India: Terra Drone India, an associate company of Japan-based Terra Drone Corporation, one of the largest providers of industrial drone solutions in the world, has completed an aerial survey of 4,200 sq km of agricultural land for the Water Resources Department of the Maharashtra Krishna Valley Development Corporation (MKVDC) in India.
To make the water management more efficient, MKVDC wanted to update its decades-old agricultural maps. The organization also wanted to make sure no crop was being sown by farmers in areas shown as non-irrigated land to avoid usage charges. Since this project had to be completed in a highly-scientific and time-efficient manner, the Maharashtra government roped in Terra Drone India as its technology partner.
A total of 1,085 villages and farm boundaries were identified for surveying using unmanned aerial vehicles (UAVs) or drones. Terra Drone India surveyed an average of 120 sq km of area per day, acquiring images with 2 cm/pixel resolution. Despite numerous weather constraints, aerial data acquisition was completed within 2 months.
Commenting on the benefits of using drones for surveying and mapping, Prateek Srivastava, CEO, Terra Drone India, said, “When we superimposed the aerial images acquired by our drones on the Maharashtra government’s old maps, it was discovered that in some areas, unirrigated land was being used for cultivation purposes, while in others, previously fertile land had been converted into human settlements.”
Detailing how drones lead to transparency and accountability in water management, Wing Commander Polu Sreedhar, COO, Terra Drone India, said, “Traditionally, governments have used human-centric methods of surveying. These methods not only lack verification and evidence, they are also prone to manual errors. Drone surveys, meanwhile, gives organizations clear evidence in the form of aerial imagery which they can use to improve their efficiency and increase their revenue. Further, the drone imagery can be preserved to inform future decision-making also.”
