Lidar Lmagery And Its Critical Evaluation For Vegetation Management And Transmission Power Lines
Authors : Ansari R . Sarkar H .
Abstract
The impact of electric power transmission line and vegetation has very effective significance for the power transmission lines. Million of people faced electricity loadshading problem due to shot circuit between vegetation and transmission power lines. In this study LiDAR imagery were used in solving the above stated problems. However all the classification was done by macros but due to misclassification of classes manual classification were also done. The maximum difficulties were found for the lo\v vegetation points which get mixed with ground points and these low vegetation points don 't need to be managed as their height were not going to affect transmission tines. The maximum problem was found with the medium vegetation which encounters power lines and needed proper management. The actual height of the power line is 8.5 mu and average height of vegetation in certain places is > 14.00 mu respectively from the ground. Not only that, high Voltage transmission power lines and low voltage transmission power lines need to buffer unto where vegetation will not cross the buffer zone and need to survey on regularly and priority basis. However, the study reveals that LiDAR provides actual, complete and finest Details and 3D information of power vegetation.
