Global tech giant Google is building a digital agri-stack using satellite imagery and has started with a base layer that will help identify farm boundaries, a senior official said on Saturday. Data and analysis of this base layer of the stack can be used in a slew of applications like bettering the subsidy payments, farm insurance or farm loans, Manish Gupta, a senior director at Google DeepMind said. ".. we have built the first such model that using satellite imagery analysis can now start to identify field boundaries based on usage pattern start to identify what crops are being grown and so on," Gupta said, speaking at the Mumbai Tech Week here. The model has taken inspiration from UIDAI's Aadhar, ascribing a unique ID to each farm and is intended to act as a base layer of the "digital agri stack", he said. Gupta said it is upon the startups and other agri-tech players to build solutions which will provide loan crop insurance and also subsidies using the data churned out by the .
