Advanced Land Observing Satellite-‐2 "DAICHI-‐2" (ALOS-‐2)
ALOS-‐2/PALSAR-‐2 was launched on 24 May 2014, and is now opera)onal.

ALOS-‐2 will achieve significant contribu)ons to: n Disaster Monitoring of Damage Areas n Con)nuous upda)ng of data archives related to
na)onal land and infrastructure n Effec)ve monitoring of cul)vated areas n Global monitoring of tropical rain forests to
iden)fy carbon sinks.
L-‐band Synthe)c Aperture Radar-‐2 (PALSAR-‐2) • Wide observable area (2,320km) • Right-‐and-‐le^ looking func)on • High resolu)ons (1-‐3m) • Dual Polariza)on(HH+HV) • ScanSAR – Strip Mode SAR • capable of observing day and night, and in
all weather condi)ons. • Succesor of ALOS/JERS-‐1 using same forest

Ø JICA plans to expand their project internationally to such as Peru, Columbia(South America), Myanmar(Asia), Gabon(Africa), etc., not only Brazil deforestation Monitoring Project.
Ø At that time, it is not to be installed analysis system in each country, but it will be constructed a Forest change detection system for intensive analysis. It will be ensured the horizontal deployment efficiently.
