This data set provides stand age, forest formation, and land cover classification maps, and estimates of landscape-level above-ground live woody biomass (AGLB) for secondary forests in Rôndonia, Brazil. The Threshold Age Mapping Algorithm (TAMA) was applied to a densely spaced time series of Landsat images (1975 to 2003) to derive forest age. Forest type and land cover for 2003 were mapped with decision tree classification of three dates of Landsat imagery. The AGLB of the secondary forest was estimated by combining the forest classification map with coincident biomass estimates from the Geoscience Laser Altimeter System (GLAS).
This data set includes two classified raster files in GeoTIFF format and three comma-delimited (.csv) data files.
