Hoe kan ik mijlpalen maken voor wegen en paden met ArcGIS 10.2?

Question

<\/HEAD>We moeten in staat zijn om mijlpaalpunten te maken van onze shapefiles voor weglijnen en padlijnen. Ik heb Advanced ArcGIS Desktop 10.2 en onze transportmedewerkers hebben Basic 10.2. Is er een python-script of een geoprocessing-tool beschikbaar om dit te doen? <\/P><\/BODY><\/HTML>

I do it like this because I use LRS. With this script I can use my routes with measures to create points at different increments for different LRS Reference Methods: pydot/HatchFake.py at master · KDOTGIS/pydot · GitHub ''' Created on Jul 14, 2015 This script will create route events as points along the route features at specific increments the points can be symbolically displayed as route hatches for web mapping @author: Kyle Gonterwitz with, as always the amazing help from Dirk Talley @contact: Kyleg@Ksdot.org ''' #import arcpy from arcpy import (AddField_management, MakeFeatureLayer_management, CreateTable_management,da, Exists, AddXY_management, TruncateTable_management, Append_management, MakeRouteEventLayer_lr, Delete_management, FeatureClassToFeatureClass_conversion, env) #set the geodatabase parameters for the input route data env.overwriteOutput = True wsPath = r"Database Connections\shared@SQLGIS_cansys_gis_dev.sde" #enter the workspace path that has the data owner login StatefcRoutes = r"\gisdata\arcgis\GISdata\Connection_files\RO@sqlgisprod_GIS_cansys.sde\GIS_CANSYS.SHARED.SMLRS" # State Route feature class with begin/end attribs CountyfcRoutes = r"\gisdata\arcgis\GISdata\Connection_files\RO@sqlgisprod_GIS_cansys.sde\GIS_CANSYS.SHARED.CMLRS" #County Route Feature Class with begin/end attribs #State and County are the Two main Linear Referecing Methods used by KDOT which will be hatched StateOutTable = "SMHatch" CountyOutTable= "CMHatch" StateFields = ["LRS_Route", "BEG_STATE_LOGMILE", "END_STATE_LOGMILE"] CountyFields = ["LRS_KEY", "BEG_CNTY_LOGMILE", "END_CNTY_LOGMILE"] #this field sets the hatch separation/spacing.
