The proposed plan for Delhi Varanasi High Speed Rail (DVHSR) Corridor will connect Delhi with major cities like Mathura, Agra, Etawah, Lucknow, Raebareli, Prayagraj, Bhadohi, Varanasi and Ayodhya.
With the start of Light Detection and Ranging Survey (LiDAR) Survey, HSR work gathered momentum for DVHSR Corridor.
LiDAR Survey
National High Speed Rail Corporation Ltd. (NHSRCL) is adopting LiDAR technology for the DVHSR survey.
Also, NHSRCL has been entrusted to prepare the Detailed Project Reports for seven HSR Corridors.
LiDAR survey technique will be used for ground survey in all the corridors to provide the ground details faster.
Ground survey is a crucial activity for any infrastructure project as the survey provides accurate details of areas around the alignment.
This technique uses a combination of Laser data, GPS data, flight parameters and actual photographs to give accurate survey data.
During the Aerial LiDAR survey, 300 m (150 m on either side) of area around the proposed alignment is being captured for the survey purpose.
After data collection, 3D Topographical map of 50 m corridor on either side of the proposed alignment on a scale of 1:2500 will be available for designing of the vertical & horizontal alignment, structures, etc
