  1. Meeting on OGC Sensor Observation Service (SOS) for INSPIRE MickaelTreguer, Thomas Loubrieu Ifremer (France)

  2. Delivered content Ifremer manage marine and oceanographicdatasets • 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

  3. Delivered content

  4. 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

  5. Technologies / software used • On-going development of operational version • Oceanotronis a data server dedicated to marine in-situ observations dissemination

  6. Technologies / software used • Oceanotron focus on in-situ water column observations: • Profiles • PointSeries • Trajectories • Development of the protocolSOS (2.0) by usingopensourceproject‘constellation’ :http://www.geomatys.com/en/applications/cstlsdi.html

  7. 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)

  8. 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

  9. Technical issues (do you have recommendation?) • Common vocabularies : platform types, observed properties, organizations, units… • urn (+ urnresolver) 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/

  10. 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.
