Introduction
Remote sensing and drone imaging are transforming how India monitors its land, resources, and infrastructure. From agriculture to urban planning, these technologies provide high-resolution, real-time insights, reducing costs and enhancing decision-making. For tech buyers, developers, and innovators, understanding these tools is crucial for staying competitive in India’s growing tech ecosystem.
What is Remote Sensing and Drone Imaging?
Remote sensing involves collecting data about objects or landscapes without physical contact, usually via satellites or aircraft. Drone imaging specifically uses unmanned aerial vehicles (UAVs) equipped with cameras or sensors to capture precise images or data over targeted areas. Together, they provide actionable insights for planning, monitoring, and analysis.
