Terrestrial LiDAR

Updated: Sep 12, 2018

Terrestrial LiDAR scanners don’t move. They’re not mobile and they’re not airborne. They are, however, highly accurate and comparatively simple and inexpensive.

Use terrestrial LiDAR for a very specific area of interest, such as scanning underpasses and bridges. The accuracy of these systems is very high, but the ability to collect information is limited by the fact that they’re stationary. Thus, while not as efficient for large-scale mapping projects as the other three types of scanners, they are a great way to survey very detailed and accurate projects in a short period of time.

A terrestrial scanner operates on a survey tripod. There’s no need for an IMU, but they sometimes have a GPS. The scanner scans in a horizontal and vertical fashion across the area of interest.
