What is LiDAR data?
LiDAR is a radar technology that uses light to measure distances. It is often used in conjunction with other remote sensing technologies, such as GPS and aerial photography. There are a number of commercial LiDAR devices available on the market, and the technology is becoming more and more popular among engineers and students. LiDAR data is applied in a variety of important projects, such as: construction, disaster relief, avoidance systems for aircraft, etc. The nature of the various applications for this data implies that a level of quality must be maintained, hence the Quality Levels (QLs) for LiDAR data.
