	Laser scanning is a method of collecting surface data using a laser scanner which captures the precise distance of densely-scanned points over a given object at rapid speed. The process is commonly referred to as a point cloud survey or as light detection and ranging (LIDAR, a combination of the words 'light' and 'radar'). It can be used to generate 3D imagery that can be converted for use in 3D computer aided design (CAD) modelling or building information modelling (BIM).Instrumentation comprises high-speed lasers with an integrated camera using colour coding mounted on a tripod. Typically such instruments operate up to a range of 180 metres and at speeds of up to 990,000 points per second.

	Laser scanning has proved to be much quicker, more accurate and cheaper than conventional survey measurement. The accuracy of the process depends on the steadiness of the instrument base and the distance from the object. Close range objects achieve sub millimetre accuracy. For normal terrestrial survey work + or – 2mm per 100m is a good guide to accuracy. Greater distances of 2 kms may be accurate to + or – 50mm.
