For level measurements this indicates the type of reference point the level is measured from. Can be relative to the Ordnance Survey datum (rt:AOD), to a local stage datum (rt:ASD) or rt:BDAT (below datum?).

If true indicates that high resolution data from this station may updated directly from a telemetry feed and so has less latency that data only received via wiski services

A name for the item

A string or other literal which uniquely identifies the item.

Indicates the nature of the observations in a dataset, for example raw measured v.s. quality controlled

A name for the item

A name for the item

Short, cannonical, name of the quantity being measured e.g. "level", "flow" or "temperature".

The name of the quantity being measured e.g. "Water Level", "Flow", "Temperature"

The period between successive readings, in seconds.

Name for the period, e.g. 'Daily', may use 'subdaily' to present a mix of e.g. hourly and 15min sampling

A qualilfier for the quantity being measured. Most common use is to separate level measures which occur at the top ("Stage") or bottom ("Downstream Stage") of a sluice or weir. Other relevant qualifiers are "Tidal Level" and "Groundwater".

The URI of the monitoring station supplying the measure

Identifier for the station, as used by River Levels On the Internet.

A name for the item

Identifier for the telemetry feed used by the Environment Agency's National Flood Forecasting System

Identifier for the station in the WISKI hydrology dataset

Unique identifier for this timeseries

The units in which this parameter is measured, e.g. qudt:Meter

A name for the units for this measurement including the datumType. Typical values are mAOD (for meters relative to the Ordnance Survey datum), mASD (for meters relative to the local stage datum), m (for meters with an unspecified datum) and m3/s (for flow rates).

Indicates whether the values in a time series represent mean, min, max, instananteous or other statistics over the measurement interval.

A name for the item

Indicates whether the measured value is an instantaneous reading or a total, mean or maximum over the period.

Lets you return a subset of properties that are specified by the endpoint view. All the properties returned by an endpoint are defined in the model below.

Return only a given number of items from the list, some endpoints may impose a default limit and/or a maximum to which the limit can be set. In particular, sampling points, samples and measurements default to a soft limit of 50 items but that can be overridden.

Return the list of items starting with the xth item, together with _limit this enables paging through a long set of results. Though it often cheaper to simply return all that you want in one go or to use filters to reduce the list to a subset of interest.

Reorder the list of returned results by the value of the named property of the results. Use -{property} to sort in descending instead of ascending order. Multiple sort parameters can be given.
