What is Airborne Lidar?
Airborne Lidar is the use of laser light mounted on the aircraft to detect or measure objects. Lidar is an abbreviation for the detection and range of light, the detection technology that emits the rays of photons with wavelengths in ultraviolet, infrared or visible light electromagnetic spectrum. When the photons hit and reflect the object, Lidar detects the scattered light and interprets it to provide information about the goal. Lidar is very similar to radar that uses radio waves in the same way as Lidar uses light, but Lidar can be much more accurate because it uses electromagnetic radiation with much shorter wavelengths. Airborne Lidar is used for purposes such as mapping and exploration, in scientific fields such as biology and geology, and in military detection equipment.
The most common use of Air Lidar is to study and measure topography or surface features, earth. Lidar ofThe aircraft mounted on the plane can scan the ground down with greater accuracy and resolution than conventional air photography, allowing it to detect and measure very small or fine terrain elements. The global positioning system, the satellite navigation system, is used to accurately monitor the passage of time and movement of the aircraft as it flies to create a record of where the Lidar system was at any moment of the survey. This makes it possible to produce extremely accurate and detailed topographic maps. Lidar can also penetrate vegetation, such as tree canopies, so it can accurately map the terrain covered with normal air observation because of forests or jungles.
The great accuracy of possible accuracy in Air Lidar means that repeated surveys can detect very small changes over time. As a result, it is useful in studying natural phenomena, such as the movement of glaciers and geological errors that are extremely slowly over thousands or millions of years and therefore require very accurate measurementsto detect and measure. It may also show gradual changes in the landscape caused by natural forces such as wind and water erosion. Aviation Lidar survey is also used in agriculture and provides information on land composition, topography and erosion samples. It can also measure trees and vegetation, which is useful for forest management.
In addition,Airborne Lidar is useful in studying underwater areas. It is implemented in bathymetry, measuring seabeling and lake floors, mapping shallow areas such as coast and rivers. This allows you to explore the area more quickly than it could be done with Sonar transmitted by ships. It is also useful for studying very shallow or dangerous areas where the ship is impractical or dangerous and for studying environmentally sensitive areas without penetrating the local ecology. In military applications, Lidar Systems carried by helicopters can detect naval mines.
