observerOffsetZ

The location offset applied to the observer com.arcgismaps.mapping.GeoElement in the Z direction. The observer location is determined by the location of the com.arcgismaps.mapping.GeoElement plus any defined offsets (in X, Y, or Z). The offset position of the observer relative to the com.arcgismaps.mapping.GeoElement is always maintained, even when the com.arcgismaps.mapping.GeoElement moves.
