ArcMap

Extract And Clip Data

描述

Extracts features from a source geodatabase that intersects the input area of interest features and adds them into a target geodatabase. The extracted data is then clipped to fall within the input area of interest features. For example, you can use this tool to clip data and add it to smaller databases for distribution.

Example of Extract And Clip Data tool

使用方法

  • The features that are extracted are clipped to the selected area of interest polygon.

  • The newly extracted features can be copied to an empty geodatabase with no schema, and the new geodatabase will have the features and schema added from the extracted features. If the reuse target schema parameter is checked, the features will be copied to the existing target geodatabase schema.

语法

arcpy.defense.ExtractAndClipData(in_aoi_features, in_source_gdb, in_target_gdb, in_reuse_target_schema)
参数说明数据类型
in_aoi_features

A feature layer that describes the processing extent. The feature layer must have one feature selected.

Feature Layer
in_source_gdb

Database that contains the source features to load into the target database.

Workspace
in_target_gdb

The source features will be loaded into this database.

Workspace
in_reuse_target_schema

Specifies if the source schema should be used as the target schema.

  • REUSE —The schema of the source database is not copied into the target database.
  • NO_REUSE —The schema of the source database is copied into the target database. This is the default.
Boolean

代码示例

Extract And Clip Data example (Python window)

The following code sample demonstrates how to execute the tool.

# Importing arcpy
import arcpy

# Checking out extension
arcpy.CheckOutExtension('defense')

# Making AOI feature layer
Index = r'C:\Program Files (x86)\ArcGIS\EsriDefenseMapping\Desktop10.3\ReferenceData\MapIndex.gdb\MapIndex\TLM50_Index'
arcpy.management.MakeFeatureLayer(Index, "TLM50_Index")

# Selecting a single AOI from the AOI feature layer
selection_string = "NRN = 'V795X16573'"
arcpy.management.SelectLayerByAttribute("TLM50_Index", "NEW_SELECTION", selection_string)

# Setting variables to parameters
source_gdb = r'C:\Testing\ExtractTest\MGCP_TRD4.gdb'
target_gdb = r'C:\Testing\ExtractTest\ExtractTest.gdb'

# Calling Extract and Clip Data tool
arcpy.defense.ExtractAndClipData("TLM50_Index", source_gdb, target_gdb, "REUSE")
