The 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 the survey of the 508km corridor to be completed in 9-10 weeks against the normal 6-8 months. It will help the national transporter start ground work on the Modi government’s dream project by 2018.
According to the plan, almost the entire corridor will be on an elevated track, except 21km that will be underground. Of the 21km, 7km will be undersea.
The survey will be conducted by a helicopter, which carries equipment, including a high-resolution digital camera (100 megapixel), a laser scanner and a data recorder. Read More…
