Power Of Phyton Scripting In ArcGIS ( Useful Codes)

Some Useful Phyton Codes For Batch Geoprocessing

Batch Clip Geoprocessing Tool

import arcpy
import os

# The workspace environment needs to be set before ListFeatureClasses
# to identify which workspace the list will be based on

arcpy.env.workspace = "c:/data"
out_workspace = "c:/data/results/"
clip_features = "c:/data/testarea/boundary.shp"

# Loop through a list of feature classes in the workspace

for fc in arcpy.ListFeatureClasses():
    # Set the output name to be the same as the input name, and 
    #    locate in the 'out_workspace' workspace
    output = os.path.join(out_workspace, fc)

    # Clip each input feature class in the list
    arcpy.Clip_analysis(fc, clip_features, output, 0.1)

Batch Save Layer In MXD

# import Phyton Geoprocessing Module
import arcpy

# set up MXD location
mxd = arcpy.mapping.MapDocument("E:\PII_Aceh2014\PII_Aceh2014\PETA INFRASTRUKTUR INDONESIA\ALBUM PETA\A3\Kabupaten\ACEHTAMIANG_2014.mxd")

# Listing Layers in MXD

for lyr in arcpy.mapping.ListLayers(mxd):

# Layer Saving

lyr.saveAcopy( + ".lyr")
