Olsson has opened a new horizon in the field of spatial analysis for its clients, with the purchase of a Terrestrial Laser Imaging, Detection, and Ranging (LiDAR) Scanner for its survey services. LiDAR scanning offers an alternative way to capture and create high-definition, 3-D models of any object or space. Compared to traditional surveying methods, Olsson’s laser scanning services create 3-D models much faster and with a higher level of detail.

The Technology

Olsson is using state-of-the-art LiDAR Scanning technology to provide detailed survey documents that capture up to 1 million points per second at 3 millimeters accuracy. The scanner creates a dense point cloud using multiple scans from different vantage points to generate 3-D models and CAD drawings. This equipment can be used in all light levels, including total darkness. High resolution imagery is also acquired during the survey, from which a virtual “fly-through” can be generated.

The Benefits

High-definition 3-D models obtained through LiDAR Scanning are far more detailed than any other technology can produce. Olsson is utilizing a LiDAR scanner that obtains measurements in a 360-degree horizontal motion and a 270-degree vertical motion. The amount of data acquired using this equipment reduces the need for additional site visits to obtain information that may have been missed or deemed unnecessary at the time. This, coupled with the reduction in change orders due to actual site conditions differing from design plans, can offer a substantial cost savings for all involved in the project.

LiDAR scanning is a fast and unobtrusive way to capture survey data. The use of the scanning technology also creates safer environments by limiting exposure to hazardous locations and situations.

The Uses

The LiDAR 3-D modeling system is very popular with designers, contractors, architects, fabricators, and asset owner/operators. Uses for high density point cloud surveys are prevalent in, but not limited to, site and engineering surveys, topographic surveys, as-built surveys of plants and facilities, and general area surveys. The system is also used for quantity and volume surveys forensic studies, mining, and historical site surveys.

With Olsson's state-of-the-art equipment and software, and with careful attention to quality control and proper calibration, LiDAR scanning can be used to produce highly accurate 3-D models for our clients.
