Why in News?

  • Recently, the Ministry of Agriculture and Department of Space signed a Memorandum of Understanding (MoU) to develop a Krishi-Decision Support System (Krishi-DSS) using satellite data.
  • This will enhance the evidence-based decision-making capability of all the stakeholders in the agriculture sector by way of integration with MOSDAC and BHUVAN (Geo-platform) and ICAR systems.

 

What is BHUVAN portal?

  • Bhuvan (means earth in Sanskrit) is a Geoportal platform developed by the Indian Space Research Organization (ISRO) and was launched in 2009.
  • It is known for its association with the Government of India to enable the use of Geospatial technology.
    • Geospatial Technology is an emerging field of study that includes Geographic Information System (GIS), Remote Sensing (RS) and Global Positioning System (GPS).
    • It enables us to acquire data that is referenced to the earth and use it for analysis, modelling, simulations and visualization.
  • It hosts a wide range of services that cover visualization of satellite data, thematic maps, free data downloads, near real-time disaster services, apps for crowd sourcing and diverse geospatial applications.
  • Bhuvan has since its inception enabled the Indian government to host public geospatial data as information layers for visualization and public consumption. g., Toll Information System for National Highways Authority of India.
  • The information for the platform is obtained from the Government of India sources or through Crowdsourcing.

What is MOSDAC (Meteorological and Oceanographic Satellite Data Archival Centre)?

  • It is a data repository for the missions of the ISRO and Government of India, dealing with meteorology, oceanography and tropical water cycles.
  • Data acquired from missions is disseminated in near real time from Space Applications Centre (SAC), Ahmedabad through the MOSDAC website.

 

What is a Decision Support System (DSS)?

  • A DSS is an interactive software-based system used to help decision-makers compile useful information from a combination of raw data, documents and personal knowledge, to identify and solve problems and to make an optimized decision.

 

About Krishi-Decision Support System (Krishi-DSS):

  • It is being developed on the lines of Gati Shakti, using RISAT-1A and VEDAS of the Department of Space.
    • Earth Observation Satellite - 04 (EOS-04, formerly known as RISAT-1A) is an ISRO Radar Imaging Satellite designed to provide all-weather high-quality images for applications such as Agriculture, Forestry, Soil Moisture, Hydrology and Flood mapping.
    • Visualization of Earth Observation Data and Archival System (VEDAS) provides a platform (data, infrastructure and guidance) hosted by SAC for utilization of information from space-borne sensors to support the decision-making system.
  • RISAT-1A data will be extremely useful in developing decision support systems for agriculture, bioresources, environment, water resources and disaster management.
    • Hence, Krishi-DSS help in agriculture to collect and analyze data from a variety of sources with the ultimate goal of providing end users with insight into their critical decision-making process.

 


Q1) What are 4 main components of DSS?

A typical Decision support systems has four components: data management, model management, knowledge management and user interface management.

 

Q2) What is Risat-1 used for?

Radar Satellite-1 (RISAT-1) is a state of the art Microwave Remote Sensing Satellite carrying a Synthetic Aperture Radar (SAR) Payload operating in C-band (5.35 GHz), which enables imaging of the surface features during both day and night under all weather conditions.
