On Sunday, the National High-Speed Rail Corporation Limited (NHSRCL) launched the LiDAR survey for the Delhi-Varanasi route from Uttar Pradesh’s Greater Noida, whereby a helicopter fitted with state-of-the-art aerial LiDAR and imagery sensors will seize knowledge associated to the bottom survey alongside the proposed route.

Gaur stated that the LiDAR survey will seize knowledge of 300 metres (150 metres on both facet) of the proposed railroad alignment space. Thereafter, three-dimensional (3D) topographical map of 50-metre hall on both facet of the proposed alignment on a scale of 1:2500 might be made out there to design vertical and horizontal alignments, constructions, location of stations and depots, land requirement for hall, and identification of project-affected plots/constructions, and proper of means and many others.
The NHSRCL official stated that as per 9 customary benchmarks set by the Survey of India on this subject, 86 grasp and 350 secondary management factors have been established. These coordinates are used to fly the chopper on the Delhi-Varanasi HSR hall route.
“To provide clear pictures of structures, trees and other minute ground details, 60 megapixel cameras have been used in the LiDAR survey,” she stated, including that the NHSRCL has been entrusted to organize the Detailed Project Reports for seven high-speed rail corridors.
