Geodatabase To Shape (Topographic Production)

Summary

Exports one or more feature classes in a geodatabase to shapefiles using one of three modes: defense, generic, and Multinational Geospatial Co-Production Program (MGCP).

Each mode controls how the output shapefiles are named. The defense and MGCP export modes follow Defense Mapping data model requirements. The generic mode uses the same logic as the Feature Class To Feature Class tool.

Usage

• The Conversion Method parameter specifies the export mode.

• Coded domain values are exported as part of the shapefile to maintain data integrity. You can choose to export them as raw values, string descriptions, or both.

Parameters

Dialog

Label	Explanation	Data Type
Input Features	The features used to create the shapefiles.	Feature Layer
Output Folder	The folder that will contain the output shapefiles.	Folder
Coded Value Domain Export Mode	Indicates what method will be used to export coded domain values. Descriptions—Coded domain values will be exported using their descriptions rather than raw values. Values—Coded domain values will be exported as raw values. This is the default. Values and descriptions—Coded domain values will be exported as raw values and string descriptions	String
Conversion Method	Indicates which conversion method will be applied. Defense by feature class—Creates a shapefile based on the feature class name and removes trailing underscores from fields. Defense by subtype—Creates a shapefile based on subtype name, exports attributes applicable to that subtype, and removes trailing underscores from fields. This is the default. Generic by feature class—Creates a shapefile for each feature class selected. The shapefile name matches the feature class name. Generic by subtype—Creates a shapefile for each subtype of the feature class selected. The shapefile name matches the subtype name. MGCP—Creates a shapefile based on the feature class subtype. The shapefile is named using the geometry type and feature code. For example, the River subtype in the WatrcrsL feature class would be exported to a shapefile called LBH140.	String
Create Empty Shapefiles	Indicates that the tool will create empty shapefiles if the input feature classes are also empty. Checked—Create empty shapefiles if the corresponding feature classes to export are empty. Unchecked—Do not create empty shapefiles if the corresponding feature classes to export are empty. This is the default.	Boolean

Derived Output

Label	Explanation	Data Type
Derived Folder	Folder containing output shape files created from input_features.	Folder

Python

arcpy.topographic.GeodatabaseToShape(in_features, output_folder, coded_value_domain_export_mode, conversion_method, create_empties)

Name	Explanation	Data Type
in_features [in_features,...]	The features used to create the shapefiles.	Feature Layer
output_folder	The folder that will contain the output shapefiles.	Folder
coded_value_domain_export_mode	Indicates what method will be used to export coded domain values. DESCRIPTIONS—Coded domain values will be exported using their descriptions rather than raw values. VALUES—Coded domain values will be exported as raw values. This is the default. VALUES_AND_DESCRIPTIONS—Coded domain values will be exported as raw values and string descriptions	String
conversion_method	Indicates which conversion method will be applied. DEFENSE_BY_FEATURECLASS—Creates a shapefile based on the feature class name and removes trailing underscores from fields. DEFENSE_BY_SUBTYPE—Creates a shapefile based on subtype name, exports attributes applicable to that subtype, and removes trailing underscores from fields. This is the default. GENERIC_BY_FEATURECLASS—Creates a shapefile for each feature class selected. The shapefile name matches the feature class name. GENERIC_BY_SUBTYPE—Creates a shapefile for each subtype of the feature class selected. The shapefile name matches the subtype name. MGCP—Creates a shapefile based on the feature class subtype. The shapefile is named using the geometry type and feature code. For example, the River subtype in the WatrcrsL feature class would be exported to a shapefile called LBH140.	String
create_empties	Indicates that the tool will create empty shapefiles if the input feature classes are also empty. CREATE_EMPTIES—Create empty shapefiles if the corresponding input feature classes are empty. NO_CREATE_EMPTIES—Do not create empty shapefiles if the corresponding input feature classes are empty. This is the default.	Boolean

Derived Output

Name	Explanation	Data Type
derived_folder	Folder containing output shape files created from input_features.	Folder

Code sample

GeodatabaseToShape example (stand-alone script)

The following stand-alone script demonstrates how to use the GeodatabaseToShape tool to export feature classes from an MGCP workspace to shapefiles.

# Name: GeodatabaseToShape_sample.py
# Description: Exports feature classes from an MGCP workspace to shapefiles

# Import System Modules
import arcpy

# Check Out Extensions
arcpy.CheckOutExtension('Foundation')

# Setting Local Variables
in_features = r'C:\Temp\Test.gdb\MGCP\AerofacA;C:\Temp\Test.gdb\MGCP\AerofacP;C:\Temp\Test.gdb\MGCP\AgristrA;C:\Temp\Test.gdb\MGCP\AgristrP'
in_shape_folder = r'C:\Temp\Shapefiles'
in_output_type = 'Values'
in_conversion_method = 'MGCP'

# Execute Geodatabase To Shape Function
arcpy.topographic.GeodatabaseToShape(in_features, in_shape_folder, in_output_type, in_conversion_method)

# Check In Extensions
arcpy.CheckInExtension('Foundation')
