1 SOS in the context t of INSPIRE Alexander Kotsev S i i t Serving society Stimulating innovation Supporting legislation

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 e sciences e similar il 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 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 (2013) Comparison with other solutions Client/server solutions Availability Maturity Licensingi Mapping between INSPIRE NS regulation and SOS Mapping between INSPIRE NS regulation and SOS specifications (Bröring et. al. 2013)

5 Why not Atom and WFS? Data view Service implementation Predefined Direct access dataset download download service service WFS Х Х Atom Х Geospatial versus Observation centric perspective on data Atom - not suited for the purpose of direct access WFS - flexible enough to accommodate observation data, however: WFS focus is on features SOS focuses on observations (e.g. 1 TB of data for one feature) Flexibility in WFS may lead to very different implementations ti

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 services

9 JRC Air Quality station

10 MIG sub-group on SOS 1. Develop a project plan including deliveries in line with the specified timeframe 2. Review the proposal p for the update of the technical Guidance for INSPIRE download services to include SOS, provided by the Are3na INSPIRE/SOS study. 3. Establish a web space and maintain an issue tracker for questions, related to the establishment t of INSPIRE download services for observation data. 4. Maintain and extend the results of the Are3na INSPIRE/SOS study. 5. Propose and coordinate with the MIG update of the Technical Guidance document for INSPIRE download services. 6. Test the proposed approach with data from different Member states and different clients (web and desktop). 7. Regularly report the progress to the MIG.

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