• Uses radar images of ALOS PALSAR
• Detection of deforestation under cloud cover
• Complement to DETER system
MethodologyMethodology• Uses ScanSAR images with 100-m resolution
• Multitemporal compositions
• Mask previous PRODES & DETER polygons
• Polygons delineation and validationwith optical images (and few field campaigns)
