2-9. Promotion of “Sentinel Asia” project“Sentinel Asia” is a project to share the disaster-related information such as the earth observation
satellite imagery, etc. on the Internet in order to utilize in the management of disasters in Asia andPacific regions. Central players of the project are the disaster reduction organizations in Asia, including
the space organizations participating in APRSAF (Asia-Pacific Regional Space Agency Forum), ADRC
and its member organizations (see Fig. 2-7-1).

Framework of Sentinel Asia

Out of the services provided by Sentinel Asia, ADRC promotes supports for the use of the system
which observes situation at the site in the event of disaster using an earth observation satellite anddistributes the finding quickly to space organizations and disaster reduction organizations in the victim
country. The system that uses the earth observation satellite “Daichi” (ALOS) launched in January 2006
by JAXA started its service formally from October in the year. In November 2007, Indian Space
Research Organization (ISRO) joined in the satellite imagery presenting organization.
ADRC serves as the contact when an emergency observation is required in the event of disaster.
Upon receipt of request for emergency observation, ADRC evaluates whether it is acceptable or not
depending on the scale, status, etc. of disaster, and requests an observation to the observation
organizations (JAXA and ISRO, as of March 2008).
