Laser Scanning (lidar)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Laser scanning with LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser pulses to measure distances accurately by analyzing the time it takes for the light to reflect back from surfaces. It is commonly used to create detailed 3D maps of environments, objects, and landscapes, enabling applications across various fields such as surveying, autonomous vehicles, forestry, archaeology, and urban planning.
