Hi-Tech Survey to be used by Railways for Train Corridor between Mumbai and Ahmadabad

LiDAR technology will be used by the railways which will involve aerial survey conduction for the high-speed train corridor between Mumbai and Ahmadabad. The technology is expected to provide accurate data on land contour even below vegetation.

LiDAR or Light Detection and Ranging technique will allow the railways to survey the 508km corridor which will be completed with 9 to 10 weeks against the normal 6 to 8 months. This is expected to help the railways start ground work on the dream project by the Modi government by 2018.

The entire corridor will be on an elevated track however, 21km will be underground and 7km will be under the sea.

A helicopter will survey the work. The helicopter will carry a laser scanner, a high resolution digital camera (100 megapixels) and a data recorder.

Executive Director, Railway Board, Mukul Mathur stated that, the full corridor will be covered withi9n a flying time of 30 minutes. He also stated that, preparatory work along with time taken to process the data is high but, still the entire corridor can be surveyed within 9-10 weeks instead of 6-8 months. The entire exercise is quite accurate and data of forests and buildings can also be captured, stated Mathur.
