Extends EOP EarthObservationEquipment for Altimetry products The instrument is the main instrument used to obtain the data. In the case of combined products there may be more than one main instrument. The cardinality is therefore zero to many. As well as the altimeter, one or more auxiliary instruments may be used for an acquisition. Auxiliary Instruments are a class of instrument that are not the primary instrument. e.g. the DORIS-DIODE doppler system is an auxiliary instrument that works alongside an altimeter. In the case of combined products there may be more than one platform. The cardinality of the platform is is therefore zero to many. Extends the EOP Footprint for along track data used in Altimetry products. A geometry of type GM_Multicurve is used to define the nominal track on the earths surface. This track is essentially a line that is representative of the product but does not include points for every value. The use of GM_MultiCurve allows for multiple lines and breaks in lines. In future wide-swath altimetry cases (e.g. SWOT) where the track will be a swath, the multiExtentOf property in the base schema may be used (as it is for other EO products). Extends eop:EarthObservation for Altimetry products Extends EOP EarthObservationMetadata for Altimetry products the value of the processing property should be the extended alt:ProcessingInformation Extends EOP Acquisition for Altimetry products Number of cycle. Acquisition may not be a pass but may be a segment characterised by a start and end time. In this case the isSegment flag should be set to "True" The default value (or the assumed value if not present) is "False" Pass number since start of cycle. Auxiliary Instruments are a class of instrument that are not the primary instrument. e.g. the DORIS-DIODE doppler system is an auxiliary instrument that works alongside an altimeter. The type of the auxiliary instrument e.g. Doppler, Laser, GPS. Must be taken from the codeList AuxiliaryInstrumentType Extends EOP ProcessingInformation for Altimetry products. Measure of the uncertainty of the ground track. Sometimes known as deadband e.g. 1Km deadband. Classification of product according to ground type covered. Value of this property must be taken from the enumeration ProductContentsTypeValue. Note cardinality allows for multiple instances of this property. Rate at which samples are provided in product. Some products may contain more than one sampling rate, e.g. 1kHz and 20kHz. Cardinality is therefore zero to many.
