Introduction to COBWEB
• Research Project: Funded 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)• Why?
– GPS enabled, internet connected mobile devices now ubiquitous
– Lots of potential, eg, can citizen sourced environmental data be useful for decision making?
Citizen Observatory Web
• Generic crowdsourcing infrastructure– A toolkit which can be downloaded and used
in multiple scenarios• Data which supports policy• Address data quality issues• Open standards
Project Partners
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

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 products2. Biological monitoring3. Flooding

COBWEB Framework
Technology Readiness Levels (TRL)
TRL Definition1 basic principles observed2 technology concept formulated3 experimental proof of concept4 technology validated in lab5 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 environment8 system complete and qualified9 actual system proven in operational environment (competitive
manufacturing in the case of key enabling technologies; or in space)
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

COBWEB Framework
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’
• ACTION: CH to put group in touch with GeoCat

COBWEB Framework
Classifying quality: Seven pillarsPillar Example Test NotesPillar 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
Quality process web editor
COBWEB Framework
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
SWE4CS
PublishingData
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
Sustainability
• Intending to open source as many of the COBWEB components as possible
• OSGeo one option and looking at the incubation process
• SME’s leading this aspect of COBWEB
Synchronising #1 – ‘Hackathon’ @ ECSA Berlin May
• COBWEB offers to fund• Line up a variety of Cit Sci project developers
who have access to data• Provide materials and assistance to show how
transformation to SWE4CS can be done• Use to show how easy it is and the benefits that
come with interoperability
Synchronising #2 – OGC-ICA-AGILE workshop June
• Association GI Laboratories Europe (AGILE) pre-conference workshop 14th June
• The Role of Geospatial Standards for Sustainable Development
• Emphasis on the use of these standards for leveraging volunteered geographic information and enabling community observatories
• Debate: 'Are OGC and related standards fit for purpose in a fast changing technological society?‘
• Identify major research questions for maximising the value of open geospatial interoperability standards in support of the Sustainable Development Goals
Synchronising #3 – Activity at Dublin TC in June
• OGC Technical Committee meeting 20-24 June• Paid for by COBWEB• Will have an OGC Best Practice paper ready for
publication:– SWE4CS– Metadata profile for Citizen Science
• How can we make best use of this week?
