JAXA's G-Portal Approach to Global Observation Satellite Big Data

Abstract:

JAXA released “G-Portal” as a portal web site for search and deliver data of Earth observation satellite in February 2013.

G-Portal handles ten satellites data; GPM, TRMM, Aqua, ADEOS-II, ALOS(search only), ALOS-2 (search only), MOS-1, MOS-1b, ERS-1 and JERS-1.

G-Portal provides over 5.17 million products and the number of catalogues is over 14 million.

Currently, G-Portal receives processed satellites data without any time lag and users can search and download in a timely manner.

In the future, G-Portal will not be able to respond same as now because data size and varietieswill increase. (Observational data and variety of satellites will grow significantly)

Satellites which will be scheduled to launch in the coming years will create 660,000 products and distribute 7.6TB in a day.

Even in such a situation, G-Portal must provide same performance to user for searching and distribution.

This paper will provide how the G-Portal will evolve to support the Big data
