Display a web scene

A web scene is a scene that is stored as an item in ArcGIS Online. A web scene item contains all of the configuration settings for the scene (in JSON format) such as extent, basemap, data layers, and styles. Applications can access and display the web scene using its item ID.

In this tutorial, you access and display a pre-configured web scene stored in ArcGIS Online.

Prerequisites

Steps

Create a new pen

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

Set the API key

To access ArcGIS services, you need an API key.

1. Go to your dashboard to get an API key.

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

   Use dark colors for code blocks

   esriConfig.apiKey = "YOUR_API_KEY";
   const map = new Map({
     basemap: "arcgis-topographic" // Basemap layer service
   });

Add modules

1. In the require statement, delete the Map and MapView modules. Add the WebScene, SceneView, and Legend modules.

   More info

   The ArcGIS Maps SDK for JavaScript is available as AMD modules and ES modules, but this tutorial is based on AMD. The AMD require function uses references to determine which modules will be loaded – for example, you can specify "esri/Map" for loading the Map module. After the modules are loaded, they are passed as parameters (e.g. Map) to the callback function where they can be used in your application. It is important to keep the module references and callback parameters in the same order. For more information on the different types of modules, visit the Introduction to Tooling guide topic.

Load the web scene

You can use the portal item ID to create a WebScene. The web scene will be passed to the view.

1. Delete the code that creates the Map and the MapView.
