PCA’s survey team uses cutting-edge technology to produce LiDAR and laser scan point-cloud data processing and visualisations. To achieve this, a laser is set up at a distance of 10m from the target, which can record up to two million points per second, each accurate to within 1mm. The resulting ‘pointcloud’ data can be used to produce a high-resolution digital reconstruction that can be rotated in three dimensions. The static image shown here has been extracted from the digital record.
