TL;DR: A global, 30-m resolution dataset of percent tree cover by rescaling the 250-m MOderate-resolution Imaging Spectroradiometer (MODIS) Vegetation Continuous Fields (VCF) Tree Cover layer using circa- 2000 and 2005 Landsat images, incorporating the MODIS Cropland Layer to improve accuracy in agricultural areas.

TL;DR: The methods to create global products of forest cover and cover change at Landsat resolutions are described and the creation and use of surface reflectance products, improved selection of scenes to reduce phenological differences, terrain illumination correction, and the use of information extraction procedures robust to errors in training data are evaluated.

TL;DR: In this paper, the authors used locally fit classification trees to relate hindcast observations of "stable pixels" of forest and non-forest cover from circa-2000 to Landsat spectral measurements taken from the circa-1990 epoch of the Global Land Survey collection of Landsat images.

TL;DR: The estimates indicate a 62% acceleration in net deforestation in the humid tropics from the 1990s to the 2000s, contradicting a 25% reduction reported by the United Nations Food and Agriculture Organization Forest Resource Assessment.

TL;DR: The authors showed that the major reason underlying this discrepancy is ambiguity in the term "forest" and proposed a new definition of "forest cover" based on uncertainty in the definition of forest.
