New Delhi, Jan 17 : A week after the National High Speed Rail Corporation Ltd (NHSRCL) carried out an aerial LiDAR survey of the 800 km Delhi-Varanasi High Speed rail corridor, the work on the survey for Delhi-Ahmedabad and Mumbai-Nagpur are also slated to be launched soon as the tenders have been awarded, officials said.
NHSRCL spokesperson Sushma Gaur told IANS: Tenders related to data collection and various other activities including LiDAR survey, required for the preparation of Detail Project Reports for Delhi-Varanasi, for which the first draft of the DPR has already been submitted.
According to NHSRCL, the ground survey is a crucial activity for any linear infrastructure project as the survey provides accurate details of areas around the alignment. The technique uses a combination of laser data, GPS data, flight parameters, as well as actual photographs to provide accurate survey data.
The aerial LiDAR survey technique was adopted for the Mumbai-Ahmedabad high-speed rail corridor due to its high accuracy, which was the very first time when the method was utilized for any railway project in the country. The data provided through the LiDAR technology can be useful for several projects including surface transport, roads, irrigation, landslides, canals, city planning, etc. In order to provide clear pictures of the structures, trees, and other minute ground details, 60-megapixel cameras are being used for the LiDAR survey.

Over three years after Prime Minister Narendra Modi laid the foundation stone of India s first 508-km Mumbai-Ahmedabad High-Speed Rail corridor, the work on the second such rail corridor in the country on the Delhi-Varanasi route has gained momentum.
An aerial LiDAR survey of the 800-km Delhi-Varanasi High-Speed Rail (DVHSR) corridor has now been undertaken by the Railways as part of the project to connect Modi s parliamentary constituency with the national capital through the bullet train.
On Sunday, the National High-Speed Rail Corporation Limited (NHSRCL) launched the LiDAR survey for the Delhi-Varanasi route from Uttar Pradesh s Greater Noida, wherein a helicopter fitted with state-of-the-art aerial LiDAR and imagery sensors will capture data related to the ground survey along the proposed route.
