3D Terrestrial Laser Scanning
Terrestrial Laser Scanning (TLS) is an advanced surveying technology that uses millions of LiDAR laser measurements to capture highly detailed, three-dimensional spatial data of existing sites, structures, and infrastructure. The result is a precise digital representation—or "digital twin"—that accurately documents existing conditions for design, construction, analysis, and long-term asset management.
Keystone Land Surveying utilizes high-density laser scanning to provide clients with comprehensive point cloud data, 3D models, and accurate existing conditions that significantly reduce field revisits, improve project coordination, and minimize costly construction errors.
Terrestrial Laser Scanning is an ideal solution for a wide variety of applications, including:
Existing conditions documentation for renovation and expansion projects
Creation of highly accurate 3D models and digital twins
Verification of mechanical, electrical, and plumbing (MEP) installations
Concrete floor flatness and levelness analysis, including identification of high and low areas
Bridge, tunnel, and transportation infrastructure inspections
Roadway and railway corridor mapping
Industrial facilities, manufacturing plants, and complex process equipment documentation
Historic preservation and architectural documentation
Building Information Modeling (BIM) and Scan-to-BIM workflows
Construction progress monitoring and quality assurance
As-built documentation and facility management
By capturing millions of accurate data points in a matter of minutes, terrestrial laser scanning provides owners, architects, engineers, contractors, and facility managers with the information they need to make confident decisions, improve project efficiency, and reduce construction risk.
