A CASE EXAMPLE FOR LASER DATA TREATMENT TO STUDY ROCKY FACESWITH PROTECTION BARRIERS

LIDAR is a useful technique for natural and architectural metric surveying. Acquisition is the first step in laser surveying. The second step is the data treatment that is necessary to obtain a correct digital model of the object. This set of elaborations can be subdivided into preliminary data treatment and creation of the final model. The first operations provide a single noise-free point cloud in a specific reference system. The elaborations studied to reduce the noise in laser data due to the location of protection barriers on the rocky faces of the Longeborgne mountain (Switzerland) are here explained.
