About Crowd4Sat

Crowd4Sat is an initiative from the European Space Agency to test crowd-sourcing and citizen science methodologies to utilise, process and validate observations from satellites, including in Earth observation, astronomy, GNSS and ISS based research. Two separate consortia are developing this work.


Our particular approach, led by Imperative Space, focusses predominantly on the use of 'human pattern recognition' - i.e. tapping into the powerful and unique ability of the human  brain, still unrivalled by computers, to quickly visually assess and classify images. We are partnering with Zooniverse, based at the University of Oxford, UK, a world-leading research team in this form of citizen science. Their tried and tested platform has successfully achieved millions of classifications and resulted in numerous research papers, on subjects ranging from astronomy to climate change.


We will also be looking particularly at the educational opportunities presented by citizen science. We will provide curriculum resources for each of the project strands and guidance on how citizen science can enable students to participate directly in real research and contribute to global challenges.


Commencing in late 2015, we will run a series of demonstration projects, open to all citizens and students, to test the role and impact of citizen science in a range of scientific, environmental and educational areas. These will be divided into larger scale 'Core' projects and more experimental 'Challenge' projects, and you can click on the sections below to read more about the themes we will be covering. We may incorporate other forms of crowd-sourcing into these projects, including some machine processing and gathering volunteer ground data captured with mobile phones. Our aim will be to assess how a range of citizen science techniques can help to make better use of and support the validation of satellite data, and develop novel services and tools.


We will publish more details on this website about the projects, partnerships, data and educational resources for this initiative in the autumn 2015.


Core Projects

Challenge Projects

Coming Soon

Our Core demonstration projects have pre-defined goals and associated research groups. They will make use of the full-scale Zooniverse platform and global community of citizien scientists, in astronomy and disaster relief.

The Challenge projects will provide a menu of project options based around key environ-mental and humantitarian themes. They will utilise new features of the Zooniverse platfrom, including self-build project tools.

To enable the successful running and outcomes from these demonstration projects, we are partnering with a range of NGOs and data providers. More details about this, along with educational resources, will be added here soon.
