LiDAR Insights

What is LiDAR?

LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser light to create a 3D model of the Earth's surface and objects on it. It works by emitting laser pulses and measuring the time it takes for the light to return to the sensor. This information is then used to calculate distances and create a detailed point cloud representation. LiDAR is commonly used in mapping, surveying, autonomous vehicles, forestry, and environmental monitoring.
