LiDAR

Light and Distance Ranging

What is LiDAR?

Light and Distance Ranging, or LiDAR, are systems that create a point cloud with the data pinging back from the objects on the ground. These points are the raw material for 3D models. Most importantly LiDAR collects so much data that it can penetrate vegetation and provide information of the ground surface despite thick foliage (bare earth).

What is LiDAR used for?

LiDAR data don’t have photographic detail, that is the laser pulses themselves won’t give you the colors of items on the ground. However, the simple x, y, and z coordinates of these data point can provide comprehensive pictures of any surface. Flying a LiDAR drone is a way to quickly and safely gather information about any kind of ground-based site or feature. This encompasses a range of uses — from performing safety inspections to inspecting the progress of mining or agriculture or even estimating the size of a resource stockpile from the air.

LiDAR and you

Some clients may consider adopting LiDAR for roles that were previously served by other surveying methods, such as with total stations and GNSS receivers.

Wherever there’s a need for surveying and modeling with centimeter-level accuracy, LiDAR could be the new technology of choice. Over the next few years, buoyed by the systems’ greater availability, adoption may expand out to new industries and use cases.
