2-8. Disaster Analysis Based on Satellite Information
Many earth observation satellites, with various sensors, band-passes, observation bands, resolutions
and observation cycles, are circling around the earth (see Table 2-6-1). Many satellite images areaccessible by general public and looked forward to utilizations in disaster reduction activities such as
the disaster analysis, forecast, etc (see Table 2-6-2).

In this country, take for example, the disaster reducing working group of the satellite remotesensing steering committee1 disclosed to public2 in 2000 the “Introduction to the disaster analysis
methods that utilize satellite information” which summarizes analysis examples of satellite data applied
to actual disasters and interprets the disaster analysis methods, in order to introduce extensively themethods of utilizing the satellite remote sensing technology to persons in charge of the administrationof disaster reduction at local public bodies and general public. Further, the committee opened to public3
in 2006 the “Results of forerunning analysis based on ALOS observation data”, taking the opportunity
when a long-waited start of operation of the Japanese earth observation satellite “Daichi (Good Earth)”(ALOS).
The “Introduction to the disaster analysis methods that utilize earth observation satellite information”
provides useful information for persons in charge of administration of disaster reduction as well as forresearchers in Asia. In order to assist the promotion of disaster reduction measures at member countries,
Asia Disaster Reduction Center obtained the right to print and disclose the English version, and opened4
it public.

Moreover, it is examining, jointly with Japan Aerospace Exploration Agency (JAXA), National
Institute of Information and Communications Technology (NICT) and Diamond Air Service (DAS),
new early access to disaster information and means of sharing information which utilize, among others,
Wideband InterNetworking engineering test and Demonstration Satellite (WINDS), a newcommunication satellite being planned to launch in 2007 by JAXA. (Fig. 2-6-4)
