Who We Are
Cities are living systems - and trees are some of their most valuable assets. At
greehill
, we’re building the world’s most detailed
digital twins of urban forests
, mapping every individual tree in a city in 2D, 3D, and beyond.
By combining
cutting-edge laser scanning
,
AI
, and
machine learning
, we give cities the insights they need to maintain, protect, and grow their green infrastructure. The result? Smarter operations, healthier citizens, and cities that are more resilient to climate change.
We’re helping redefine what “smart cities” really means - and we’re doing it globally, with teams in
Budapest (HQ & R&D), Singapore, Hannover, San Diego or Paris.
