This open session will serve a a regular meeting of this CoP as well as a preparation for a more focused activities that could take place during the weekend (see above) with the other CoPs (e.g. writting a draft of the Engineering report of the IE)


  • Attendants: Andy Cobley, Bente Lilja Bye, Jessica Wardlaw, Simon Jirka, Friederike Klan, Joan Masó, Ester Prat, Uta Wehn, Marie-Francoise Voidrot, 3 people from MONOCLE project. Remotely: Orestis Speyer, Andreas Matheus, Lucy Bastin.

  • Introduction from Joan Masó:
    • Citizen Science and its social and technical innovation aspects.
    • WeObserve project and its 4 Communities of Practices: engage, impact, interoperability and SDGs.
    • GEO, the OGC and the Citizen Science Interoperability Experiment
    • Interop-CoP: Previous meetings and 4 topics addressed: vocabularies, single sign-on, data sharing and data quality. Initiators and supporters of the Interoperability Experiment.
    • Earth Challenge 2020: goal of engaging millions of global citizens in collecting one billion data points
  • Advances in data sharing:
    • We are following legacy of the project CobWeb, which introduced that Sensor Web Enablement (SWE) was useful for Citizen Science (CS). It implies a data model and a SOS (Sensor Observation Service) client. We have started with O&M (Observations & Measures) standard from OGC. Friederike Klan asks for the difference with sensor thing. It comes from the internet of things. They are very similar but the “thing” is what cannot be modelled with O&M. It’s a REST interface and it has its own data model. There are several ways of expressing the standard. It is possible to send a time series as a single value. In a closed environment you don’t need to share and replicate all the info, but when sharing data.
    • Simon Jirka introduces HackAir platform, which collects several sources of air quality data monitoring. It is a REST and JSON service, it has its own data model, is not following OGC. It set up an SOS service collecting API HackAir and published as an SOS server. Stations are accessible and data can be consulted. The idea is to connect other SOS data sources. Access the platform
    • Andy Cobley presents an SOS service developed within the GROW project (download presentation). The server shows GROW sensors and air pollutant sensors. It is built using Power BI (Business Intelligence Microsoft). GROW SOS + Hackair SOS through Python transformed in tabular database and then showed as iframe. GROW reads XML and HackAir.
    • Joan Masó shows a JavaScript client capable to read SOS directly. XML transformation is done in the client side. It reads GetFeatureofInterest and get an XML file. It shows HackAir sensors and also Meet Mee Mechelen observations (a Ground Truth 2.0 observatory) over Open Street Map. It uses HTML5 canvas and is extremely fast to represent on the screen. He comments that the 52N server does not accept optional parameters, it rejects the observation instead of ignore the parameters. Also a client can not read data from 2 servers, only show it, due to a CORS restriction in the headers. The hack is to use one of the servers to ask data from the other server and then send both through the previous one.
    • Friederike Klan presents OpenData (download presentation). It contains a form to drag and drop data. They have an app through where people collect data. They use OpenData form (is open). If not all data required is filled you get a warning. They use ontologies that are included in the form. From data + templates using an aggregator and sent to OpenData Kit (ODK). Useful to give citizens tools which are compliant with standards. Bente Lilja Bye thinks that requiring citizens to fill a form can be an obstacle to get spontaneous observations.
  • Advances in data quality:
    • Joan Masó starts presenting advances in data quality. According to a paper, 3 approaches to data quality exist: producer quality model, consumer quality model and stakeholders quality model. They use quality controls implemented as a WPS service. Joan Masó implemented the qcs in the client instead and combined it with a user feedback and using the QualityML vocabulary. User performance could be also included. Bente Lilja Bye mentions that a biologist association has something with authorization. They collect this kind of data. We can contact them. They also use a gaming environment for collecting statistics on user performance.
    • Joan Masó presents Land Use Mapper (LUM) initiatives over OSM (Open Street Map). He developed a web based system to compare 2 layers and get a confusion matrix on the fly. Comparison is tricky due to the different levels used in the legends. He used an equation in JavaScript to reduce all values to the same level.
  • Other initiatives:
    • A hackathon to develop OGC API specifications is organized on June 20-21 in London. OGC was having advantage 10 years ago with XML, but now is being outdated. They are trying to use the hackathon approach to recover. Open API allows for creating a series of URL that describe ?. It uses YAML. This can impact the sensor standard. It could a matter for our next Interoperability Experiment.
    • Andy Cobley mentions that WeObserve will be running an Open Data Challenge. It is aimed at SMEs and startups using data from existing observatories. Start end of 2019. 10.000 euros reward. Now there is a call for nomination of datasets. Objective is demonstrate the use of data. Lucy Bastin offers some datasets related to protected areas: The link for the download of the full DOPA dataset is here: (gives the most complete dataset which can be taken down to the level of individual protected areas). Also some other data that might be of interest here:
    • Uta Wehn introduces the CSEOL call: an initiative to bring ideas to validate citizen science data into funded projects. Application is now open. The Nairobi Hackathon is open data and source INSPIRE hackathon. About interoperability in CS. Called the Satellite INSPIRE hackathon. It's not a competition but a community building. Pre-defined 9 teams with mentors. Uta Wehn is the mentor of the CS theme. CSEOL is ?. Results will be presented in a workshop in East Africa with people from all over Africa. Actually they have 10-30 registrants for webinars, some of them from Africa. Open Land Use for Africa is another theme. Still possible to participate through Bente Lilja Bye.
  • Any other business
    • Some guy from a non-profit organization trying to involve citizens in air quality remote sensing monitoring.
    • Integrate all Flandes in JM browser.
    • Jessica Wardlaw is Interested in SDGs but also in Interoperability. She is involved in a project about modern slavery.

  • New topics for next IE:
    • Steffen Fritz wants to connect to EU.
    • Try to merge WMO data with other sources of meteo.
    • OGC OpenAPI
  • Try to involve again ICCS and Scent into the IE
  • Leuven meeting to present the Engineering Report
  • Structure of the document Engineering Report drafted and shared among Joan Masó and Andy Cobley to start contributing.
