The laser scanners are also used to identify with precision and accuracy the areas affected by more or less noticeable degradation.
The survey of railway sections and galleries is one of the most important fields of application of scanner: the laser scanner detects the geometry of an environment and provides high resolution images in grayscale regardless of lighting conditions.
For their remarkable speed to capture the laser scanners are ideal for measurements from mobile platforms (even up to 120 km / h). This is particularly interesting for the survey of tunnels, railways and road assets.
For infrastructure and land survey the laser scanners are used not only for detection of rail and road networks, galleries, cities, bridges, trees and forests, but also for long-term monitoring (buildings, land, etc .. ).
