LiDARteknologia

LiDARteknologia, an acronym for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses, when bounced off an object, return to the LiDAR instrument. By measuring the time it takes for the pulses to travel and return, the system can calculate the distance to the object with high precision. The data collected forms a three-dimensional representation of the environment, often referred to as a point cloud. This point cloud captures the shape, size, and spatial relationships of objects and terrain features.

LiDAR systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU). The laser scanner emits laser pulses, the GPS determines the instrument's position, and the IMU records the orientation of the scanner. Combining these data streams allows for accurate georeferencing of the collected points. Applications of LiDARteknologia are diverse and include mapping and surveying, environmental monitoring, urban planning, autonomous vehicle navigation, archaeological research, and forestry management. Its ability to penetrate vegetation can also provide detailed information about ground surface topography.
