SensorThings Entity names

NMBGMR Ground Water Levels

Items in <> are field names in the source dataset, i.e. crosswalk.

Items in italics are literals

SensorThings Entity	Name	Description	Properties (additional metadata associated with each entity)
Location	<PointID>Jake Ross where does location X y coordinate go? And where does date/time go?	Site where measurements are made (in this case groundwater level measurement below land surface)	`AltDatum`= <AltDatum> `Altitude`= <Altitude> Source of Alt (Ie. DEM or survey)
Thing	`Water Well`	Well drilled or set into subsurface for the purposes of pumping water or monitoring groundwater	`WellDepth`=<WellData.WellDepth> `GeologicFormation`=<WellData.FormationZone> `ScreenTop`= <WellScreens.ScreenTop> `ScreenBottom`=<WellScreens.ScreenBottom>
Datastream	`Groundwater Levels`	Measurement of static groundwater depth in a water well, as measured below land surface	`Agency= NMBGMR`
ObservedProperty	`Depth to Water Below Land Surface`	`depth to water below land surface` (NOTE: THIS IS NOT ELEVATION of Water, if elevation is reported, depth to water below land surface must be calculated using land elevation and measuring point.)	Option of Null, Dry, or qualifications on observed property
Sensor	`Pressure`	`Continuous measurement depth to water in Feet below ground surface (converted from pressure reading and QC’ed from depth below land surface in feet)`
Sensor	`Acoustic`	`Continuous measurement depth to water in Feet below ground surface (converted from acoustic device, QC’ed)`
Sensor	`Manual`	`Manual measurement of groundwater depth by steel tape or electronic probe or other`	`MeasurementMethod`=<LU_MeasurementMethod.Meaning>
