OGC Best Practice for Sensor Web Enablement: Provision of Observations through an PGC Sensor Observation Service (SOS). Version 1.0.

Abstract

The OGC Sensor Web Enablement (SWE) architecture (OGC, 2008c) defines a conceptual approach to build a Spatial Data Infrastructure (SDI) for sensor data. This architecture provides the conceptual foundation and standard framework of the work presented in this document. In addition to the OGC SWE architecture, the present recommendations and tools rely upon the architectural work that has been carried out in a series of European research projects and submitted to OGC as best-practices work follows: -- Reference Model of the ORCHESTRA Architecture (RM-OA) (OGC, 2007c), accepted as OGC best-practices paper in 2007, that instantiated and tailored the OGC Reference Model for the domain of environmental risk management following the ISO Reference Model for Open Distributed Processing (RM-ODP) (ISO/IEC 10746-1:1998), and -- the Sensor Service Architecture (SensorSA) (OGC, 2009d), accepted as OGC discussion paper in 2009, that extended the RM-OA towards a sensor-based environment following the OGC SWE architecture. The EO2HEAVEN architectural work has continued this architectural specification line in its multi-part specification of a Spatial Information Infrastructure (SII) (EO2HEAVEN, 2011a) integrating both in-situ and space-borne EO sensors. The present document is an excerpt of the EO2HEAVEN SII focusing on the advanced SWE concepts (EO2HEAVEN, 2011b) for the provision of observation in SOS instances.
