Applying earth observation and citizen science to land cover and land use monitoring.

Many of the challenges we face in the coming decades are global, dynamic, and interlinked with socioeconomic issues - food security, climate change, natural hazards, and land use change are examples. EOCS is devising new approaches and technologies to apply earth observation to some of these challenges. Particularly, we are exploring the enormous potential of citizen science in land cover and land use monitoring. With extensive experience in app design and development, and maintaining related spatial data infrastructure, we seek the benefits of combining citizen science with more traditional approaches to working with spatial information.
