Highly detailed (30-m spatial resolution) tree species presence and distribution maps of Canada’s forested ecosystems (2019). Products include the leading tree species as well as the class membership probabilities for 37 tree species. Also shared is the distance-to-second class (D2SC) provided as an indicator of attribution confidence. These layers were produced from a 2019 Landsat image composite, geographic and climate data, elevation derivatives, and remote sensing derived phenology. Regional classification models were generated based on Canada’s National Forest Inventory using a 150x150 km tiling system.
