Arcpy按属性(字段值)不同将shp分割为多个独立shp_适用点线面矢量

利用代码可以进行批量处理，安装有10.5及以上版本ArcGIS可以使用工具Split by attributes完成上述任务

# -*- coding: utf-8 -*-

# Import system modules

import re

import arcpy

from arcpy import env

# function for replace special characters

def validateTitle(title):

    rstr = r"[\/\\\:\*\?\"\<\>\|\,\.\ ]"  # '/ \ : * ? " < > | , . '

    new_title = re.sub(rstr, "_", title)  # replace rstr by '_'

    return new_title

# Set workspace

env.workspace = "C:/Users/pan/Desktop/test" # your workspace

# Set local variables

in_features = "C:/Users/pan/Desktop/test/rivers.shp" # replace by your filepath to split

# Open a searchcursor

rows = arcpy.SearchCursor(in_features, fields="NAME") # replace "NAME" by your target field name

# Iterate through the rows in the cursor, select the river by name and export,

for row in rows:

    selected_field_value = row.getValue("NAME")

    where_clause = '"NAME" = \'%s\''%(str(selected_field_value))

    outfilename = validateTitle(str(selected_field_value))

    out_feature_class = "C:/Users/pan/Desktop/test/out/%s.shp"%(outfilename)

    # Execute Select

    arcpy.Select_analysis(in_features, out_feature_class, where_clause)

    print(str(selected_field_value)+' has done!!!')

如果对代码中调用的Arcpy功能API不了解，可以移步ArcGIS帮助
