Diversion Volumes

Table 1: The STA data model definitions and example mappings to NM agency datasets regarding points of diversion measurements

	SensorThings Entity	Description	Diversion Volumes Example: NMOSE Water - Points of Diversion

	SensorThings Entity	Description	Diversion Volumes Example: NMOSE Water - Points of Diversion
Metadata	Location	A unique coordinate or area on the surface of the earth	Location in easting and northing (UTM NAD83 in meters)
	Thing	Some real-world entity with which one or more Sensors are associated	Point of Diversion POD Number A 00008 AS
	Datastream	A collection of Observations about an ObservedProperty produced by a Sensor associated with a Thing	Meter Readings (Quarterly)
	Datastream/observationType	The type of observation, codified in the Observations and Measurements data standard. Types include Categorical (defined text), Count (integer), Measurement (continuous number), Observation (free text), and TruthObservation (True/False)	Measurement
	Datastream/unitOfMeasurement	A three-item definition of the unit of measurement, including its name, symbol, and link to the definition (preferably to one provided in an established ontology such as http://unitsofmeasure.org/ucum.html or http://qudt.org/)	Acre-Feet (e.g. http://qudt.org/vocab/unit/AC-FT)
	Sensor	The procedure used to provide a Datastream. Can be a particular data recording device model, or a defined procedure followed by a human observer. If applicable, a specific instance (e.g. a sensor model and serial number)	MCCROMETER Diversion Meter-Meter Number 17147
	ObservedProperty	The raw or processed phenomenon (quantitative or qualitative) being measured for the Datastream. Preferably including a link to a definition provided by an established ontology or controlled vocabulary such as the ODM2 Controlled Vocabularies or http://qudt.org/)	Mtr Amount
	OPTIONAL: FeatureOfInterest	The real-world feature that the Observations are about. This may or many not be different from the Location where the Thing on which the Sensor is mounted. Can include a JSON-formatted point location or a polygon or collections thereof.	Water Right (set of relevant points of diversion)
Data	Observation	A single measurement value including the result, time values, and other metadata. Information on the ObservedProperty that was measured by what Sensor is provided by the Datastream these observations are in. Features of Interest are linked for each observation as well. Observations are linked to (collected in) Datastreams	Meter Reading
	Observation/result	The actual measured value, with valid values defined in observationType and units defined in unitsOfMeasurement, both provided by Datastream	Mtr Amount (e.g. 107.948)
	Observation/phenomenonTime	The date+time (or interval) in ISO 8601 format (YYYY-MM-DDT:HH:MM:SS-Z) when the observation occured	1/20/2017-04/05/2017 (Quarterly period for which volume was measured)
	OPTIONAL: Observation/resultTime	The date+time that the result was generated. May be the same as phenomenonTime	04/05/2017 (date of meter reading)
	OPTIONAL: Observation/validTime	The date+time interval during which the Observation can be used (often used for provisional values that are replaced by QA/QC’d observations)
	OPTIONAL: Observation/resultQuality	A description of the result Quality. Will vary according to agency practice. Can use ODM2 controlled vocabulary for data quality types as a guide.
