LIGHT DETECTION AND RANGING (LiDAR) TECHNIQUE

Topic: Government initiative

National Hight Speed Rail Corporation Limited adopts Light Detection and Ranging Survey(LiDAR) technique using Laser enabled equipment mounted on a Helicopter for conducting a ground survey for the preparation of a Detailed Project Report for the proposed Delhi-Varanasi HSR corridor.

ABOUT LiDAR

It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges to the Earth.
These light pulses combined with other data recorded by the airborne system generate precise, three-dimensional information about the shape of the Earth and its Surface Characteristics.

HOW IT WORKS?

LiDAR follows a principle-throw laser light at an object on the earth surface and calculate the time it takes to return to the LiDAR source.
Given the speed at which the light travels, the process of measuring the exact distance through LiDAR appears increadibly fast.
