The Sensor Observation Service (SOS) 2.0 is an approved Open Geospatial Consortium standard. The standard defines a common web service interface for the retrieval of real time or archived data produced by all kinds of sensors like mobile or stationary as well as in-situ or remote sensors.

The sensor data are either observations or metadata of the sensors containing information like calibration information, positions, etc.  Observations are returned encoded as O&M Observations, while  information about sensors are returned encoded in SensorML. Used in conjunction with these OGC standards and other OGC specifications, the SOS provides a broad range of interoperable capability for  discovering, binding to and interrogating individual sensors, sensor platforms, or networked constellations of sensors in real-time, archived or simulated environments.

This page aims to provide an overview on the data encodings in which data is provided by SOS and on the operations provided by a SOS inteface. 

 To learn about the data models and encodings used by the SOS, go to the following sub-pages:

The following sub-pages describe the operations of the SOS and its functionality:
