The government will soon hold a drone survey of quarries across the State with a view to creating a digital repository of quarries. The process involves quarry mapping, stockpile surveying, volume extraction etc.
A first-of-its-kind initiative in the State, the Mining and Geology department will undertake the survey in association with Keltron.
The department held a pilot study in two quarries in Thiruvananthapuram, where taluk surveyors held conventional surveys using total station method before carrying out LiDAR mapping, a remote sensing survey method using drones. An analysis of the data collected using the two methods proved the new technology is feasible for surveying all quarries in the State, says Harikishore S., Director, Department of Mining and Geology.
