Global Earth Observation System of Systems

The Global Earth Observation System of Systems (GEOSS) is being built[needs update] by the Group on Earth Observations (GEO) on the basis of a 10-Year Implementation Plan running from 2005 to 2015.[1] 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. GEOSS aims to produce a global public infrastructure that generates comprehensive, near-real-time environmental data, information and analyses for a wide range of users. The Secretariat Director of Geoss is Barbara Ryan.[2]

## Earth observation systems

Earth observation systems consist of instruments and models designed to measure, monitor and predict the physical, chemical and biological aspects of the Earth system. Buoys floating in the oceans monitor temperature and salinity; meteorological stations and balloons record air quality and rainwater trends; sonar and radar systems estimate fish and bird populations; seismic and Global Positioning System (GPS) stations record movements in the Earth’s crust and interior; some 60-plus high-tech environmental satellites scan the planet from space; powerful computerized models generate simulations and forecasts; and early warning systems issue alerts to vulnerable populations.

These various systems have typically operated in isolation from one another. In recent years, however, sophisticated new technologies for gathering vast quantities of near-real-time and high-resolution Earth observation data have become operational. At the same time, improved forecasting models and decision-support tools are increasingly allowing decision makers and other users of Earth observations to fully exploit this widening stream of information.

With investments in Earth observations now reaching a critical mass, it has become possible to link diverse observing systems together to paint a full picture of the Earth’s condition. Because the costs and logistics of expanding Earth observations are daunting for any single nation, linking systems together through international cooperation also offers cost savings.

## Implementation

As a networked system, GEOSS is owned by all of the GEO Members and Participating Organizations. Partners maintain full control of the components and activities that they contribute to the system of systems.[3] Implementation is being pursued through a Work Plan consisting of over 70 tasks. Each task supports one of the nine societal-benefit or four transverse areas and is carried out by interested Members and Participating Organizations. Governments and organizations have also advanced GEOSS by contributing a variety of “Early Achievements”; these “First 100 Steps to GEOSS” were presented to the 2007 Cape Town Ministerial Summit.

Interlinking observation systems requires common standards for architecture and data sharing. The architecture of an Earth observation system refers to the way in which its components are designed so that they function as a whole. Each GEOSS component must be included in the GEOSS registry and configured so that it can communicate with the other participating systems. In addition, each contributor to GEOSS must subscribe to the GEO data-sharing principles, which aim to ensure the full and open exchange of data, metadata and products. These issues are fundamental to the successful operation of GEOSS.[4][5][6][7]

GEOSS will disseminate information and analyses directly to users. GEO is developing the GEOPortal as a single Internet gateway to the data produced by GEOSS. The purpose of GEOPortal is to make it easier to integrate diverse data sets, identify relevant data and portals of contributing systems, and access models and other decision-support tools. For users without good access to high-speed internet, GEO has established GEONETCast, a system of four communications satellites that transmit data to low-cost receiving stations maintained by the users.[8]

At present, GEONETCast seems still in its infancy, yet some tools have already been worked out. The GEONETCast toolbox has been made available and contains tools to access some radar altimetry, vegetation, satellite prediction and maritime information.[9] Other useful information available through GEONETCast is vegetation and desert locust information provided under the DevCoCast project, which is a subproject of GEONETCast.[10][11]

## User groups

The growing demand for Earth observation data and information is the driving force behind GEOSS. The GEOSS Implementation Plan identifies nine distinct groups of users and uses, which it calls “Societal Benefit Areas”. The nine areas are disasters, health, energy, climate, water, weather, ecosystems, agriculture and biodiversity. Current and potential users include decision makers in the public and private sectors, resource managers, planners, emergency responders and scientists.[12][13][14][15]

## Related initiatives

GEOSS can be characterized as a contribution towards the establishment of a spatial data infrastructure. It is one of three related initiatives that are the subject of the GIGAS (GEOSS, INSPIRE and GMES an Action in Support) harmonization project under the auspices of the EU 7th Framework Programme.[16]
