Earth Observation Systems (EOS)

Devising new approaches to apply earth observation to the many challenges facing humanity with an emphasis on citizen science

Many of the challenges we face in the upcoming decades are truly global in nature - food security, climate change, natural hazards and land use change for example. In addition they are dynamic and interlinked with socioeconomic issues. Hence the EOS group is conducting research into the application of earth observation to address some of these challenges. In particular, we are exploring the enormous potential of such techniques as citizen science, and the benefits that can be derived when we combine these efforts.
