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 store, analyzing environmental damage,
viewing similar crimes in a city to detect a pattern, and so
on. (Courtesy of www.gis.com)
