Lidarteknologiassa, or LiDAR technology, refers to a remote sensing method that uses light in the form of a pulsed laser to measure variable distances to the Earth. LiDAR is often described as a combination of radar, which uses radio waves, and sonar, which uses sound waves. LiDAR's name is an acronym for Light Detection and Ranging.

LiDAR technology works by emitting rapid laser pulses and measuring the time it takes for them to reflect off objects and return to the sensor. By calculating the time of flight for each pulse, the system can determine the distance to the object. This information, combined with the sensor's position and orientation, allows for the creation of highly detailed three-dimensional maps of the surrounding environment.

The applications of LiDAR technology are diverse and rapidly expanding. It is extensively used in surveying and mapping, providing precise topographic data for infrastructure projects, urban planning, and environmental monitoring. In autonomous vehicles, LiDAR acts as a crucial sensor for real-time object detection, navigation, and obstacle avoidance. Forestry relies on LiDAR for canopy height estimation and forest inventory. Archaeology utilizes it to uncover hidden structures beneath vegetation. Other fields benefiting from LiDAR include atmospheric science, geology, and even entertainment for creating virtual environments.
