Earth Observations, such as satellite imagery and Lidar, are an important source of data on the state of ecosystems, but their use in practice is still limited. The European-funded H2020 project ECOPOTENTIAL aims to make EO more usable in assessing ecosystem functions and services for management of protected areas.
