3D Laser Scanning

3D laser Scanning, also known as LIDAR (Light Detection and Ranging) utilizes a very rapid laser beam to scan its environment. This generates an enormous number of points in the form of a point cloud. Objects can then be modelled or spatial data can be extracted from the point cloud.

3D Laser Scanning is perhaps the most exciting and rapidly developing method of collecting survey data. Dense point clouds comprising of literally millions of co-ordinated points are created within minutes. We are now able to capture data at a rate of up to one million points per second.

SEP collect somewhere in the region of three hundred billion (although they haven’t been fully counted) full colour, 3D points per year which can all be related to OS. With so many points being collected in such a short space of time, the duration a survey team needs to remain on site can be dramatically reduced.


The added advantage of Laser Scanning above normal EDM methods is that it does away with costly revisits to site to survey for extra detail as it is already stored on the Point Cloud information in our Skelmersdale office database.  Laser Scanning applications include: Measured Building Surveys, Elevations, Monitoring, Architectural Design, Forensic and crime scene analysis, Mining and Quarrying, Heritage Projects, Reverse Engineering, 3D Modelling, Film and Animations.

SEP deliverables include: 2D & 3D DWG’s/DXF, 3D Models, Visualizations, Video Fly-through and Point Cloud Export.
