Applications of Remote Sensing
Remote sensing data from NRSC finds diverse applications across sectors such as:
Agriculture
The National Remote Sensing Centre (NRSC) has been actively supporting agricultural planning and management through various techniques such as crop monitoring, yield estimation, and precision farming. To achieve this, the centre leverages satellite-derived seasonal cropping patterns conducts experiments on yield estimation and estimates the net-sown crop area. Additionally, NRSC undertakes agricultural drought assessment studies to provide valuable inputs to farmers in times of water scarcity.
NRSC is constantly involved in developing new techniques and methodologies for providing space inputs for Crop Insurance Decision Support System (CIDSS), crop intensification, mapping, and inventory and assessment of high-value crops. The centre also conducts horticulture inventory and agricultural drought vulnerability assessment to help farmers mitigate potential losses and increase their yield.
To further enhance their services, NRSC is conducting soil-vegetation-atmosphere flux studies over different agroecosystems and pilot studies on hyper-spectral remote sensing applications for crop condition assessment. All these efforts aim to support the agricultural sector in India and help farmers achieve better crop yields and incomes.

Forestry
The use of remote sensing technology has proven to be incredibly beneficial in the field of forestry and ecology. It has enabled experts to map forest cover, assess biodiversity, and detect forest fires, all of which contribute to sustainable forest management practices. With forest resources being scarce and facing significant anthropogenic pressure, there is a growing need to utilize Earth observation technologies to develop prescriptions for sustainable management of these resources. This is especially urgent given India's commitment to the Nationally Determined Commitment for Carbon Sequestration at COP 21. To achieve these national goals, it is imperative to have an improved and advanced inventory of forest resources based on EO.
The Forestry and Ecology studies at NRSC have been focused on developing automated processing of multi-temporal and multi-sensor data, as well as providing a three-dimensional description of the forest structure and its distribution. This includes analyzing forest cover changes, estimating spatial biomass, characterizing community biodiversity, implementing a forest fire alert system, providing inputs to working and wildlife plan preparation, and promoting forest carbon sequestration. These studies are being carried out in close collaboration with MOEF & CC, DBT, FSI, and State Forest Departments to ensure their effectiveness and accuracy.
Disaster Management
The National Remote Sensing Centre (NRSC) has a pivotal role in disaster monitoring and response. It provides real-time satellite imagery that helps to assess the impact of natural calamities and coordinate relief efforts. One of its key initiatives, the Disaster Management Support Programme (DMSP), includes the establishment of a Decision Support Centre at NRSC. This centre effectively monitors natural disasters such as floods, cyclones, agricultural droughts, landslides, earthquakes, and forest fires in near real-time using space and aerial remote sensing inputs. Additionally, the National Database for Emergency Management (NDEM) serves as a national repository of GIS-based databases for the entire country. It is equipped with a set of Decision Support System tools that aid State and Central Disaster Management Authorities in making informed decisions during emergency situations. The NRSC's initiatives are invaluable in mitigating the impact of natural disasters on human life.
