Lidar Data Collection

AAMS has significant experience in LiDAR (Light Detection and Ranging) acquisition with data collected throughout many years. We capture Airborne LiDAR data and Vertical aerial Imagery simultaneously on a project by project basis each ranging in project area coverage from a few square kilometres to hundreds of square kilometres

LiDAR, also known as airborne laser scanning (ALS), is a cost-effective alternative to conventional ground surveying for medium to large scale terrain modelling projects and accuracies achievable are far superior to photogrammetric mapping. Dense sets of discrete elevation points are captured that represent a sampling of the surface. Light is transmitted out to the target which is reflected back to the instrument where it is analyzed. The change in the intensity of the light enables some properties of the target to be determined. The time for the light to travel out to the target and back to the LiDAR is used to determine the range to the target. The final results consist of a rich set of elevation data that can be used to produce high-resolution maps and 3D models of natural and man-made objects
