Create Cross-Reference Geodatabase (Topographic Production)

摘要

Creates a cross-reference geodatabase that the Load Data tool uses to map source data to target data when loading batch data.

使用情况

• The Output Database parameter value can be used as the input cross-reference geodatabase in the Load Data tool.

• The Source Workspace parameter value can be a geodatabase or shapefile.

• The Target Database parameter value must be a geodatabase.

• This tool will create a file geodatabase containing the tables and records required for transforming and loading the Source Workspace parameter value into the Target Database parameter value.

• When the schema of the Source Workspace and Target Database parameter values don't match, the mapping file can be used to define how the features are mapped.

• The Mapping File Excel spreadsheet requires a specific format. The template is included in the Production Mapping product files for use when defining a custom mapping file.

• If no Mapping File parameter value is specified, the cross-reference geodatabase will contain mappings between all feature classes and fields that have the same name.

• This tool will provide warnings when mappings cannot be created in the cross-reference geodatabase for the following scenarios:

  • An object class (feature class, shapefile, or table) in the source cannot be mapped to an object class in the target.
  • A field in a source object class cannot be mapped to a field in the target object class.
  • An object class in the target doesn't have a source object class mapped to it.
  • A field in a target object class exists but there is no field in the source object class mapped to it.
  • An object class is listed in the Mapping File parameter value that doesn't exist in the Source Workspace or Target Database parameter values.
  • A field is listed in the Mapping File parameter value that doesn't exist in the source or target object class.
  • The field type of a source field doesn't match the field type of a target field and no value mapping is provided.

代码示例

CreateCrossReferenceGeodatabase example (stand-alone script)

The following code sample demonstrates how to use the Create Cross-Reference Geodatabase function.

# Name: CreateCrossReferenceGeodatabase_sample.py
# Description: Creates cross-reference geodatabases that the Load Data tool uses
# to map source data to target data.

# Import System Modules
import arcpy

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

# Setting Local Variables
source_workspace = r'C:\Data\Source_Shapefiles'
target_database = r'C:\Data\Target_MGCP_TRD_4_6.gdb'
out_database = r'C:\Data\MGCP_TRD_4_5_1_SHP_to_MGCP_TRD_4_6_GDB.gdb'
mapping_file = r'C:\Data\MGCP_TRD_4_5_1_SHP_to_MGCP_TRD_4_6_GDB.xls'

# Use the Create Cross-Reference Geodatabase GP tool to load source shapefiles to MGCP_TRD_4_6.gdb
arcpy.topographic.CreateCrossReferenceGeodatabase(source_workspace, target_database, out_database, mapping_file)

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