Q1) (c)

Define remote sensing. Give applications of remote sensing.


Remote sensing is art and science of obtaining information about an object or phenomenon through an analysis of the data acquired by a device is not contact with the object, area or phenomenon under investigation.
‘Remote’ means far away and ‘sensing’ means believing or observing or acquiring some information. So, remote sensing means acquiring information of objects from a distance.


Remote sensing has application in a wide spectrum of areas. Remote sensing affords a practical means for accurate and continuous monitoring of earth’s surface and activities.
Some of application areas are given below:
  • Agriculture: Crop statics, management system analysis and horticulture.
  • Forestry: Forest area, types and density, biomass, and grassland.
  • Environment: Impact analysis, wetlands, pollution and abatement.
  • Coastal mapping: Coastal land use, landforms and habitat process.
  • Marine application: Potential fishing gene, forecast modelling, primary productivity.
  • Urban environment: Road development planning, route analysis.
  • Land & water resources: land and water conservation and development, groundwater targeting, snow melt, runoff recharge.
  • Geology: mineral targeting, oil exploration, mapping, groundwater studies.
  • Land use/ land cover: mapping development and planning.
  • Information: integrated spatial and attribute data, query and modelling.
