Tutorial: Add map tiles | CesiumJS

Learn how to add map tiles from a map tile service to a scene.

Add a map tile layer using API key authentication Add a map tile layer using user authentication

Map tiles are a type of tile data that are stored in an map tile service. They typically display raster imagery, such as aerial photography, but can also be used to display other data. You can create an map tile service by publishing a feature service in your portal.

In this tutorial, you use CesiumJS to display the Kilauea Volcano Shortwave Infrared map tile layer.

Portal and data services guide

To learn how to publish your own map tile service, go to Introduction to map tile services.

Prerequisites

An ArcGIS Location Platform or ArcGIS Online account.

Steps Get the starter app

Select a type of authentication below and follow the steps to create a new application.

You can choose one of the following to create a new CodePen:

Option 1: Complete the Display a scene tutorial; or,
Option 2: Start from the Display a scene tutorial .

Go to the Display a scene tutorial and download the solution.
Unzip the folder and open it in a text editor of your choice, such as Visual Studio Code. The starter app includes the following:
- callback.html: This contains callback as part of the authentication process.
- index.html: This contains app logic and the OAuth 2.0 code necessary to perform the authentication.

Set up authentication

Create developer credentials in your portal for the type of authentication you selected.

Create a new API key credential with the correct privileges to access the resources used in this tutorial.

Go to the Create an API key tutorial and create an API key with the following privilege(s):
- Privileges
  - Location services > Basemaps
- Item access
  - Note: If you are using your own custom data layer for this tutorial, you need to grant the API key credentials access to the layer item. Learn more in Item access privileges.
Copy the API key access token to your clipboard when prompted.

Create a new OAuth credential to register the application.

Go to the Create OAuth credentials for user authentication tutorial to create an OAuth credential.
Copy the Client ID and Redirect URL from your OAuth credentials item and paste them to a safe location. They will be used in a later step.

Note

To use this application, users must have an ArcGIS account with the necessary privileges to access all resources and services.

Set developer credentials

Use the API key or OAuth developer credentials created in the previous step in your application.

Add <script> elements in the HTML <body> and create an accessToken variable to store your access token. Set YOUR_ACCESS_TOKEN with the access token you previously copied from your API key credentials.

      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    })

Run the app and ensure you can sign in successfully.

If you are unable to sign in, make sure you have the correct redirect URL and port. This URL varies based on your application and typically takes the format of https://<server>[:port]/callback.html or http://my-arcgis-app:/auth. For example, if you are running an application on http://127.0.0.1:5500/, set http://127.0.0.1:5500/callback.html as your redirect URL in the index.html and callback.html file and your developer credential. They all have to match!

Get a Cesium ion access token

All Cesium applications must use an access token provided through Cesium ion. This token allows you to access assets such as Cesium World Terrain in your application.

Go to your Cesium ion dashboard to generate an access token. Copy the key to your clipboard.

Create a cesiumAccessToken variable and replace YOUR_CESIUM_ACCESS_TOKEN with the access token you copied from the Cesium ion dashboard.
