-- Name -- Point Observation -- Definition -- Observation that represents a measurement of a property at a single point in time and space. -- Description -- The PointObservation represents a single measurement or estimation of a property at a single point in time and space. For example a single temperture measurement at a fixed weather station.
-- Name -- PointTimeSeriesObservation -- Definition -- Observation that represents a time-series of point measurements of a property at a fixed location in space -- Description -- A PointTimeSeriesObservation is a time series of observations made at the same fixed spatial location e.g. Measurements made repeatedly by a fixed monitoring instrument.
-- Name -- PointObservationCollection -- Definition -- A collection of Point Observations. -- Description -- The PointObservationCollection is a collection of separate PointObservations. In the case where it is useful to group together a set of otherwise independent PointObservations the PointObservationCollection should be used to make this grouping. The grouping may be made on any basis e.g. it may be useful to group together PointObservations made by the same instrument or Environmental Facility, or in a particular measurement campaign. Each member of the PointObservationCollection must be a single PointObservation.
-- Name -- MultiPointObservation -- Definition -- Observation that represents a set of measurements all made at exactly the same time but at different locations -- Description -- The MultiPointObservation is an Observation that represents a set of measurements all made at exactly the same time but at different locations, for example a distributed sensor network reporting the temperature at 10am. The result of this observation is a MultiPointCoverage.
