The dataset is divided into 10x10 degree tiles with a spatial resolution of 1 arc-second per pixel, or approximately 30 meters per pixel at the equator. Derived from time-series analysis of Landsat images, the dataset includes information on: <br><div>Tree canopy cover for year 2000 (treecover2000) Tree cover in the year 2000, defined as canopy closure for all vegetation taller than 5m in height. Encoded as a percentage per output grid cell, in the range 0-100. <br></div><div>Global forest cover gain (2000-2021) (gain) Forest gain during the period 2000-2012, defined as the inverse of loss, or a non-forest to forest change entirely within the study period. Encoded as either 1 (gain) or 0 (no gain). <br></div><div>Year of gross forest cover loss event (lossyear) Forest loss during the period 2000-2024, defined as a stand-replacement disturbance, or a change from a forest to non-forest state. Encoded as either 0 (no loss) or else a value in the range 1-20, representing loss detected primarily in the year 2001-2024, respectively. <br></div><div>Data mask (datamask) Three values representing areas of no data (0), mapped land surface (1), and persistent water bodies (2) based on 2000-2012. <br></div><div>Circa year 2000 Landsat 7 cloud-free image composite (first) Reference multispectral imagery from the first available year, typically 2000. If no cloud-free observations were available for year 2000, imagery was taken from the closest year with cloud-free data, within the range 1999-2012. <br></div><div>Circa year 2024 Landsat cloud-free image composite (last) Reference multispectral imagery from the last available year, typically 2024. If no cloud-free observations were available for the year 2024, imagery was taken from the closest year with cloud-free data.</div>Tree coverForest gainForest lossForest change <http://www.opengis.net/def/crs/OGC/1.3/CRS84> Polygon((-180 -90, -180 90, 180 90, 180 -90, -180 -90)) Tree canopy cover for the year 2000https://storage.googleapis.com/earthenginepartners-hansen/GFC-2024-v1.12/treecover2000.txtGlobal forest cover gain over the period 2000-2012https://storage.googleapis.com/earthenginepartners-hansen/GFC-2024-v1.12/gain.txtYear of gross forest cover loss eventhttps://storage.googleapis.com/earthenginepartners-hansen/GFC-2024-v1.12/lossyear.txtData mask for the period 2000-2012https://storage.googleapis.com/earthenginepartners-hansen/GFC-2024-v1.12/datamask.txtCirca year 2000 Landsat 7 cloud-free image composite (first year)https://storage.googleapis.com/earthenginepartners-hansen/GFC-2024-v1.12/first.txtCirca year 2024 Landsat cloud-free image composite (last year)https://storage.googleapis.com/earthenginepartners-hansen/GFC-2024-v1.12/last.txtUniversity of MarylandGoogleState University of New YorkWoods Hole Research CenterUnited States Geological SurveySouth Dakota State UniversityEnglish
