Lidar: Lidar (light detection and ranging) is essentially a mobile laser scanner which we attach to an aircraft or vehicle. It emits close to 2 million laser pulses per second which reflect off the ground and other surfaces.
Reflection and Return: Upon hitting a surface, the laser pulses bounce back towards the Lidar sensor. The time it takes for the laser pulses to return to the sensor is recorded. Our scanners analysis the full waveform of each returning pulse, allowing multiple targets per pulse to be collected. This is how Lidar “sees through” vegetation and water.
Data Collection: The Lidar system records the precise time it took for the laser pulses to return and the angle at which they were emitted. This information is used to calculate the distance from the sensor to the point on the surface where the laser pulse was reflected.
Point Cloud Generation: These distance measurements are collected over a large area, resulting in a dense set of 3D data points. These data points are referred to as a “point cloud.” Each point in the cloud represents a specific GPS coordinate location on the Earth’s surface and are accurate to within a few centimetres.
Data Processing: The point cloud data can be further processed to create digital elevation models (DEMs), digital terrain models (DTMs), or 3D representations of the landscape, objects, and features. These data products are valuable for various applications, including topographic mapping, land surveying, forestry management, urban planning, and infrastructure design.
