While large variations in nature cause enormous disasters in human society, the effects of human activities, such as global warming and the destruction of ecosystems, bring about a change in the natural system and become a constraint on human activities. In response to these problems, it is requested from Japan and overseas to utilize earth observation data to deepen understanding of the global environment, improve prediction capabilities, and provide information that contributes to sound decision-making in crisis management and resource management.

Data Integration and Analysis System (DIAS) started from 2006. The goals of DIAS are to collect and store earth observation data; to analyze such data in combination with socio-economic data, and convert data into information useful for crisis management with respect to global-scale environmental disasters, and other threats; and to make this information available within Japan and overseas.

The prototype of DIAS was developed in 2010. This project established the world’s first platform providing scientific information to evaluate the impact of climate change and plan its adaption measures on fields such as the water cycle and agriculture, which is based on the diverse and massive integrated data regarding earth observation, climate change prediction, etc. Then, phase II of DIAS from 2011 made further advancement and expansion to apply DIAS as a social and public infrastructure. The current project of phase III has started since 2016 with the aim of its practical operation.

The work of DIAS contributes internationally as well. DIAS is connecting to many data centers from all over the world of Global Earth Observation System of Systems (GEOSS) participating countries. DIAS is also recognized as the precedent case in terms of working most comprehensively on reviewing e-Infrastructure for interdisciplinary and super interdisciplinary collaboration within Belmont Forum, a forum among science and technology funding agencies.

In addition, DIAS works together with many projects including the Social Implementation Program on Climate Change Adaptation Technology (SI-CAT), a project that collaborates with various types of task parties/decision makers. This allows us to continue to develop and progress in building long-term and stable systems as a social platform to contribute to global social issues such as climate change adaptation and mitigation.
