If the geography is a LineString, it may use the Z element of the GeoJSON spec to specify altitude changes during flight.

+The regulatory identifier provides an optional, generic object for immediately identifying operators and hardware to regulatory bodies. In the case that a regulatory body will not permit an operation without embedded identifying information, this object may be used. Fields within the object are all optional; it is up to the submitting user and involved UTM network managers to ensure that the provided information is sufficient for a given jurisdiction.
