Display a web map

Learn how to display a map from a web map stored in ArcGIS.

A web map is a map stored as an item in ArcGIS Online. A web map item contains all of the configuration settings for the map (in JSON format) such as the basemap layer, data layers, layer styles, and pop-up settings. Applications can access and display a web map using its item ID.

In this tutorial, you will load and display a pre-configured web map stored in ArcGIS Online.

Prerequisites

Steps

Create a new pen

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

Add basic HTML

Define a basic HTML page.

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

Use dark colors for code blocks

Run the App

In CodePen, run your code to display the map.

You should now see a map with trails and parks in the Santa Monica Mountains, along with a legend that displays layer information contained in the web map.
