Geographic information systems (or GIS) is a complex computer system that can be used to store, integrate, and express data that describes places and features on the Earth’s surface. Information is typically grouped in data “layers” which a GIS user can choose from when creating a map. What the map looks like in the end depends on the intended use. Layers can express information about political, ownership, and watershed boundaries; rivers, streams, and wetlands; and transportation data such as roads, railroads, trails, and airports, including relative route names and numbers, length, and maintenance schedules.
There are many other layers that can be called upon by using GIS. In fact, there are so many features on the Earth’s surface that even the world’s fastest computers could not store all the information for a given area.
GIS is a powerful, yet flexible, tool that allows the user to sort through this complexity and pull out information specific to a question, an issue, or the place they live.
