UAV-Based LiDAR for Forestry Management
Forestry management increasingly relies on high-resolution data to monitor and improve forest health, growth, and resource allocation. Unmanned aerial vehicles (UAVs), often referred to as drones, have emerged as a powerful platform for collecting such data, particularly when equipped with LiDAR sensors. LiDAR, which stands for Light Detection and Ranging, calculates the distance to objects by emitting laser pulses and measuring the time it takes for the reflected signal to return. This technology enables the creation of detailed three-dimensional (3D) models of forests, providing invaluable insights into canopy structure, tree height, and forest stand density.
UAV-mounted LiDAR systems offer several advantages over traditional ground-based methods. They provide rapid data acquisition over large areas, reducing the time and resources required for forest surveys. UAVs can access difficult terrain that may be inaccessible by foot or vehicle, enabling comprehensive data collection in varied landscapes. Moreover, LiDAR sensors on UAVs can penetrate vegetated canopies, revealing the underlying organization of trees and allowing for accurate assessment of forest biomass.
