Geographic information systems (GIS) let you visualize, question, analyze, interpret, and understand data to reveal spatial relationships, patterns, and trends, which in turn help to inform organizational policy and decision making.
The realization of a GIS project can be conceptualized in 5 main steps: definition of the research question, the design of the methodology, the data gathering, the analysis, the presentation of the results.
Geographic information systemAs a result, civil engineers work with a voluminous amount of data from a variety of sources. Geographic information system (GIS) technology provides the tools for creating, managing, analyzing, and visualizing the data associated with developing and managing infrastructure.

For example, using GIS, a single map could include sites that produce pollution, such as factories, and sites that are sensitive to pollution, such as wetlands and rivers. Such a map would help people determine where water supplies are most at risk. GIS applications include both hardware and software systems.Jun 21, 2017
GIS: a formal definition “A system for capturing, storing, checking, integrating, manipulating, analysing and displaying data which are spatially referenced to the Earth. This is normally considered to involve a spatially referenced computer database and appropriate applications software” 7.
