Metadata

Location

A unique coordinate or area on the surface of the earth

CN=county code;

COUNTY

RVB=river basin;

GWB=ground water basin

(also have state-level values)

Are lat/lon captured within data? or require merging with another dataset?

Thing

Some real-world entity with which one or more Sensors are associated

(Analogous to Location?)

Datastream

A collection of Observations about an ObservedProperty produced by a Sensor associated with a Thing

Time series, Hydrograph

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/)

ac-ft; gallons; %

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)

Data Synthesis

Some data collected from WATERS/meters; are efficiency/acreage values provided within WATERS?

Additional details about how data is collected?

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/)

GPCD=gallons per capita per day;

WSW=withdrawal, surface water; (ac-ft)

WGW=withdrawal, ground water; (ac-ft)

TW = withdrawal, total (ac-ft)

MSW= percent of surface water withdrawals measured;

MGW=percent of groundwater withdrawals measured;

MTW=percent of total withdrawals that were measured

TFSW=total farm withdrawal, surface water

CLSW=surface water conveyance losses from stream or reservoir to farm headgate

TPWSW=total project withdrawals, ssurface water

TPWGW=total project withdrawals, ground water.

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.

Population (number of people or %)

For Livestock: User (e.g., Cattle, Chickens, etc.)

For Reservoir: CAPACITY=total storage capacity (acre-feet); SAS=surface area at spillway elevation; SAA=surface area, average; EGR=gross evaporation rate in feet/year; R=rainfall in feet/year; ENR=net evaporation rate in feet/year

For Power: User (e.g., PNM, Xcel, …), Power Generated (units? kWh?)

For Domestic: WEC = water exchange code

For Tables: Category (PWS, Domestic, …)

For Table 7: WWC = water withdrawal code; WEC = water exchange code

For Table 8: T=type of irrigation system, i.e., drip (D), flood (F), or sprinkler (S); ASWO=acreage irrigated with surface water only; AGWO=acreage irrigated with ground water only; ASWC=surface water component of acreage irrigated with combined water, i.e., both surface and ground water; AGWC=ground water component of acreage irrigated with combined water; TAI=total acreage irrigated;

For Table 12: T=type of irrigation system, i.e., drip (D), flood (F), or sprinkler (S); CIRSW=consumptive irrigation requirement for acreage irrigated with surface water (units: ac-ft?); CIRGW=consumptive irrigation requirement for acreage irrigated with ground water (units: ac-ft?); ASWO=acreage irrigated with surface water only; AGWO=acreage irrigated with ground water only; ASWC=surface water component of acreage irrigated with combined water, i.e., both surface and ground water; AGWC=ground water component of acreage irrigated with combined water; TAI=total acreage irrigated; EF=on-farm irrigation efficiency (units: fraction/dim-less?); EC=off-farm conveyance efficiency (units: fraction/dim-less?); Ep=project efficiency (units: fraction/dim-less?);

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

Volume or Rate

(For Table 1, Pop is the observation - how to best reconcile info within different tables, or do we have a separate data feed for each table?)

(For Tables 9-11 - acreage is the observation…would we include this as a sep stream or more as metadata?)

Observation/result

The actual measured value, with valid values defined in observationType and units defined in unitsOfMeasurement, both provided by Datastream

GPCD (10)

Pop (1,916)

WSW (4.29)

WGW (17.17)

TW (284,157)

MSW (93.24%)

MGW (82.97%)

MTW (85.38%)

TFSW (9395)

CLSW (5632)

TPWSW (15027)

TPWGW (67684)

Observation/phenomenonTime

The date+time (or interval) in ISO 8601 format (YYYY-MM-DDT:HH:MM:SS-Z) when the observation occured

2015

OPTIONAL: Observation/resultTime

The date+time that the result was generated. May be the same as phenomenonTime

How many years after 2015 was the report generated? 2018?

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)

2010-2015 - reflecting the 5 years prior? As of end of 2015 - inclusive?

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.

Diversion and meter data requires QAQC to remove duplicates and irrelevant entries

Some entries (e.g., Table 12) contains N/A=not applicable, no acreage was reported; - - =due to report format efficiency not provided.
