Point Cloud (LiDAR)

So, Point Cloud survey data. What is it and how can we use it? That’s the question I get from many of my clients.

A point cloud is what it say’s on the tin, a cloud of millions of points captured using LiDAR technology to make up the 3-Dimensional earth we live on. A point cloud is captured using aerial, static and mobile techniques and gives you measured land with everything that sits on it. For Example (just a sample!):

  • Buildings (exterior and interior)
  • Street furniture assets
  • Vegetation
  • Road surface and assets (white lines, VRS, lighting columns)

LiDAR point cloud is considered the most efficient solution of capturing large areas or terrain, urban and rural.

Who is it used by?

  • Landscape Architects
  • Architects
  • Civil Engineers
  • Environmental consultants
  • Agriculture
  • Utilities
  • Urban/Town planners
  • Local Authorities

What is it’s uses?

  • Town/City Planning – City Modelling, identification, visualisation, design
  • Highways/Corridor – design/asset capture
  • Flood modelling
  • Arboriculture, Forestry – vegetation health detection
  • Power lines – sag detection, vegetation clash detection
  • Renewables – Solar potential analysis
  • Photomontage production
