Class ComplexSamplingMeasurement (a subclass of OM_ComplexObservation) is intended for use where the observation event is concerned with the evaluation of multiple measurands at a specified location and time instant or duration. The result of this observation type shall refer to an entity of metatype Record (from ISO 19103).<br /></p><p><br /></p><p>ComplexSamplingMeasurement enforces the following additional constraints:<br /></p><p>- 'featureOfInterest' shall refer to an entity of type SF_SpatialSamplingFeature (from ISO 19156), or subclass thereof; and <br /></p><p>- 'procedure' shall refer to an entity of type Process (from METCE), or subclass thereof<br /></p><p><br /></p><p>The OM_ComplexObservation is used because the 'result' of this class of observations is a group of measures, provided as a Record. Again, this matches the WMO application domain wherein multiple phenomena are measured within a single 'observation event'.<br /></p><p><br /></p><p>The term ‘measurement’ is used in the name in an attempt to reduce confusion arising from the overloading of the term ‘observation’.<br /></p>

«FeatureType» SF_SpatialSamplingFeature Class |
Name: propertyValueProvider |
Name: featureOfInterest The association role 'featureOfInterest' is further constrained to refer to an entity of type 'SF_SpatialSamplingFeature' (from ISO 19156). In all cases identified thus far in meteorology, it appears useful to describe an observation, measurement or forecast with respect to the sampling regime (e.g. the Sampling Feature) and indirectly refer to the real-world entity for which the Sampling Feature is a proxy. |

«FeatureType» Process Class |
Name: generatedObservation |
Name: procedure The association role 'procedure' is further constrained to refer to an entity of type Process (from WMO METCE). This ensures that a valid concrete implementation of OM_Process is supplied. |

| Tag | Value |
| byValuePropertyType | false |
|
Details:
Values: true,false
Default: false Description: Create a property type that requires that the instance is encoded inline (applies to ISO 19136:2007 encoding rule). Always set to false in INSPIRE. |
|
| isCollection | false |
|
Details:
Values: true,false
Default: false Description: Identifies the feature type as a feature collection. |
|
| noPropertyType | false |
|
Details:
Values: true,false
Default: false Description: Surpress creation of a standard property type that supports inline or by-reference encoding (applies to ISO 19136:2007 encoding rule). Always set to false in INSPIRE. |
