  5. Europa Linked Observation Browser How big is the damage? • 10 people died. • € 11 billion loss. • Thousands of people needed to leave their homes. • Cultural heritage destroyed. • ...

  6. Europa Linked Observation Browser How are environmental data currently acquired?

  7. Europa Linked Observation Browser Sensor Web Enablement (SWE)

  8. Europa Linked Observation Browser Sensor Observation Service (SOS) • OGC Standard (Open Geospatial Consortium) • Enables Sensor Data Exchange • Uses the (O&M) Observation and Measurements Standard (INSPIRE compliant) • SOS will soon be INSPIRE compliant. • Dr. Arne Bröring‘s Presentation (Making The Sensor Observation Service INSPIRE Compliant), Thursday, at 14:00hr in the Room 1.

  9. Europa Linked Observation Browser Interoperability Issue O&M • Water level • Water tempeature • Water salinity • ... How to make observation data discoverable? Linked Open Data!

  10. Europa Linked Observation Browser What is Linked Open Data?

  11. Europa Linked Observation Browser The web is full of DATA!

  12. Europa Linked Observation Browser The Web Link Awesome discoverability! But just for humans :(

  13. Europa Linked Observation Browser ? The forbidden fruit Xxxxxx xxxxxx xxxxxxxx xxx xxx xxx xxx. Xxxx xxxx x xxxxx xxxxxx • What is the article about? • Who is the author? • What is inside the picture? • Where, when and by whom was the picture taken? • ...

  14. Europa Linked Observation Browser Linked Open Data “linked open data describes a method of publishing structured data so that it can be interlinked and become more useful.” Tim Berners-Lee (Inventor of the World Wide Web)

  16. Europa Linked Observation Browser Some benefits of Linked Open Data • Attaches meaning to data • Allows efficient thematic searches (e.g. person, company, city, book, etc.) • Links different kinds of datasets making the WORLD a single big repository! • Private data and public data can be mixed, enabling companies and individuals to make better decisions and generate innovations. My repository!

  17. Europa Linked Observation Browser How to make observation data discoverable in the semantic web?

  18. Europa Linked Observation Browser Europa Linked Observation Browser An overview in 3 steps…

  19. Europa Linked Observation Browser Interoperability Issue (recap) O&M • Water level • Water tempeature • Water salinity • ...

  20. Europa Linked Observation Browser Step 1 – Solving the discoverability issue. O&M Transformation • Water level • Water tempeature • Water salinity • ...

  21. Europa Linked Observation Browser Step 2 – Consuming observation measurements • List observed phenomena (e.g. water level, water temperature, etc.) • Correlate observed phenomena (e.g. Water level and Wind speed). • Project in a virtual globe where the phenomena is being measured. • Enables temporal queries . • Shows a time-series animation of the choosen phenomena.

  22. Europa Linked Observation Browser Step 3 – diving into the semantic web(Asking spatial-thematic questions) • Which cities are around the flooding area? • Which museums are around the flooding area? • Which cultural heritagesare around the flooding area? • Which of them have been destroyed and which of them are still in danger? (proximity)

  23. Europa Linked Observation Browser An Application Use Case

  24. Europa Linked Observation Browser Saving Cultural Heritages Users of the Europa Linked Observation Browser A biblical hero being rescued! (David)

  25. Europa Linked Observation Browser Video • DESCRIBE VIDEO USE CASE !!! • Explain DBPEDIA!

  26. Europa Linked Observation Browser Europa Linked Observation BrowserWrapping up... • Provides a high interoperable platform for linking observation data to the semantic web. • Enables the correlation of observation data and any other relevant data availabe in the web. • Makes observation data discoverable not only by the browser, but for the rest of the web (World). • Enable time-series animation for a better visualization of the observed phenomena. • It is totally supported by the SOS developers. • It is awesome!

  27. Europa Linked Observation Browser Future Work • Export animation in a video format. • Create a Java API with the application core functionalities • Your idea!
