Change the basemap style

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

The basemap styles service provides a number of ArcGIS and OSM basemap layer styles such as topography, navigation, outdoors, and imagery that you can use in maps.

In this tutorial, you will use a Calcite Combobox to select and display different basemap styles.

Prerequisites

Steps

Create a new pen

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

Get an access token

You need an access token with the correct privileges to access the location services 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

In CodePen, set esriConfig.apiKey to your access token.

Use dark colors for code blocks
  var esriConfig = {
    apiKey: "YOUR_ACCESS_TOKEN"
  };

To learn about other ways to get an access token, go to Types of authentication.

Create a basemap style function

In a new <script> at the bottom of the <body>, create a function that accepts a basemap style id and updates the map to the corresponding basemap style.

Define a new updateBasemapStyle function that accepts a style id and updates the current basemap.

    <script>

      const updateBasemapStyle = (basemapId) => {
        document.querySelector("arcgis-map").basemap = basemapId;
      };

    </script>

Add a Calcite combobox to change the basemap style

Reference additional basemap styles you would like to use in your application. Use a Calcite combobox to change the basemap style.

Create a Placement component to add the combobox to the top-right corner of the map.

    <arcgis-map basemap="arcgis/topographic" center="-118.805, 34.027" zoom="13">
      <arcgis-zoom position="top-left"></arcgis-zoom>

      <arcgis-placement position="top-right">

      </arcgis-placement>

    </arcgis-map>

Create a HTML div element with a calcite label and combobox component with the basemap styles.

Run the App

In CodePen, run your code to display the map.

Use the Calcite combobox in the top right to select and explore different basemap styles from the Basemap styles service (v2).
