A 3D point cloud is a digital representation of a physical environment created from millions of measured points captured during a laser scan or photogrammetry survey. Each point contains precise spatial coordinates that collectively form an accurate 3D model of the surveyed area. Point clouds are essential for BIM modelling, engineering design, clash detection, renovation planning, and asset management. They allow project teams to analyse existing conditions with a high level of detail and accuracy before construction or maintenance begins. By using point cloud data, businesses can improve project coordination, reduce costly errors, and streamline the overall design and construction workflow.
