How can we split a polyline into multiple segments (say each with 10% of the total length) using Python scripts?

You can split it into two tasks based on Python interfaces available.

1)The below snippet creates a points at a specified interval based on an input line feature layer.

import arcpy

line_lyr = 'my_line'

pt_lyr = "my_point"

interval = 200

insertCursor = arcpy.da.InsertCursor(pt_lyr, ["SHAPE@XY"]) # this is the pre-existing pt feature class

with arcpy.da.SearchCursor(line_lyr, ['OID@','SHAPE@','NAME']) as searchCursor: # this is the line feature on which the points will be based

for row in searchCursor:

lengthLine = round(row[1].length) # grab the length of the line feature, i'm using round() here to avoid weird rounding errors that prevent the numberOfPositions from being determined

if int(lengthLine % interval) == 0:

numberOfPositions = int(lengthLine // interval) - 1

else:

numberOfPositions = int(lengthLine // interval)

print "lengthLine", lengthLine

print "numberOfPositions", numberOfPositions

if numberOfPositions > 0: # > 0 b/c we don't want to add a point to a line feature that is less than our interval

for i in range(numberOfPositions): # using range, allows us to not have to worry about

distance = (i + 1) * interval

xPoint = row[1].positionAlongLine(distance).firstPoint.X

yPoint = row[1].positionAlongLine(distance).firstPoint.Y

xy = (xPoint, yPoint)

insertCursor.insertRow([xy])

2)Use above result point feature class you can split the line feature class

#Name: SplitLineAtPoint_Example.py

# Description: split line features based upon near point features; Search Distance is in linear

# unit meters

# Requirements:

# Author: ESRI

import arcpy

from arcpy import env

env.workspace="C:/data"

inFeatures="my_line"

pointFeatures="my_point"

outFeatureclass="splitline_out.shp"

searchRadius= "20 Meters"

try:

arcpy.SplitLineAtPoint_management(inFeatures, pointFeatures, outFeatureclass, searchRadius)

except Exception, e:

# If an error occurred, print line number and error message

import traceback, sys

tb = sys.exc_info()[2]

print "Line %i" % tb.tb_lineno

print e.message
