LiEagle  is an aerial LiDAR surveying system designed for large area and long-range 3D  data collection projects. The system is designed to be mounted to a  helicopter platform and features a Riegl VUX-1LR laser scanner coupled with a  best-in-class inertial measurement unit (IMU) for increased point cloud  accuracy and precision. The LiEagle is well-suited for projects aiming to map  terrain features beneath forest canopies and extract structural parameters  from forest LiDAR data. The centimeter-level accuracy of this measurement  device will meet the rigorous accuracy demands of civil engineering and  critical infrastructure maintenance professionals. And an optional  high-definition (50 megapixels) digital camera module can be used to generate  photogrammetry products as well as true color 3D point clouds during each  LiDAR survey.
