The project has already begun in three states-Haryana, Maharashtra and Karnataka- and about 300 drones are expected to be roped in. Compare this with the present topographical maps available in public domain, which are at a scale of 1:50,000. Like the decades-old revenue maps, these maps would show the details of village boundaries, canals, agriculture field limits and roads, with a high accuracy of 10 cm, which is critical for land records. That essentially means 1 cm on the map will represent 500 cm on the ground, which is roughly equivalent to showing the boundaries of each house. SOI’s plan is to develop a high-resolution 1:500 Geoid model of the country. The question is: will India’s notoriously statist establishment begin to view the humble map as a public good that should be freely available? And will the secrecy around spatial data make way for a plan like the one unveiled by the UK, whose SOI-equivalent, the Ordnance Survey, announced in 2018 to make taxpayer-funded digital maps freely available for businesses and citizens? “Addresses in India are very hard to determine unlike other countries," he says.Ī national base map layer will, thus, limit the need for multiple parallel efforts and transform everything from disaster relief to delivery of goods. Flipkart, for example, uses machine learning to convert addresses into sub-regions, which are essentially neighbourhood names suggested by field executives, says Mayur Datar, chief data scientist at the e-commerce firm. On top of that, every private entity and state government has an in-house mapping effort. This amounts to $34.45 billion each year. According to a report by McKinsey Global Institute, land market distortions in India lead to a 1.3% loss in GDP annually. The country needs this digital data and we cannot afford to wait anymore," says former surveyor general of India, Swarna Subba Rao.Ī highly accurate, free-to-use map layer of the country which is available in the public domain can be a game changer. “We currently do not have the requisite map data in digital form, which is of high quality and accuracy. And the plan hinges on a medieval instrument/tool: maps.
