The implementation of the INSPIRE Directive in Europe and similar efforts around the globe to develop spatial data infrastructures and global systems of systems have been focusing largely on the adoption of agreed technologies, standards, and specifications to meet the (systems) interoperability challenge. Addressing the key scientific challenges of humanity in the 21st century requires however a much increased inter-disciplinary effort, which in turn makes more complex demands on the type of systems and arrangements needed to support it. This paper analyses the challenges for inter-disciplinary interoperability using the experience of the EuroGEOSS research project. It argues that inter-disciplinarity requires mutual understanding of requirements, methods, theoretical underpinning and tacit knowledge, and this in turn demands for a flexible approach to interoperability based on mediation, brokering and semantics-aware, cross-thematic functionalities. The paper demonstrates the implications of adopting this approach and charts the trajectory for the evolution of current spatial data infrastructures.

Geos2011 - Lorenzino Vaccari - Keynote speech

  1. 1. Max Craglia(1), Stefano Nativi(2), Mattia Santoro(2), Lorenzino Vaccari(1), Cristiano Fugazza(1) Inter-disciplinary interoperability for global sustainability research (1) EC–JRC, Institute for Environment and Sustainability -SDI Unit (2) National Research Council of Italy GEOS 2011 - 4th International Conference on Geospatial Semantics 12-13 May 2011 – Brest, France
  2. 2. Outline 2
  3. 3. Introduction Over the next decade the global scientific community must take on the challenge of delivering to society the knowledge and information necessary to assess the risks humanity is facing from global change and to understand how society can effectively mitigate dangerous changes and cope with the change that we cannot manage. We refer to this field as ‘global sustainability research’ (ICSU, 2010). 3
  4. 4. Five ICSU Grand Challenges 2. OBSERVING Develop, enhance and integrate the observation systems needed to manage global and regional environmental change 1. FORECASTING Improve the usefulness of forecasts of environmental conditions and their consequences for people 3. THRESHOLDS Recognizing key thresholds of non-linear changes to improve our ability to anticipate, recognize, avoid and adapt to abrupt global environmental change. 4. RESPONDING Determine what institutional, economic and behavioral changes can enable effective steps toward global sustainability 5. INNOVATING Encourage innovation (coupled with sound mechanisms for evaluation) in developing technological, policy, and social responses to achieve global sustainability 4
