First of all, what exactly is Lidar? Simply put, Lidar is a remote sensing technology and measurement method. It uses a laser scanner to measure the distance and size of landscapes and buildings.
Lidar sends light pulses to objects such as buildings and obstacles, and then the sensor measures the time it takes for the light waves to bounce off the obstacle or surface and return to the system. The lidar system then uses the speed of the light pulse to calculate the measured value.
