Application of Remote Sensing
Many applications of remote sensing can be grouped into the following:
a. Resource exploration
b. Environmental study
c. Land use
d. Site investigation
e. Archaeological investigation and
f. Natural hazards study.
A. Resource Exploration: To study the formation of sedimentary rocks and detect oil fields identify deposits of various minerals, and identify underground storage of water, Geologists use remote sensing. For recognizing potential coral reef mapping fishing zone and to find other wealth from ocean. Remote sensing is used
B. Environmental Study: To study cloud motion and predict rains remote sensing is used. With satellite data it is possible to study water discharge from different industries to determine harmful effects and dispersion, if any, on living animals. Oil slicks and Oil spillage can be studied by using remote sensing.
C. Land Use: Mapping of larger areas is possible in short time by remote sensing. Agricultural area, forest area, residential and industrial area may be regularly measured and monitored. It is possible to determine areas of different crops.
D. Site Investigation: In site investigations remote sensing is used extensively for bridges, dams, pipelines. It may be used to locate construction materials such as sand and gravel for the new projects.
E. Archaeological Investigation: Many structures of old era are buried under the ground and are not known now. But, remote sensors are able to identify the buried structures of archaeological significance by studying changes in moisture content and other characteristics of the buried objects and upper new layer.
F. Natural Hazard Study: the following natural hazards can be predicted using remote sensing to some extent and hazards minimised:
1. Earthquake
2. Volcanoes
3. Landslides
4. Floods and
5. Hurricane and cyclones.
