GUWAHATI, June 1: The Northeast Frontier Railway is all set to conduct airborne electromagnetic Lidar Survey at the critical locations of Lumding – Silchar Hill Section.
The survey will be conducted during and after monsoon, which will analyse the critical location in detail for the type of soil strata, stability of slope, presence of natural or formed fault tending any movement of hill, water accumulation beneath the soil strata, formation of slip circle and stability of hill toe.
The survey will be conducted between Lumding – Badarpur section at KM – 45 to KM – 125. Tender for the survey has already been finalised and awarded to a Noida based company, Garudauav Soft Solutions Private Limited.
Airborne ground surface survey and sub-surface Electromagnetic Survey based on robust digital twin based artificial intelligence powered one point monitoring system will be conducted. This will monitor the dynamic geophysical landscape and subterranean environment, which will help in identifying and analysing failure as well as critical areas for preventive maintenance of the track environment without substantive human interventions along weak and vulnerable location prone to land slide/slip. This will be done by using non-invasive sensors i.e. LiDAR, optical photogrammetry, infrared mapping and ground penetrating radar and airborne electromagnetic.
The result or output will be analysed by artificial intelligence software for better comparing of thousands of data generated by survey and remedial measures will be provided for such critical location.
LiDAR (Light Detection and Ranging) technology is used to obtain highly detailed and precise elevation data. A LiDAR survey is conducted using airborne or terrestrial LiDAR scanners to capture the topography of the project area, including the existing railway tracks, nearby terrain, and any relevant structures.
Railway surveying projects involve a range of surveying activities and techniques to support the planning, design, construction, and maintenance of railways. This survey plays a crucial role in ensuring the safety, efficiency and effectiveness of railway transportation systems.
