Display a map

Learn how to create and display a map with a basemap layer.

A map contains layers of geographic data. Maps include a basemap layer and, optionally, one or more data layers. You can display a specific area of a map by setting the location and zoom level.

This tutorial shows you how to create and display a map of the Santa Monica Mountains in California using the topographic basemap layer.

The map and code in this tutorial will be used as the starting point for other 2D tutorials.

Prerequisites

Steps

Create a new pen

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

Add basic HTML

Define a basic HTML page.

  1. In CodePen > HTML, add HTML to create a basic page.

Get an access token

You need an access token with the correct privileges to access the location services used in this tutorial.

  1. Go to the Create an API key tutorial and create an API key with the following privilege(s):
    • Privileges
      • Location services > Basemaps
  2. In CodePen, set esriConfig.apiKey to your access token.

    <script>
    
      var esriConfig = {
        apiKey: "YOUR_ACCESS_TOKEN"
      };
    
    </script>

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

Add references

  1. In the <head>, add the <script> and <link> tags for the Map Components and the Calcite Design System.

Add a map

Use the Map component to set the basemap layer, location and zoom level.

  1. In the <body> tag, add the <arcgis-map> component and specify the basemap, center and zoom attributes.

Run the app

In CodePen, run your code to display the map.

The map should display the topographic basemap layer for an area of the Santa Monica Mountains in California.
