Description

DIAS (Data Integration and Analysis System) aims at delivering relevant information within Japan and to the world for solving societal issues on earth environment based on the integration of massive and diverse earth observation data with other types of data such as socio-economic data. DIAS is unique in the establishment of a community to support application development on data infrastructure, in addition to the construction of data infrastructure itself. We first introduce the concept of DIAS from the viewpoint of three systems, namely infrastructure system, application development, and R&D community. We then summarize DIAS's principle on data sharing in terms of data access, metadata, and data policy. As a case study on DIAS's contribution to solving international societal issues, we introduce flood management planning in Tunisia based on data analysis and integration on climate change projection data. The paper concludes with our thought on some of important directions in DIAS research and development toward the future.
