A geographic information system (GIS) captures, stores, analyzes, manages, and presents data that is linked to location. This allows us to view, interpret, and visualize data in many ways that reveal relationships, patterns, and trends between the data. Because viewing data in a visual way is very intuitive for humans a GIS helps us to answer questions and solve problems by looking at data in a way that can be quickly understood and easily shared.
