The following discussion provides an analysis rationale to determine an optimal flight and control configuration for the estimation of the system calibration parameters. Modern photogrammetric mapping 13 A rigorous analysis should investigate the possibility of recovering the parameters in question while establishing the minimal and optimal control and flight requirements for the system calibration. The system calibration parameters include the mounting parameters and the camera calibration parameters, which are susceptible to change under operational conditions, such as the principal distance (c) and the principal point coordinates (xp, yp) (Jacobsen, 2003).

Typically, the software accompanying an airborne LiDAR system provides functions to read recorded laser ranging, GPS, and IMU measurements and produces georeferenced LiDAR point data by integrating these data. Because every flight only covers a strip of ground beneath the aircraft, stitching of flight strips is performed on the basis of the overlapping portions between strips to produce a complete LiDAR coverage for a survey area. The laser scanner, GPS, and IMU are mounted at the different positions on the aircraft.
