A geographic information system, or GIS, is a computer system for analyzing geographical data. It is capable of capturing, storing, manipulating, analyzing, and displaying data in two- or three-dimensional maps. The system’s ability to combine different kinds of data into a single map allows the user to see relationships between the data that might not otherwise be clear. GIS has a great number of applications in a wide range of areas, such as the planning of public facilities and services.
