        dct:description  "SIGMETPositionAnalysis (a subclass of SamplingObservation from METCE) is intended for use when reporting the forecast position of meteorological conditions hazardous to flight. The result of this observation type shall refer to one or more MeteorologicalPositions which represents the forecast positions of SIGMET phenomena. SIGMETPositionAnalysis enforces the following additional constraints: ‘featureOfInterest’ shall refer to an entity of type SF_SamplingSurface and the associated ‘sampledFeature’ must be an airspace."@en .
