LiDAR, or Light Detection and Ranging, is a remote sensing method using lasers to measure distances. These can be combined into a point cloud to produce an accurate model which measurements can be taken.
The advantages of LiDAR is that unlike photogrammetry, light can penetrate vegetation to the ground floor. This means you can image detailed vegetation structures that photogrammetry would classify as a solid object, thus loosing detail.
Profiles and transects can be created, isolating specific areas to identify topography and drainage patterns. Soil displacement and movement can also be mapped by overlaying multiple surveys of the same site. differences n terrain can be identified and targeted for further investigation.
