What is a Terrestrial LiDAR Scanner?
A terrestrial LiDAR scanner is a ground-based 3D laser scanning system used to capture highly accurate measurements of real-world environments and convert them into detailed digital models known as point clouds.
At Hamilton By Design, we use engineering-grade terrestrial LiDAR scanning to support design, drafting, and construction across industrial, mining, and infrastructure projects.
How a Terrestrial LiDAR Scanner Works
A terrestrial LiDAR scanner measures distance using laser technology:
- A laser beam is emitted from the scanner
- The beam reflects off surfaces such as steel, concrete, or pipework
- The scanner records the return signal
- Distance is calculated using time-of-flight or phase shift
- Millions of measurements are captured per second
The result is a dense and accurate 3D point cloud representing the scanned environment.
What is a Point Cloud?
A point cloud is a digital dataset made up of millions (or billions) of points.
Each point contains:
- X, Y, Z coordinates
- Spatial position in 3D space
- Optional colour information (RGB)
This creates a true-to-life digital representation of physical assets, forming the foundation for CAD modelling and engineering design.
Why Use a Terrestrial LiDAR Scanner?
Accuracy
Terrestrial LiDAR scanners provide millimetre-level accuracy, making them suitable for engineering and fabrication.
Speed
Large and complex environments can be captured quickly compared to traditional survey methods.
Safety
Data can be captured without direct access to hazardous or difficult-to-reach areas.
Reduced Rework
Designs are based on real-world data, reducing clashes and site modifications.
Engineering Applications
Terrestrial LiDAR scanning is widely used across:
- Industrial plant upgrades
- Mining and processing facilities
- Structural and mechanical design
- Brownfield engineering projects
- As-built verification
- Reverse engineering
For projects requiring integration with your team, this capability can also be delivered through our engineering secondment services:

Engineering-Led LiDAR Scanning
Not all LiDAR scanning is equal.
At Hamilton By Design, scanning is performed with an engineering-first approach, ensuring the data is suitable for downstream use in CAD and design.
Key considerations include:
- Line-of-sight limitations
- Scan density and coverage
- Registration accuracy
- Data structure and usability
This ensures the output is not just a visual model, but a usable engineering dataset.
From Scan to CAD
Our workflow converts LiDAR data into practical deliverables:
Scan → Register → Model → Detail → Deliver
This includes:
- Point cloud registration (.E57, .RCP, .LAS)
- 3D CAD modelling (SolidWorks and other platforms)
- 2D drawings and fabrication-ready documentation
Terrestrial vs Other Scanning Methods
- Terrestrial LiDAR: High accuracy, long range, ideal for engineering
- Handheld scanners: Faster but lower accuracy, suited to small objects
- Photogrammetry: Visual models, not typically engineering-grade
For industrial and brownfield environments, terrestrial LiDAR remains the preferred method.
