Load Data (Topographic Production)

サマリー

Moves features from one schema to another by loading data from a source to a target workspace. Data mapping rules described in a cross-reference database are applied during loading.

Data that matches the schema defined in the cross-reference database for the source is appended to the target workspace. The cross-reference database contains a DatasetMapping table that lists pairs of source and target dataset names. Each source and target name pair can have a WHERE clause and a subtype. The WHERE clause defines a subset of features in the source to append to the target. Subtype identifies a subtype in the target feature class into which features are loaded.

注意:

A product file installer is available for ArcGIS Production Mapping and ArcGIS Defense Mapping. The product files contain predefined cross-reference geodatabases that can be used for loading data.

使用法

• The cross-reference database includes other tables that affect load data functionality. These tables enable the following operations:

  • Map fields between data sources.
  • Override values from source to target.
  • Specify different source and target schema owners for enterprise geodatabases.

• Use the Dataset Mapping Definitions parameter to specify which feature classes, shapefiles, or coverages to load from the input source to the target workspace. The list of sources and targets comes from the DatasetMapping table in the cross-reference database.

• You can only set WHERE clauses and subtypes in the DatasetMapping table in the cross-reference database. You cannot set these in the Dataset Mapping Definitions parameter.

• The ID value used in the Dataset Mapping Definitions parameter must refer to an existing row ID in the DatasetMapping table in the cross-reference database. The row in the DatasetMapping table contains the name of the source and target datasets.

• This tool returns the warning Source dataset [dataset name] not found or is inaccessible for each source feature class listed in the cross-reference database that is not found in the input sources workspace.

• This tool returns the warning Target dataset [dataset name] not found or is inaccessible for each target feature class listed in the cross-reference database that is not found in the target workspace.

LoadData example (stand-alone script)

The following script demonstrates how to use the LoadData function to load data from one geodatabase to another using a cross-reference geodatabase.

# Name: LoadData_sample.py
# Description: Loading data from one geodatabase to another using a cross-reference geodatabase

# Import System Modules
import arcpy

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

# Setting Local Variables
cross_reference = r'C:\Temp\Cross_Reference.mdb'
source_database = r'C:\Temp\Source.gdb'
target_database = r'C:\Temp\Target.gdb'

# Loading data from the source to the target geodatabase
arcpy.topographic.LoadData(cross_reference, source_database, target_database)

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