Find service areas

Learn how to calculate the area that can be reached in a given drive 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 Service area 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 and display five, ten, and fifteen minute drive time service areas when the map is clicked.

To learn how to find a route and directions to different locations, visit the Get a route and directions tutorial.

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

To get started, either complete the Display a map tutorial or .

Set the API key

To access ArcGIS services, you need an API key.

Go to your dashboard to get an API key.

In CodePen, set the apiKey to your key, so it can be used to access basemap layer and location services.

Change line
esriConfig.apiKey = "YOUR-API-KEY";
const map = new Map({
  basemap: "arcgis-topographic" //Basemap layer service
});

Add modules

In the require statement, add the ServiceAreaTask, ServiceAreaParameters, FeatureSet, and Graphic modules.

The ArcGIS API for JavaScript uses AMD modules. The require function is used to load modules so they can be used in the main function. It's important to keep the module references and function parameters in the same order.

Add line.

Update the map

A streets basemap layer is typically used in routing applications. Update the basemap property to use the arcgis-navigation basemap layer and change the position of the map to center on Osaka.

Update the basemap property from arcgis-topographic to arcgis-navigation.

Click on the map to see a point graphic.

Create service task parameters

A ServiceAreaTask uses drive times (cutoffs) and spatial reference parameters to calculate the service area. It also uses a FeatureSet to set the facilities (location) from where the service area polygon will be drawn. Use a click handler in the View to set the parameters required to create the service area.

Create a createServiceAreaParams function that takes point graphic, drive time, and spatial reference parameters.

Execute the service area task

To execute the task, pass the serviceAreaParams to the solve method. Use a executeServiceAreaTask function to find the service area polygon and add the resulting graphic to the view.

Create a executeServiceAreaTask function.

Run the app

In CodePen, run your code to display the map.

Click on the map to create service areas. When you click on the map, you will see a point graphic along with drive time service areas. The service areas represent the area that can be reached within 5, 10, and 15 minutes.
