Delhi-Varanasi High-Speed Corridor: Laser Technique Adopted For Ground Survey

In order to conduct the ground survey for preparing the detailed project report (DPR) of the proposed Delhi-Varanasi high-speed rail corridor, light detection and ranging survey (LiDAR) technique using laser enabled equipment mounted on a helicopter will be adopted, said the National High-Speed Rail Corporation Limited (NHSRCL). The aerial LiDAR survey technique was adopted for the Mumbai-Ahmedabad high-speed rail corridor due to its high accuracy, which was the very first time when this method was used for any railway project in the country. The data provided through the LiDAR technology can be useful for several projects including surface transport, roads, irrigation, landslides, canals, city planning, etc.
