ArcGIS Pipeline Referencing/Esri Roads and Highways: Preparing and Utilizing Web Services for Creating and Editing Linear Referenced Data and with the REST API

Location Referencing across the ArcGIS Platform

• Location Referencing extension is part of the Pro install• Linear referencing capability for server is part of the ArcGIS Enterprise install

Pro

• Network and CenterlineManagement

• Route and Event Loading• Geoprocessing tools• Data Reviewer and Workflow

Manager included

Enterprise

• LRS web services• Developer API samples

Web Apps

• Line and point event editing• Data queries• Quality checks

Linear Referencing REST APIProvides a simple, open web interface to linear referencing services hosted by ArcGIS Enterprise.

Supports Esri’s Feature Services Architecture – feature service editing across the ArcGIS Platform including ArcGIS Pro and web apps

Demo: Publishing a service with LR capability

Login as a Publisher/Administrator

into ArcGIS Pro

Convert an empty Enterprise GDB to a Branched Database

Create LRS, Network and Events in the

Branched Database

Append data into the Network and Events

Add the Network, Events, Calibration Point, Centerline

feature classes into a Pro Map for Publishing

Set up the Display Field for the Centerline

Update the Layer names in the TOC

Set up time for the LRS layers Save the map

Publish the Map

Fix any publishing issues

Create a new Map in the ArcGIS Pro Project

for Editing

Browse to the Feature Service in the Portal in

ArcCatalog and add the LRS layers into the

map

Create a new version of the data

Start Editing the LRS dataset

Step by step workflow for publishing a LR capable service

Step1: Minimum Requirements

ArcGIS Pro with Location Referencing extension enabledArcGIS Enterprise with Location Referencing License

• Login to ArcGIS Pro as a portal Publisher or Administrator

Helpful steps in ArcGIS Pro

Step2: Configure a branch versioned database

• Right-click your database connection and choose Geodatabase connection properties

• Set your Versioning Type to Branch

Branched database can be edited only using REST services

Step3: Create LRS and append data

Step4: Rename Layers

Step5: Set up time awareness

Step6: Set up the display field for the centerline

Step7: Publish the service with Linear Referencing Capability

Step8: Add the Data from Portal to edit

Step9: Create a new version for the data

Quick Recap

• ArcGIS Pro publishes, consumes, and then edits LRS feature services from ArcGIS Enterprise.

• Portal handles identity, sharing (of the feature service), and roles/privileges/access that would previously have been file based (.sde connection files) or administered directly in the database.

• Versioned editing is handled via the version management service, allowing Pro and web apps to have versioning capabilities through the rest endpoint without direct database access at the desktop client level.

• Branch versioned database is required for editing a LR feature service.

• You can start to configure your LRS from scratch here:https://pro.arcgis.com/en/pro-app/help/production/location-referencing-pipelines/create-the-lrs-networks-and-events.htm
