Use case

Programatically navigate to a specified location in the map or scene. Use this to focus on a particular point or area of interest.

How to use the sample

The map view has several methods for setting its current viewpoint. Select a viewpoint from the UI to see the viewpoint changed using that method.

How it works

Create a new Map object and set it to the MapView object.
Change the map's Viewpoint using one of the available methods:

Use MapView.SetViewpointAsync() to pan to a viewpoint.
Use MapView.SetViewpointCenterAsync() to center the viewpoint on a Point.
Use MyMapView.SetViewpointScaleAsync() to set a distance from the ground using a scale.
Use MapView.SetViewpointGeometryAsync() to set the viewpoint to a given Geometry.
