Find service areas

Learn how to calculate the area that can be reached in a given drive time from a location A location is a position or region (point, line, or polygon) on the earth's surface. Learn more .

A service area A service area is a polygon representing the distance that can be reached within a specified length of time while traveling in a street network. Learn more , also known as an isochrone, is a polygon A polygon is a type of geometry containing an array of rings and a spatial reference. Each ring contains an array of point coordinates, where the first and last point are the same. Learn more that represents the area that can be reached when driving or walking on a street network A network is a set of features that are typically interconnected to each other within a region. Learn more . The area that can be reached is restricted by either time or distance. To calculate service areas, you can use the Service area service A routing service is a service that uses network analysis and streets data to calculate the most effective path and turn-by-turn directions on a street network, optimize fleet routing and deliveries, find the closest facilities, calculate service areas, and more. It is hosted by Esri as the ArcGIS Routing service and can also be hosted in ArcGIS Enterprise. Learn more . You provide a start location A location is a position or region (point, line, or polygon) on the earth's surface. Learn more (facilities), one or more time or distance values, and a spatial reference A spatial reference is a set of parameters, typically defined by a WKID, that define the coordinate system and spatial properties for geographic data. Applications use a spatial reference to correctly display the position of geographic data in a map or scene. Learn more . Once processed, the service returns the service areas that can be reached.

In this tutorial, you will create and display five, ten, and fifteen minute drive time service areas when the map is clicked.

Prerequisites

Steps

Create a new pen

1. To get started, either complete the Display a map tutorial or use this pen .

Get an access token

You need an access token An access token is an authorization string that provides access to secure ArcGIS content, data, and services. Its capabilities are determined by the privileges it supports. It is obtained by implementing API key authentication, User authentication, or App authentication. Learn more with the correct privileges to access the location services ArcGIS Location Services, also referred to as Location Services, are services hosted by Esri that provide geospatial functionality for developing mapping applications. They include the ArcGIS Basemap Styles service, ArcGIS Static Basemap Tiles service, ArcGIS Places service, ArcGIS Geocoding service, ArcGIS Routing service, ArcGIS GeoEnrichment service, and ArcGIS Elevation service. An ArcGIS Location Platform or ArcGIS Online account is required to use the services. Learn more used in this tutorial.

1. Go to the Create an API key tutorial and create an API key An API key is a long-lived access token created using API key credentials. They are valid for up to one year and are typically embedded directly into client applications. Learn more with the following privilege(s) Privileges are a set of permissions assigned to ArcGIS accounts, developer credentials, and applications that grant access to secure resources and functionality in ArcGIS. Learn more :
   
   • Privileges
     • Location services > Basemaps
     • Location services > Routing
2. In CodePen, set the apiKey property on the global esriConfig variable to your access token.

     var esriConfig = {
       apiKey: "YOUR_ACCESS_TOKEN",
     };

To learn about other ways to get an access token, go to Types of authentication.

Update the map

A streets basemap layer A basemap layer is the layer in a map or scene that displays basemap data. The data source for a basemap layer is typically a basemap service. Learn more is typically used in routing applications. Update the basemap attribute to use the arcgis/navigation basemap layer and change the position of the map to center on Osaka.

1. Update the basemap attribute from arcgis/topographic to arcgis/navigation. Then change the zoom and center attributes to center on Osaka.

Add modules and wait for the Map to be ready

1. Add a <script> tag in the <body> following the <arcgis-map> component. Use $arcgis.import() to add the serviceArea, ServiceAreaParameters, FeatureSet, and Graphic modules.

   More info

   The ArcGIS Maps SDK for JavaScript ArcGIS Maps SDK for JavaScript, previously known as ArcGIS API for JavaScript, is a developer product for building mapping and spatial analysis applications for the web. Learn more is available via CDN and npm, but this tutorial is based on CDN. The $arcgis.import global function accepts a module path or array of module paths, and returns a promise that resolves with the requested modules. This function can only be used when working with the CDN; otherwise, use the standard import syntax. To learn more about the SDK’s different modules, visit the References page.

   Use the document.querySelector() method to access the map component.

Solve the service area

To solve the service area, pass the serviceAreaParams to the solve method. Use a solveServiceArea function to find the service area polygon A polygon is a type of geometry containing an array of rings and a spatial reference. Each ring contains an array of point coordinates, where the first and last point are the same. Learn more and add the resulting graphic to the map.

1. Create a solveServiceArea 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 A graphic is a visual element composed of a geometry, symbol, and attributes that is displayed on a map or scene. Learn more along with drive time service areas. The service areas represent the area that can be reached within 5, 10, and 15 minutes.
