3. What Is Remote Sensing :
Remote sensing is the acquisition of information about an object or phenomenon without
making physical contact with the object, in contrast to in situ or on-site observation. The term is
applied especially to acquiring information about Earth and other planets. Remote sensing is
used in numerous fields, including geography, land surveying and most Earth
science disciplines (e.g. hydrology, ecology, meteorology, oceanography, glaciology, geology); it
also has military, intelligence, commercial, economic, planning, and humanitarian applications,
among others.
How does Remote Sensing works? :
The majority of remote sensing systems use the sun’s radiation, which is selectively scattered
and seen based on the composition of the atmosphere and the wavelength involved. The items
interact with the radiations that reach the earth. Some of these rays are absorbed, reflected, or
radiated back to the sensors, where they are collected and processed into images, which are
then analyzed to extract information about the objects. Finally, the information gathered is used
to make decisions and solve specific problems.
4. Application of Remote Sensing in Civil Engineering :
The various application of Remote Sensing are discussed below
1.In resource exploration :
Remote sensing is used by geologists to research the origin of sedimentary rocks, identify
mineral resources, locate oil reserves, and locate subsurface water storage. Remote
sensing is utilized to detect possible fishing zones, map coral reefs, and discover other
ocean resources.
2.For environmental study:
Cloud motion and rain prediction are studied via remote sensing. Water discharge from
diverse enterprises can be studied using satellite data to determine the dispersion and if
any, negative impacts on living species. Remote sensing can be used to study oil spills
and slicks.
5. 3.Land use:
Larger areas can be mapped in a short time using remote sensing. Forest, agricultural,
residential, and industrial areas can all be measured and monitored on a regular basis. It
is easy to locate places where various crops are grown.
4.Site investigation/analysis:
For site study, GIS efficiently includes and analyses numerous types of information and
images. It displays precise results that civil engineers can use to quickly communicate
and connect with clients via a simple map. Environmental protection regions, aerial
pictures, and topographic maps are all included in the base map. Civil engineers also
employ remote sensing techniques to forecast future necessities.
5.Study of natural hazards:
Earthquakes, volcanoes, landslides, floods, hurricanes, and cyclones can all be forecast
to some extent and hazards reduced using remote sensing technology. Civil engineers
can use remote sensing techniques to study landslides and other natural disasters. As a
result, they are able to construct buildings such as bridges, roads, and railroads in safe
locations. Landslides can devastate infrastructure, resulting in significant losses. By
incorporating GIS and remote sensing into civil engineering, all of this can be prevented.
6. 6.Town planning:
Towns are sprouting up in practically every part of the globe. Proper planning contributes
to a clean and accessible city. Remote sensing and GIS play a critical role in achieving
this goal. The Geographic Information System (GIS) is in charge of putting resources in
the right places. Remote sensing, on the other hand, aids in the tracking of things like
electricity lines and drainage systems.
7. Urban development:
Almost every country is experiencing rapid urbanization, which is producing issues like
sanitation and housing. Other issues brought on by urbanization include effluent disposal,
water availability, and pollution. Civil engineers, on the other hand, can build proper urban
developments employing suitable remote sensing technology.
7. 12. Water resource engineering:
When it comes to water resources engineering, remote sensing and GIS approaches
have proven to be useful. Dams and other reservoirs require a large amount of data to be
built and shared properly. In addition, it enhances flow control. Civil engineers can build
infrastructure that allows people to get access to water
13. Terrain mapping and analysis:
When it comes to civil engineering, terrain mapping and analysis are quite important. Civil
engineers can use terrain mapping to build better highways. It also aids them in avoiding
unsafe places and identifying the ideal terrains. Road and rail building can be a difficult
task without the use of remote sensing methods.
8. Conclusion:
The rapid technological breakthroughs in the scientific field of remote sensing have
piqued the interest of a variety of fields, including civil engineering, in the underlying
principles, methodologies, and applications that may provide a rich supply of information
useful for a variety of difficulties. Remote sensing has a wide range of civil engineering
applications, including regional planning and urban development, critical infrastructure
protection, natural hazards and environmental challenges, road alignment studies, land
cover/land use studies, water resource management, and so on. As a result, GIS and
remote sensing are becoming more important in civil engineering businesses, enabling
them to support all phases of the infrastructure life cycle.
