Display overview map

Include an overview or inset map as an additional map view to show the wider context of the primary view.

Use case

An overview map provides a useful, smaller-scale overview of the current map view’s location. For example, when you need to inspect a layer with many features while remaining aware of the wider context of the view, use an overview map to help show the extent of the main map view.

How to use the sample

Pan or zoom across the map view to browse through the tourist attractions feature layer and watch the viewpoint or scale of the linked overview map update automatically.

How it works

1. Create a Map with the arcGISTopographic basemap style.
2. Create a MapView instance with the map.
3. Instantiate a FeatureLayer and add it to the map’s operational layers.
4. Create an OverviewMap object using the toolkit.
5. Add the OverviewMap to the map view as an overlay.
