Applications of remote sensing:-
Remote sensing is widely applicable in the following areas.
1) Applications of Remote sensing with respect to natural hazard. e. g In case of flood,earthquake ,volcano eruption and related hazards, land slides, Tsunami, cyclone, etc.
2) Environmental application: Series of satellite used for weather forecast i.e. cyclone, cloud, wind velocity, sea states, pollution, global warming, and ozone layer depletion.
3) Land use and land cover Analysis: Land use for Urban purpose agricultural sea forest etc. particular cropping pattern, spread area.
4) Archaeology:-To recognize archaeological patterns of prehistoric land use, buried archaeologically important sites.
5) Revision of topo sheets: Rapid revision and updating of existing topo sheets (maps) with help of aerial photography and satellite imagery survey of India department undertake such work.
6) Alignment of (new) highways and rail-lines: - By using aerial photographs and satellite imagery location of most economical alternative sites of such works may be carried out easily.
7) Location of gravity dam sites :- Geological investigation of dam site can be carried at using aerial photographs and satellite imagery (Geological features such as folds, faults, dykes, fractures, rock type)
8) Tunneling: - Geological information (i.e. Faults & fractures) along alignment of tunnel is furnished by aerial photographs and satellite imagery to ensure safety during construction and maintenance of funnel.
9) Silting of storage reservoir, harbors etc.:- Satellite gives imagery idea about silting of reservoir (reduces reservoir capacity) qualitatively and quantitatively and silting of harbor (reduces navigational depth).
10) Location of percolation tanks: To locate exact location of percolation tank from geological investigation of permeable foundation to increase ground water table by using satellite imagery.
11) Seepage losses in canal: By careful study of aerial photograph and satellite imagery, soil moisture in and around the canal system can be monitor and identify the seepage through the canal
12) Location of bridge site: Careful study of aerial photograph and satellite imagery used to analyze existing foundation conditions along the proposed bridge construction site. To find economic and safe alignment of bridge.
13) Study of catchment and command area of dam site: Aerial photographs and satellite imagery used to ascertain the catchment area and command area of dam site.
14) Mineral exploration: Detailed exploration of non –renewable resource like minerals and fossil fuels, geological data, location of minerals, mapping of mineral zones.
