ArcGIS Roads and Highways

ArcGIS Roads and Highways is an ArcGIS Server extension that provides the capability to publish your LRS Networks and registered event layers as a map service.

As a map service, your linear referenced data can be shared to an ArcGIS Enterprise deployment and published to your organizational account at ArcGIS Online.

Networks and events can be consumed by any client app that can consume an ArcGIS Server map service, including existing ArcGIS Desktop web and mobile clients. In addition, web developers can use the ArcGIS Server Web APIs to develop web and connected mobile apps against your linear referenced data.

Enabling Roads and Highways

The stand-alone Location Referencing installer is no longer required in 10.9 or later releases. However, the software must be authorized using your Location Referencing license key on each machine.

A full base ArcGIS Enterprise deployment is required and must be installed to compatible versions.

Authorizing the software

Visit My Esri to obtain authorization (by email, fax, phone, or mail), then use your license key to authorize the following:

Once the ArcGIS Location Referencing license is used to authorize each instance of ArcGIS Server, the Roads and Highways features and services that are native to ArcGIS Enterprise are available to use.

Compatibility with ArcGIS Pro

ArcGIS Pro and ArcGIS Enterprise must be installed to compatible versions:

Remarque :

This applies only to services published using ArcGIS Pro.

Add the Linear Referencing capability to map services

Roads and Highways extends an existing ArcGIS Server map service with an additional REST service capability for linear referencing. These additional REST services support the following linear referencing tasks:

  • Provide LRS-based network and event layer information
  • Translate coordinate locations to routes and measures
  • Translate (Locate) routes and measures to coordinates or polylines
  • Validate route and measure values
  • Convert measures from one LRM to another
  • Multilayer, transactional event editing, with support for overlap retirement and coincident event merging

Learn more about the Linear Referencing Service REST API and enabling the Linear Referencing capability.

Roads and Highways JavaScript web developer samples

To demonstrate the pattern of use of the REST services exposed by Roads and Highways, the server product comes packaged with JavaScript developer samples.

Roads and Highways sample web apps

These developer samples demonstrate how a web or connected mobile developer would do the following:

  • Visualize networks on a map
  • Visualize events on a map
  • Locate measures on a route
  • Perform spatial and attribute queries for routes
  • Perform spatial, measure, and attribute queries for events
  • Convert routes and measures to coordinates
  • Convert coordinates to routes and measures
  • Convert measures between linear referencing methods (LRMs)

Roads and Highways provides online hosted versions of these developer samples.
