GIS or Geospatial - Earth Observation

Earth observation is the gathering of information about planet Earth’s physical, chemical and biological systems via remote sensing technologies, usually involving satellites carrying imaging devices. Earth observation is used to monitor and assess the status of, and changes in, the natural and manmade environment. Space-based technologies deliver reliable and repeat-coverage datasets, which combined with research and development of appropriate methods, provide a unique means for gathering information concerning the planet. Examples include the monitoring of the state and evolution of our environment, be it land, sea or air, and the ability to rapidly assess situations during crises such as extreme weather events or during times of human conflict.
