India has rapidly emerged as a global leader in satellite imaging, leveraging its advanced space technology to drive significant progress in various sectors. Through the efforts of the Indian Space Research Organisation (ISRO), India’s satellite imaging capabilities have profoundly impacted agriculture, disaster management, urban planning, and environmental monitoring. Here’s a closer look at how India’s satellite imaging is revolutionizing observation and exploration.
Evolution of Indian Satellite Imaging
India’s foray into satellite imaging began with the launch of Aryabhata in 1975. However, it was the Indian Remote Sensing (IRS) satellites, starting with IRS-1A in 1988, that marked a significant leap. These satellites have provided high-resolution imagery for diverse applications, establishing a solid foundation for subsequent advancements. google maps satellite
