Geographical Information System
What is a GIS?
Remember those multi-layered images of the human body from middle school science class, showing the body's skeletal system, nervous system and so on? GIS is similar. It layers 20th century geographical maps - of streets, buildings, neighborhoods, even subterranean infrastructure - using 21st century technology.
GIS technology works by linking information stored in databases to a place or location. Users can question the data and present the answers in maps, tables and other graphic representations. Since 80% of all information has a geographic component, the power of GIS can be widely used to support decision-making and problem solving across all sectors - public, private, and not-for-profit.
