GIS and remote sensing techniques have become indispensable and potential tools for solving problems in civil engineering. Data from remote sensing mostly correlate spatial data to their attributes making them useful in this field. Different themes such as geology, terrain, drainage, and hydrology can be extracted by the use of remote sensing. Integrating the above themes helps to solve civil engineering problems faster. Places, where remote sensing in technology is mostly used, include sanitation, urban growth, new road alignment, and irrigation project design. GIS and remote sensing data are mostly used to develop models by integrating socio-economic, demographic and information on natural resources.

GIS Geographical Information System is a system anticipated to capture, analyze, manipulate, store, manage and present every type of geographical data. The merging of cartography, database technology, and statistical analysis is all what GIS means and is the reason why it is has been intensively used in the civil engineering niche. GIS is used more in the mechanical practice of construction industry. In construction during the preparatory phase, the issues of spatial positioning have to be solved cooperatively with the checking of the purposely and feasibility, the traffic projects are operated out and the alternative. GIS technology is gaining interest from a wide range of civil engineering disciplines owing to its potential to offer a new way of resolving environmental difficulties which could reduce costs, support multi-discipline analysis and improve quality for complex projects. GIS in civil engineering provides a dominant location to conduct longitudinal analysis overlay data and assimilate other solutions systems. Fabricated on a database and not in the individual project files, GIS allows civil engineers to effortlessly manage share, reuse and analyze data thus managing time and resources.


Some current uses of GIS and Remote Sensing in civil projects are housing, sanitation, power, water supply, disposal of effluents, urban growth, irrigation project.


Applications of Geomatics in Civil Engineering

Civil engineering has come a long way. From ancient aquifers to locating natural gas deposits via satellite, the oldest branch of engineering in the world has literally left the planet. One technology that empowers modern civil engineers is geographic information systems GIS. GIS enables engineers to capture and analyze spatial data.

Applications of Geomatics in Civil Engineering

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus is in contrast to on-site observation. The term is applied especially to acquiring information about the Earth. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines for example, hydrology, ecology , meteorology, oceanography, glaciology, geology ; it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others. In current usage, the term "remote sensing" generally refers to the use of satellite or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans , based on propagated signals e. It may be split into "active" remote sensing when a signal is emitted by a satellite or aircraft to the object and its reflection detected by the sensor and "passive" remote sensing when the reflection of sunlight is detected by the sensor. Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas.

Remote Sensing and GIS techniques become potential and indispensable tools for solving many problems of civil engineering and terrain. Remote sensing observations provides data on earths resources in a spatial format, GIS co-relates different kinds of spatial data and their attribute data, so as to use them in various fields of civil engineering. Different themes namely, terrain, geology, hydrology drainage, land use and so on can be extracted from remote sensing data. All the above thematic information along with their attributes can be integrated to solve many problems of civil engineering. Some current uses of GIS and Remote Sensing in civil projects are housing, sanitation, power, water supply, disposal of effluents, urban growth, irrigation project design and planning, new road alignment etc. For this Remote sensing and GIS are used to generate development models by integrating the information on natural resources, demographic and socio -economic data in a GIS domain with satellite data.

    In simple terms the civil engineering applications can be divided into two groups: a) human related b) environment related, and remote sensing.
