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. wml2:MeasurementTimeseries gml:id = xsd-measurement-timeseries-tvp.example gml:description Example timeseries for XML encoding http:www.opengis.netspecwaterml2.0reqxsd-timeseries-time-value-pair gml:description wml2:metadata wml2:MeasurementTimeseriesMetadata wml2:temporalExtent gml:TimePeriod gml:id = time-period.1 gml:beginPosition 2011-11-21T12:27:00+10:00 gml:beginPosition gml:endPosition 2011-11-21T12:30:00+10:00 gml:endPosition gml:TimePeriod wml2:temporalExtent wml2:baseTime 2011-11-21T12:27:00+10:00 wml2:baseTime wml2:spacing PT1M wml2:spacing wml2:MeasurementTimeseriesMetadata wml2:metadata wml2:defaultPointMetadata wml2:DefaultTVPMeasurementMetadata wml2:uom code = m wml2:interpolationType xlink:href = http:www.opengis.netdefwaterml2.0interpolationTypeContinuous xlink:title = Instantaneous wml2:DefaultTVPMeasurementMetadata wml2:defaultPointMetadata
