The Maharashtra government is using drones mounted with high resolution cameras to speed up the exercise of mapping villages and towns in the state. The government has launched a pilot project to survey these areas with the help of camera-fitted drones, a revenue department official told PTI. Mapping was earlier carried out manually, but the drone technology is now changing the way this massive exercise is undertaken. Once extended to other areas and completed, the process is also expected to boost revenue collection for the government. The project was launched in Sonori village in Purandar tehsil of Pune district.
