Geography is the study of the earth that includes both the physical and
human environment. For geographers, the focus of study is place, and
Geographic Information Systems (GIS) are tools that are used to
study and analyze places in order to understand how objects or events are
geographically distributed and related. GIS
software functions like a geographical database package, where
data exists not only as a series of tables but also visually in the
form of map layers. GIS can be used to produce maps, perform
geographical analysis, and create new data. Geographic Information
Science is the study of both the theoretical and practical aspects of
GIS.
