Observation
- Description
- The determination of the value of a particular characteristic of an Object at a given time or between two times.
- Properties
- For this entity the following properties are defined: featureOfInterest, hasSimpleResult, hasUltimateFeatureOfInterest, madeBySensor, metadata, observedProperty, parameter, phenomenonTime, relatedObservation, result, resultQuality, resultTime, usedProcedure.
| Property | Expected Range | Cardinality | Description | Usage | Codelist |
|---|---|---|---|---|---|
featureOfInterest
|
Feature | 1 | Object that is observed. | Can be the Feature itself or a proxy, viz a SamplingFeature. REMARK: Sometimes the actual FeatureOfInterest is only determined after observing the proxy. | |
hasSimpleResult
|
Literal | 1 | The simple value of an Observation or Actuation. | ||
hasUltimateFeatureOfInterest
|
Feature | 1..* | Link to the ultimate feature of interest of an observation or act of sampling. This is useful when the proximate feature of interest is a sample of the ultimate feature of interest, directly or transitively. | ||
madeBySensor
|
Sensor | 1 | Relation between an Observation and the Sensor which made the Observations. | ||
metadata
|
Metadata | 0..1 | Link to the metadata of the observation. | ||
observedProperty
|
PropertyType | 1 | Relation linking an Observation to the property that was observed. The ObservableProperty should be a property of the FeatureOfInterest (linked by hasFeatureOfInterest) of this Observation. | ||
parameter
|
NamedValue | 0..* | The parameter describes an arbitrary event-specific parameter. This might be an environmental parameter, an instrument setting or input, or an event-specific sampling parameter that is not tightly bound to either the feature of interest or to the observation procedure. | ||
phenomenonTime
|
TM_Object | 1 | Phenomenon time describes the time that the result applies to the property of the feature of interest. This is often the time of interaction by a sampling procedure or observation procedure with a real-world feature. | ||
relatedObservation
|
Observation | 0..* | Observations of which the results are related in one way or another | ||
result
|
Result | 1 | Estimate of the value of a property determined through a known observation procedure | ||
resultQuality
|
DQ_Element | 0..* | The resultQuality describes the quality of the result. This instance-specific description complements the description of the observation procedure, which provides information concerning the quality of all observations using this procedure. Quality of a result may be assessed following the procedures in ISO 19114:2003. | ||
resultTime
|
DateTime | 1 | The resultTime describes the time when the result became available, typically when the procedure associated wit hthe observation was completed. For some observations this is identical to the phenomenonTime. Howevere there are important cases where they differ. | ||
usedProcedure
|
ObservationProcedure | 0..* | A relation to link to a re-usable Procedure used in making an Observation, an Actuation, or a Sample, typically through a Sensor, Actuator or Sampler. |
ObservationCollection
- Description
- A collection of one or more observations,whose members share a common value for one or more properties.
- Properties
- No properties have been defined for this entity.
ObservationProcedure
- Description
- A workflow, protocol, plan, algorithm, or computational method specifying how to make an observation, create a sample, or make a change to the state of the world (via an actuator). A procedure is re-usable, and might be involved in many observations, samplings or actuations. It explains the steps to be carried out to arrived at reproducible results.
