-- Name --
GridObservation
-- Definition --
Observation representing a gridded field at a single time instant.
-- Description --
A GridObservation is an observation of some phenomenon (or phenomena) over a gridded field. E.g. Output from a model, or rectified, georeferenced satellite data.
The result of a GridObservation is a discrete coverage within a compound spatiotemporal CRS where the domain consists of a two- or three-dimensional grid of points, all having the same time instant temporal component.
-- Name --
GridSeriesObservation
-- Definition --
Observation representing an evolving gridded field at a succession of time instants.
-- Description --
A GridSeriesObservation is a time series of gridded fields representing the same phenomenon (or phenomena) over a series of times. E.g. Ocean model output.
The result of a GridSeriesObservation is a discrete coverage within a compound spatiotemporal CRS where the domain consists of a series of two- or three-dimensional grids of points, each at a successive time instant.
-- 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.
-- 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 --
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 --
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 --
ProfileObservation
-- Definition --
Observation representing the measurement of a property along a vertical profile in space at a single time instant.
-- Description --
A ProfileObservatation is an Observation representing the measurement of a property along a vertical profice in space at a single time instant. For example a CTD profile measuring salinty at different depths in the ocean.
-- Name --
TimeLocationValue Triple
-- Definition --
A triple set of Time, location, value (measurement). For example, at a point along a trajectory.
-- Name --
location
-- Definition --
Geographic location where value is valid.
-- Name --
TrajectoryObservation
-- Definition --
Observation representing the measurement of a property along a meandering curve in time and space.
-- Description --
A TrajectoryObservatation is an Observation representing the measurement of a property along a meandering curve in time and space. For example a Pollutant concentration from a mobile air quality sensor.
