Abstract
This report presents the mathematical solution for the treatment and use of data from a GPS with the laser cloud mapper (LCM) system. The conversions from GPS coordinates (longitude, latitude and altitude, LLA) to the Earth centered, Earth Fixed (ECEF) coordinates, and vice versa are described. To obtain GPS coordinates of lidar measurements, five on site points, both GPS (LLA) and LCM (range, azimuth, elevation) coordinates are to be measured and used to derive the transformation matrix of one coordinate system to the other. The same transformation matrix and the GPS coordinates of the scanner are used to derive the GPS coordinates of each lidar measurement point. Guidance is provided on how to use the graphical user interface in order to collect the experimental information and calculate the required transformation matrix.
