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

  1. Create a new Map object and set it to the MapView object.
  2. Change the map's Viewpoint using one of the available methods:
  3. Use MapView.SetViewpointAsync() to pan to a viewpoint.
  4. Use MapView.SetViewpointCenterAsync() to center the viewpoint on a Point.
  5. Use MyMapView.SetViewpointScaleAsync() to set a distance from the ground using a scale.
  6. Use MapView.SetViewpointGeometryAsync() to set the viewpoint to a given Geometry.
