Indian Remote Sensing (IRS) satellites are primarily used for Earth observation, providing crucial data for natural resource management and environmental monitoring. This includes assessing agricultural productivity through crop health analysis, identifying potential groundwater reserves by analyzing geological features and surface indicators, and aiding in the exploration of mineral deposits by mapping geological formations. While telecommunications and traffic studies might utilize satellite technology, they are typically the domain of communication satellites (like INSAT) rather than IRS satellites, which focus on imaging and data acquisition for other applications.
