Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers "sense" things about the Earth. Remote Sensing Applications 1. Land Use Mapping Remote sensing data is useful in obtaining up-to-date land use pattern of large areas at any given time and also monitor changes that occur from time to time. It can be used for updating road maps, asphalt conditions, and wetland delineation. This information is used by regional planners and administrators to frame policy matters for all-round development of the region. 2. Weather Forecasting Remote sensing is extensively used in India for weather forecasting. It is also used to warn people about impending cyclones. 3. Environmental Study It can be used to study deforestation, degradation of tile lands, pollution in atmosphere, desertification, eutrophication of large water bodies and oil spillage from oil tankers. 4. Study of Natural hazards Remote sensing can be used to study damages caused by earthquakes, volcanoes, landslides, floods and melting of ice in polar regions. Many times remote sensing will be helpful to predict the occurrence of natural hazards. 5. Resource exploration Remote sensing data is helpful for updating existing geological maps, rapid preparation of lineament and tectonic maps, identifying the sites for quarrying the minerals and helpful in locating fossil fuel deposits.
