Topographic LiDAR is an airborne instrument which fires a huge stream of laser pulses to the ground and records the returning signal that is reflected form the surface below. It has the unique capability to penetrate the vegetation and capture the ground under forest trees. By measuring the time delay between the outgoing and incoming pulse it measures the distance to the ground. Knowing the position and orientation of the aircraft at the same time, it is possible to determine the spatial coordinates of each registered point, giving a topographic point cloud. Flying height and LiDAR instrument determine the point density of all measurements. This can go up to multiple points per square meter.

From the topographic point cloud, highly accurate elevation products are derived opening various applications like flood plane modelling, determining the height of power lines, water management such as hydrological and drainage studies and for infrastructure design and maintenance. Aerodata can execute LiDAR missions in combination with a digital photo camera, in which case flying is restricted to day-time missions. When only flying the LiDAR system, missions can be flown during night-time thus making use of an extended time-window with most stable atmospheric conditions. It offers a cost effective solution to wide area surveys which are impossible, difficult or expensive to access or complete using conventional terrestrial systems.
