a) GIS:

GIS- Geographic information system is a system that can be used to analyze, store and share certain data’s, that represents real objects like roads, trees, waterways or any other geographical landscape.

It is one of the most efficient methods used in Civil engineering in its different fields. For eg- In Construction management, the GIS system can be used to denote the precise location, where the structure is to be constructed. Here the GIS system can give certain factors and favorable conditions at the particular site. The steps undertaken with the help of GIS are, data collection, data analysis and the estimate prepared, based upon it’s dimensions and cross sectional area.

In a geotechnical aspect, GIS can be used to provide adequate data based upon the nature of the soil and size of the foundation and the maximum load bearing capacity.

GIS also plays a major role in GPS functioning. With the help of GIS, we obtain a precise location of a site based upon both longitudinal and latitudinal aspect that that makes it easier to navigate.
