Forest loss year (2000-2018)

Dataset Creator Name: Matthew Hansen
Date of creation: 2019

Forest loss during the period 2000–2018, defined as a stand-replacement disturbance, or a change from a forest to non-forest state. Data in this layer were generated using multi-spectral satellite imagery from the Landsat 7 thematic mapper plus (ETM+) sensor. The clear surface observations from over 600,000 images were analysed using Google Earth Engine, a cloud platform for earth observation and data analysis, to determine per pixel tree cover ...
