Requirement
reqxsd-measurement-timeseries-tvpinterpolation-type The interpolation type of each point shall be specified at each point using the
interpolationType element or through the use of the defaultPointMetadatainteropolationType element.
Requirement
reqxsd-measurement-timeseries-tvpvalue-measure The type of the wml2:point element shall be wml2:MeasurementTVP.
Requirement
reqxsd-measurement-timeseries-tvpunit-of-measure Every value within the time series must have a unit of measure specified,
either explicitly or from a specified default.
Requirement
reqxsd-measurement-timeseries-tvptimeseries-metadata The type of the wml2:metadata element shall be
wml2:MeasurementTimeseriesMetadata.
Requirement
reqxsd-measurement-timeseries-tvppoint-metadata The type of the wml2:pointwml2:MeasurementTVPwml2:metadata element
shall be wml2:TVPMeasurementMetadata.
The following timeseries shows an example of an equidistant coding of a time series, using default point-metadata and a nil value. The measurements occur at 12:27:00, 12:28:00 and 12:29:00. The measurement expected at 12:29:00 is missing. The
temporal extent of the time series runs from 12:27:00 to 2:30:00.
