Terrestrial Laser Scanning

Terrestrial Laser scanning also known as High Definition Surveying (HDS) is an innovative surveying technique offering the ability to quickly capture complex and often inaccessible 3D environments.  The three dimensional data is captured through a scanning process, comprising the acquisition of thousands of points with the resultant ‘point cloud’ suitable for the creation of detailed elevations, cross sections or plans from 3D vector extraction.

Infoterra Ltd employs the RIEGL LMS-Z420i in conjunction with a Nikon D200 Integrated Camera System for Terrestrial Laser Scanning and has extensive experience of undertaking these types of surveys in all environmental climates. 

The advantages of Terrestrial Laser Scanning are:

  • High speed data capture
  • Non-contact data capture
  • Photorealistic 3D colourised point clouds
  • High level of detail suited for CAD feature extraction

Applications for Terrestrial Laser Scanning:

  • Topography and mining
  • Architecture and facade measurement
  • Forensics; accident and crime scenes
  • Structure surveys; bridges, dams, railway infrastructure
  • As-built surveying
  • Coastal and water course monitoring
  • Highway surveys
  • Archaeology and cultural heritage documentation
  • Environmental studies
  • Urban monitoring and civil engineering
  • City modelling

Data Outputs:

  • 3D colourised point clouds with intensity; XYZ, LAS, & POD formats
  • 3D mapping and cross sections
  • High resolution Digital Terrain Model up to a 20cm interval
  • Change detection reports
