Stevens Surveys is excited and proud to be the first survey firm in Manitoba to own the Leica ScanStation2 laser scanning system. The newest technology available to surveyors, high-definition surveying (HDS) is a non-intrusive method of rapidly and accurately collecting the detailed shape of targeted objects.
The process, also known as 3D laser scanning, or LIDAR (light detection and ranging), involves the use of a laser to emit a pulse of light. The time before the reflected light is detected is used to determine the distance to the object and the orientation of the laser determines the direction to the object. The result is a three-dimensional position of the target point. The reflectivity of the object is represented by the intensity of the reflected light. As many as 50,000 points per second can be scanned, each to an accuracy of only a few millimetres.
Accuracy, Robustness, Speed & Overhead Capabilities
We chose the Leica system not only for its accuracy, robustness, and speed, but also because of its ability to scan directly overhead, unlike other competitors. This poses a great benefit when working in confined spaces.
Enjoy Faster Project Turnaround in a Cost-Effective & Safe Manner
High-definition surveying benefits both client and surveyor. It offers cost advantages, faster project turnaround, improved safety, and more complete and higher quality data capture. At a comparable price to traditional survey methods, the client receives significant added value:
Traditional survey methods are limited to measuring one point at a time. HDS laser scanners remotely capture the intricate shape and geometry of targeted objects at the rate of thousands of points per second, whether it is building structures, mechanical installations or landscape.
Completing the field work is only half of the job. The millions of recorded points, called point clouds, produced by the scanning operation are generally not used directly, other than for simple visualization. Extracting information from the point clouds and translating it into results which the client can understand and depend upon is critical.
