Five business Domains in RESTEC

World Map with RESTEC Trainees since 1977

(More than 5,000 trainees from 76countries)

For the more than 40 years, RESTEC has been receiving, processing and analyzing data from EO satellites entrusted by the Japan Aerospace Exploration Agency (JAXA) .

And now RESTEC has new focus ; how design “Solutions” to social benefit applying space technology.

“ ALOS2”(JAXA’s latest Radar Satellites)

Detect Land Deformation

using ALOS data

(A-1) Detecting land deformation in the area around Tokyo Bay from SAR data. The red indicates areas where an annual deformation of 2.5 cm has been detected.

(A-2) Zooming in on an area where land deformation has been detected, and superimposing it onto road information allows identification

of risk areas, and in turn efficient inspections and on-site surveys.

Applying Remote Sensing and GIS for Disaster

(ADB project TA-8884)

For better disaster

management,

develop systems

with combining

-Remote Sensing

-Crisis Mapping

(Open Street Map)

Target Countries;

- Armenia

- Bangladesh

- Fiji

- Philippines

Test site for TA-8884 in Fiji

Mapping Activities

Next Steps (In discussion)

Topographic Information

- Developing system to overlay the satellite imagery with

OSM mapping outputs

- Developing methodology to cooperate with disaster

response frame work (Sentinel Asia, International

Disaster Charter)

- Discussion how to reflect its outcome to the policy

(In Fiji, we are closely working with NDMO)

Ministry of Environment Japan

(MOEJ) Project: developing

methodology to evaluate climate

change impact in Small Island

States

Progress on this region:

for preparedness

Project overview

This project includes following three activities;

1. Evaluate the long-term risk of Storm Surge/Storm Wave

caused by Cyclone with developing the 3D hazard map

system as prototype

2. Developing a network for sustainable utilization of MOE

Japan’s methodology and systems for climate change

adaptation in SISs

3. Organize workshops

Evaluate the long-term risk of Storm Surge/Storm Wave caused by Cyclone

with developing the 3D hazard map system as prototype

Developing a system as a prototype to identify the hazard in coastal

area led by TC. Now we are focusing on Storm Surge and Storm Wave.

Evaluating future variations of tidal waves in Fiji

1. Simulation of past extreme

weather events (e.g. cyclones)

Track Max Wind Speed

2. Validation with Satellite

surface wind speed

Using multiple AOGMs, climate scenarios

(from JAXA EORC)

3. Simulation of extreme

weather events in

future climate with

pseudo global

warming conditions

Evaluating future variations of tidal waves in Fiji

4. Considering uncertainties, ensemble simulations are implemented

for present and future conditions.

5. Wind simulations are implemented by using the simulated wind data.

Then, future variations of tidal waves are investigated.

Conclusions

• Space Technology can contribute various aspects of

disaster management cycle

• RESTEC is mainly working for its preparedness phase and

rapid response phase and it can contribute to the early

warning of disasters.

• RESTEC is now working for south pacific island countries

in two projects introduced today and we would like to

enhance the relationship more!

Workshop will be held just after ESCAP WS

And more..

Remote Sensing for Integrated

Coastal Management (ICM)• Coastal habitats such as seagrass beds, coral reefs, mangrove and tidal

flat should be managed and maintained for sound coastal ecosystem.

• Remote sensing is one of the effective way.
