10.6 Requirements Class: Measurement time-value pair Timeseries interleaved Observation
Requirements Class http:www.opengis.netspecwaterml2.0reqxsd-measurement-timeseries-tvp-
observation

Requirement
reqxsd-measurement-timeseries-tvp-observationresult The xml element om:result shall have a value that matches the content model
defined by wml2:MeasurementTimeseries.
The example below shows a measurement timeseries observation with appropriate metadata, phenomenon time, procedure and result elements. The result uses an interleaved timeseries time-value pair encoding which references the example in listing
XML Example 3 for brevity.

10.8 Requirements Class: Timeseries – time-value pair representation
This requirements class describes the structure of the interleaved timeseries. The structure supports time-value pair representation with the ability to associate metadata on a point-by-point
basis. This class satisfies both the core timeseries requirements class and the time-value pair representation as described in sections 9.12 and 9.14 respectively.
