Abstract:
Launched in 2005 by industrialized nations, the Group on Earth Observations (GEO) began building the Global Earth Observation System of Systems (GEOSS). Consisting of both a policy framework, and an information infrastructure, GEOSS, was intended to link and/or integrate the multitude of Earth observation systems, primarily operated by its Member Countries and Participating Organizations, so that users could more readily benefit from global information assets for a number of society’s key environmental issues. It was recognized that having ready access to observations from multiple systems was a prerequisite for both environmental decision-making, as well as economic development. From the very start, it was also recognized that the shear complexity of the Earth’s system cannot be captured by any single observation system, and that a federated, interoperable approach was necessary. While this international effort has met with much success, primarily in advancing broad, open data policies and practices, challenges remain.

In 2014 (Geneva, Switzerland) and 2015 (Mexico City, Mexico), Ministers from GEO’s Member Countries, including the European Commission, came together to assess progress made during the first decade (2005 to 2015), and approve implementation strategies and mechanisms for the second decade (2016 to 2025), respectively. The approved implementation strategies and mechanisms are intended to advance GEOSS development thereby facilitating the increased uptake of Earth observations for informed decision-making.

Clearly there are interoperability challenges that are technological in nature, and several will be discussed in this presentation. There are, however, interoperability challenges that can be better characterized as economic, governmental and/or political in nature, and these will be discussed as well.

With the emergence of the Sustainable Development Goals (SDGs), the World Conference on Disaster Risk Reduction (WCDRR), and the United Nations Framework Convention on Climate Change (UNFCCC) having occurred this year, it will be essential that the interoperability challenges described herein, regardless of their nature, be expeditiously addressed so that Earth observations can indeed inform societal decision-making.
