OGC Sensor Observation Service (SOS) Standard Version 2.0 Adopted
Release Date:
25 April 2012
25 April 2012. The Open Geospatial Consortium (OGC®) membership has
adopted the OGC Sensor Observation Service (SOS) Interface Standard
Version 2.0.
Whether from in-situ sensors (e.g., water monitoring) or remote
sensors (e.g., satellite imaging), observations made from sensor systems
contribute most of the geospatial data by volume used in geospatial
systems today. The OGC® Sensor Observation Service Interface Standard
(SOS) provides an open, well-defined API for managing measured data as
well as metadata from deployed sensors. The SOS is one standard in the OGC Sensor Web Enablement (SWE) suite of standards.
SOS 2.0 includes a modular restructuring of the document, a new and
easy to use key-value-pair binding, a new SOAP binding, a redesign of
the observation offering concept, and it now relies on the common OGC
Sensor Web Enablement Service Model. SOS 2.0 is highly modular and
follows the OGC core/extension design pattern. The main SOS 2.0 document
incorporates the core as well as the transactional extension, result
handling extension, enhanced operations extension, binding extension,
and a profile for spatial filtering of observations. Further extensions
can be built upon this framework in the future.
The SOS 2.0 standard is available at:
The OGC is an international consortium of more than 435 companies,
government agencies, research organizations, and universities
participating in a consensus process to develop publicly available
geospatial standards. OGC Standards support interoperable solutions that
"geo-enable" the Web, wireless and location-based services, and
mainstream IT. OGC Standards empower technology developers to make
geospatial information and services accessible and useful with any
application that needs to be geospatially enabled. Visit the OGC website
