Laser enabled equipment mounted on a helicopter for conducting ground survey
Delhi-Varanasi High-Speed rail corridor: The LiDAR survey for Delhi-Varanasi High Speed Rail Corridor started on January 10 from Greater NOIDA where a Helicopter fitted with state of 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 wherein 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.
