LiDAR
LiDAR, or Light Detection and Ranging, is a technology that uses laser light to measure distances. A LiDAR system sends out rapid pulses of laser light and measures the time it takes for the light to bounce back after hitting an object. By analyzing these reflections, it creates detailed, 3D maps of the environment, revealing shapes, elevations, and even vegetation. LiDAR is widely used in various fields, including geography, forestry, and urban planning, helping to gather precise data for research, planning, and resource management. Its accuracy and detail make it a powerful tool for understanding our world.

Lidar, short for Light Detection and Ranging, is a remote sensing technology that uses laser light to measure distances. It works by sending out laser pulses and recording how long it takes for the light to bounce back after hitting an object. This information helps create detailed, accurate 3D maps of the ground and surrounding objects, which is useful in various fields like environmental monitoring, urban planning, and autonomous vehicles. By analyzing the reflected light, Lidar can reveal information about the shape and material of surfaces, even capturing features hidden by vegetation.
