Activities and Management Structure

Data Integration and Analysis System Program is upgrading and expanding DIAS while concurrently building a prototype workbench by which stakeholders from different disciplines can cooperate in integrating massive and diverse data and information to create new value. In a move toward the resolution of global-scale issues, the project also aims to design and deliver an application framework that can realize public benefit through the demonstration of sustained scientific excellence and its practical application.

The Earth Observation Data Integration & Fusion Research Initiative (EDITORIA)

The University of Tokyo founded The Earth Observation Data Integration & Fusion Research Initiative (EDITORIA) April, 2006 in cooperation between several research groups taking a role in public policies, such as global earth observations, information science-technologies, disasters, and agriculture.

EDITORIA aims to create information which contributes to a sound decision making in risk management and resource controls through a deep understanding of the global environments, to improve the prediction capabilities, by an effective utilization of the various, massive earth observation data from heterogeneous sources of information.

EDITORIA is entrusted with a research about DIAS which the Ministry of Education, Culture, Sports, Science and Technology (MEXT) started as a part of National Basic Technology towards the 3rd Science and Technology Basic Plan from 2006. EDITORIA developed a demonstrative data system that integrates earth observation data effectively and efficiently and led the world in disseminating research results as a breakthrough of understanding, forecasting and corresponding within global environmental change, especially water cycle change from the global scale to the river basin scale and influence on water management system and society.
