Geographic Information Systems (GIS)

What is GIS ?

A geographic information system, or GIS, combines maps, data, and computer tools. It helps people collect, store, and study information tied to a specific place. GIS turns this information into maps, charts, and reports. This makes it easier to spot patterns and connections in the data. GIS helps people answer questions, solve problems, and make decisions based on clear, visual information. (Source: Esri)
