Landsat Supplementary Data

Landsat ETM+ (28.5 m spatial resolution) data were sampled and classified to derive area estimates of forest cover and change within the biome. Stratified sampling was implemented to enhance precision by allocating greater sampling effort to areas likely to exhibit change. The strata were determined based on the MODIS-derived forest cover loss hotspot map. The biome was partitioned into a sampling frame consisting of square blocks 18.5 km per side. The 500m forest cover loss hotspot map for 2000-2005 was aggregated per block, yielding percent change for each of the blocks within the biome. The stratum boundaries were chosen guided by the cumulative square root frequency rule and the sample size allocated to each change stratum was initially determined by optimal allocation (Cochran, 1977).

Each Landsat sample block was classified using a supervised decision tree classifier to yield 2000 forest cover and 2000 to 2005 forest clearing areas. Forest was defined as greater than 25% canopy cover and change was measured without regard to forest land use. Sample block imagery and classification results can be viewed from this page.
