View inWPFWinUIMAUIUWPView on GitHub
Set the map view to a new 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
- 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.
