We quantified the scaling effects on forest area estimates for the conterminous USA using regression analysis and the National Land Cover Dataset 30m satellite-derived maps in 2001 and 1992. The original data were aggregated to: (1) broad cover types (forest vs. non-forest); and (2) coarser resolutions (1km and 10 km). Standard errors of the model estimates were 2.3% and 4.9% at 1km and 10km resolutions, respectively. Our model improved the accuracies for 1km by 0.6% (12 556km2) in 2001 and 1.9% (43 198km2) in 1992, compared to the forest estimates before the adjustments.Publication Notes
