Mumbai: The MMRDA (Mumbai Metropolitan Region Development Authority) planning to use drones to conduct surveys, on the Metro-V & Metro-VI corridors, before starting construction.
The MMRDA proposes to begin construction for the 24-km long Metro-V (Thane-Bhiwandi-Kalyan) corridor & the 16.5 km Metro-VI (Swami Samarth Nagar-Jogeshwari-Kanjurmarg-Vikhroli) corridor by March next year.
MMRDA Drone Surveys
- The MMRDA has successfully used drone surveys for preparing for the construction of the Metro 2B (DN Nagar-Bandra-Mankhurd) route & the Metro 4 (Wadala-Ghatkopar-Thane-Kasarva-davali) route.
- However, this time it will conduct the Social Impact Assessment (SIA), the Environment Impact Assessment (EIA) & the land acquisition surveys together.
- A senior MMRDA official said,“With Metro 2B and Metro 4, we first conducted the SIA and EIA and then did the survey for land acquisition. While both record different data, the process used is the same. By conducting them together, we will save time and other resources.”
About The Drone Surveys
- The aerial surveys will help the authority to map out the alignment of the two corridors.
- The drone surveys will be quicker & more accurate than those conducted manually.
- Attached with 360-degree cameras, the surveys are said to provide up to 3 millimetre accuracy including details such as distance between the buildings & obstructions like trees, telephone lines & high-tension wires.
- All information is digitised & available in visual format.
