Terrestrial Laser Scanning (TLS) at CWU
The Department of Geological Sciences at Central Washington University and UNAVCO jointly own a terrestrial laser scanner that is available for research and teaching purposes to trained users.
TLS uses the technology known as lidar, or light detection and ranging, from a ground-based perspective. The TLS instrument is mounted on a tripod and emits laser pulses in a swath as it rotates on the tripod. As reflected pulses return, the scanner records the 3-dimensional location of the reflecting surface, as well as its reflectance. This allows users to build high-resolution 3D models of surfaces and objects with up to sub-centimeter precision.
