A knowledge commons for earth observation

The knowledge that will protect our planet already exists: in research papers, field reports, scientific institutions, and the lived experience of the people doing this work every day. Earth brings it together.

A knowledge commons for the global community of researchers, scientists, NGOs, and companies working in the field of earth observation to advance conservation, sustainability, and human rights, where knowledge is shared, amplified, and put to work.
