LiDARszkennelésbl

LiDARszkennelésbl, often shortened to LiDAR scanning, is a remote sensing method that uses light in the form of pulsed laser to measure distances to the Earth's surface. A LiDAR unit emits laser pulses and records the time it takes for the reflected light to return to the sensor. This timing information, along with the known position and orientation of the sensor, allows for the creation of precise three-dimensional point clouds representing the surveyed area. These point clouds can then be used to generate highly accurate digital elevation models (DEMs), digital surface models (DSMs), and other spatial data products.

The technology has a wide range of applications. In environmental science, LiDAR is used for mapping forest canopy structure, monitoring deforestation, and assessing flood risks. Urban planners utilize LiDAR to create detailed 3D models of cities for infrastructure development, building height analysis, and virtual reality simulations. Archaeology benefits from LiDAR's ability to penetrate vegetation, revealing hidden ancient structures and landscapes. Furthermore, the automotive industry employs LiDAR for advanced driver-assistance systems (ADAS) and autonomous vehicle navigation, enabling them to perceive their surroundings in real-time. The accuracy and speed of LiDAR scanning make it a valuable tool for creating detailed and comprehensive spatial datasets across various fields.
