Aerial Survey To Prepare DPR For East Coast Dedicated Freight Corridor

Dedicated Freight Corridor Corporation will be adopting the light detection and ranging survey (LiDAR) technique using laser-enabled equipment mounted on a helicopter to conduct the ground survey for the preparation of the detailed project report (DPR) for the proposed 1,115 km East Coast Dedicated Freight Corridor.

The corridor originates in Kharagpur in West Bengal, traverses Odisha, and terminates in Vijayawada (Tenali) in Andhra Pradesh. It will connect cities/towns like Baleshwar, Bhadrak, Khordha, Bhubaneswar, Rajahmundry, Visakhapatnam, Nellore, and Vijayawada.

During the aerial LiDAR survey, 300 metres of area around the proposed alignment will be captured for the survey purpose. After the collection of data, three dimensional (3D) topographical map of the proposed corridor’s alignment on a scale of 1:2500 will be available for the design of the vertical and horizontal alignment, structures, location of the stations and depots, land requirement for the corridor, identification of project affected plots/structures, right of way, and so on.

Keeping in mind the magnitude of the project and adhering to the timelines to submit the DPR of DFC corridor, reference points on the ground have already been marked and data collection through equipment mounted on a helicopter will commence from the start of the upcoming week (depending on the weather conditions) in a phased manner.

The requisite permissions from the Directorate General of Civil Aviation (DGCA) and Ministry of Defence for flying the helicopter have been received and the inspection of the aircraft and equipment are underway.

Aarvee Associates (Consultant) has been entrusted with preparing the DPRs for three DFC corridors, and the LiDAR survey for other two corridors shall commence shortly.
