  1. SOS in the context of INSPIRE Alexander Kotsev

  2. Context • The number of devices connected to the Internet exceeded that of people in 2008 and • Expected to reach 50 billion in 2020 (Swan, 2012) • Many of those are sensors which may be organized into sensing networks • Environmental wireless sensor networks in the IoT have a new kind of scope which can be applied to a wide range of uses (Martinez, 2004) • This is creating a revolution in all environmental sciences similar to the one generated by the use of satellite remote sensing in the 1970s (Hart et. al. 2006).

  3. INSPIRE and observation data from sensors • INSPIRE as Framework Directive is focused on the ’spatial’ • However • Guidelines for the use of Observations & Measurements and Sensor Web Enablement-related standards in INSPIRE Annex II and III data specification development • Created in response to the necessity to provide observation data in Annex II and Annex III • http://inspire.ec.europa.eu/documents/Data_Specifications/D2.9_O&M_Guidelines_v2.0rc3.pdf • SOS is seen as one of the possible candidates for the extension of TG for INSPIRE Download services (v. 3.0)

  4. Study on SOS in the context of INSPIRE • Comparison with other solutions • Mapping between INSPIRE NS regulation and SOS specifications (Bröring et. al. 2012) • Availability of client/server solutions

  5. Why not Atom and WFS? • Data view • Geospatial versus Observation centric perspective on data • Atom – not suited for the purpose of direct access • WFS is flexible enough to accommodate observation data • However: • WFS focus is on features • Flexibility may lead to very different implementations • SOS focuses on observations (e.g. 1 TB of data for one feature)

  6. Availability of solutions – server implementations

  7. Availability of solutions – clients

  8. TG update and Open Source INSPIRE/SOS Implementation (Are3na) • Bundle of: • Open Source Software • Proposal for an update of the Technical Guidance document for INSPIRE Download servcies http://inspireaq.jrc.ec.europa.eu/52n-inspire-sos

  9. JRC Air Quality station http://inspireaq.jrc.ec.europa.eu/52n-inspire-sos/sos/kvp?service=SOS&request=GetCapabilities

  10. Possible ways ahead • Sensors with onboard service capabilities • RaspberryPI • Arduino shield (JRC Air and Climate unit) • Study of other INSPIRE download service ‘candidates’ • Web Coverage Service (WCS) • Table Joining Service (TJS)
