From visual checks to 3D records for urban trees in Hong Kong

LeafIoT in Hong Kong adds FJD Trion P2 and S2 scans to the arborist’s judgement. After typhoons they can show how a tree has tilted — and cut modelling from hours into a faster digital workflow.

Urban trees in Hong Kong documented as 3D models with FJD Trion LiDAR

After typhoons, LeafIoT Technology in Hong Kong sometimes needed to show clients how an urban tree had tilted. Their platform was built around a 2D view. The practical question was how to present the tree’s form and position in three dimensions.

LeafIoT helps property managers, universities, and research groups build 3D archives of urban trees and pairs that with sensors that watch tilt and collapse risk. The arborist’s visual assessment does not disappear — but on its own it does not give the same spatial record.

P2 and S2 in one tree workflow

The team mainly scans with the FJD Trion P2 and the FJD Trion S2. The result is a digital record that can be reviewed after the field visit and used alongside the sensor feed.

From hours per tree to a faster record

Modelling or analysing a single tree after a scan used to take two to three hours. With FJD Trion Model, LeafIoT describes a workflow that is both faster and more precise — and that they link to more than an 80 percent labour-cost reduction in the step they compared.

  • Visual inspection and basic measures are joined by a 3D archive
  • P2 and S2 capture the tree and its setting in one walk
  • Trion Model extracts data that property managers and researchers can read
