For LineOfSightOperator and its derived classes TargetLineOfSightOperator and AirspaceCoverageOperator, the SensorHeight is in relation to a carrier, meaning that the observer's total height is the sum of SensorHeight and the carrier's height; see LineOfSightOperator.CarrierType.

On the other hand, the VisibilityIndexOperator is less flexible since it lacks the carrierType property, and it will always interpret the SensorHeight as the observer's total height above the reference level given by ObserverHeightType.
