The story of A portrait of every tree | How the city of Merano is using new technology to protect its old trees

5 July 2023
Art or science? Both!

These beautiful photographs taken by a special laser technique (LiDAR) measure the historic tree population of Merano. No one knows for sure how many private trees are scattered around, how is their health and how they are facing the increasing heat and drought periods.

How it works: laser beams scan the survey area, recording spatial structures. The reflected beams produce point clouds, generating vast amounts of data. Through careful filtering and initial classification, the vegetation is sorted.

The goal? To create a complete inventory of private trees. Each tree will have its own digital twin—a 3D representation showing its characteristics and location. The digital twin opens up possibilities for simulating changing conditions and observing their effects, aiding decision-making in landscape and construction projects.
