The Global Earth Observation System of Systems (GEOSS) will provide decision-support tools to a wide variety of users. It will proactively link together existing and planned observing systems around the world and support the development of new systems where gaps currently exist.
It is being built (in 2012) by the Group on Earth Observations (GEO), on the basis of a 10-Year Implementation Plan running from 2005 to 2015.
GEOSS seeks to connect the producers of environmental data and decision-support tools with the end users of these products, with the aim of enhancing the relevance of Earth observations to global issues. The result is to be a global public infrastructure that generates comprehensive, near-real-time environmental data, information and analyses for a wide range of users.
