Meeting on OGC Sensor Observation Service (SOS) for INSPIRE
Mickael Treguer, Thomas LoubrieuIfremer (France)
Delivered content
Ifremer manage marine and oceanographic datasets
Profiles: CTD, profiling floats (ARGO) PointSeries: moorings, including moorings with different
vertical levels Trajectories: thermo-salinomers, gliders
Scanning radar: waves observation with Doppler Swath: sea bottom observations with multi-beam echo
sounder, satellite observation Grid: analysis, climatologies, forecasts Grid series: analysis, climatologies Section: Acoustic Doppler Current Profiler, geoseismic
profiles
Delivered content
Technologies / software used
• In 2008 development of a prototype on marine time series with O&M resultsConnection of SOS (constellation project) to one of our thematic database
• experiences with 52°north deployment
Technologies / software used• On-going development of operational
version• Oceanotron is a data server dedicated
to marine in-situ observations dissemination
Technologies / software used
• Oceanotron focus on in-situ water column observations: Profiles PointSeries Trajectories
• Development of the protocol SOS (2.0) by using opensource project ‘constellation’ :http://www.geomatys.com/en/applications/cstlsdi.html
Other download services available
• ‘Usual’ GIS format: WFS (Mapserver/QGIS-Server)
– example : seabed habitats WCS (Mapserver/QGIS-Server)
– example : scan, orthophoto… WCS / Opendap (Thredds)
– example : analysis, climatologies, forecasts
• In-situ data observation are available as prepared dataset under ftp dedicated web interface (no services)
Why an INSPIRE/SOS?
• Need: Subseting of in-situ dataset Advanced viewing services (need data to plot/graph) Download services
– mechanism are wanted to manage big volumes– asynchronous mechanism
• SOS interface has well-defined temporal, spatial, and thematic filters for near realtime environmental data
Technical issues (do you have recommendation?)
• Common vocabularies : platform types, observed properties, organizations, units …
• urn (+ urn resolver) vs url ?
• The NERC Vocabulary Server (NVS) has been used to publish controlled vocabularies of terms relevant to the marine environmental sciences domainhttp://vocab.nerc.ac.uk/
Additional information (other project)
• Eurofleets : Pilot experiences to apply SWE technologies on-board. 'Real-time' links from sensors to data center (on-shore) : this means transactional functions for :
Sensor descriptions (SensorML) : events,history,calibration...
Sensor observations (O&M). Data models adapted to the marine observation data such as water column vertical profiles, time series, and vessel underway data.
