Aerial surveying

LiDAR Mapping

LiDAR which stands for Light Detection and Ranging, is an airborne system that uses pulsating laser light to examine the surface of the Earth.

Combined with other data recorded by the system – these laser pulses generate precise, three-dimensional maps.

LiDAR systems allow scientists and mapping professionals to examine both natural and man made environments with accuracy, precision, and flexibility.

It is also one of the most cost-effective ways of collecting topographical elevation data over large areas. One of the biggest advantages of LiDAR over classic Photogrammetic methods is the speed at which a huge amount of highly accurate data can be measured, processed and delivered to the client. Days of LiDAR survey replace weeks of Photogrammetic observation, and an accurate surface model can be produced within 24 to 48 hours of a survey flight.

Even in the age of drones, the helicopter’s superior endurance, ability to fly at greater heights and within restricted airspaces, secures its place in this specialised market.

In addition, there are many instances when skilled personnel need to be involved in the process. Helicopters are able to carry survey engineers and specialist camera operators above the area concerned, allowing them valuable insight into the terrain.
