The overview map is a small map that is inset in the main map. Often the overview map shows the main map in its larger context. The overview map is synchronized with the main map. When the user pans or zooms the main map, the overview also pans and zooms. The end user can show and hide the overview map.

An overview map is not recommended for most modern applications, as it is easy to zoom out for quick context. One exception is a map that opens to a specific feature of interest—for example, a property parcel—from a third-party system, where the user has no idea where the feature is located and has no other reason to zoom out.
The overview map is fully configurable. You can add and remove map services and feature layers, edit display settings, and add and remove layers, just as you do when you configure the main map.
The spatial reference of the overview map must match the spatial reference of the map.
