What Are LiDAR-Based Drones That Maharashtra Government Will Use To Monitor Mining In Pune?

Maharashtra Revenue Minister Chandrashekhar Bawankule on Saturday said the state government will soon use advanced LiDAR-based drone technology to monitor mining activities, starting with a pilot project in Pune district.

Bawankule said that despite the large-scale excavation of minor minerals such as murum, sand and stone, the government is not receiving the expected revenue.

"There is a significant difference between the figures on paper and the actual excavation. To address this, the state has decided to deploy drones equipped with Light Detection and Ranging (LiDAR) technology for precise mapping and measurement of mining areas," he said.

What is LiDAR technology?

It is a remote sensing method that uses laser light to accurately measure distances and create high-resolution 3D maps of the Earth's surface. It is known to have high accuracy in mapping even in dense forests, rugged terrain or underground areas. It is effective during the day as well as the night. It is mainly used to detect illegal mining and monitor excavation depth. Its other uses are in urban planning, environmental conservation, infrastructure inspections and disaster management.

Where will it be used in Maharashtra?

Bawankule said the pilot project will cover 97 mines in Pune district, where regular drone-based measurements will be conducted. Following its success, the revenue department plans to expand the initiative to other districts in phases, he said.

"Significant mineral excavation is taking place in other districts as well. In this context, accurate data, routine monitoring and prevention of misuse are essential. The technology will not only increase the state revenue but also help maintain environmental balance," Bawankule added.
