GEO 2017-2019 Work Program

 

Data Analysis and Integration System (DIAS)

Activity ID: 83

Overview

The Data Integration and Analysis System (DIAS) Community Activity for 2017 – 2019 GEO Work Program will encompass the present DIAS, Water Cycle Integrator (WCI), Asian Water Cycle Initiative (AWCI), and African Water Cycle Coordination Initiative (AfWCCI) CAs and will coordinate their activities in line with the GEOSS Water Strategy recommendations. At the same time, DIAS CA will continue to use the Integrated Global Water Cycle Observations (IGWCO) Community of Practice for coordination with other Water SBA activities.

The Data Integration and Analysis System of Japan (DIAS) is an advanced GEOSS-compliant e-infrastructure component that addresses the challenges of a large increase in the volume of Earth Observation data by developing a core system for data integration and analysis.  In the arena of water, DIAS has been developing the Water Cycle Integrator (WCI) function, which enables a holistic approach towards solutions to water-related issues by (i) harmonization of data collection and management and improvement of data interoperability and (ii) providing tools for integrating observations, modeling, research, analyses, and management systems across SBAs. The WCI efforts have been reflecting on the experiences of the Asian Water Cycle Initiative (AWCI) and responding to the community requirements in the data and science integration field. The AWCI community has exploited the DIAS and WCI capabilities and demonstrated extensively their potential. The WCI function has also been recognized by the African Water Cycle Coordination Initiative (AfWCCI) community as a powerful tool for implementing Integrated Water Resources Management (IWRM) in transboundary basins and plans have been outlined for pilot projects.

Activities for the period

DIAS Community Activity goal is to enable effective and efficient exploitation of earth observation for truly informed decisions in water resources management and disaster risk reduction. This requires a variety of activities that include following objectives:

  1. Continue and improve data management covering the full data life cycle while regarding the “Big data” characteristics and in particular expand water-cycle relevant data acquisition and increase its availability and use for research as well as operational use;
  2. Advance development of WCI component on DIAS with new tools and functions for interdisciplinary and transdisciplinary collaboration reflecting on (a) user community requirements and (b) opportunities arising from new earth observation capabilities and technologies;
  3. Improve understanding of water-related disaster risks and resilience and identify changes in these risks and resilience through research activities exploiting earth observations and novel capabilities of WCI;
  4. Provide improved decision and policy-making support including flood early warning systems, drought monitoring and warning systems, and climate change assessment and adaptation planning tools. Promote and facilitate implementation of these systems in operational use.
  5. Human resources capacity building for water issues using inter- and transdisciplinary approach of WCI; 
  6. Foster regional collaboration and enhance user engagement through AWCI and AfWCCI frameworks and expand collaboration with other regional and global frameworks and donor organizations.

Future plans

DIAS CA will continue its efforts to populate the DIAS archive with more water-related data and assure their quality and compliance with interoperability standards. This includes satellite-derived data and products by Japan Aerospace Exploration Agency (JAXA), numerical weather prediction and reanalysis outputs by Japan Meteorological Agency (JMA), climate model outputs, and in-situ observations by AWCI countries and AfWCCI river basin authorities and organizations. Efforts on providing a smooth access to data in other archives will be continued by the Committee on Earth Observation Satellites (CEOS) Water Portal activity led by JAXA in cooperation with CEOS.

Resources

The DIAS system development and administration continues to be funded from national funds of Japan under the DIAS Program project. The resources for the WCI tool development activities are contributed by the involved researchers’ home organizations, in particular UTokyo, ICHARM, and JAXA. Several pilot implementations of WCI function in AWCI countries are currently carried out as part of individual projects under specific programs of contributing and collaborating organizations (ICHARM, JAXA) or donor organizations (Asian Development Bank - ADB, JICA, World Bank, UNESCO). Support from donor organizations will be also sought for operational implementations in AWCI and AfWCCI regions in collaboration with the national and/or river basin authorities. The DIAS CA coordination function is provided by UTokyo with the support from Nippon Koei Co., Ltd.
