Display a scene

Learn how to create and display a scene with a basemap layer and elevation.

A scene contains layers of geographic data that are displayed in 3D. Scenes allow you to display real-world visualizations of landscapes, objects, buildings, and other 3D objects. You display a scene using a scene view to display a basemap layer and data layers, and also to control the center location, tilt, and angle of the view.

In this tutorial, you create and display a scene of the Santa Monica Mountains in California using the topographic basemap layer and the world elevation layer. The scene and code will be used as the starting point for other 3D tutorials.

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

Go to CodePen to create a new pen for your mapping application.

Add HTML

Define an HTML page to create a scene that is the full width and height of the browser window.

In CodePen > HTML, add HTML and CSS to create a page with a viewDiv element for the scene.
The HTML will create a scene that is the full width and height of the page. The viewDiv is the element displays the scene and its CSS resets any browser settings so it can consume the full width and height of the browser.
Note
The <!DOCTYPE html> tag is not required in CodePen. If you are using a different editor or running the page on a local server, be sure to add this tag to the top of your HTML page.
Use dark colors for code blocks

Reference the API

In the <head> tag, add references to the CSS file and JS library.

Add modules

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.

Add a <script> tag and a require statement to load the Map and SceneView modules. You can also add the JavaScript code to the CodePen > JS panel instead of the HTML panel. If you do so, remove the <script> tag.

Get an API key

An API key is required to access ArcGIS services.

Go to your developer dashboard to get an API key.
Copy the key as it will be used in the next step.

Create a scene

Use a Map to define the basemap layer and elevation surface. Scenes use the information in the elevation layer to determine the ground (surface) height that will be rendered on the map.

Go back to CodePen.

At the beginning of the main function, set your API key.

  <script>
    require([
      "esri/config",
      "esri/Map",
      "esri/views/SceneView"
  ], function(esriConfig, Map, SceneView) {

    esriConfig.apiKey = "YOUR_API_KEY";

Create a Map and set the basemap property to arcgis-topographic and the ground property to world-elevation.

    const map = new Map({

      ground: "world-elevation", //Elevation service
    });
Expand

Create a scene view

Use a SceneView class to set the map and layers to draw, as well as to define the camera position. The camera is the point from which the visible extent of the SceneView is determined. The tilt property refers to the number of degrees from the surface that the camera is pointed.

Create a SceneView. Set the container, map, and camera properties.

      ground: "world-elevation", //Elevation service
    });

    const view = new SceneView({
      container: "viewDiv",
      map: map,
      camera: {
        position: {
          x: -118.808, //Longitude
          y: 33.961, //Latitude
          z: 2000 //Meters
        },
        tilt: 75
      }
      });

Run the app

In CodePen, run your code to display the map.

The scene view should display the topographic basemap layer and elevation layer for an area of the Santa Monica Mountains in California.
