代码实例

增加最大边数 (IncreaseMaximumEdges) 示例 1(Python 窗口)

使用所有参数执行此工具。

import arcpy
arcpy.env.workspace = "C:/ArcTutor/Network Analyst/Tutorial/SanFrancisco.gdb"
arcpy.na.IncreaseMaximumEdges("Transportation/RestrictedTurns",8)
增加最大边数 (IncreaseMaximumEdges) 示例 2(独立 Python 脚本)

以下 Python 脚本演示了如何在独立脚本中使用增加最大边数 (IncreaseMaximumEdges) 工具。

# Name: IncreaseMaximumEdges_ex02.py
# Description: Increase maximum edges for turn features from 2 to 5.
# Requirements: Network Analyst Extension 

#Import system modules
import arcpy
from arcpy import env


#Check out the Network Analyst extension license
arcpy.CheckOutExtension("Network")

#Set environment settings
env.workspace = "C:/data/SanFrancisco.gdb/Transportation"

#Set local variables
inTurnFeatures = "RestrictedTurns"
maxEdges = 8

#Increase the edges for turn features
arcpy.na.IncreaseMaximumEdges(inTurnFeatures, maxEdges)

print "Script completed successfully."
