Change the basemap style (v1)

Learn how to change a basemap layer from the basemap styles service using MapLibre GL JS.

The basemap styles service (v1) provides a number of basemap layer styles such as topography, streets, 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 Developer or ArcGIS Online account to access the developer dashboard and create an API key.

Steps

Create a new pen

Go to CodePen to create a new pen for your application.

Set the API key

To access location services, you need an API key or OAuth 2.0 access token. To learn how to create and scope your key, visit the Create an API key tutorial.

Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial.

In CodePen, update apiKey to use your key.

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

Add a selector

Create a <div> tag to contain the <select> dropdown menu. Add a basemap layer enumeration for each <options></options> element.

In the <style> element, add CSS styling to the basemaps-wrapper and basemaps.

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.

        // Instantiate the given basemap layer.
        map.setStyle(url(name));
      };

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:Streets.

      setBasemap("ArcGIS:Streets");

Run the app

In CodePen, run your code to display the map.

You should be able to use the select element to switch between basemap layers.
