What is GIS?
Simply put, a GIS combines layers of information about a place to give you a better understanding of that place. What layers of information you combine depends on your purpose—finding the best location for a new health service, analyzing environmental crises, viewing similar disease areas in a city to detect a pattern, and so on.
GIS can be used to manage, analyze and present Information about geographically located features, for example such information that can be presented on maps. Such information can be about polluting leakage, nurseries and roads, but also about individuals, vehicles and other things with a defined location. GIS can also be used to deal with other types of information that can be linked to a map.
