Change the basemap layer

Learn how to change the basemap layer in a map.

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

In this tutorial, you will use the Basemap Toggle and BasemapGallery widgets to select and display different basemap layers.

Prerequisites

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

Steps

Create a new pen

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

Set the API key

To access ArcGIS services, you need an API key.

  1. Go to your dashboard to get an API key.

  2. In CodePen, set the apiKey to your key, so it can be used to access basemap layer and location services.

    const map = new Map({
      basemap: "arcgis-topographic" // Basemap layer service
    });

Add modules

  1. In the require statement, add the Basemap Toggle and BasemapGallery modules.

Toggle between basemaps

An easy way to enable selection between two basemaps is to use the Basemap Toggle widget. Use the widget to toggle between arcgis-topographic and arcgis-imagery basemaps.

  1. Create a Basemap Toggle and set the view. Set the nextBasemap property to arcgis-imagery.

  3. Switch between basemaps.

You can also use the BasemapGallery widget to select different basemaps.

  1. Create a BasemapGallery and set the query in the source property to search for the "World Basemaps for Developers" basemap group.

Run the App

In CodePen, run your code to display the map.

You should have two widgets in your application that provide different ways to choose basemaps.
