A geographic information system (GIS) is a computer system that captures, stores, validates, and displays data about locations on the Earth’s surface. Confusing? GIS, to put it simply, is where location and data meet. GIS is used in so many different ways in daily life. Whether we’re talking about a street, building, or landscape, this kind of data may be simply displayed on a map in different layers. GIS enables people and organisations to more clearly grasp geographical patterns and relationships by connecting seemingly unconnected data.
How is GIS applied?
The analysis of numerous types of information is possible with GIS. Data on people, such as their density, income, or level of education, may be included in the system. It may contain details on the topography, such as where streams are, the kinds of plants present, and the kind of soil. It may also contain information on the locations of storm drains, roads, and electricity lines as well as information on farms, factories, and schools. People can associate many areas, such as a factory that pollutes the environment and sites that are directly harmed, like rivers and wetlands, using GIS. People can estimate the danger and determine which water supplies will be directly impacted with the aid of such an analysis.
