HRL Tree Cover Density Change (2012 to 2015)

The Tree Cover Density Change product is a pixel-based 100m layer based on the aggregated TCD status layers 2012 and 2015. It summarizes the extent and magnitude of tree cover density increases and decreases over time. A filtering approach with a 30% density significance threshold has been applied to differentiate between “noise” and the expected real change between both time steps. Changes in the magnitude of tree cover density will be derived, if the difference between TCD 2012 and 2015 products is exceeded by the defined significance threshold of 30%. The Tree Cover Density Change product has the following main specifications: 100m spatial resolution Tree Cover Density range of -30 to -100% and +30 to +100% Tree Cover Density significance difference threshold of 30% No Minimum Mapping Unit (MMU); pixel-based
