Airborne LiDAR Mapping
Airborne LiDAR is a method of collecting LiDAR data from an aircraft or helicopter. The LiDAR sensor is mounted on the aircraft or helicopter, and it emits laser beams that hit the ground surface below. The reflected signals are then collected by the LiDAR sensor, which measures the time it takes for the laser beams to bounce back. Based on this time, the distance between the sensor and the ground surface is calculated, and a 3D point cloud of the terrain is generated.
Airborne LiDAR is a widely used method for collecting high-resolution elevation data over large areas. It can cover large areas quickly, and the resulting data can be used for a variety of applications, such as topographic mapping, forest inventory, land-use planning, and hazard mitigation. Airborne LiDAR is especially useful for areas with complex terrain, where ground-based or mobile LiDAR may be challenging to use. Airborne LiDAR is also a cost-effective method compared to traditional surveying methods for large-scale mapping projects.
