Read the given passage carefully and answer the following questions. Satellites are mode of communication in themselves as well as they regulate the use of other means of communication. However, use of satellite in getting a continuous and synoptic view of larger area has made satellite communication very vital for the country due to the economic and strategic reasons. Satellite images can be used for the weather forecast, monitoring of natural calamities, surveillance of border areas, etc. On the basis of configuration and purposes, satellite system in India can be grouped into two: Indian National Satellite System (INSAT) and Indian Remote Sensing Satellite System (IRS). The INSAT, which was established in 1983, is a multi-purpose satellite system for telecommunication, meteorological observation and for various other data and programmes. The IRS satellite system became operational with the launching of IRS-IA in March 1988 from Vaikanour in Russia. India has also developed her own Launching Vehicle PSLV (Polar Satellite Launch Vehicle). These satellites collect data in several spectral bands and transmit them to the ground stations for various uses. The National Remote Sensing Centre (NRSC) at Hyderabad provides facilities for acquisition of data and its processing. These are very useful in the management of natural resources. |
Satellite Images can NOT be used directly for _____. |
Population Enumeration Weather Forecasting Monitoring of Natural Calamities Natural Resource Management |
Population Enumeration |
The correct answer is Option (1) → Population Enumeration Satellite images are extremely useful for weather forecasting, monitoring natural calamities, and managing natural resources. While satellite imagery is increasingly used in conjunction with other data (like census data and AI models) to estimate and model population distribution, it cannot directly enumerate individuals. Population enumeration (i.e., counting people) requires detailed demographic surveys and direct data collection through census operations, which cannot be accurately done using satellite imagery . |
