Transmission line final location survey includes tower center layout and surveying and tower site topographic mapping.At present,RTK or CORS-RTK techniques are the commonly used method for surveying.However,in complicated mountainous areas with poor communication network signals,inconvenient transportation,significant terrain fluctuations,and uneven distribution of vegetation,the final location survey work is often hindered by set up reference stations and uneven distribution of network signals,which resulting in inconvenience,increased labor intensity,and decreased efficiency.To address these issues,this study proposes a method combining network CORS-RTK and UAV-borne LiDAR for the final location survey work.The practices show that this method can significantly improve work efficiency and reducing labor intensity,minimize the impact of weather conditions and ensure the accuracy of final location survey,so it can provide practical value and reference significance for the final location survey work.
