Change viewpoint

This code sample is available for these platforms:
View Sample on GitHub

Set the map view to a new viewpoint.

Image of change viewpoint

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:
  • 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.

Relevant API

  • Geometry
  • Map
  • MapView
  • Point
  • Viewpoint

Additional information

Below are some other ways to set a viewpoint:

  • SetViewpoint
  • SetViewpointAsync
  • SetViewpointCenterAsync
  • SetViewpointGeometryAsync
  • SetViewpointRotationAsync
  • SetViewpointScaleAsync


animate, extent, pan, rotate, scale, view, zoom
