ArcMap

Create Feature Class

Summary

Creates an empty feature class in an enterprise, file geodatabase, or personal geodatabase; in a folder, it creates a shapefile.

Usage

  • The Feature Class Location (geodatabase or folder) must already exist.

  • This tool creates only simple feature classes such as point, multipoint, polygon, and polyline. Custom feature classes such as annotation, dimensions, and relationship are created in the Catalog window or in ArcCatalog by right-clicking a geodatabase and selecting New.

  • A shapefile created by this tool has a field named ID of type integer. The ID field is not created when you provide a Template Feature Class.

Syntax

CreateFeatureclass(out_path, out_name, {geometry_type}, {template}, {has_m}, {has_z}, {spatial_reference}, {config_keyword}, {spatial_grid_1}, {spatial_grid_2}, {spatial_grid_3})
ParameterExplanationData Type
out_path

The enterprise, file, or personal geodatabase, or the folder in which the output feature class will be created. This workspace must already exist.

Workspace; Feature Dataset
out_name

The name of the feature class to be created.

String
geometry_type
(Optional)

The geometry type of the feature class.

  • POINT —
  • MULTIPOINT —
  • POLYGON —
  • POLYLINE —
  • MULTIPATCH
String
template
[template,...]
(Optional)

The feature class used as a template to define the attribute schema of the feature class.

Feature Layer
has_m
(Optional)

Determines if the feature class contains linear measurement values (m-values).

  • DISABLED —The output feature class will not have m-values.
  • ENABLED —The output feature class will have m-values.
  • SAME_AS_TEMPLATE —The output feature class will have m-values only if the template has m-values.
String
has_z
(Optional)

Determines if the feature class contains elevation values (z-values).

  • DISABLED —The output feature class will not have z-values.
  • ENABLED —The output feature class will have z-values.
  • SAME_AS_TEMPLATE —The output feature class will have z-values only if the template has z-values.
String
spatial_reference
(Optional)

The spatial reference of the output feature dataset. You can specify the spatial reference in the following ways:

  • Enter the path to a .prj file, such as C:/workspace/watershed.prj.
  • Reference a feature class or feature dataset whose spatial reference you want to apply, such as C:/workspace/myproject.gdb/landuse/grassland.
  • Define a spatial reference object prior to using this tool, such as sr = arcpy.SpatialReference("C:/data/Africa/Carthage.prj"), which you then use as the spatial reference parameter.

If a spatial reference is not provided, the output will have an undefined spatial reference.

Spatial Reference
config_keyword
(Optional)

The configuration keyword applies to enterprise data only. It determines the storage parameters of the database table.

String
spatial_grid_1
(Optional)

The Spatial Grid 1, 2, and 3 parameters are used to compute a spatial index and only apply to file geodatabases and certain workgroup and enterprise geodatabase feature classes. If you are unfamiliar with setting grid sizes, leave these options as 0,0,0 and ArcGIS will compute optimal sizes for you. Since no features are written by this tool, the spatial index will be in an unbuilt state. The index will be built when features are written to the feature class such as by the Append tool or editing operations. For more information about this parameter, refer to the Add Spatial Index tool documentation.

Double
spatial_grid_2
(Optional)

Cell size of the second spatial grid. Leave the size at 0 if you only want one grid. Otherwise, set the size to at least three times larger than Spatial Grid 1.

Double
spatial_grid_3
(Optional)

Cell size of the third spatial grid. Leave the size at 0 if you only want two grids. Otherwise, set the size to at least three times larger than Spatial Grid 2.

Double

Code sample

CreateFeatureclass example (Python window)

The following Python Window script demonstrates how to use the CreateFeatureclass function in immediate mode.

import arcpy

arcpy.env.workspace = "C:/data"
arcpy.CreateFeatureclass_management("C:/output", "habitatareas.shp", "POLYGON", "study_quads.shp", "DISABLED", "DISABLED", "C:/workspace/landuse.shp")
CreateFeatureclass example 2 (stand-alone script)

The following Python script demonstrates how to use the CreateFeatureclass function in a stand-alone script.

# Name: CreateFeatureclass_Example2.py
# Description: Create a feature class to store the gnatcatcher habitat zones

# Import system modules
import arcpy

# Set workspace
arcpy.env.workspace = "C:/data"

# Set local variables
out_path = "C:/output"
out_name = "habitatareas.shp"
geometry_type = "POLYGON"
template = "study_quads.shp"
has_m = "DISABLED"
has_z = "DISABLED"

# Use Describe to get a SpatialReference object
spatial_reference = arcpy.Describe("C:/workspace/studyarea.shp").spatialReference

# Execute CreateFeatureclass
arcpy.CreateFeatureclass_management(out_path, out_name, geometry_type, template, has_m, has_z, spatial_reference)
