The Map Viewer allows you to interactively style and configure maps by setting the basemap layer, data layers, layer styles, pop-up settings, and layer visibility ranges. All of the settings are stored as JSON in an itemAn item, also known as a content item, is a resource stored in a portal such as a web map, hosted layer, style, script tool, file, or notebook.Learn more. A number of ArcGIS applications and APIs can access web map items, read the JSON, and then re-create the original scene.

Steps

Set the basemap layer

To create a web mapA web map is a map stored as a JSON object that defines properties such as the basemap layer, data layers, layer styles, and pop-up styles. Its JSON structure is defined by the web map specification.Learn more with the Map ViewerMap Viewer is a browser-based mapping tool that can view, create, and save web maps.

2. In the left-panel, click Basemap > Current Basemap > Streets.

3. In the left-panel, click Basemap to close the window.

1. In the left-panel, click Add > Add layer from URL.

2. For each URL:

   • Copy and paste the URL > Add to map.
     • Parks and Open Space: https://services3.arcgis.com/GVgbJbqm8hXASVYi/ArcGIS/rest/services/Parks_and_Open_Space/FeatureServer/0

3. Click Save. At a minimum, you need to provide a title and tags for your web map.

Your web map should look something like this.
