Find service areas

A service area, also known as an isochrone, is a polygon that represents the area that can be reached when driving or walking on a street network. The area that can be reached is restricted by either time or distance. To calculate service areas, you can use the routing service. You provide a start location (facilities), one or more time or distance values, and a spatial reference. Once processed, the service returns the service areas that can be reached.

In this tutorial, you create a area that can be reached from a location within a drive time with the route service.

Prerequisites

You need a free ArcGIS developer account to access your dashboard and API keys. The API key must be scoped to access the services used in this tutorial.

Steps

Create a new pen

If you are using the CDN libraries, to get started.

Make the request

Copy and paste the code below, following the steps to make a request to the Routing service.

Reference the ArcGIS REST JS libraries either through CDN, ES Modules, or Node JS.
Set the apiKey with the API key from your dashboard.
Define the parameters needed for the request.
Call the Routing service and handle the results.
