An essential step in the design and building of electricity transmission infrastructure is a transmission line survey. To find the best path for high-voltage power lines, extensive fieldwork and data collection are required. Topography, the impact on the environment, land use, and potential barriers like rivers or highways are just a few of the elements that surveyors evaluate. With the help of this data, a route is designed to maximize efficiency and safety while minimizing construction costs, environmental disturbance, and difficult land acquisition situations. Aerial surveys, GPS, and LiDAR are examples of advanced technologies that are frequently used to collect precise data and make sure the transmission line satisfies operational and regulatory criteria.
