3D measurement

Thanks to their scientific and technical skills on 3D measurements, Terranum can carry out acquisitions, processing and interpretation of LiDAR and photogrammetric 3D point clouds, especially for:

  • Terrestrial and mobile LiDAR
  • Photogrammetry
  • 3D topography imaging
  • Point cloud quality assessment
  • Structural and engineering geological analyses
  • Rockfall detection and quantification
  • Landslide displacement and slope deformation monitoring
  • Coupling with InSAR (spaceborne or terrestrial) and
    other geotechnical instrumentation
  • Cavity deformation monitoring
  • Infrastructure surveying



  • Terrestrial LiDAR
  • Boat-based Mobile LiDAR
  • Photogrammetry
  • InSAR (spaceborne or terrestrial)

TLS and photogrammetry data processing

  • Level 0: outliers filtering + xyz coordinates and signal intensity exportation in text file
  • Level 1: level 0 + point clouds alignments (for several scans)
  • Level 2: level 1 + point clouds georeferecing
  • Level 3: level 2 + complete vegetation filtering

MLS data processing

  • Level 2 minimum: outliers filtering + point clouds georeferecing + vessel attitude and point cloud exportation
  • Level 3: level 2 + complete vegetation filtering

LiDAR-based expertises

High-quality and customized expertises based on LiDAR data can be carried out according to your need for structural analysis, rockfall detection, landslide displacement monitoring, cavity deformation monitoring, volume estimations and even infrastructure surveying.
