Observations (ISO 19156, OGC/W3C SOSA)

The SOSA (Sensor, Observation, Sample, and Actuator) ontology is a realisation of the Observations, Measurements and Sampling (OMS) Conceptual model

This is set of properties defined by the SOSA ontology, assuming a "Open World Assumption" where mandatory properties may be provided by other related objects.

This BuildingBlock adds test cases from the SOSA specification to the base Observation properties model

An identifiable entity that can generate Observations pertaining to an ObservableProperty by implementing an ObservingProcedure. Device, agent (including humans), or software (simulation) involved in, or implementing, a Procedure. Sensors respond to a stimulus, e.g., a change in the environment, or input data composed from the results of prior Observations, and generate a Result. Sensors can be hosted by Platforms.

This building block defines the set of properties for an observation according to the SOSA/SSN specification. These properties may be directly included into a root element of a JSON object or used in the properties container of a GeoJSON feature.

This building block defines the set of properties for an observation Platform according to the SOSA/SSN specification. These properties may be directly included into a root element of a JSON object or used in the properties container of a GeoJSON feature.

This building block defines an ObservationCollection according to the SOSA/SSN v1.1 specification. It defines a set of logical rules regarding presence of mandatory properties anywhere within a potentially nested collection hierarchy. (implemented in SHACL, exploiting the semantic mapping to SOSA)

This building blocks defines a GeoJSON feature containing a SOSA Observation, using the properties defined in the Observation Properties schema

This building blocks defines an ObservationCollection Feature according to the SOSA/SSN v1.1 specification.
