Mapping accurately through vegetation is challenging. And while photogrammetry can be used for bare earth mapping, it is not nearly as effective as LiDARLiDAR, or light detection and ranging, is a tool used to quickly, accurately and densely measure 3D features from the world around us. LiDAR is a form of “remote sensing” - meaning we aren’t physically measuring things with our hands, but rather, using sensors. for mapping through thick vegetation.
