LiDAR is the most suitable technology for mapping the ground through a forest's canopy. The penetrating laser pulses are able to capture ground and sub-canopy locations that are difficult to see in other airborne imagery or in ground surveying circumstances.

Light Detection and Ranging is used to detect and measure the distance of an object or surface from an optical source. LiDAR differs from photogrammetry in that photogrammetry uses passive light and LiDAR employs an active laser system. LiDAR yields an intensity with the XYZ data to provide a black and white-like image.
