LiDAR (3D Laser Scanning)
Instead of holding a prism at every point we need to measure, LIDAR sensors spray light beams to all objects in its field of view to collect point data at a desired interval (as little as every few millimeters). This creates a point cloud with xyz measurements on every point in the cloud. The point clouds are reconciled with digital photos, and the result is a color 3D model of the project site. We can then choose from a variety of renderings and choose which points and linework will be added to CAD drawings and DTM’s.
