Imphal, February 22 2023:
For the first time, North East Frontier Railway has employed Light Detection and Ranging (LiDAR) technology to survey the Imphal Moreh railway line project.
The final location survey of the railway line project carried out through LiDAR (Aerial Ground) technology started from Imphal where a helicopter fitted with state-of-the-art aerial LiDAR and imagery sensors took the first flight from Imphal Airport and captured the data related to ground survey.
It may be noted that during this process, LiDAR sensors 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 a few centimeters.
LiDAR can penetrate densely forested areas, thus revealing the bare earth, which satellite images or other techniques cannot deliver.
Adoption of this technology will reportedly fast-track the survey work, thereby saving considerable time and it will also record every minute detail 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 Pvt Ltd under Ircon ISL (Government PSU).
The project work has been taken up under the leadership of Dr Paramesh Banerjee, renowned Indian scientist.
The currently ongoing survey of the proposed Imphal-Moreh railway line (approximately 110 km) project is expected to be completed within a couple of months.
The railway line from Imphal to the border town of Moreh is part of the proposed Trans-Asia Railway Network and will connect India with Southeast Asia.
The strategic importance of this railway line is expected to boost the infrastructure and connectivity in the region.
