Officials in one of India's fastest growing cities are using unmanned aerial vehicles to update land records in a pilot project that could be rolled out across the country if rules governing the use of drones were simpler, authorities said.

Haryana state's Project Udaan, or flight, is mapping the technology hub of Gurgaon, a satellite town of Delhi, and the towns of Sohna and Manesar in northern India.

The drone images are being used to update decades-old land records, check encroachments and resolve disputes over land and property.
