Airborne Laser Scanning

Airborne Laser Scanning (ALS) is a technology that uses laser beams from an aircraft to measure and map the Earth's surface. The aircraft emits rapid pulses of laser light, which bounce off objects like trees and buildings and return to the sensor. By calculating how long it takes for the light to return, the system can create detailed three-dimensional images of the landscape below. ALS is widely used in fields such as forestry, urban planning, and environmental monitoring due to its efficiency and accuracy in capturing complex terrain and vegetation structures.
