Aerial Survey & LiDAR

LiDAR

Airborne LiDAR consists of a high frequency laser scanner that records the time differential between the emission of the laser pulses and the reception of the reflected signal from the environment. By combining this data with the position and orientation of the scanner (determined by differential kinematic GPS and an Inertial Measurement Unit) LiDAR creates highly accurate and detailed models of the earth’s surface with a height accuracy down to +/- 10cm.

LiDAR scanners can also be mounted on ground vehicles and on tripods for traditional ground survey style usage. They can also be used to capture as-built constructions, including building interiors and exteriors, pits and stockpiles. The platform used depends on the scale of the project and the nature of the site.
