and written to the output feature class. The output attributes will vary depending on the Preserve attributes option on the dialog box (the attributes parameter in scripting) and the Label Features option on the dialog box (the label_features parameter in scripting).
When multiple feature classes or layers are specified in the list of input features, the order of the entries in the list does not affect the output feature type, but the spatial reference of the top entry on the tool dialog box (the first entry in scripting) in the list will be used during processing and set to the output.
Parametric (true) curves in the input features will remain true curves in the output polygons, even if they are split. This does not apply to shapefile data.
The Preserve attributes parameter (the attributes parameter in scripting) does not work and should not be used. It will not be removed for backward compatibility of scripts or models. The output attribute schema and field values for certain input combinations may be produced as described below; most of them are unintended.
If the Preserve attributes option on the dialog box is checked (the attributes parameter is set to ATTRIBUTES in scripting), the output attributes schema and field values will depend on whether the label features (points) are provided in the following ways:
If the Preserve attributes option on the dialog box is unchecked (the attributes parameter is set to NO_ATTRIBUTES in scripting), the input attribute schemas will be written to the output, but the attribute values will be empty. If you do not want any attributes on the output polygon feature class, supply a point feature class that has no attributes for the Label Features parameter.
Where input polygon features are broken into smaller output polygon features, the Identity tool can be used to transfer attributes from the input polygon features to the resulting polygon features.
This tool will use a tiling process to handle very large datasets for better performance and scalability. For more details, see Geoprocessing with large datasets.
| Parameter | Explanation |
|---|---|
| in_features | The input features that can be line or polygon, or both. |
| out_feature_class (Optional) | The output polygon feature class. |
| attributes (Optional) | Specifies whether to preserve the input attribute schema or the attributes from label features in the output feature class, or omit any input attributes in the output feature class. This parameter does not work and should not be used. It will not be removed for backward compatibility of scripts or models. The output attribute schema and field values for certain input combinations may be produced as described in the usage notes; most of them are unintended. Checked—Preserves the input attribute schema or the attribures from label features, if provided, in the output features. This is the default. Unchecked—Omits any input attributes in the output feature class. |
| esri_out_feature_service_name (Optional) | The name of the optional feature service to create on the federated server containing the result of this tool. If no name is specified an output feature service will not be created. |
FeatureToPolygon Example 1 (Python window)
The following Python window script demonstrates how to use the FeatureToPolygon function in immediate mode.
import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.FeatureToPolygon_management(["mainroads.shp","streets.shp"],
"c:/output/output.gdb/streetblocks",
"", "NO_ATTRIBUTES", "")
FeatureToPolygon Example 2 (stand-alone script)
The following stand-alone script is a simple example of how to apply the FeatureToPolygon function in a scripting environment.
# Name: FeatureToPolygon_Example2.py
# Description: Use FeatureToPolygon function to construct habitat areas
# from park boundaries and rivers.
# Author: ESRI
# import system modules
import arcpy
from arcpy import env
# Set environment settings
env.workspace = "C:/data/parks_analysis.gdb"
# Set local parameters
inFeatures = ["park_boundaries", "rivers"]
outFeatureClass = "c:/output/output.gdb/habitat_areas"
clusTol = "0.05 Meters"
# Use the FeatureToPolygon function to form new areas
arcpy.FeatureToPolygon_management(inFeatures, outFeatureClass, clusTol,
"NO_ATTRIBUTES", "")
