India is moving forward with its second Bullet train project after Mumbai-Ahmedabad High Speed train corridor. From Friday, 12th March, LiDAR or Light Detection and Ranging survey started for the proposed High Speed Rail Corridor between Mumbai and Nagpur.
It will be part of the Detailed Project Report or DPR. India’s proposed second bullet train project will pass through cities in Maharshtra like Shahapur, Igatpuri, Nashik, Mehkar, Malegaon, Pulgaon, Wardha and Khapri and will be 736-km long, PTI said quoting a release by the National High Speed Rail Corporation Ltd (NHSRCL). The LiDar technology used in the survey expedites the process and the survey with all the data is expected to be finished in just 3-4 months against 10-12 months taken usually for such work, it said.
LiDAR surveys are done by using state-of-the-art technology in which aerial LiDAR and imagery sensors are fitted over an aeroplane and the airborne devises capture the data related to ground survey. High-power 100 megapixel cameras are used in the LiDAR technlogy to get a clear picture of the surrounding structures, trees and other minute ground details and topography.
