Display a custom basemap style

Learn how to access and display a styled vector basemap layer in a map.

A styled basemap layer is a set of styles that you define to override one of the default basemap styles service vector tile layer styles. These are used to create and display a map or scene with your own custom styles, labels, and colors. To create a styled basemap layer, you can use the ArcGIS Vector Tile Style Editor. The editor stores your styles in ArcGIS as a layer item with an item ID.

In this tutorial, you will use an item ID to access and display a styled vector tile layer (Forest and Parks Canvas) in a map. You also add an image tile layer (World Hillshade) to enhance the visualization. Both layers are hosted in ArcGIS Online.

Prerequisites

You need an ArcGIS Developer or ArcGIS Online account to access the dashboard and create an API key.

Steps

Create a new pen

To get started, either complete the Display a map tutorial or .

Set the API key

To access ArcGIS services, you need an API key.

Go to your dashboard to get an API key.
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 styles service
});

Add modules

In the require statement, add the Basemap, VectorTileLayer, and TileLayer 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.

Create a vector tile layer

You can access a basemap layer by referencing its item ID. You can find a layer's item ID by accessing it with ArcGIS Online or the ArcGIS Vector Tile Style Editor.

Go to the Forest and Parks Canvas vector tile layer in ArcGIS Online and find its item ID. The ID is at the end of the URL.
In CodePen, create a new VectorTileLayer object and set its portalItem id property to d2ff12395aeb45998c1b154e25d680e5 and the opacity property to 0.75.

        },
        opacity: 0.75
      });

Create an image tile layer

Use ArcGIS Online to find the item ID for the World Hillshade image tile layer and then use it to access the layer. The image tile layer will be used to visually enhance the styles with terrain.

Go to the World Hillshade image tile layer in ArcGIS and find its item ID. The ID is at the end of the URL.
In CodePen, create a new TileLayer and set its portalItem id property to 1b243539f4514b6ba35e7d995890db1d.

Add the basemap layers

Basemaps can contain multiple baselayers. Use the Basemap class to add the vectorTileLayerand imageTileLayer created above. These layers will be blended together to create the underlying style for the map. The vector tile layer provides the base colors and the image tile layer provides the hillshade or topographic effect.

In the main function, create a Basemap object and add vectorTileLayer and the imageTileLayer to the baselayers array.

        zoom: 3

      });

Run the app

In CodePen, run your code to display the map.

The map view should display the Forest and Parks Canvas vector tile layer on top of the World Hillshade image tile layer. The styled vector tile layer is displayed on top of the hillshade terrain.
