The overview map itself will be 2D only. For a 3D overview map, we will have a separate component called "overview scene" which will be prioritized separately
The "main" geoview of the app can be either 2D map or 3D scene
The overview map indicator should show the current view
As your main geoview's viewpoint changes, the overview map is updated automatically
The scale/LOD of the overview map should update automatically as the user zooms in on the main map. For example, If you are looking at a city level, we don't want the overview map to be at the World level - it should be somewhere around state or country level (depending on size of state/country)
Extent indicator is a red solid line by default
Basemap is the Esri Topographic Vector Basemap by default
Works with API Keys
On mobile, the overviewmap's touch/click events should be ignored (no user panning or zooming) - it is for reference only. On Desktop, it will update the main map's viewpoint
works across the dateline (likely need to normalize geometry)
works if map is rotated
Nice-to-haves (Moderate Priority)
The overview map's basemap can be changed/specified
The overview map's extent indicator should be customizable
Min-ship (High Priority)
Nice-to-haves (Moderate Priority)
