**7.5 3D laser scanning**

The main advantages of using 3D laser scanning are, for example, scanning a building or a road and obtaining measurements and information about the objects or building. This information can later be used for structural redesign, architectural redesign and dimensions. There are many applications for this technology that allows improving accuracy, time consumption and safety when it comes to scanning. It is not easy to draw a line between surveying, construction, engineering and architecture when discussing laser scanning.
