Group on Earth Observations (GEO) Story Map
Humankind has always relied on clues from the environment to survive, to plant seeds when the rains come, to harness wind power to grind grain.
It is only in the last few decades that we have the tools to observe the entire planet. Technology and scientific collaboration allow us to measure the full extent of our oceans and land—to discover it is changing, fast.
Satellites map changes in land cover, such as deforestation or urban expansion. Atmospheric, land- and ocean-based instruments reveal we live on a hotter planet, with more extreme events such as droughts and floods and increasing pressure on natural resources.
By combing data over time, or by comparing data from different sources, intelligent decisions can be made about human development, wildlife protection and the effects of climate change. The huge monitoring capacity requires strong systems.
International cooperation through the Group on Earth Observations (GEO) is building the Global Earth Observation System of Systems (GEOSS) to discover and access the data required to draw conclusions and make predictions.
