Aerial & 3D Data
LiDAR & 3D Laser Scanning
A laser scanner measures millions of points and records their position from the light that returns, rather than from a prism. That difference is why it reaches into places photogrammetry cannot go and delivers millimetre accuracy on surfaces that photographs would blur.
Typical accuracy · ±5mm on many individual scans, typically ±10mm on the registered cloud.
When you need it
- →Vegetation hides the ground and you need the earth surface underneath.
- →You need millimetre accuracy on geometry rather than centimetre accuracy.
- →The subject is vertical, curved or inside a building, where overlap is impossible.
- →A heritage, industrial or complex asset has to be captured completely.

Questions we get asked
LiDAR or photogrammetry?
Use photogrammetry where the surface is bare, open and roughly horizontal, because it is faster and cheaper. Use laser scanning where you need millimetres, where surfaces are vertical or curved, or where vegetation is in the way.
Can it see through trees?
No scanner does. What it does is record a return from the ground beneath the canopy where enough light reaches it, so you can filter the vegetation and keep the earth surface. That is the whole point.
