Deforested Areas up to 1997

DIGITAL PRODES: ACRE, RONDÔNIA, MATO GROSSO, AND PARÁ ( APPROXIMATELY 80% OF DEFORESTATION ) 110 LANDSAT TM IMAGES ACQUIRED IN 1997

# EXAMPLE OF FINAL REPRESENTATION PROPOSED FOR THE DIGITAL PRODES PROJECT

MAPPING BURNED AREAS Burning occurred over recent deforested areas (orange color, 186 km2) were discriminated from those occurred over old deforested areas (red color, 964 km2) mapped using 1998 TM image. Burned areas over old deforestationa ( 84%) Burned areas over recent deforestation 16%)

MAPPING REGROWTH AREAS Regrowth CLASSIFICATION OF SEVEN REGROWTH CLASSES
