Exp) All of the above are correct. The Terrestrial Observation and Prediction System (TOPS) is modeling software system that brings together various technologies in information technology, weather/climate forcasting, ecosystem modeling, and satellite remote sensing to enhance management decisions related to forest fires, human health, floods, droughts and crops, range and forest production. 

TOPS brought together a system of collecting weather and climate data through satellite remote sensing, ground weather stations, human inputs and using climatic forecasting and ecosystem models for risk determination of crop insurance, crop assessment, sampling of crop yield, early assessment of crop loss, categorizing the risk-prone regions and more significantly, forecasting the climatic conditions in such zones.

  • Significantly improve the quality of services for mobile and internet.
  • Develop a Broadband Readiness Index (BRI) to measure the availability of digital communications infrastructure and conducive policy ecosystem within a State/UT.
  • Creation of a digital fibre map of the Digital Communications network and infrastructure, including Optical Fiber Cables and Towers, across the country.
  • Laying of incremental 30 lakhs route km of Optical Fiber Cable and an increase in tower density from 0.42 to 1.0 tower per thousand of the population by 2024.
    • The Centre will work with States and UTs for having consistent policies pertaining to expansion of digital infrastructure including for Right of Way (RoW) approvals required for laying of optical fibre cable.
