Chennai: An unique project to map Chennai using drones began in late 2017 after receiving a slew of clearances from various ministries of the Union Government, including the defence and home ministries.
Chennai became the first municipal corporation in the country to undertake such a project and has received ₹6 crore in World Bank funding.
The drones cover around 7 sq km a day and collect images with a resolution of up to 5 cm. Even potholes, signboards and small encroachments of footpaths can be seen.
The project is not only expected to through light on encroachment of government land, which is a serious problem in Indian cities. The project will also enable for a better levy of property tax to shore up the finances of the city. It would also help in better management of disasters.
Around 36,000 digital images can be captured per day with the drones and the manpower available, say officials.
This mapping of the city is expected to form the basis for digitisation of various assets held by the corporation and their easy management.
