The IsLayerVisibleAtScale method, called by the TOCControl, returns whether the specified layer is visible at the specified scale.

A layer in a globe has IGlobeLayerProperties::MinimumDistance and IGlobeLayerProperties::MaximumDistance properties. The IsLayerVisibleAtScale method allows the GlobeControl to override the ILayer::MinimumScale and ILayer::MaximumScale properties with the MinimumDistance and MaximumDistance properties to correctly manage the visibility of the layer.
