Terrestrial vs. Handheld vs. Mobile Laser Scanning

by Keith Owens | Jul 5, 2026 | Uncategorized

Terrestrial, handheld, and mobile laser scanning each trade accuracy for speed — here is when to use each.

Terrestrial vs. Handheld vs. Mobile Laser Scanning — 3D laser scanning by CAD Construct LLC

The three approaches

  • Terrestrial (tripod) — highest accuracy; the standard for as-builts and BIM.
  • Handheld / SLAM — fast walk-through capture; lower accuracy, great for quick coverage.
  • Mobile / vehicle — rapid capture of large sites and corridors.
