Nowadays, the Geographic Information System (GIS) technology has become more popular and is now widely used in earth sciences and environmental. It is a huge and rapidly growing industry and market all over the world, with huge demand for knowledge, experience, information, data, and GIS software products. Project managers, environmental scientists, legislators, activists, and the public are curious about what is the technology of the GIS, and how it can help them with cases or projects. Professionals of GIS are interested in learning of basics of earth sciences and environmental to apply GIS technology in these sciences and other related disciplines. This paper start from the introduction about GIS and various applications, and these applications divided into Overlay of layers, Land Information, Utilities and Infrastructure, Environmental, Archaeology, Natural Hazards, Military, Oceanography, Water Resources, and Agriculture. Finally, we are trying to give conclusions about this research. This paper gives an overview of the application and uses related to GIS. GIS techniques are very useful for various kinds of applications such as for Education, Medical, Tourism and Archeology, Urban Planning, Temperature, water harvesting, Change Detection, and Business. So the use of GIS is the most interesting research topic in recent years.
