The Indian railways will use LiDAR technology –which involves conducting an aerial survey, and is known to give accurate data on the contours of land, even below vegetation- to expedite work on India’s first high-speed train corridor between Mumbai and Ahmedabad. The use of Light Detection and Ranging, or LiDAR, will allow to conduct the survey of the 508km corridor to be completed in 9-10 weeks against the normal 6-8 months. This will help the national transporter start ground work on the Modi government’s dream project by 2016.
The survey will be done using a helicopter to carry the equipment including a high –resolution digital camera, a laser scanner and a data recorder. The Lidar survey is among four surveys- geo technical investigation, hydrological survey and land plan preparations- being conducted by Rites at a cost of Rs 40 crore to finalise the alignment of the corridor.
