Terrestrial LiDAR for High-Resolution Mapping
Higher accuracy for small sites
LiDAR is the process of using a laser beam coupled with a rangefinder to capture the shape and position of all visible surfaces and objects. The average laser scan yields more than one hundred million data points. Terrestrial, or ground-based, LiDAR is therefore suited for relatively small areas where higher accuracy is a necessity or where field crew safety is a concern.
Greater data density yields unique visualizations
The data points captured by a laser scan can be grouped into a point cloud database and manipulated using a variety of software applications to produce as-built drawings, contour maps, colorized slope maps, and other deliverables.
Non-destructive techniques for irregular and historic structures
Calculating the dimensions or volume of irregularly shaped objects or culturally significant structures can be difficult with conventional methods. WithersRavenel uses a 3D laser scanner to collect millions of data points for an object or structure, precisely capturing its dimensions and position to create a highly accurate model of a feature or site. This model provides critical information about structure performance and risks, including any structural deformation, and creates a strong foundation for preservation efforts.
