COBWEB Summit at the OGC TC Dublin, 2016

2. Agenda Time Who Slot Notes Tues 21st June, 2016 1245-1300 Arrival 1300-1330 Chris Welcome, context 1330-1400 MichaelK/ AndreasM German demonstrator 1400-1445 Barnard/UCD Semantics the UCD way 1445-1515 Coffee 1515-1600 Ingo/Rob Modelling progress 1600-1630 AndreasM Privacy and security 1630-1700 Mike/UNOTT Quality Assurance

3. Objectives • Inform participants of the work undertaken under COBWEB • Stimulate discussion around the more problematic and challenging areas • Identify requirements for future work in respect of interoperability and standardisation • Help me distill some takeaway lessons from COBWEB for the TC

4. Introduction to COBWEB • Research Project: Funded (EUR6.5M) under the European Commission’s Framework Programme 7 • SME Targeted Collaborative project • Required to work within GEOSS framework • Started Nov 2012, ends Oct 31st 2016 (4 years)

5. Big Picture #1 • Explosion in availability of smartphones and tablets equals great potential for “citizens as sensors” • How to make the data gathered usable and reusable? • What quality measures are needed? • How to reduce uncertainty? • How can crowdsourced environmental data aid decision making? • How can our crowdsourced data be conflated with reference data and be deployed in standards based Spatial Data Infrastructures?

6. Big Picture #2 • COBWEB set out to research and develop a “generic crowdsourcing infrastructure platform” • toolkit which can be downloaded and used in multiple scenarios • Use and reuse potential of these data (cit sci) is significant but currently compromised by a lack of interoperability • Large volumes of data are being created but exist in silos • Useable standards either don’t exist, are neglected, poorly understood or tooling is unavailable

7. Project Partners

8. UNESCO World Network of Biosphere Reserves Sites of excellence to foster harmonious integration of people and nature for sustainable development through participation, knowledge sharing, poverty reduction and human well-being improvements, cultural values and society's ability to cope with change, thus contributing to the Millennium Development Goals

9. COBWEB Biosphere Reserves Biosffer Dyfi Biosphere Mount Olympus Gorge of Samaria Wadden See & Hallig islands

10. COBWEB is not a collection of Apps… A number of demonstrator mobile phone applications – Exactly what, deliberately left open and subject to discussion with community 3 pilot case study areas: 1. Validating earth observation products 2. Biological monitoring 3. Flooding

11. Co-design

12. COBWEB Framework

13. Technology Readiness Levels (TRL) TRL Definition 1 basic principles observed 2 technology concept formulated 3 experimental proof of concept 4 technology validated in lab 5 technology validated in relevant environment (industrially relevant environment in the case of key enabling technologies) 6 technology demonstrated in relevant environment (industrially relevant environment in the case of key enabling technologies) 7 system prototype demonstration in operational environment 8 system complete and qualified 9 actual system proven in operational environment (competitive manufacturing in the case of key enabling technologies; or in space)

14. Project characteristics Mainly medium to high TRLs High TRLs By definition, lower TRLs 1. Commission wants production strength outputs that contribute to GEOSS development 2. An “SME Targeted Collaborative” project • 30% EU contribution to SMEs 3. Develop 'citizens' observatories’ • Mobilise citizens • Emphasised during Grant Negotiation • “Co-design” fund established 4. A research project doing innovative work • Crowdsourced environmental data to aid decision making High TRLs

15. Key components at different TRL’s • QA workflow editor • QA WPS/services • Conflation • Sensor networks • GeoNetwork/Portal • Middleware • Authoring tool/Survey designer • Apps • User management and privacy • Access control • Authentication

16. View COBWEB Portal

18. The COBWEB version of GeoNetwork • Open source implementation of the OGC Catalogue Services for the Web • Input and storage schemas: – ISO19139, ISO199115-1 • Alternative output schemas available: – Dublin core – SensorML – DCAT – PPSR_CORE • Supports registration of ‘surveys’ or ‘citizen science projects’

19. FieldtripOpen

20. FieldtripOpen - Customise your own app for your survey

23. Citizen captures data on their phone

25. Classifying quality: Seven pillars Pillar Example Test Notes Pillar 1 – Location Based services Assessment of spatial accuracy – estimate from a mobile device and number of satellites Tests often carried out on the mobile device Pillar 2 – Cleaning Removal of junk data via an attribute text check Very lightweight, can flag or remove malicious entries Pillar 3 – Automatic validation Analysis whether an image is blurry Higher level testing, often used to assess ranges Pillar 4 – Comparison with authoritative data Use of a set of boundary polygons to check whether an observation is in or out Wide variety of tests that involve comparison with what it known Pillar 5 – Model based validation Running a flood model Can be complex, and may also include question based modeling Pillar 6 – Big/Linked data Querying Twitter via a hashtag for similar phenomena Tapping into large databases such as sensor records and social media Pillar 7 – Semantic harmonisation Rationalisation of entries via an ontology Attempts to recognise multiple entries of the same observation

26. Quality process web editor

28. Conflation • Combination of spatial data from multiple sources to produce a combined view that contains the most valuable data from the inputs • Used in Quality Assurance • Used for data enrichment, eg, from sensors • OGC Web Processing Service interface used

29. SWE4CS Publishing Data

30. SWE4CS – introduces semantics

31. SWE4CS – Why bother? • If a significant amount of Cit Sci data can be published to this standard • It becomes more useful; its immediately understood by people who understand the standard • The same tooling can be used and reused • Integration costs decrease

32. Sustainability #1 • Intending to open source as many of the COBWEB components as possible • FieldtripOpen into OSGeo one option and looking at the incubation process • SME’s leading this aspect of COBWEB

33. Sustainability #2 • Creation of a Citizen Science DWG would be / will be a significant output – as long as has community support • Reliant upon new projects picking up on outputs, eg, followon citizen observatory’s • Would like to, eg, via a hackathon, make benefits demonstrable and broadcast, but – SWE4CS currently a moving target – can we conclude with something like a v1 in association with the Best Practice paper in Sept 2016?
