Terrestrial LiDAR / 3D Laser Scanning

Laser scanners take 360 degree measurements around a fixed position. Depending on the scanner, speeds up to 1,000,000 points per second are possible with ranges of 300m. They often also capture 360 degree photography in colour or greyscale which can be used to give a colour value to each measured point.

The ouput from this process is a point cloud and when several point clouds are combined together they form a geometrically acurate representation of a building or structure.

Once the pointcloud is obtained it can be used in Revit, 3DS Max, Navisworks or ArchiCAD to create or interact with existing 3D models, or it can be used in AutoCAD to create 2D plans.

It is ofen used to form the basis for redevelopment of existing buildings, documentation of plant or complex industrial environments or the presevation and documentation of historic and culturally important buildings.
