Tutorial: Add map tiles

Learn how to add map tiles from a map tile serviceA map tile service, formerly known as image tile service, is a data service that provides access to static, pre-rendered mao tiles. The tiles are typical in PNG format. Map tiles are typically retrieved by specifying a specific level, row, and column value.Learn more to a sceneA scene is a collection of layers that are displayed in 3D. It is typically composed of a basemap layer, data layers, and 3D data.Learn more.

Map tiles are a type of tileA tile is an image, often a graphics file (such as a .jpg), typically stored in a directory known as a cache. The image is part of a set of tiles that, conceptually, are pieces of a bigger map.Learn more data that are stored in an map tile serviceA map tile service, formerly known as image tile service, is a data service that provides access to static, pre-rendered mao tiles. The tiles are typical in PNG format. Map tiles are typically retrieved by specifying a specific level, row, and column value.Learn more. 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 serviceA feature service is a data service that provides access to spatial and non-spatial data in feature layers, feature layer views, and tables.Learn more in your portalArcGIS portal, also known as a portal, is a website with applications and tools that can be used to create, manage, access, and share geospatial content and data. It supports security and authentication, developer credentials, content and data service management, user and group management, and site administration. A portal can be hosted in Esri's infrastructure or your own infrastructure.Learn more.

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

Prerequisites

Steps

Get the starter app

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

Set up authentication

Set developer credentials

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.

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

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