FJD Trion P1 Survey for Homeowners: What You Need and Why
The FJD Trion P1 is a SLAM-based handheld lidar scanner that captures your property as a coloured point cloud — millions of measured XYZ points representing the exact geometry of your home. This data is used to produce floor plans, elevations, sections, and 3D models for architects, structural engineers, and party wall surveyors.
