Results from time-series analysis of 654,178 Landsat images in characterizing forest extent and change, 2000–2012.
Trees are defined as all vegetation taller than 5m in height and are expressed as a percentage per output grid cell as ‘2000 Percent Tree Cover’.
‘Forest Loss’ is defined as a stand-replacement disturbance, or a change from a forest to non-forest state.
‘Forest Gain’ is defined as the inverse of loss, or a non-forest to forest change entirely within the study period. ‘Forest Loss Year’ is a disaggregation of total ‘Forest Loss’ to annual time scales.
