Forests are essential to life on Earth — storing carbon, sheltering wildlife, and shaping our climate. To protect and restore them, we must see them as never before. Today, in partnership with the World Resources Institute, we’re announcing Canopy Height Maps v2 (CHMv2): an open source model and world-scale maps generated with it. Together, they will help researchers and governments measure and understand every tree, gap, and canopy edge — enabling smarter biodiversity support and land-managemen
