Trees and Forests
The terraPulse Forest dataset is based on time-serial maps of tree cover, the percentage of horizontal area in each pixel covered by woody vegetation taller than 3 to 5 meters. The dataset is available from 1984 to present at up to 10-meter resolution for any region, as well as derivative tree- and forest-cover change and integrated stand age and time since disturbance. Through the terraPulse Land Cover Dataset, the tree-cover layer is also available as a binary measurement at 1-meter resolution, with historical coverage depending on availability of high-resolution imagery. Certainty of continuous data products (e.g., Tree Cover) is represented by Root Mean Square Error, and certainty of categorical products is represented by probability of class membership.
