Determination of Dangerous Parts of the Energy Transmission Line by the Canopy Height Model Produced from LiDAR Data
Abstract
LiDAR (Light Detection and Ranging) technique is preferable method to determine vertical
metric values of High Voltage Transmission
Lines (HVTL) in global regions and steep land. The importance of these
facilities is increasing day by day because of the necessity of electricity
energy in our daily life. Determination
of vertical heights is an important problem especially in forested areas
after construction. In this study, metric values of vegetation which violate
vertical safety limits under voltage wires were determined by using Canopy
Height Model (CHM) using LiDAR data. As a study area 450x150 m2 was
selected the existing voltage line in the region between Beykoz District and
Çekmeköy located on the Anatolian side of Istanbul. Firstly, it has been made
conductive classification of HVTL that is using LiDAR classification
techniques. Also it is determined the
dangerous limits of trees and vegetation in HVTL vertical oscillation. As a
result the comparison of the values of the vertical elevation with the local methods and obtained from the LiDAR data yielded a Root
Mean Square Error (RMSE) value of 0.36m was found.
