What does lidar stand for?

Lidar stands for Light Detection and Ranging. This technology is used to measure distances by illuminating a target with laser light and analyzing the reflected light. It functions by emitting short pulses of laser light and then timing how long it takes for each pulse to bounce back after hitting an object. This time delay allows for precise measurements of distance, which can be used to create detailed 3D maps of the environment.

The term "light" in Lidar refers to the laser light used for detection, while "detection" indicates the process of observing the return signals, and "ranging" highlights the ability to calculate distances accurately. This method is widely employed in various applications, including topographic mapping, forestry, and urban planning, due to its ability to provide high-resolution spatial data efficiently.
