Why is it relevant?

Applying open data policies to Citizen Observatories increases the impact of the data by preventing ‘data silos’ (storage of different data in different places) and thereby duplication of efforts. Adopting data standards lowers the technical barriers and opens new possibilities for exploiting the data by combining them with other themes and across locations.

How can this be achieved?

There are a range of tools and guidelines that can help your Citizen Observatory apply open data policies and data standards.

In the European Union, public sector organisations must comply with the Open Data and Public Sector Information Directive (ODPSI) that came into force in July 2019. The Directive focuses on the economic aspects of the re-use of information and introduces the concept of high-value data sets. Earth observation and environment, which are the focus of many Citizen Observatories, are second in the thematic categories of high-value data sets. The Aarhus Convention (by the United Nations Economic Commission for Europe) focuses on access to environmental information by citizens. These policies shape the context in which your Citizen Observatory has to function and with which it must  comply.

The Global Earth Observation System of Systems (GEOSS) offers a single access point via its geoportal, connecting users to various environmental monitoring systems around the world while promoting the use of common technical standards to support their use. Similarly, the European Open Science Cloud (EOSC) provides a virtual environment with open and seamless services for the storage, management, analysis and re-use of research data. 

Integrating available resources with mechanisms like GEOSS and EOSC, and leveraging their data management and FAIR principles, gives us a simple way to deal with open data obligations and to access research data across different disciplines while also promoting the use of open solutions and common standards for data sharing.

GEOSS was developed by the Group on Earth Observation (GEO). GEO’s three Data Sharing Principles state that:

  • there will be full and open exchange of data, metadata and products shared within GEOSS, recognising relevant international instruments and national policies and legislation;  
  • all shared data, metadata and products will be made available with a minimum time delay and at minimum cost; and 
  • all shared data, metadata and products are encouraged to be made available free of charge or at no more than reproduction cost for research and education. 

The Open Data Institute (ODI) suggests that the general context for open data policy should first be developed, in order to define its scope. This should include:

  • a definition of open data – why open data is important to the project and the reasons that a policy is needed;
  • general principles to guide the release and reuse of open data;
  • the types of data collected and whether they are covered by the policy; and
  • references to relevant legislation, policies or other guidance that also apply to the management and sharing of information with third parties.

ODI has created a checklist of further policy elements to aid the development of open data policy:

  • Data licensing and reuse rights
  • Identifying and prioritising data for release
  • Privacy considerations
  • Data publishing standards
  • Engaging with re-users
  • Approach to consuming data
  • Concrete commitments
  • Policy transparency

ODI has also developed the Open Data Maturity Model, a tool for assessing the level at which an organisation utilises and shares open data. You can use this model, and also map your data practices, via the Open Data Pathway.

A JRC report from 2018 titled “An inventory of citizen science activities for environmental policies” identified 503 projects in the environment field, and Citizen Observatories are becoming more and more prevalent (more about the history of Citizen Observatories here). As the number of Citizen Observatories and citizen science projects increase, the need for standard practices has become even more critical. The Open Geospatial Consortium (OGC) and the WeObserve project are working on developing best practices on how to apply existing OGC standards for citizen science (see box below). 

In parallel, several efforts have been undertaken by administrations and cartographic (mapping) agencies to set and use standard formats and services. This has resulted in the proliferation of Spatial Data Infrastructures (e.g. INSPIRE). The smart cities phenomenon is also possible thanks to the adoption of standard sensor and communication protocols. Citizen science initiatives each have their own characteristics (e.g. a myriad of data authors and a constant conversation and revision of the observations), but they also share many aspects, such as the geospatial nature of environmental measurements and the use of the same variables and observation types as other approaches (e.g ‘smart cities’ sensors).

Citizen Observatories can adopt and test current standards in their own domains. When they do not fit their purpose, they should be extended and adapted based on discussion towards finding consensus. The set of standards enabling sensor webs are a good starting point, as they focus on individual observations from a well-defined set of variables that are aggregated into data streams.

There is also a need for formal representation of Citizen Observatories as a whole as a key tool in enabling the discovery of data sets, projects and campaigns. It should facilitate knowledge sharing and contribute to current standardisation efforts. The Public Participation in Scientific Research (PPSR) Common Conceptual Model is a starting point in this direction.

Lessons learned from the Ground Truth 2.0 project and the Citizen Science Interoperability experiment.

During the Citizen Science Interoperability experiment, the following data servers providing support to the OGC Sensor Observation System (SOS) standard were deployed: MiraMon SOS server, Grow SOS, DLR istSOS SOS, and 52north SOS. Three clients were also produced: MiraMon SOS browser, Grow SOS data viewer, and 52north Helgoland. The group demonstrated interoperability by connecting the SOS clients to the SOS services and showing the data on clients, sometimes mixing data from different services and datasets in a single view. 

The illustration presents air quality data from the HachAir project in the DLR premises, together with Ground Truth 2.0 data that uses the MiraMon SOS service.
