The OGC Sensor Observation Service aggregates readings from live, in-situ and remote sensors. The service provides an interface to make sensors and sensor data archives accessible via an interoperable web based interface.
The SOS 2.0 specification was adopted in 2012 and four extension are defined within the specification: Core, Enhanced, Transactional, and Result Handling.
For more information about the SOS 2.0 specification, see the official OGC SOS 2.0 tutorial
The SOS 1.0.0 specification was adopted in 2008 and four profiles are defined within the specification: core, transactional, enhanced, and entire.
The 52°North SOS was used as reference for the SOS 1.0.0 compliance tests during the OWS-5 testbed. After the SOS has been published as official OGC implementation specification in spring of 2008, this new implementation was implemented with the 52°North SOS version 3.1.0.
The latest implementation of the 52°North SOS (version 4.x) was started in 2012 and was used as reference for the SOS 2.0 compliance tests during the OWS-9 testbed. This version is recommended to all users who want to start new sensor web projects and deployments.
The 52°North SOS 4.x is a complete reimplementation of 52°North SOS to support the requirements of the SOS 2.0 specification.
Here is a short list of the most important features:
This SOS version implements all SOS 2.0 extensions comprising the following operations:
Furthermore, the following SOS 1.0.0 operations are supported:
Other features which are supported by 52°North SOS 4.x
There are multiple clients for the SOS developed by 52°North. Based upon the OX-Framework both thin clients and thick clients can be developed for your use cases. Also other web services such as the OGC Web Processing Services can access the provided data of the 52°North SOS to generate new data, compute simulations or other highler level data products. The 52°North geostatistics community developed the R package sos4R to download data from SOS servers directly into the R software environment for statistical computing and allow manifold analyses and powerful visualization.
Besides the different clients developed within 52°North, there are other parties who develop interesting SOS clients. An example is the browser-based client of the Tasmanian hydrological sensor web implemented by CSIRO. Have a look and try it out yourself: here. The sensor data which can be displayed by this client is provided by a 52°North SOS instance.
Besides several demo videos of our different SOS client applications we are maintaining running demo instances which you can use for testing or hands-on experience.

|The enhancements to make the 52°North SOS an INSPIRE compliant Download Service were funded by the JRC under the ISA Programme’s Action 1.17: A Reusable INSPIRE Reference Platform (ARE3NA).|
|The IOOS project with the mission:
Lead the integration of ocean, coastal, and Great Lakes observing capabilities, in collaboration with Federal and non-Federal partners, to maximize access to data and generation of information products, inform decision making, and promote economic, environmental, and social benefits to our Nation and the world.
|The Wupperverband for water, humans and the environment (Germany)|
|The Belgian Interregional Environment Agency (IRCEL - CELINE) is primarily active with the domain of air quality (modelling, forecasts, informing the public on the state of their air quality, e-reporting to the EU under the air quality directives, participating in scientific research on air quality, etc.). IRCEL - CELINE is a permanent cooperation between three regional environment agencies: Agence wallonne de l'Air et du Climat (AWAC), Bruxelles Environnement - Leefmilieu Brussel and Vlaamse Milieumaatschappij (VMM).|

|The SMART Project, funded by the Ministry of Business, Innovation and Employment (07/2011 – 06/2017):
Experts in the Smart Project will develop, apply, and validate pioneering new techniques for understanding New Zealand’s groundwater resources. Satellite and airborne remote sensing techniques and Sensor Observation Services including seismic signals from earthquakes are used for rapid and costeffective characterisation and mapping of New Zealand’s aquifer systems. Together with a stakeholder network the research team will use new methods to overcome the current time- and resourceconsuming challenges of in-time data acquisition. Special spatial skills in hydrogeology, geology, satellite remote sensing, geophysics, seismology, uncertainty mathematics and spatial information technology will be developed to assist with improvement of New Zealand’s freshwater management.
