52°North
52°North is an open initiative that advances the development of cutting edge open source geospatial software. The initial focii of the open source technology development are Sensor Web Enablement (SWE) , Web Security and Digital Rights Management (DRM) . Other streams of work will open up according to community direction.
They host a collection of Java based web services implementations. Their products are published solely under the GNU General Public License (GPL) , but are also available – via a dual licensing model – to commercial users.
As an example, the 52N Sensor Observation Service enables interoperable, web-based access to sensors and real-time geosensor data. This product implements the current OGC Sensor Observation Service draft specification to access sensor information (SensorML) and sensor observations (O&M).
The 52N SOS allows specificatzion-conform provision of georeferenced measurement data. As a result, it is easily integrated in geodata-infrastructures and geoservice-infrastructures. In situ sensors (e.g. water gages), as well as remote sensing sensors can be used for data collection.
