Imphal, February 22 2023:
For the first time; Northeast Frontier Railway (NFR) is using the most modern survey technology for the Imphal Moreh railway line project.
LiDAR (Aerial Ground) for final location survey of Imphal-Moreh railway line project started from Imphal where a helicopter fitted with state of art aerial Light Detection and Ranging (LiDAR) and imagery sensors took the first flight from Imphal airport and captured the data related to ground survey.
LiDAR sensor, mounted on a specially equipped helicopter scans the ground surface using laser beams and measures heights and positions of millions of points on ground surface with an accuracy of few centimetres.
The LiDAR can penetrate densely forested areas, thus revealing the bare earth, which satellite images or other techniques cannot do.
Adoption of this technology will fast-track the survey work, thereby saving considerable time and will also record every minute of the ground features.
During this survey, details of 5 km (2.5 km on either side) of the proposed alignment are being captured.
Based on the findings of the survey, design of the vertical and horizontal alignment, structures, locations of the stations and depots, land requirement, identification of project affected plots/structures will be decided.
The project is being executed by Skylark Designer & Engineers Private Limited under Ircon ISL (Government PSU).
The work is taken up by renowned Indian scientist Dr Paramesh Banerjee.
The final location survey of the proposed Imphal-Moreh railway line (approximately 110 km) project is currently Underway and is expected to be completed within a couple of months.
The proposed railway line from Imphal to border town of Moreh is part of the trans-Asia railway network and will connect India with Southeast Asia.
The proposed railway line is strategically important and is expected to boost the infrastructure & connectivity in the region.
