LiDAR

Precision Mapping for Your Most Demanding Projects

Visualise your world with unprecedented clarity and detail. UDM Group’s LiDAR scanning services transform complex environments into actionable digital insights, delivering millimetre precision when it matters most. From sprawling infrastructure projects to detailed structural analysis, our advanced laser scanning technology captures what traditional methods miss.

What is LiDAR Scanning?

LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser light to measure distances with exceptional accuracy. By emitting rapid pulses of laser beams and measuring the time of flight for each return signal, LiDAR creates detailed 3D representations of environments, structures, and landscapes.

Originally developed for meteorological research, LiDAR technology has evolved into an essential tool across numerous industries. The LiDAR sensor collects millions of precise distance measurements, generating a “point cloud” that forms a comprehensive digital twin of physical reality, capturing details invisible to the naked eye and conventional surveying methods.

The Science Behind Our LiDAR Solutions

At its core, LiDAR operates on a remarkably straightforward principle. Our advanced laser scanners emit rapid pulses of laser light – up to hundreds of thousands per second – that bounce off surfaces and return to the sensor. By calculating the time taken for each pulse to return, the system determines exact distances to every point.

These individual measurements combine to create a 3D point cloud of extraordinary density and accuracy. Unlike traditional surveying that captures dozens or hundreds of points, our LiDAR technology collects millions of measurements, creating digital terrain models and structural representations with sub-centimetre precision.

What truly sets modern LiDAR apart is its versatility across environments and atmospheric conditions. Whether mapping distant objects in broad daylight or capturing fine details in low-light settings, our laser scanning technology delivers consistent, reliable results that form the foundation for informed decision-making.

Applications: Where LiDAR Delivers Exceptional Value

Infrastructure and Construction Projects

Our terrestrial laser scanning provides comprehensive as-built documentation with millimetre precision, dramatically reducing rework and design conflicts. Construction teams rely on our 3D models to verify existing conditions, monitor construction progress, and ensure quality control throughout project delivery. The digital elevation models we produce serve as the foundation for informed design decisions and precise quantity calculations.

Asset Management and Facilities Documentation

Capture comprehensive digital records of complex facilities and infrastructure assets. Our LiDAR scanners document every pipe, structural element, and mechanical component with exceptional detail, creating living digital assets that support maintenance planning and renovation projects. This level of documentation proves invaluable for facilities with limited or outdated as-built information.

Heritage Documentation and Preservation

Historical structures demand special care. Our non-invasive laser imaging captures intricate architectural details without physical contact, creating permanent digital records of heritage assets. These detailed 3D models support conservation planning, condition assessment, and virtual access to culturally significant sites.

Transport and Civil Infrastructure

From highways to railways, our mobile laser scanning systems efficiently capture corridor data while maintaining normal operations. Mounted on vehicles or aerial platforms, these systems collect comprehensive data sets that support alignment planning, clearance verification, and asset inventory—all without disrupting traffic flow or requiring extensive site access.

Mining and Resources

In challenging mining environments, our LiDAR solutions deliver accurate volumetric calculations, stockpile measurements, and pit surveys with unprecedented speed and safety. By eliminating the need for personnel to physically access hazardous areas, laser scanning technology significantly reduces risk while improving data quality and coverage.

Environmental Monitoring and Management

Track environmental changes with exceptional precision. Our airborne LiDAR systems can penetrate vegetation to create accurate digital terrain models of the ground surface, supporting flood modelling, erosion monitoring, and habitat assessment. For coastal and riverine environments, specialised bathymetric LiDAR captures both above-water and underwater features in a single operation.

Scan with Accuracy

Our Comprehensive LiDAR Capabilities

Terrestrial Laser Scanning

Our static, ground-based LiDAR scanners deliver the highest level of accuracy for detailed documentation of buildings, structures, and confined spaces. Ideal for complex industrial facilities, heritage documentation, and high-precision engineering applications, terrestrial applications provide unmatched detail and accuracy down to 2mm.

Mobile LiDAR Systems

Mounted on vehicles or portable backpack systems, our mobile laser scanning equipment efficiently captures large areas while maintaining excellent accuracy. This approach proves particularly valuable for transport corridors, urban environments, and large facilities where efficiency must balance with detail.

Airborne LiDAR

Deployed via aerial vehicles including drones and fixed-wing aircraft, our airborne LiDAR systems rapidly capture wide-ranging landscapes, providing comprehensive coverage of large project areas. The resulting data supports planning, design, and environmental assessment across expansive territories that would be impractical to survey by conventional means.

Integrated Multi-sensor Platforms

For the most demanding applications, we combine LiDAR with complementary technologies including high-resolution photography, thermal imaging, and radio detection systems. These integrated platforms deliver rich, multi-layered datasets that reveal not just what's visible, but what lies beneath the surface.
