Topographic Survey with LIDAR drone

LIDAR (Light Detection and Ranging) technology on drones is a remote sensing system that uses laser pulses to measure distances and create high-resolution three-dimensional models of the environment. This technology has been widely accepted in mapping, surveying, protection and monitoring applications in various sectors, such as agriculture, construction, environment, infrastructure and scientific research.

The LIDAR system on a drone typically consists of a laser scanning device, a receiver to return the signal, and a global positioning system (GPS) for precise georeferencing of the collected data. The LIDAR sensor emits short-duration infrared laser pulses toward the ground or objects, and the time taken for the pulse to return to the sensor is measured. Based on this time measurement, the distance between the sensor and the object hit by the laser can be highly accurate.
