3D Laser Scanning Survey for Homeowners: What You Need and Why
A 3D laser scanning survey captures your property as a point cloud — millions of measured points that represent the exact geometry of your home. This data can be used to produce floor plans, elevations, sections, and 3D models for use by architects, structural engineers, and party wall surveyors.
