CEOS Development Environment

Water Portal


The CEOS Water Portal Concept


The goal of the CEOS Water Portal Project is to provide assistance to scientists and general users (or non-researchers) from the water domain in the development of data services associated with data integration and distribution.


The CEOS Water Portal is built around several key concepts:

  • The Water Portal will make different types of datasets (satellite, in-situ, and model output) from various water communities accessible.
  • Portal users will include researchers in the hydrological domain as well as operational workers in water-related fields, such as river administrators.
  • The portal is connected to each data center using a standard interface protocol for real-time retrieval of the catalog and the data. (Part of the catalog is collected and stored in the portal locally.)
  • User registration and sharing of use cases/research summaries is encouraged.

CEOS Water Portal Data Partners include the National Aeronautics & Space Administration (NASA) and the National Oceanic & Atmospheric Administration (NOAA).

New Water Portal Architecture

New Water Portal Architecture


For several years in 2000s, WGISS Test Facility for CEOP (WTF-CEOP) project was tackled by the lead of JAXA to meet the demand of CEOP user community to develop the data integration services. With the fulfillment of the task, the project ended in 2009.

The WTF-CEOP successfully having demonstrated the advantages of data integration for CEOP, the request for enhanced services for water communities was motivated by Dr.Toshio Koike, the lead scientist of CEOP, to push the data integration forward and improve the accessibility to the hydrological data, or water relevant data in broader sense, which are distributed globally.

JAXA has taken the roll to expand the“WTF-CEOP” prototype system into “CEOS Water Portal ”, in which more variety of datasets and features are explored. Another essential element is that of the use by not only scientists but also by non-researchers who are dealing with those data in their daily work, such as river administrators etc.
The lead organization representing the CEOS WGISS agencies in the CEOS Water Portal Project is JAXA, with participation by NASA and NOAA. Other WGISS members and WGISS affiliates may join at a future date. The project lead is Satoko Miura, JAXA.

Portal development will continue through the end of March, 2016, at which point it becomes fully operational from April, 2016 onward.

Planned enhancements to the Portal include architecture renovation, which is to be complete by the end of March, 2015. The new architecture focuses on leveraging an open source catalog broker software (GI-cat) as well as outside catalog servers (or brokers), which will greatly simplify the total architecture and reduce the labor of catalog management without sacrificing service quality for users.
