What is a point cloud?
A point cloud is a set of 3D data points in a three-dimensional coordinate system. From a 3D laser scanner, these points are usually defined by X, Y, and Z coordinates, along with values representing the intensity of the returned laser signal and sometimes RGB colour values. They are usually intended to represent the external surface of an object.
Point clouds in surveying
Spatial Dimensions offer a complete data capture service using the latest laser scanning technology to conduct our point cloud surveys. From this data, we can produce 2D drawings and 3D models ranging from large scale city models to small M&E components.
The point cloud information captured by our laser scanners can be used by architects, designers, and BIM coordinators to facilitate design, analysis of proposals and clash detection to prevent costly onsite construction variations.
Point clouds can generate very large data sets, made up of billions of points. In order to work directly with this data specialist software is required. There are a variety of plug-ins which make it accessible in standard 3D CAD packages such as AutoCAD, Civil 3D, Revit and Bentley MicroStation.
One of the additional benefits of these large data sets is that the scanner naturally usually captures data above and beyond the original specification. This extra data provides extra contextual information and can be drawn upon at a later date, without the need to revisit the site, saving valuable time and money.
The point cloud can also be published in Leica TruView™ format. TruView™ is a web-based collaboration tool that allows authorised users to navigate around the point cloud data. It is quick and easy to use, and coordinates and measurements can be extracted and marked up, allowing all stakeholders in the project a seamless collaborative experience.
We offer this as a hosted service to our clients via our online client portal on this website.
