Anais do XIX Simpósio Brasileiro de Sensoriamento Remoto

The cloud computing is a breakthrough technology being used by applications in remote sensing. The Treecover 2000 product establishes for each pixel of 30 m of spatial resolution a percentage of 0 to 100 of forest cover for the year 2000. The objective of this work was to answer the following question: What is the threshold to define a forest cover mask for year 2000 in the Amazon basin? The proportion of forests in plots of 10 km2 between PRODES for the year 2000 and GFC Treecover 2000 in five different thresholds (10-100%, 80-100%, 85-100%, 90-100% and 95-100%) were compared in XY axes. The results indicate the thresholds of 80-100% and 85-100% to create a forest cover mask from the year 2000.
