Abstract
 Airborne LIDAR and GIS Tools in Transmission Line Re-Rating Projects Track: Electric and Gas Author(s): Ana Paula Kersting, Juliano Kersting, Carlos Felsky Filho, Mauricio M�ller The growing energy demand is an issue that electric utilities continually face. The construction of new transmission lines is not always possible due to difficulties in acquiring rights-of-way and obtaining environmental approvals. The solution has been to increase the capacity of existing lines. In order to do that, knowledge about the current clearances and available safety margins is necessary for the analysis of the maximum capacity of the line. Airborne LIDAR uses a precise laser scanning technology that provides highly accurate terrain and conductor elevation data for the transmission line corridor. Algorithms aimed primarily at the extraction of necessary information for re-rating projects were implemented using ArcObjects, C## language, and ArcGIS Spatial Analyst, and 3D Analyst extensions. The developed tools allow the analysis of critical distances, obstacles identification, sag calculation, catenary shape determination, video imagery linked with the data, structures location and data exporting to specialized engineering softwares.
