OGC TimeseriesML 1.2 is an OGC Standard. Copyright (c) 2015, 2016, 2019 Open Geospatial Consortium. To obtain additional rights of use, visit http://www.opengeospatial.org/legal/ . The Time Value Pair (TVP) Encoding schema contains types suitable for encoding TimeSeries (both Measurement and Categorical) in a sequence of time, value pairs. Note that this time, value pair encoding of timeseries encoding takes the name 'Timeseries'. The domain range encoding equivalent takes the name TimeseriesDomainRange. CategoricalTVP is the encoding for time,value pairs where the value is a category. The categorical value of the data point (e.g. 'High') MeasurementTVP is the encoding for time,value pairs where the value is a measure. The measurement value for this data point (e.g. 5.3m) The core class for the timeseries time, value pair encoding. Metadata about the timeseries Default metadata for each point in the timeseries (can be over-ridden on a per-point basis). Data points (time, value pairs) for the timeseries. A base class for different time, value pair implementations. Point metadata for this point (over-rides any default point metadata for the timeseries). Time component of the time value pair. (A point on the timeseries). gml:MeasureType supports recording an amount encoded as a value of XML Schema double, together with a units of measure indicated by an attribute uom, short for "units Of measure". The value of the uom attribute identifies a reference system for the amount, usually a ratio or interval scale. OGC TimeSeriesML alters this definition to make uom optional as this value is defaulted for a series.
