What is GIS? (Geographic Information Systems)
GIS (geographic information systems) are software technologies that assist in the storage, retrieval, analysis, and distribution of geographic data. This can include everything from satellite imagery to demographic databases to topographical maps. GIS is an enormously powerful tool for organisations that deal with high-volume spatial data, like real estate developers, insurance companies, telecommunication companies, or the government. GIS is helping map out the future of how we understand our world by better understanding the relationship between people, places, and things.
