    Notes:

    GeopositionAccuracy has two settings (source):

    • Default – Optimize for power, performance, and other cost considerations.

    • High – Deliver the most accurate report possible. This includes using services that might charge money, or consuming higher levels of battery power or connection bandwidth.

    Manipulation Events (source):

    • ManipulationStarted – This event occurs when the user starts a direct manipulation by placing their finger or fingers on the screen.
    • ManipulationDelta- This event occurs repeatedly while the user is moving their finger or fingers on the screen.
    • ManipulationCompleted- This event occurs when the user removed their finger or fingers from the screen
