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

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
});

Create a basemap style function

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.

      const updateBasemapStyle = (basemapId) => {
        view.map.basemap = basemapId;
      };

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.

Add references to Calcite components in the <head> tag.

Use dark colors for code blocks
  <script type="module" src="https://js.arcgis.com/calcite-components/2.5.1/calcite.esm.js"></script>
  <link rel="stylesheet" type="text/css" href="https://js.arcgis.com/calcite-components/2.5.1/calcite.css" />

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

Add an event listener to watch for changes on the combobox. When the combobox value has changed, call the updateBasemapStyle function to update the basemap style.

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).
