Environmental indicators, modelling and outlooks

Earth observation for decision-making


Earth observation from satellites, aircrafts and drones, in-situ measurements or ground-based monitoring stations, can provide a unique and timely source of data that is commensurable across countries, regions and cities.

It can help harmonise international reporting on natural resources, ecosystems and environmental sinks. It can be combined with other geo-referenced socio-demographic, economic and public administration data to make indicators and analysis more relevant and targeted.

Earth observation is not new, but it is only recently that investments in satellite capabilities, open and free access to data and tools, and advances in algorithms and data processing have started to enable the widespread use of this information at scale, and beyond the specialised scientific community. These developments offer opportunities for improving the range and robustness of environmental data and indicators.

Earth observations and other geospatial data are used to develop several OECD indicators, particularly on land cover changes, exposure to air pollution and on protected areas.
