摘要：One of the methods of obtaining highly accurate and current spatial data about the terrain, as well as objects situated on it, is laser scanning.LIDAR (Light Detection and Ranging) is among the most modern, dynamically developing technologies and reveals in surveying new capabilities that have been unachievable in a traditional way so far.The aim of the publication is to show the possibilities of using data from airborne laser scanning to perform the survey and visualization of the energy network, and also identification of hazards which the present network constitutes for the immediate environment using the TerraSolid software package.The survey was conducted for two independent sections of the power line, on the basis of two different clouds of points obtained from the airborne laser scanning.The first one had a density of 16 points/m2, while the other 22 pts/m2.The project was created in an environment of MicroStation V8i software using special overlays – TerraScan and TerraModeler of Finnish TerraSolid Company.The use of the test clouds of different densities was intended to indicate an optimal density of the cloud of points, which allows carrying out a survey and visualization of the energy network based on data derived from airborne laser scanning.The publication presents on particular examples the procedure of vectorization and visualization of the power line and detection of objects within a dangerous distance from it.The possibility of using applied LIDAR data, meeting the industry requirements, to the survey of power lines has been also confirmed.
