LiDAR LiDAR technology is a surveying technique that is used to map out areas of great density that are difficult to access. For example, rivers, railway lines and heavily vegetated areas such as forests. Such is its ability to ‘see through’ vegetation that it’s even been used by archaeologists in the Amazonian Rainforest to investigate the ruins of ancient indigenous communities.
How Does It Work?
LiDAR uses laser guided technology to determine ranges by targeting an object and measuring the time it takes for the reflected light to return to the receiver. This allows accurate ground data to be captured and for a digital surface model to be produced.
Why Is It Useful?
Not only is LiDAR useful for surveyors, but it also removes a large amount of human risk. Trying to gather images close to hazards is dangerous. LiDAR allows this risk to be lowered through with the use of unmanned aerial vehicles.
How Is It Deployed?
The payload is usually mounted to either a helicopter or a UAV (Unmanned Aerial Vehicle). This gives us more control and the ability to reach areas that would otherwise be inaccessible. At UTSS, we use drone mounted LiDAR.
