Dataset Abstract:

Age since cut, derived as first transition from primary forest to non-forest class. Derived from Decision Tree classified land-cover maps, georectified to INPE digital PRODES, SAD-69, UTM zone 20 south.
Age classes: Base date 2000: 0 = uncut 50 = Rock/Savanna 1-25 = age relative to the year 2000 (ie, 25 = cut by 1975, 12 = cut by 1988). Ariquemes ages: 25, 16, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 (note, 1999 image cloud contaminated). Ji Parana ages: 22, 14, 12, 11, 10, 7, 4, 3, 2, 1 Luiza ages: 14, 12, 11, 10, 8,5, 4, 3, 1 All were edge masked. Period covered: Ariquemes: 1975-1999 Ji Parana: 1978-1999 Luiza: 1986-1999 Data files are provided for each of the three study areas in ENVI Standard format, each with an accompanying header file, and can be viewed with any ENVI viewer.
