Power transmission lines routes mapping is an important technique for locating power transmission line routes andtowers on mountain/hilltops to assist viewing of their impacts on the environment, operations and allocation of publicutilities. A study was therefore conducted to map the power transmission lines within Bukit Lanjan PLUS highway. Themain objective of this study is to assess the capability of airborne hyperspectral sensing for mapping of powertransmission. By using ENVI software, the airborne hyperspectral imaging data was enhanced using convolutionfiltering technique using band 3 which produced a gray scale image which appeared clearer and sharper. The spectralreflectance curves were acquired for each power line which showed the same spectrum characteristics in curve or thereflectance energy. This is because of the same power lines composition material for all power lines. Groundverification was done by comparing the UPM-APSB’s AISA Global Positioning System (GPS) coordinates readingswith ground GPS coordinates readings of the power transmission lines footings. The ground verification result from thetwo matching power transmission line footings showed that the accuracy of power lines identification was acceptable.This study implies that airborne hyperspectral imagers are powerful tools for mapping and spotting of suitable largetransmission towers and lines.
