With regard to Overhead Lines, compliance with these standards requires first of all detection of accurate localization of existing grid (poles and conductors). In order to reach this scope Terna, the Italian TSO, between 2009 and 2010 run a survey for master data acquisition of the whole national aerial transmission grid (more than 60.000 km) through LiDAR technology. This survey, investigating for each line a corridor 100 m wide, was carried out by helicopter equipped with laser, Inertial Measurement Unit (IMU), digital photo camera, temperature sensors and coupled with ground point OPS, in order to guarantee accuracy. Result of detection is a classified cloud point which describes in 3D and with an accuracy of 50 cm the exact position of poles and conductors, as well as buildings, trees, roads, railways and any other thing inside the corridor surveyed. In the meantime also conductors' temperature and orthophotos are acquired. All the classified laser points are well managed by a customized software that allows several types of analysis, specially related to distances between interferences (buildings, roads, trees, etc.) and catenaries that software itself is able to draw, starting from original measured values, for every condition of temperature. Software includes as well special tools for data export in main standard formats (* .dxf, * .shp, etc.). 3D data acquired, together with additional info related to current loads, allow both simplified and detailed EMF computations and modelling. Main platforms used for simplified automatic calculations are the customized sw and EMF tools, developed by CESI, while detailed 3D analysis are provided through WinEDT developed by Vector. Export in CAD and GIS allows at the same time immediate visual analysis. Data collected and software analysis give Terna the chance to identify all possible EMF risky situations, to produce respect width of 3 μ T required for city planning and to have necessary info available for project of new HV lines. Of course this amount of data is used not only for EMF analysis, but also for other Operation and Maintenance needs. Periodical update of laser data is foreseen in order to take under control the evolution of grid and environment
