The LiDAR survey for preparation of detailed project report (DPR) for Mumbai-Nagpur High Speed Rail Corridor (approx. 736 km) started today, where an aeroplane fitted with state-of-the-art Aerial LiDAR and Imagery sensors took the first flight and captured the data related to ground survey.
National High Speed Rail Corporation Limited is adopting Light Detection and Ranging Survey (LiDAR) technology which provides all the ground details and data in 3-4 months, whereas this process normally takes 10-12 months.
The ground survey is a crucial activity for any linear 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, 150 meters of area around the proposed alignment is being captured for the survey purpose. After the collection of data, a Three Dimensional (3D) Topographical map of the corridor of the proposed alignment on a scale of 1:2500 will be available for designing the vertical & horizontal alignment, structures, location of the stations and depots, land requirement for the corridor, identification of project-affected plots/structures, Right of Way, etc.
To provide clear pictures of the structures, trees, and other minute ground details, 100-megapixel cameras are being used for the LiDAR survey.
NHSRCL has been entrusted to prepare the Detailed Project Reports for seven (7) High Speed Rail Corridors, and LiDAR survey technique will be used for ground survey in all the corridors.
