JJ-FAST team is developing a next-generation deforestation detection algorithm (version 2) to increase number of deforestation detection, and improve detection accuracy. To validate deforestation sites detected by the new algorithm, a JJ-FAST team visited some sites in Brazil on Feb. 22, 2018. When the team accompanied by IBAMA (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renovaveis) arrived at one site, a bulldozer was mowing down trees. Two forest loggers were caught red-ha...

The Advanced Land Observing Satellite-2 (ALOS-2) is follow-on mission from the "DAICHI" , which contributed to cartography, regional observation, disaster monitoring, and resource surveys. ALOS-2 will succeed this mission with enhanced capabilities. Specifically, JAXA is conducting research and development activities to improve wide and high-resolution observation technologies developed for DAICHI in order to further fulfill social needs.

1) Disaster monitoring of damage areas, both in cosiderable detail, and when these areas may be large

2) Continuous updating of data archives related to national land and infrastructure information

3) Effective monitoring of cultivated areas

4) Global monitoring of tropical rain forests to identify carbon sinks.

The state-of-the-art L-band Synthetic Aperture Radar-2 (PALSAR-2) aboard ALOS-2, which is an active microwave radar using the 1.2GHz frequency range, will, in responding to society's needs, have enhanced performance compared to DAICHI/PALSAR. The PALSAR-2 is capable of observing day and night, and in all weather conditions.
