Mapping the World's Forests with Greater Precision: Introducing Canopy Height Maps v2
Meta AI, in collaboration with the World Resources Institute, has released Canopy Height Maps v2 (CHMv2), an open-source model and accompanying global maps for precise forest monitoring. This new version utilizes Meta's DINOv3 self-supervised vision model, significantly improving accuracy and detail over its predecessor. The enhanced model, with an R² score jumping from 0.53 to 0.86, provides sharper canopy maps and more reliable predictions for tracking forest health, carbon storage, and restoration efforts. AI
IMPACT Enhances global forest monitoring capabilities, supporting climate action and biodiversity efforts with more accurate tree data.
