Publish routing services

To publish a routing service, you need to author a GIS resource such as a network analysis layer or a geoprocessing tool in ArcGIS Pro or ArcMap and, publish the resource as a service. A routing service can be published as a map service with the network analysis capability or as a geoprocessing service. The service type you use for routing depends on your objectives and available resources.

Learn more about routing services

The recommended way to publish routing services to your ArcGIS Server site is by using the Publish Routing Services utility included with your ArcGIS Server installation. This utility automates all the steps required to publish the various routing services based on your network dataset.

There can be certain scenarios in which routing services created from the Publish Routing Services utility might not be adequate. In such cases, you can publish routing services to your ArcGIS Server site using ArcGIS Pro or ArcMap. This may be necessary in cases such as the following:

  • You need a routing service to perform additional analysis that is not provided by the routing services created using the Publish Routing Services utility. For example, you may want to use a service that finds the best route between multiple input stops and then uses an elevation dataset (such as a digital elevation model) to generate an elevation profile graph for the route. In such cases, you can publish a geoprocessing service that achieves your desired workflow.
  • You need to use a different network dataset than the one used by services created with the Publish Routing Services utility. For example, your organization may perform a majority of its network analysis based on street centerline data using applications such as ArcGIS Pro or the analysis tools available in the Map Viewer Classic. At the same time, you may also need to perform analysis on an indoor transportation network representing walkways and hallways inside your campus using applications with ArcGIS Indoors. In these cases, you can use the Publish Routing Services utility to publish all the routing services based on the network dataset created from your street centerline data. You can publish additional routing services (as map services with the network analysis capability) based on your indoor network dataset and use these routing services with applications available with ArcGIS Indoors.

Map services for routing

Publishing a routing service as a map service with the network analysis capability involves these steps:

  1. Create a map using ArcGIS Pro or ArcMap.
  2. Add the network dataset to your map.
  3. Create one or more network analysis layers in your map.
  4. Share your map as a map image layer from ArcGIS Pro if your ArcGIS Server site is federated with a portal, or as a map service when publishing to a stand-alone ArcGIS Server site from ArcGIS Pro or ArcMap. Enable the network analysis capability while publishing your map image layer or map service.

Publish a map service with network analysis capability using ArcGIS Pro provides further instructions on how to achieve this workflow using ArcGIS Pro.

Publish a map service with network analysis capability using ArcMap provides further instructions on how to achieve this workflow using ArcMap

Caution:

When publishing a map service or a map image layer, you must enable the network analysis capability to see a routing service in your ArcGIS Server site. Otherwise, your ArcGIS Server site will only have a map service that cannot be used to perform network analysis.

Geoprocessing services for routing

Publishing a geoprocessing service that performs routing involves these steps:

  1. Create a toolbox using ArcGIS Pro.
  2. Author a geoprocessing tool that performs the analysis you need to execute.
  3. Share the geoprocessing tool as a web tool when publishing to a federated ArcGIS Server site, or as a geoprocessing service when publishing to a stand-alone ArcGIS Server site.

The Get Travel Directions geoprocessing service example provides further instructions on how to achieve this workflow using ArcGIS Pro.

The Drive-time Polygons geoprocessing service example provides further instructions on how to achieve this workflow using ArcMap.

Choosing between a map service or a geoprocessing service for routing

While both map services (with the network analysis capability) and geoprocessing services can be used to perform each of the network analyses described above, the type of service you choose to publish a routing service depends on how the applications interact with the routing services. The following table can help you choose a type of routing service.

Objective Type of routing service

Do the applications using the routing service require a very fast response time from the service?

Use a map service with the network analysis capability.

Does the routing service need to support execution of large problems that can take more than a few minutes to solve?

Use a geoprocessing service.

Do you want the maximum number of out-of-the-box applications provided by Esri to work with your routing services?

Use a geoprocessing service.
