About

• The Copernicus programme is part of the European Union’s space programme and aims to monitor the Earth and its environment by collecting data from a set of satellites known as the Sentinels. 
• It was launched in 1998 and earlier called Global Monitoring for Environmental Security (GMES).
• Currently, it is implemented by the European Commission (EC) with support from the European Space Agency and the European Environment Agency (EEA).
• It gets data from contributing missions (existing commercial and public satellites) and in situ or non-space sources such as ground stations.
• The data are processed and analyzed to generate value-added information, which can be used for a wide range of applications in many areas. 
  • These include land management, the marine environment, the atmosphere, emergency response, security, and climate change.

What is Copernicus Emergency Management Service (EMS) ?

• The Copernicus EMS provides geo-spatial information derived from satellite remote sensing and in situ data sources to help manage natural disasters, man-made emergencies, and humanitarian crises.
• It has been in operation since 2012.
