Find service areas
Learn how to calculate the area that can be reached in a given driving time from a location.
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 use ArcGIS REST JS to access the routing service to create and display five, ten, and fifteen minute drive time service areas when the map is clicked. You use data-driven styling to give each polygon a different shade of blue.
Prerequisites
You need an ArcGIS account to access the developer dashboard and create an API key.
Steps
Create a new pen
- To get started, either complete the Display a map tutorial or .
Set the API key
To access location services, you need an API key or OAuth 2.0 access token. To learn how to create and scope your key, visit the Create an API key tutorial.
Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial.

Add service area layer
To show the service area, you will use a fill layer to display a GeoJSON source. Each polygon has a property called FromBreak which contains the lower bound of the number of minutes of travel: 0, 5 and 10 minutes. You can use an expression for the fill-color to display each polygon in a different shade of blue.

Add a load event handler
You need to use the load event to ensure the map is fully loaded, before adding your layers.
Add an event handler to the map
loadevent. Call theaddServiceAreaLayer()andaddStartingPointLayer()functions here.The order in which layers are added to the map is the order in which they will be displayed: layers added later are displayed over the top. Therefore, to have the starting point layer remain visible, you should add it after the service area layer.

When you click on the map, the white circle should move to each location that you click.
Get the service area
With the coordinates of the click event, you can now call the serviceArea function in the route service to get the service area.
Inside the click handler, create a new
arcgisRest.ApiKeyManagerto access the route service. Call theserviceAreamethod. Set thefacilitiesparameter with the clicked coordinates to calculate the service area.The
facilitiesparameter lets you pass in multiple locations around which the service area is calculated. In this case, you are only passing one.By default, the three drive times that are requested are 5, 10 and 15 minutes. You can change these by passing the
defaultBreaksparameter.Use dark colors for code blocks Add line. Add line. Add line. Add line. Add line. Add line.
