What 3D Laser Scanning covers

Traditional surveying measures specific points selected by the surveyor. Laser scanning captures everything in line of sight. Traditional is 'selective'; scanning is 'comprehensive'.

Why it matters

Complexity drives the decision. For a simple square box, a tape measure works. For a complex historic façade or a plant room, traditional methods are too slow and prone to missing details. Scanning reduces the risk of 'return to site'.
