The Indian Space Research Organisation (ISRO) utilizes various satellites for resources monitoring and management. One of the prominent satellites in this domain is the Resourcesat series, consisting of Resourcesat-1, Resourcesat-2, and Resourcesat-2A. These satellites play a crucial role in monitoring Earth's resources and providing valuable data for effective resource management.

Resourcesat-1, launched in 2003, was India's first satellite dedicated to resources monitoring. It carries three sensors: the Advanced Wide Field Sensor (AWiFS), the Linear Imaging Self-Scanning Sensor (LISS-III), and the LISS-IV Multispectral Sensor. These sensors capture high-resolution multispectral imagery, enabling the monitoring of vegetation, water resources, soil quality, and land use/land cover changes. The data collected by Resourcesat-1 aids in assessing the health of forests, crop monitoring, water resource management, and urban planning.

Resourcesat-2, launched in 2011, is an advanced Earth observation satellite equipped with three sensors: LISS-IV, LISS-III, and the Advanced Wide Field Sensor - 2 (AWiFS-2). These sensors provide improved spectral and spatial resolution, enhancing the accuracy and detail of resources monitoring. Resourcesat-2 enables the assessment of agricultural practices, deforestation, urban sprawl, and natural resource mapping. It also assists in disaster management, including the identification of flood-prone areas and monitoring post-disaster recovery.

Resourcesat-2A, launched in 2016, is a follow-up mission to Resourcesat-2. It carries the same sensors as its predecessor, LISS-IV, LISS-III, and AWiFS-2, offering continuity in resources monitoring capabilities. The satellite provides enhanced imaging and data products for applications such as crop inventory, drought assessment, land cover mapping, and environmental monitoring.

In addition to the Resourcesat series, ISRO also utilizes other satellites for resources monitoring and management. The Cartosat series, comprising Cartosat-1, Cartosat-2, and Cartosat-3, plays a crucial role in generating high-resolution imagery for cartographic applications, terrain mapping, and land use/land cover studies. These satellites contribute to the assessment of resources and facilitate urban planning, infrastructure development, and watershed management.

Furthermore, ISRO's INSAT (Indian National Satellite System) satellites provide valuable inputs for resources monitoring. INSAT satellites carry sensors that aid in weather forecasting, ocean monitoring, and disaster management, which are essential components of effective resource management.

The data acquired by these satellites is made available to various government agencies, research institutions, and the public. ISRO's National Remote Sensing Centre (NRSC) processes and distributes the satellite data, enabling users to derive valuable information for sustainable resource management, agriculture, forestry, water resource assessment, and environmental planning.

Through the Resourcesat series and other satellites, ISRO continues to play a significant role in monitoring and managing Earth's resources. These satellites contribute to informed decision-making, policy formulation, and sustainable development, supporting India's efforts towards efficient resource utilization and environmental conservation.
