WebAug 28, 2024 · A far as I know, LiDAR signals do not get returned over water bodies. It depends which laser wavelength was used in the survey. If it was a wavelength near the infrared (> 700 nm) it should be partially reflected/absorbed by water, and they are usually considered to be noise (see JeffreyEvan's comment).On the other hand, there are laser … WebThe answer is “it depends”. LIDAR generally used near-infrared light, which doesn’t scatter as bad as visible light. That being said, it isn’t magic. If water is cloudy for your eyes, it is cloudy for the laser too. You might be able to map farther out with the LIDAR than with your eyes, but the range will still be pretty limited if the ... small space counter height dining setsWebAug 1, 2024 · Lidar is capable of sensing and mapping areas at night or underground, in low- light or constrained environments.
