Change the basemap style

Learn how to change a basemap style in a map using the basemap styles service.

The basemap styles service provides a number basemap layer styles such as topography, streets, outdoor, navigation, and imagery that you can use in maps.

In this tutorial, you use a <select> dropdown menu to toggle between a number of different basemap layer styles.

Prerequisites

You need an ArcGIS Location Platform or ArcGIS Online account.

Steps

Create a new pen

To get started, you can complete the Display a map tutorial or use the .

Get an access token

You need an access token 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
Copy the API key access token to your clipboard when prompted.

In CodePen, update the accessToken variable to use your access token.

Use dark colors for code blocks
const accessToken = "YOUR_ACCESS_TOKEN";
const basemapEnum = "arcgis/outdoor";
const map = new maplibregl.Map({
  container: "map", // the id of the div element
  style: `https://basemapstyles-api.arcgis.com/arcgis/rest/services/styles/v2/styles/${basemapEnum}?token=${accessToken}`,
  zoom: 12, // starting zoom
  center: [-118.805, 34.027] // starting location [longitude, latitude]
});

Run the code to ensure the basemap is displayed in the map.

To learn about the other types of authentication available, go to Types of authentication.

Add a selector

Create a <div> tag to contain the <select> dropdown menu. Add basemap layer enumerations from the v2 basemap styles service as <option>s.

Set the basemap

Use a function to reference the basemap styles service and a style enumeration to update the map. This will be used when a selection is made.

Create a baseUrl and a url element. The url element will append the name of the basemap selected from the dropdown menu.

Run the code to ensure that the <select> element contains different basemap enumerations.

Add an event listener

Use an event listener to register a basemap change in the <select> element and to update the map.

Set the default basemap to arcgis/outdoor.
