Indian Remote Sensing (IRS) satellites are Earth observation satellites used for various applications involving surveying and monitoring the Earth’s surface. Statement 1 (Assessment of crop productivity), Statement 2 (Locating groundwater resources), and Statement 3 (Mineral exploration) are all standard and significant applications of remote sensing data obtained from IRS satellites. Statement 4 (Telecommunications) is incorrect as telecommunication services are provided by communication satellites (like the INSAT or GSAT series). Statement 5 (Traffic studies) is also a potential application using high-resolution remote sensing data for urban planning and infrastructure monitoring, but given the options, the most prominent and core applications listed are 1, 2, and 3. Option A includes 1, 2, and 3 only, which are definitive applications.

Indian Remote Sensing satellites are designed for monitoring and mapping the Earth’s resources and environment. Their applications include agriculture, water resources, forestry, geology, land use mapping, disaster management, and urban studies.

India has one of the largest constellations of remote sensing satellites in the world. These satellites provide crucial data for various national development activities and research purposes. While traffic studies can potentially use remote sensing data (e.g., satellite imagery for mapping roads, analyzing traffic flow patterns in urban areas), the primary established applications listed among the options are resource identification and management (1, 2, 3).
